The Extension, which will be physically connected to the Baclaran Station of the existing line will operate on fully elevated dual tract guideway from Baclaran, Parañaque City to Bacoor in the Province of Cavite, with provision of another further to the south to Imus and Dasmariñas. It will utilize a technology that is compatible with that of the existing LRT Line 1 and its 100 % capacity extension. The extension line, consisting of ten (10) passenger station, three (3) intermodal facilities at Dr. Santos, Zapote, and Niog Stations, and a satellite depot in Bacoor, Cavite, will serve the southern area of Metro Manila and the northeast corner of the Province of Cavite. The estimated capital cost for the proposed Extension is $ 597,000,000.00 The LRT Line Extension Route The route from the Baclaran Station of the existing LRT Line 1 will turn west at Redemptorist Road towards Roxas Boulevard. At approximately 6.5 meters from the seawall, the line deflects south, traversing the reclaim area along the west side of Roxas Boulevard until it reaches Asia World, where it veers on an easterly direction to follow the course of Parañaque River. The Extension will directly traverse the middle of the said river to avoid concrete structures and shanties on both sides. The alignment will maintain its course until it reaches the river bend in Brgy. La Huerta where it deflects on an southerly direction to merge with the existing Ninoy Aquino Avenue. Using the median of the avenue, the alignment continues south crossing the San Dionisio River, then join Dr. Santos Avenue. Page 18 ii The route then leaves the avenue, turning southwest, crossing the site of the proposed C-5 Highway, onto the salt beds and fishponds areas in Manuyo Uno, Las Piñas City. The Extension Continues southwest then cross the Golden Haven Cemetery, then pass through some built-up areas near Tramo Bridge at Pulang Lupa I, until it reaches Padre Cera Bridge at Quirino Avenue. The alignment will then traverse the southern bank of the Las Piñas River, and then again cross some marine ponds in Pulang Lupa I, then cross Zapote River in Brgy. Longos, Bacoor, Cavite. The alignment maintains its direction crossing under the Coastal Road Flyover, then deflects on a southerly direction to join with the Talaba Diversion Road. The route continues south traversing the median of Talaba Diversion Road then cross the intersection of Gen. E. Aguinaldo Highway and Talaba Diversion Road and head towards the end of the first phase of the project at Brgy. Niog, Bacoor, Cavite. Brief Description of Data Gathering The Study was conducted from April to September 1999. The approach and methodology adopted are based on the Procedural Flow of the Environmental Impact Statement (EIS) System prescribed under Article III of the DENR Administrative Order NO. 96-37, series of 1996. Data Gathering and Collection · Primary data gathering procedures was employed to established baseline information on the project site, particularly with respect to the vegetation, ambient air, noise and water quality, geology and geomorphology, and socio-economic aspects. · Since the project area is well studied, available published and unpublished literatures were also utilized. Several government offices/entities such as the City Government of Pasay, Parañaque and Las Piñas, Provincial Government of Cavite, Municipal Government of Bacoor, Page 19 iii Cavite, PAGASA, PHIVOLCS, Mines and Goesciences Bureau (MGB), Bureau of Soils, DPWH Southern Manila Engineering District, were visited to gather the necessary information. Project Screening and Scoping · 1 st Level Scoping of the Proposed LRT Line 1 Extension Project was held on 22 April 1999 at the EMB Conference Room. The meeting was conducted to determine the appropriate scope and level of environmental assessment to be used for the proposed project, and also to ensure the project’s compliance with the procedural requirements of the DENR for the issuance of the ECC. · The Guidelines for Public Participation and Social Acceptability prescribed in the DAO 96-37 regarding the conduct of the social preparation activities was adopted. Presentations of the project were rendered to the Barangay Officials of the areas that will be traversed by the project. The consultations and briefings provided the venue for active participation of concerned sectors in project planning and decision making. · Three (3) Formal Scoping Sessions were conducted at different venues. All the meetings were well represented and attended by the stakeholders in the project area. After the Open Forum, the Agreed Upon Studies To be Undertaken and Agreed Upon Issues to be Addressed by the EIA were signed by the stakeholders. (Please refer to the submitted Scoping Report). · A Scoping Report was prepared and submitted by the EIA Team to the EMB (Environmental Management Bureau) on. July 1999. Brief Description of Project Environment The Direct Impact Area (DIA) refers to areas within the construction limit (within the Right-of-Way) that will be directly affected by the construction activities, i.e., areas where houses and improvements will need to be demolished/removed. The Indirect Page 20 iv Impact Area (IIA) on the other hand refers to areas which will be indirectly affected by impacts such as increase in noise levels and TSP levels, traffic congestion, and the like. Physico-Chemical Aspects Geormorphology The project area lies on the delta plain bounded by the Manila Bay on the west, the western flank of the Guadalupe Plateau on the east, and the slopes of the Tagaytay highlands at the south. The slopes of these highlands serve as the catchment areas for the river systems that bise cts the project area. The Parañaque and Las Piñas River, and their tributaries drain from the slopes of the Guadalupe Plateau. Zapote River drains from the Tagaytay Highlands. The geomorphologic features of the area include tidal flats, backswamps, beach ridges/coastal dunes, and, alluvial lobes and crevasse splays. At present, the plain fully developed and highly urbanized, which altered the inherent features of each geomorphic unit. Geology Based on the environment of deposition, the sediment deposits in the project area can be classified into six (6) Lithologic Units namely, abandoned channel deposits, active channel deposits, backswamp deposits, beach sand deposits, tidal flat deposits fill and reclamation materials. Based on records, Metro Manila had experienced numerous earthquakes in the past. On the average, Manila is likely to be hit by a perceptible (Intensity IV) earthquake every year and by a destructive earthquake once every 15 years . A rough estimate of the average return period for Intensity VIII earthquake is about 79 years based on five events that occurred from 1599 to 1970. Records also show that four (4) extremely strong events (Intensity IX) occurred from 1645 to 1863 with an average return period of Page 21 v 54 years. An extremely strong earthquake has not shaken the metropolis for the last 130 years. However, available instrumental data during the last century suggest that the return period for such big earthquake could be as low as 250 years (J.A. Daligdig & G.M. Besana 1993) The more important potential earthquake generators likely to affect the Metro Manila area are the Manila Trench, Philippine Fault, Lubang Fault and the Marikina Fault. The existing geological, geomorphic and tectonic conditions posses certain geological hazard that will affect the project. These include 1) ground shaking, 2) ground rupture, 3) liquefaction, and 4) flooding. The first three are directly caused by earthquakes due to the presence of earthquake generators near the area, the last is consequent to the areas geologic and geomorphic setting. Surface Hydrology Drainage within the route corridor is served by three (3) major drainage system (i.e. Parañaque, Las Piñas, and Zapote Rivers) that empties into the Manila Bay through two (2) main outlets. Within the coastal plain, the river course is morphologically controlled, running parallel to the coastline following the land ward boundary of the beach ridges and exhibits a meandering coarse. This area also acts as natural catch basin surface water coming from the flanks of Guadalupe Plateau and Tagaytay Highlands. The flow in the coastal Plain is generally sluggish, dominated by standstill water condition. This is mainly caused by the influence of tidal fluctuations and the terrain’s flat topography with elevation ranging from 2 meters below sea level in some sections just to 3 meters above sea level. General Land Use General land use types in the Project Area (Cities of Pasay, Parañaque, and Las Piñas, and Municipality of Bacoor) mainly consists of the following : ( i ) Low to Medium Page 22 vi Residential, ( ii ) Mixed Residential/Commercial, ( iii ) Industrial, ( iv ) Mixed-Use Agricultural, and ( v ) Reclamation Area. Due to its proximity to the business districts and highly urbanized areas of Metro Manila such as the Makati Central Business District (CBD), the Ortigas Sub-Urban Center, and the Manila CBD, it has become an extension of these growth areas, and is rapidly developing into suburban communities and satellite subcenters. Water Quality The results of the laboratory analyses show that all the samples exceeded the DENR Standard for the 5- day 20º BOD level, which is 7 mg/l , except for the water sample taken from Zapote River in Las Piñas City. Water samples from the San Dionisio and Las Piñas Rivers exhibited the highest levels. The high BOD levels indicate that of the river systems are polluted, and thus cannot support higher forms aquatic life. Meteorology The climate in Metro Manila and the Province of Cavite belongs to Type I of the Modified Corona’s Classification. This climate type is characterized by two ( 2 ) pronounced seasons, the wet and dry. Rainy months are from June to September, whereas dry season is experienced from November to April. The highest average monthly rainfall in the project area occurs during the month of August with an average of 463.5 mm, the minimum on the other hand occurs in February. The mean monthly temperature is gauged at 28.0ºC, with the minimum monthly temperature of 24.8ºC, which is experienced in February. The Northeast and Southwest Monsoon, and the North Pacific Trades are the major air streams that significantly affect the study area. The Northeast monsoon prevails from June to September, whereas the Southwest Monsoon predominates from October to May. Page 23 vii Ambient Air quality and Noise Levels Laboratory results show that TSP levels at four (4) out of seven (7) stations exceeded the DENR Standard. On the other hand, TSP concentrations of the rest are well within the standards. Values obtained for other pollution indicators such SO 2 and NO 2 are way below the DENR standard. Noise level measurements shows that all values exceeded the DENR Standards for morning, daytime, evening, and nighttime ambient noise levels. A more detailed noise level sampling procedure was conducted within the Baclaran Church premises. This was done to address the apprehension of church officials that the operation of the LRT will significantly disturb the solemnity of church rites/activities. The average baseline noise level at the Baclaran Church area show an average level of about 62 dB(A) near the Redemptorist Road. The average noise level near the Church side door is 70 dB(A). Biological Aspects Flora There are two (2) major types of vegetation identified in the project area namely the ( i ) natural vegetation types consisting of residual mangroves and grassland; and ( ii ) cultivated vegetation types, which are mainly composed of build-up area ornamental plants. The mangrove plants presently thriving in the project area consist of Aigiceras sp., Bruguiera sp., Excoecaria sp., and Prosopis vidaliana. Field investigation revealed that the area cannot be classified as a mangrove forest since there are relatively few mangrove species in the area, and that the area is deforested. In addition, houses built in the surrounding river systems are observed instead of mangrove species. However, there are indications of a mangrove rehabilitation program as indicated by the presence Page 24 viii of what seems to be a mangrove seedling nursery beside the La Huerta Elementary School. Grasses being referred to her are the common talahib, cogon, makahiya, kulut- kulutan, amorsecos, and carabao grass, among others. Certifications obtained from the respective DENR Offices (attached as Appendix F ) confirmed that there are NO proclaimed protected areas (such as mangrove forests) in the study area. Built-up area vegetation here refers to ornamental plants found around settlement areas, as well as those along roadsides and medians Fauna No in-depth study was conducted for the identification if wildlife fauna (terrestrial) since the alignment will traverse mostly built-up areas. Nevertheless field observation of some common birds and domesticated animals were noted (Please see Chapter 3). Analysis of samples obtained for determining aquatic species from the river systems showed two types of organisms, namely the Pelagics and Benthics. Six (6) species of phytoplankton and three (3) of zooplankton were identified. The nekton observed, and identified are two (2) species of guppy or mosquito fish, which are relatively abundant and dominant. Abundance of this type or organism, plus the deformed morphology of some phytoplankton species are indicators of a polluted habitat. Analysis of Benthos (sandy to blackfish mud) showed no traces of live macro-invertebrates and microorganisms. Resident macrofuana from the mid-littoral zone were not observed either. Not even a single gastropod was observed alive. Socio-Economic Aspects Population Page 25 ix Me tropolitan Manila, the Project’s host Region, is the country’s primary political, economic, social and cultural center, Based on its 1995 population of 9.5 million and an annual growth rated of 3.3% its current population is computed to be 10, 765,115, It is a very crowded area with a population density of 14,800 person per square kilometer. Using 1995 as base year, the NCR population is expected to double in 21 years. The host cities and municipality consists of Parañaque, Las Piñas and the Municipality of Bacoor, in Cavite. Parañaque is one of the more urbanized areas of Metro Manila with a population of 446,145 growing yearly at the rate of 4.6% . As of 1995, Las Piñas recorded a population of 413,086. With an average growth rate of 6.39% , the city will have a populace of 528,011 by year 2000. Like Parañaque and Las PIñas, the municipality of Bacoor is also a catchment area for overspill population from Metro Manila. It currently has a population of 250,821 persons and 52,594 households in its 73 all-urban barangays. Economic Activities For the past 20 years , development in Metro Manila has been towards Parañaque, Las Piñas and Muntinlupa in the south, to Novaliches in the north, and to Marikina Valley in the east. Strongest growth was noted in the northeast (Quezon City) and in the south towards Muntinlupa. The same trends are predicted to continue with growth extending to neighboring town of adjacent provinces. In 1997, registered business and commercial establishments in Par añaque reached a total of 12,818 . Majority ( 53% ) of the establishments belongs to the wholesale and retail sector. Barangay Baclaran remains the main Central Business District (CBD) of Parañaque. Areas along Ninoy Aquino Avenue and A. Santos Avenues ( or Sucat Road ) are emerging commercial and business centers. Page 26 x Industrial firms are concentrated along the South Superhighway. With only 13 hectares devoted to agriculture, activities in this sector are very minimal. Fishing is confined along the coastal areas of Manila Bay. Las Piñas houses mostly small-medium enterprises (SMEs) as most of its big factories have relocated outwards to the CALABARZON area. Ninety percent ( 90%) of its total 10,000 business establishments are SMEs, which are touted as the entrepreneurship base of city’s future role as the “Southgate of Metro Manila” Most of the commercial establishments and large shopping malls are located along the Alabang-Zapote Road. These establishments include Shoemart (SM) South Mall, Manuela Metropolis and Filinvest City. Very little agricultural activity is undertaken in residual farmlands, salt beds and fishponds, which comprise a total of three percent ( 3% ) of the total land area of Las Piñas. Trade, commerce and service sectors constitute the primary sources of income for the Bacoor population. These are mostly wholesale, retail ( sari-sari stores) and restaurant establishments. Business establishments are mostly concentrated in Zapote, Panapaan, Mabolo and Talaba. Other income earners are small-scale manufacturing, cottage industries, and fishing which includes oyster mussel culture. Agriculte experienced a rapid declined due to land conversion for subdivisions. In 1995, registered business establishments reached a total of 3,690 . This number does not include establishments within the Shoemart (SM)-Bacoor Commercial Complex and other commercial buildings that recently sprouted along Aguinaldo Highway. Project Affected Population Groups (PAPG) Page 27 xi Since the Project is only an extension of the existing LRT Line 1, no PAPG shall be significantly affected at the Pasay area. In Parañaque, affected areas are mostly commercial, residential, and institutional. Building owners and the small to medium enterprise occupants, and fixed stall and ambulant vendors comprise the business establishments along Redemptorist Road, Barangay Baclaran. The Baclaran Church compound is also situated along this road, but the church building itself has a set back of approximately 60 meters form the LRT alignment. At a section of the Coastal Road in Barangay Tambo. Big business establishments, including the Uniwide Coastal Mall are part of the impact area. Institutions include the Don Galo Sports Complex, the La Huerta Elementary School, and the La Huerta Barangay Hall. Also included are informal settlers at the north and south banks of Parañaque River (Brgy. Don Galo and La Huerta). In the Las Piñas area, most of the residential/commercial areas to be affected are located in Barangay Pulang Lupa I. They consist of NHA lot awardees/applicants, small house & lot renters, and private residential property owners. Small to medium business establishments include Sarao Motors, Sogo Bldg., automotive shops, a bus terminal and a disco house. Fishpond/saltbed owners and operators / tenants in Abuhan, Brgy. Manuyo I and Irasan, Kawayanan in Pulang Lupa will also be affected. Informal settlers to be displaced include those in Abuhan, Manuyo I and Daang Kariton/Calle 5 Gabriel Compound, Pulang Lupa 1. In Bacoor , Cavite, residential areas, including informal settlers along the east side of the Coastal Road in Barangay Longos/Zapote and a portion of Talaba 2 shall be affected. Commercial establishments such as the AMA Bank along the Talaba Diversion Road will also be affected. Institutions such as the Talaba Elementary School, the Talaba 4 Barangay Hall, Bacoor Police Station and Fire Station, and a Barangay chapel will also be affected by the inevitable widening of the Talaba Diversion Road as part of the engineering design. Page 28 xii Process Documentation Summary Social Preparation Activities As part of the Social Preparation process, Project Briefing Sessions (PBS) were conducted by the Proponent together with the EIA Preparer. These briefings were carried out mainly to (i) inform the Project Affected Persons (PAPs) about the proposed Project; (ii) familiarize them with the EIA process that the project has to undergo, and (iii) hear out their comments, issues, and perception related to the Project. A total of seven (7) formal presentations and briefings were accomplished within the months of April and May. 1999. These consist of PBS with the Provincial Officials of Cavite, City Officials of Pasay, Las Piñas, and Parañaque, and Municipal Officials of Bacoor. Four (4) meeting with various Barangay Officials of the impact areas, and eleven (11) barangay assemblies ( Please refer to the Scoping Report for details). Scoping Sessions 1 st Level Scoping of the Proposed LRT Line 1 Extension Project was held on 22 April 1999 at the EMB Conference Room. Three (3) Formal Scoping Sessions were conducted at different venues, one in Parañaque, one in Las Piñas, and one in Bacoor. All the meetings were well represented and attended by the stakeholders in the project area. After the Open Forum, the Agreed Upon Studies To be Undertaken and Agreed Upon Issues to be Addressed by the EIA were signed by the stakeholders, the Proponent, and the Preparer. Perception Surveys Page 29 xiii Perception surveys of 529 households, 92 business establishments and institutions, and 78 vendors were conducted as part of the preparation of the EIS. IEC/ComRel Campaigns Since the Project will traverse densely populated commercial and residential areas, it is inevitable that negative perceptions are encountered from the initial stages of consultations. To address this, the Proponent thorough its Community Relations Team, launched two programs, namely the Information, Education and Communications (IEC) and Community Relations (ComRel) Campaigns. Several consultations meetings, seminars, and workshops have been conducted with different stakeholders groups (City, Municipal, and Barangay Officials and community members of impact areas, Church leaders, business organizations ) as well as pertinent national government agencies such as the National Anti-Poverty Commission (NAPC), Urban Poor Affairs Office (UPAO) and Presidential Commission on Urban Poor (PCUP), National Housing Authority (NHA), and the Department of Public Works and Highways (DPWH). These were accomplished from August 1999 to January 2000 . Salient points raised during these meetings are included in the EIS as Appendix A. Transcriptions of these are also available upon request. Summary of Proof of Social Acceptability MEASURE OF SOCIAL ACCEPTABILITY · Ecological and Environmental soundness · Effective implementations of public participation process · Promotion of social inter- generational equity and poverty alleviation Page 30 xiv · Resolution of Conflicts On-going Ecological and Environmental Soundness This is addressed by the entire EIS document. Effective Implementation of the Public Participation Process. This was accomplished through a series of project presentations, briefings, seminars, workshops, and consultations meetings with the various stakeholders, from the Pre-Project Scoping stage to the present. (See Scoping Report and Appendix A ). Promotion of Social and Intergenerational Equity and Poverty Alleviation. Skill Training and Resources Mobilization, and Livelihood Training and Development are included as part of the Proponent’s Social Development Program (SDP). This will be part of the Proponent’s effort to provide a mechanism that would weed out undesirable elements that may disrupt the process of social change among the relocatees. Details on the SDP are provided in Chapter 6. Conflict Resolution A draft Memorandum of Agreement ( MOA ) between the Proponent, the MMDA, and the Parañaque Local Government Officials and the affected stakeholders in the Baclaran area is currently being reviewed by the parties involved.

In southern Metro Manila area including the cities of Parañaque, Las Piñas and Muntinlupa has been experiencing rapid urban expansion and attracting primarily residential and industrial development. The increase of infrastructure has been relatively insignificant resulting in reduced levels of service from buses/jeepneys, which currently serve about 70% of the total travel demand in Metro Manila. As well, air pollution is becoming acute due to the traffic situations. These facts have become a serious socio-economic concern to Metro Manila and the surrounding region. The Province of Cavite, which is situated south of Metro Manila, has a high potential for growth, particularly the Municipalities of Bacoor, Imus, and Dasmariñas. Being part of the Calabarzon Region, the province is envisaged by the National Government as one of the seats for special development programs. This is now being realized due to the in-migration, industrialization, and rapid urbanization of the province. With this unprecedented growth, it is now experiencing traffic congestion, which is greatly affecting commuters between Cavite and Metro Manila. The coastal corridor is a vital link to the said southern cities and the Province of Cavite to the center of Metro Manila. At present, the coastal and other transportation corridors in the south of Metro Manila is experiencing heavy traffic congestion that severely affects accessibility to the southern areas, including the Province of Cavite. Current road network improvements and traffic management measures alone cannot alleviate the worsening traffic congestion in the area. To meet the current and future travel demands in the area, a transportation plan must be put in place. This plan should offer an alternative mode of transportation to the present public and private road-based transport modes, in Page 45 3 view of the current traffic congestion. The cornerstone of the transportation plan must be a rail transit network that is integrated with the public and private transportation mode. Furthermore, rail transit is an environmentally friendly mode of transport as it does not contribute to air pollution. The Light Rail Transit Authority (LRTA), an attached agency to the DOTC, will undertake the implementation of the south extension of the existing LRT line 1. The proposed south extension of the existing LRT Line 1 is known as the LRT Line 1 Extension Project. The extension project is envisaged to operate on a fully elevated dual track guideway, from Baclaran, Parañaque City to Bacoor in the Province of Cavite, with a provision for another extension further to the south to Imus and Dasmariñas. 1.2 EIA Approach and Methodology Approach The general approach adopted in the present study is based on the procedural flow of the Environmental Impact Statements (EIS) System prescribed under Article III of the DENR Administrative Order No. 96-37. The EIA Team followed the Participatory Impact Assessment Method (PIAM) wherein the stakeholders were involved in the conduct of the EIA through project briefings, public consultation meetings/barangay assemblies, and formal scoping meeting. Please refer to the Project Scoping Report July 1999 for a discussion of the issues raised and agreed scope of the EIS. Methodology The EIA study covers the following modules: Page 46 4 · Geology · Meteorolgy · Hydrology · Water Quality · Air Quallity and Noise · Terrestrial Biology · Socio-Economics Geology The geological study for the proposed project was done through field verification of existing secondary information. The secondary data used in the preparation of the report were obtained from various concerned offices/entities among others the PHIVOLCS, Mines and Geosciences Bureau (MGB). The R-1 Expressway Project Stage 1, conducted by DCCD Engineering Corporation was also used. Existing literature were also utilized in the preparation of this report. Water Quality Water samples were collected early morning of 19 July 1999 from the rivers and/or creeks that will be crossed by the alignment. Seven (7) sampling stations were identified and selected to establish water quality of the said waterways that may be affected by the proposed project. Field measurements were taken for each sampling station to determine water discharged and temperature readings as well as its pH using a digital pH- meter. Samples were then brought to the SGS Philippines for laboratory analysis of Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), and Oil and Grease content. Air Quality Page 47 5 Baseline air quality sampling for air pollutants such as SOX, NOX and Total Suspended Particulate (TSP) within the vicinity of the proposed project was conducted last 25-26 June 1999. Gaseous pollutants were determined utilizing a Kimoto Gas Bubbler, whereas TSP was measured using High Volume Sampler. The data gathered will serve as the baseline information that will be used for comparison with future levels of air pollutants (during monitoring). Noise Level Noise level samplings were also conducted along the project corridor. The same sampling locations as that of the air quality were used. Noise levels during the morning, daytime, evening, and nighttime were recorded to serve as baseline information that will be used for comparison with future levels of noise. The data gathered will serve as the baseline information that will be used for comparison with future levels of air pollutants and noise levels (during monitoring). Noise Measurement at the Baclaran Church Vicinity Noise levels at the Baclaran Church vicinity were measured during morning, early evening and afternoon period which coincides to the expected AM and PM Peak, and Off-Peak operation of the proposed LRT Extension Project. A One-minute average ambient noise level measurement was conducted using an Extech Sound Level Meter with an A-weighing scale. Noise Prediction at the Baclaran Church Vicinity Page 48 6 Noise modeling comparison the “without project” with the “with project” scenarios was undertaken to determine the effect of noise to be generated by the train operation on the existing noise level. The results of the Sampling obtained last 21 July 1999 within the Baclaran Church compound will serve as input to the said model. The model used for predicting resultant noise levels was by Peters (1974), wherein the prediction of noise from a railway train is due to rail-wheel noise. The assumption is based on a sample linear source as a function of distance from the observer (receptor) to the railway track (source). Peters developed and empirical formula to predict the peak A- weighted sound level where noise is mainly rail-wheel (that are in good condition) and welded track. The formula is normalized to an effective train velocity of 120 kph. The equation is in the form: SPLP = SPLG + 10 log (A/4N) – 20 log (Iv/20) + 25 log (V/120) in dB (A) Where SPLP - predicted sound level pressure SPL - normalized sound level pressure level based on observed –track distance to train length ratio (See Figure 1.1 ) A - mean number of axles of vehicles N - is the number of vehicles Iv - is the vehicle length in meters V - is the train velocity in kph The location of stationary noise source and observer location were considered at ground level. The predicted noise at a distance from the train depends upon the strength of the source and the source- Page 49 7 observer distance at the time the sound is radiated. Effects of barriers and other noise absorption materials were not considered. Barriers and absorption materials have significant reduction in noise source to the noise receptors. Computation of Predicted Noise Levels (generated by the LRT Train) Basic assumption for computing noise generated by LRT -1 Extension are the following: (i) Assumed distances from the train bridge centerline to the observer (receptor points) are 10m, 30m and 60m (ii) Train speed categories for computation are 34-kph and 60-kph, the average commercial speed and maximum operating speed, respectively. (iii) Normalized peak sound level pressure (A-weighted scale) as function of distance shown in Figure 1.1 (iv) Track-observer distance (D) to train length (L) ratio are shown at Figure 1.2 (v) Height of observers is assume to be 1.5 m from the ground (vi) Elevation of the train rail is 5.5 m from the ground (vii) Train length is 106 m ( 26.5 for each coach with 4 coaches) (viii) Noise source is assume at the center of the bridge (ix) Noise observer is opposite (perpendicular) to the railway track Computation of Resultant Noise Levels (Baseline + LRT Train) Page 50 8 Baseline noise level at Baclaran Church area shown an average level of about 62 dB(A) near the Redempptorist Road. The average noise level near the Church side door is about 70 dB(A) . The procedure for combining the predicted noise level due to the LRT-1 Extension project and baseline noise level are as follows: (i) Take the difference between the two noise levels; (ii) Find difference on the nomograph (Figure 1.3) and move horizontally to the left to find the corresponding value on the vertical scale; (iii) Add this number to the larger decibel level. The sum will be the decibel level for the two noise levels. Flora & Fauna Flora Mangrove plants from the selected sampling sites were identified on-site and/or were taken photographs for verification at the laboratory by a plant taxonomy expert. Fauna Terrestrial Fauna Identification of terrestrial fauna present in the project area was based mainly on actual field observation. Aquatic Fauna Page 51 9 Several physicochemical and biological parameters were determined from the Parañaque and Las PIñas Rivers. Surface water temperature was taken with an aide of a laboratory thermometer (China Brand), whereas, salinity was determined using a Baume Hydrometer (China Brand), Light penetration was also conducting a Secchi Disc. Two (2) readings were done to get the average water clarity. Living organisms from the rivers were also identified at the laboratory. The existing nekton was identified on-site and then verified at the laboratory. Plankton samples were collected using plankton net of very fine mesh sized and fixed with Lugol’s solution, composed of Iodine crystals and Potassium Iodide. Samples were then brought to the laboratory for proper identification using a light microscope (Leiz Wetzlar). Photographs were also taken for verification and documentation. Socio-Economic This study is a multi-level socio-economic and cultural investigation of host communities, potentially affected stakeholders and local government units (LGUs) that fall within the route of the proposed project. The objectives of the study are as follows: ¾ To gather baseline data on the socio-economic and cultural situation of the affected communities and stakeholders; ¾ To measure the project’s social acceptability among the various stakeholders; ¾ To identify relevant socio-economic-cultural factors that affect community acceptance; ¾ To gather perceptions of different stakeholder groups about the project especially those pertaining to project impacts; Page 52 10 ¾ To gather pertinent inputs to formulate sociologically and culturally fit mitigating and enhancement measures. This study was preceded by a rigorous scoping process involving several alignment walkthroughs, provincial, city/municipal and barangay consultations. This process facilitated the exact identification of host communities trimming down the original number from 15 to 10 barangays. As the scoping meetings on the barangay level revealed that there is no problem of general community acceptance of the proposed project, the succeeding investigation efforts focused on the identified areas where right-of-way acquisition would take place and on business areas where initial opposition was encountered. This output also includes a review of pertinent secondary sources. Primary data were gathered through the following: ¾ Quick Census & Household socio-economic-cultural and perception survey in identified in affected settlement areas. The survey was done within the proponent- delineated 30-meter corridor from which a final 10- meter right- of-way (ROW) tract would be taken. ¾ Socio-economic and Perception Survey of business establishments, building owners in affected business areas. ¾ Socio-economic and Perception Survey of ambulant and fixed stall vendors. ¾ Perception Survey of affected institutions ¾ Key informant interview ¾ Barangay assemblies ¾ Multisectoral Scoping Meetings Coverage of the Household Census and Sample Surveys are shown in Tables 1.1, 1.2, and 1.3.

Traffic conditions in and around the Metropolis have rapidly worsened, particularly during the 1990s. The increase of infrastructure has been relatively insignificant resulting to reduced levels of service from buses/jeepneys, which currently serve about 70% of the total travel demand in Metro Manila. As well, air pollution is becoming acute due to the traffic situations. These facts have become a serious socio-economic concern to Metro Manila and the surrounding region. The southern area of Metro Manila that include the cities of Parañaque, Las Piñas and Muntinlupa has been experiencing rapid urban expansion and attracting primarily residential and industrial development. It is linked to the rest of Metro Manila by two (2) figure main corridors, the south and coastal corridors. The Province of Cavite is situated south of Metro Manila. Due to its proximity to Metro Manila, Cavite has a high potential for growth, particularly the Munucipalities of Bacoor, Imus, and Dasmariñas. Being part of the Calabarzon Region, the province is envisaged by the National Government as on the seats for special development programs. This is now being realized due to the in- migration, industrialization, and rapid urbanization of the province. With this unprecedented growth, it is now experiencing traffic congestion, which is greatly affecting commuters between Cavite and Metro Manila. Page 60 18 The Need The Coastal Corridor ( Figure 2.1 ), from Baclaran to Zapote is one of the highest growth areas of Metro Manila. Situated along the coast of south Metro Manila, the corridor is a Vital link to the southern cities and munic ipalities, connecting Parañaque, Las Piñas, Muntinlupa, and the Province of Cavite to the center of Metro Manila. Currently, the coastal and the other transportation corridors in the south of Metro Manila is experiencing heavy traffic congestion that severely affects accessibility to the southern areas, including the Province of Cavite. Not to mention the fact that the road network in the corner of Bacoor is nearing gridlock, including Gen. Emilio Aguinaldo Highway, the Las Piñas-Talaba Diversion Road, and the Real Street. Road network improvements and traffic management measures alone cannot alleviate the worsening traffic congestion in the area. To sustain continued growth and avoid economic stagnation, and to meet the current and future travel demands in the area, a transportation plan must be put in place. This plan should offer an alternative mode of transportation to the present public and private road-based transport modes, in view of the current traffic congestion. As such, the cornerstone of the transportation plan must be a rail transit network that is integrated with the public and private transportation modes. Furthermore, rail transit is an environmentally friendly mode of transport, as it does not contribute to air pollution. At present, the Department of Transportation and Communication (DOTC) is preparing a “transportation master plan” ( See Figure 2.2 ) through the ongoing Metro Manila Urban Transportation Integration Study (MMUTIS). In the recent status report of MMUTIS, it was revealed that the South Extension of the existing LRT Line 1 to the Province of Cavite is indeed a priority. Page 61 19 An analysis of the distribution of transport demand was conducted using the 1996 MMUTIS origin- destination for public and private modes (excluding walking trips). The distribution of transport demand is indicated by the desire lines of travel. Trips are concentrated in the core area of Metro Manila generally bounded by EDSA Avenue. Also trips, of the suburban area outside EDSA are heavily focused toward this core area of Metro Manila A high desire line is between south Metro Manila and Metro Manila to the north that has 1.3 million daily trips. There are a total of 2.0 million daily trips across a screen line along a boundary between south Metro Manila and the remainder of Metro Manila. These 2.0 million daily trips are funneled through the coastal and South Super Highway/PNR corridors. South Metro Manila produces and attracts a total of 3.1 million daily trips. Of this total, 1.4 million trips ( 45% ) are internal trips with origin and destination within south Metro Manila, and the remaining 1.7 million daily trips ( 55% ) have their origin or destination outside of south Metro Manila. It is in this vein that the LRT 1 Extension Project was conceptualized and designed to provide easy access to the burgeoning populace of south Metro Manila. The Light Rail Transit Authority (LRTA), an attached agency to the DOTC, will undertake the implementation of the south extension of the existing LRT Line 1. The proposed south extension of the existing LRT Line 1 is known as the LRT Line 1 Extension Project . The extension project is envisaged to operate on a fully elevated dual track guideway, from Baclaran, Parañaque City to Bacoor in the Province of Cavite, with a provision of another extension further to the south to Imus and Dasmariñas. Page 62 20 2.2 Alternative Routes Alternative routes were studied to minimize the potential adverse impacts on the environment, while enhancing the level of service to the traveling public and constructing a cost-effective system. In order to add an element of flexibility in the selection process, the routes were divided into the North and Central Sections at the Parañaque River. And since the study areas are highly urbanized, the development of the route alternatives was primarily influenced by the existing development constraints. Thus, route opportunities were limited along the right-of-way reclamation land, other vacant lands, river banks, and marine ponds/salt beds. 2.2.1 The Five (5) Basic Alternative Routes As previously mentioned, the alternative routes studied were divided into the North and Central Sections at the Parañaque River. Discussed below are the five (5) basic alternative routes studied. Figure 2.3. Land Reclamation-Manila Bay Route (Alternatives 1N & 1C) This route will run west from the Redemptorist Road onto the land reclamation and then turn south to run along the main spine road of the Boulevard 2000 development. It will continue to run south on the reclamation land through the planned Boulevard 2000 and Asia World developments to the end of the reclamation at the mouth of the Parañaque River. The land reclamation project of Public Estates Authority (PEA) is planned to be extended further south from the ASIA World development the Cavite foreshore (Manila Bay). The route will continue along this future land reclamation area to the Cavite foreshore, where it will deflect south to join with Aguinaldo Highway. The implementation of this section is dependent on the completion of the land reclamation by PEA. Page 63 21 Roxas Boulevard-Coastal Road Route (Alternatives 2N & 2C) This route, from Redemptorist Road will run south along the center median of Roxas Blvd. Alternatively, the line could run along the west side of the road, either within or adjacent to the right-of-way, which is currently undeveloped. An alignment along the east side of Roxas Boulevard was rejected as it would be too close to the existing frontage development. The line would be elevated for its entire length, as there will be many future roads crossing the line when the road network of Boulevard 2000 development is completed. As the alignment approaches the mouth of Parañaque River, it will cross to the east side of the Coastal Road, where the existing development is sufficiently set Back from the right-of-way. It will follow the east side of the Coastal Road within the right-of-way onto Cavite. The southern terminal station will be located in the Municipality of Bacoor near Aguinaldo Highway. Quirino Avenue Route (Alternatives 3N & 3C) This route will run south along Quirino Ave. on an elevated guideway from Redemptorist Road to Aguinaldo Highway in the Municipality of Bacoor. Quirino Ave. is a narrow two-lane road for most of its length, and has frontage developments along both sides with minimal set back. The alignment will run along the center of the said avenue. At the north end, it will directly connect to the existing LRT line 1 at Baclaran Station. The stations will be elevated over the road, with platforms and stairway access extending beyond the right-of-way in some locations. Page 64 22 Parañaque River-Las Piñas/Parañaque Commercial Zone Route (Alternatives 4N & 4C) This river route will run south from Baclaran Station of LRT Line 1 along the west bank of Parañaque River. At the north end, a new north terminal station will be introduced near Baclaran Station. From the north terminal station, the route will run south along Bac-II Road. It will continue south along the east bank of Parañaque River to the confluence of Parañaque and Las Piñas Rivers. The route will continue south along the east side of Las Piñas River through an open area of marine ponds and salt beds, which is designated for future commercial development. It will then veer to a westerly direction and run along the bank of Las Piñas River, crossing over Tramo Road and Quirino Avenue. The line will then curve south the through the open area on the east side of Coastal Road. Ninoy Aquino Avenue-Tramo Road Route (Alternatives 5N & 5C) This route will run south along the west side of Roxas Boulevard to the Airport Road. At the Airport Road, it will turn east along the center of the road and then deflects to a southerly direction to follow along the west side of Airport Avenue. The line will head towards Ninoy Aquino Avenue by running along the center median of MIA Road. Along Ninoy Aquino Avenue, the alignment will traverse along the center median and cross to the west side of the road to avoid the elevated access road to NAIA Terminal I. Past the elevated access road, the route will cross back to the center median and continue south to the Parañaque River. The alignment will continue south from Parañaque River along the center of Ninoy Aquino Avenue to Dr. Santos Avenue. Near the said avenue, it will head towards Tramo Road via A. Bonifacio Road. The route will then continue south on Tramo Road to Alabang-Zapote Road. Beyond Alabang-Zapote Road, the alignment will run west through existing development to reach Quirino Avenue. Page 65 23 2.2.2 The Four Short-Listed Alternatives Routes 2.2.2.1 Routing Combinations In developing the route alternatives, it became apparent that a degree of flexibility could be achieved by utilizing the combinations of North and central segments of adjacent corridors that lent themselves well to “crossover” configurations. The prospective combinations are listed below and are shown on Figure 2.4 . · IN Land Reclamation - 2C Coastal Road Routes; · 2N Roxas Boulevard - 4C Las Piñas / Parañaque Commercial Zone; and · 5N Ninoy Aquino Avenue - 4C Las Piñas / Parañaque Commercial Zone. 2.2.2.2 Route Evaluation Criteria The criteria for evaluating the candidate routes were developed in relation to the following project objectives: (i) to provide a rail-based mass transit link to the existing LRT Line 1 terminus at Baclaran in Pasay City and Zapote in the Province of Cavite, which can be integrated with the planned mass a transit network and surface modes of public transport as a means of meeting established economic growth targets; (ii) to optimize the level of service to the traveling public in the target corridor by providing a transportation system that is convenient, accessible, fast , reliable, and safe; Page 66 24 (iii) to avoid, minimize or mitigate potential adverse environmental effects and achieve sustainable environmetal conditions to the greatest degree possible; (iv) To satisfy the LRTA’s functional and design requirements for the provision of rail-based mass transit services; and (v) to optimize the return of investment through construction of a cost-effective system. The criteria applied on evaluation process of the extension route was primarily based on seven (7) major factor groups, which are briefly discussed in Table 2.1.

Page 68 26 2.2.2.3 Route Evaluation and Selection Evaluation Process A joint evaluation process was undertaken to select a technically preferred route for the proposed LRT Line 1 Extension. It was participated in by LRTA, the Cities of Parañaque and Las Piñas, and the Municipality of Bacoor and the province of Cavite. The Study Team performed an initial route assessment and comparison and presented the results to the LRTA, and the Cities of Parañaque and Las Piñas, and the Municipality of Bacoor for their inputs and comments. The route assessment was then revised to reflect the comments received and obtain a consensus on a technically preferred route. Stage 1 – Initial Screening of Route Alternatives The Feasibility Study Team performed an initial route assessment and comparison to eliminate route alternatives that were rated the poorest in terms of achieving project objectives. The initial screening process entailed a qualitative assessment of the routes, which is based on the seven (7) primary factor groups defined in the evaluation criteria presented on Table 2.1 . During the qualitative assessment, the Study Team concluded that five of the ten (10) route segments should be discarded, and that combinations of the remaining five (5) segments should be carried forward for a more detailed assessment. The screening results are presented on Table 2.2 . Page 69 27 Table 2.2 Summary of Rationale for Routes Screened Out Route Section Route Segment Rationale for Screening Quirino Ave. (3N) ƒ limited space for intermodal facilities; ƒ narrow right –of-way results in taking of traffic lane in an area already subject to heavy traffic congestion; ƒ displacement of residences; ƒ displacement of existing businesses and commercial premises; and ƒ costly relocation of utilities North Section Parañaque River (4N) ƒ limited access to buses and jeepneys; ƒ very limited spaces for intermodal facilities; ƒ displacement of residences along river bank; and ƒ proximity effects (noise/visual). Central Section Manila Bay (1C) · high risk, in terms of ridership, associated with dependence on future land reclamation (uncertain time frame), combined with indirect route to the candidate southern terminus locations in Cavite; · costly construction over water if the project proceeds without land reclamation; and · very limited accessibility to Las Piñas and Parañaque. Central Section Quirino Avenue (3C) · limited space for intermodal facilities; · narrow right-of-way results in taking of traffic lane in an area already subject to heavy traffic congestion; · proximity effects (noise/visual); · displacement of residences; · displacement of existing businesses and commercial premises; · impacts to historical corridor and designated tourism zone; and Page 70 28 The Quirino Avenue Route was screened out over its whole length primarily due to the property requirements and environmental impacts associated with attempting to fit the alignment into such a narrow right-of-way. In addition to the land requirements for the stations, the guideway would require the addition of new traffic lanes which could displace homes and businesses abutting the street. The potential for noise and visual impacts of the elevated guideway, particularly on the southern segment of the route which is a designated historical corridor and tourism zone, was also a significant determining factor in discarding this option. The key factors for eliminating the Parañaque River Segment was its poor service in comparison to the Ninoy Aquino Avenue and Quirino Avenue segments. The segment is difficult to access due to its location along the Parañaque River and there is a limited space for intermodal facilities. In addition, there is relatively dense residential development, including legal homes, squatter settlements, and important community/institutional buildings that would be displaced or be subject to significant visual and noise intrusion. The essential factors for eliminating the Manila Bay Segment were poor service coverage and high cost which can be attributed to the timing of the land reclamation project. Since the land reclamation area is currently undeveloped, this route is not likely to capture enough ridership to make it financially viable. Furthermore, the land reclamation currently ends at the mouth of the Parañaque River. Beyond the southern end of the land reclamation, the guideway construction would be more costly, as it would be constructed over water or require further land reclamation. The Tramo Road Segment exhibits land use and right-of-way characteristics similar to those of the Quirino Avenue corridor and the same rationale was used to screen it out. Page 71 29 And based on the initial evaluation screening exercise, the Team arrived at the four (4) route combinations that would be carried forward in the detailed route evaluation process. The four (4) route combinations are enumerated below and are attached as Figure 2.5 . ƒ 1N Land Reclamation - 2C Coastal Road Route; ƒ 2N Roxas Boulevard - 2C Coastal Road Route; ƒ 2N Roxas Boulevard - 4C LP Commercial Zone; and ƒ 5N Ninoy Aquino Avenue - 4C LP Commercial Zone With the four (4) routing combinations presented above, the Feasibility Study Team came up with the four (4) short-listed route alternatives, which is shown on Figure 2.6 . Stage 2 – Detailed Route Evaluation The four (4) short-listed route alternatives were subjected to a detailed impact analysis applying all the seven (7) evaluation criteria listed on Table 2.1. The team conducted a preliminary evaluation and rating of the alternatives to identify the key issues and determinant factors in accordance with, and to confirm the initial weighing of the criteria. The results of this process were presented to the LRTA, the Cities of Parañaque and Las Piñas , and the Municipality of Bacoor for review and comments. The evaluation was then revised to incorporate comments and inputs from the LRTA, and concerned LGUs. Step I Weighting of Evaluation Criteria – Since the criteria and factors were not deemed to be of equal significance by the Study Team, initial weightings were assigned to each criterion and factor, giving more weight to what were determined to be the more important considerations in the decision making process. Page 72 30 Step II Analysis of Route Alternatives – A detailed analysis of each route alternative was conducted on a factor-by-factor basis to measure how well each alternative met the project alternatives. The analysis formed the information database on which to conduct the comparative evaluation. Step III Rating of Route Alternatives – based on the results of Step II, a qualitative rating was assigned to each route alternative on a factor-by-factor basis to determine how well each alternative route satisfied the project objectives. Step IV Selection of Technically Preferred Route – From the rating established in Step III, the key differences between the route alternatives were identified; this became the focus of discussion with the LRTA and the Cities of Parañaque and Las Piñas, and the Municipality of Bacoor to reach a consensus on a technically preferred route. Step I Weighting of Evaluation Criteria The first step involved assignments of weight to the evaluation criteria and factors by the Study Team. Weights were assigned to the criteria and factors on a scale of 1-10 , where a more important criterion and factor was assigned a higher weight, (Table 2.3) . It should be noted that the criteria and factors were assigned numerical weightings to assist the Team in developing a rational thought process. The weightings are only indicative of the importance attached to each criterion and factor, and did not form the basis for a quantitative rating of the route alternatives.

Feasibility Study for the Manila LRT Line 1 Extension, Volume 2 Page 74 32 Step II Analysis of Route Alternatives A detailed analysis of the four short-listed alternatives was conducted by qualitatively and quantitatively measuring how well each route satisfied the project objectives. The analytical information was summarized in evaluation tables containing an assessment on each route alternative for each evaluation factor. The results were then presented to the LRTA, to the C ities of Parañaque and Las Piñas, and the Municipality of Bacoor for review and comment to ensure that the analysis was based on up-to-date and complete information. The analysis information provided the basis for subjectively assigning scores to the route alternatives. Table 2.4 Summary of Detailed Assessment of Short- Listed Route Alternatives summarizes the analysis of the route alternatives. Step III Rating of Route Alternatives Based on the analysis information, a comparative evaluation of the route alternatives was conducted by assigning ratings to each option on a factor-to- factor basis. The criteria and factor weightings were considered qualitatively in the final determination of the technically preferred route. Figure 2.7 shows the ratings of the Study Team which were subsequently adjusted, where required, to reflect input and comments received from the LRTA, the Cities of Parañaque and Las Piñas, and the Municipality of Bacoor. In summary, over the full range of evaluation criteria, the Land Reclamation- Coastal Road Route, the Roxas Boulevard-Coastal Road Route, and the Roxas Boulevard –LP Commercial Zone Route were rated most equal (within 10% of each other). Whereas the Ninoy Aquino Avenue-LP Route was deemed to be measurably less desirable than the other three (3) options. Page 75 33 2.2.3 Selection of Technically Preferred route for North and Central Sections In the selection of a technically preferred route, the Study Team considered the following most heavily weighted evaluation criteria to determine the most acceptable alternative; i) Service Coverage; ii) Accessibility to buses and jeepneys; iii) Support for future land use development; and iv) Environmental impacts. 2.2.3.1 Assessment of Key Evaluation Criteria Figure 2.8 - Assessment Summary of Key Criteria , isolates the rating of the key evaluation criteria. In light of these considerations, the route alternatives were ranked as follows: Roxas Boulevard-LP Commercial Zone Route was ranked first overall. Its key advantages include: ƒ Fair service coverage to mature development on the east side of Roxas Boulevard corridor and good coverage for existing residential areas in Parañaque and Las Piñas; ƒ Good bus and jeepney accessibility at regular intervals along the route via Multinational Drive, Dr. Santos Drive, Quirino Avenue, Naga Road, Alabang-Zapote Road, and Gen. Aguinaldo Highway; ƒ Route along Roxas Boulevard will support Boulevard 2000 development. The central section of the route will support the proposed commercial and industrial areas in Parañaque and Las Piñas; and Page 76 34 ƒ No identified cultural resource impacts; opportunity to avoid or mitigate proximity effects (noise, visual intrusion) through sensitive guideway/station design in new developments (integration with spine roads). Coastal Road-Roxas Boulevard Route – This alternative was ranked second overall. This option provides fair service coverage in the North Section, but there is no frontage development on the Coastal Road, and residential catchment areas to the east are removed from the corridor. This route has poor accessibility for buses and jeepneys, as there are few roads to the coast (Kabihasnan Drive, Alabang-Zapote road, Gen. Aguinaldo Highway). The potential for adverse environmental impacts is low and the route would be the least costly option due to the directness of routing and the limited need for acquisition of private property. Ninoy Aquino-LP Commercial Zone was ranked third overall. This alternative provides fair to good service to existing industrial and commercial areas in the Ninoy Aquino Avenue corridors and offers the most direct link to the Ninoy Aquino International Airport (NAIA). It would also serve existing residential areas in Parañaque and Las Piñas. However, it is the least direct route between the north and south terminal areas. This, combined with the need to acquire a substantial amount of private property, makes it the most costly route. The route has good road linkages for bus and jeepney access due to existing network serving NAIA and surrounding development. Although the route would not directly support Boulevard 2000, it would run through the proposed industrial areas in Parañaque and Las Piñas. In terms of environmental impacts, the route runs through a corridor which is currently subjected to high noise level as a result of its proximity to NAIA, and has no identified cultural sensitivities in the North Section. In the South Section, its exhibits the same potential for avoidance of proximity effects as the Roxas Page 77 35 Boulevard-LP Commercial Zone option, and has the highest number of water course crossings. The Land Reclamation-Coastal Road was ranked fourth overall. The attributes of this route are similar to those of the Coastal Road-Roxas Boulevard Route, with the exception of rapid transit service. Since the reclamation land is currently undeveloped with substantive plans in place, it has poorer service coverage, a lower degree of accessibility and less capability to satisfy ridership demand. 2.2.3.2 Route Selection The results of the comparative evaluation were reviewed by the LRTA and the City representatives from Parañaque and Las Piñas. A technically preferred route was selected, following discussions of the key advantages and disadvantages of the routes, focusing on the determinant evaluation criteria. It was agreed that, at a technical level, the Roxas Boulevard-Las Piñas/Parañaque Commercial Zone route is the preferred alternative (Figure 2.9) . It provides the most comprehensive service coverage, exhibits optimal accessibility and good opportunities for integrating existing transit services, and creates a reasonable balance between environmental impacts and capital costs. 2.3 Project Area and Location The project will pass through three (3) cities in Metro Manila namely; (i) Pasay; (ii) Parañaque; and (iii) Las Piñas, and the Municipality of Bacoor in the Province of Cavite. Page 78 36 In Pasay City, the proposed railway extension will traverse Barangay 145 (Sto. Niño). In the City of Parañaque, the alignment will cross five (5) barangays namely Baclaran, Tambo, Dongalo, San Dionisio, and La Huerta. In Las Piñas City, the Extension Line will pass through barangays Manuyo Uno and Pulang Lupa, whereas in Bacoor, it will cross Brgys. Longos/Zapote 5, Talaba 2, Talaba 3, Talaba 4, and Talaba 7. The LRT Line 1 Extension The proposed LRT Line 1 Extension Project will be directly connected to the Baclaran Station of the existing LRT Line 1, and will be using the present LRT Depot in Pasay City. From the Baclaran Station, the proposed Extension alignment will turn west at Redemptorist Road, traversing the southern side of the road towards Roxas Boulevard. The alignment then turns south, passing through the reclaimed area on the western portion of Roxas Boulevard, about 6.5 meters from the sea wall. The Extension will have its first station (Redemptorist Station),at Brgy. Baclaran, Parañaque City approximately at km 0+650-0+750. The alignment will continue to traverse the reclaimed area, crossing MIA Road (MIA Station at km 2+250-2+350 ), then pass through the parking lot in front of Uniwide Coastal Mall. It will maintain its course until it reaches the Asia World (Sta. 3, Asia World Station approximately at km 3+050-3+150 ), where it deflects on an easterly direction following the course of the Parañaque River. The proposed Extension Line will use the middle of the said river to avoid concrete structures and shanties on both sides. Still running on easterly direction, the alignment will continue traverse the river, crossing the Quirino and Ninoy Aquino Avenue Bridges, and then veers southwest at the river bend in Brgy. La Huerta, Parañaque City, to merge with Ninoy Aquino Avenue. Using the median of the avenue, it will continue to follow its course until it reaches the San Dionisio River, at Brgy. San Dionisio, Parañaque City (boundary of Ninoy Aquino Ave. and Dr. Santos Avenue). At about 100 meters after the bridge, it will then shift to a southwesterly direction crossing the proposed C-5 Highway alignment Page 79 37 (crossing Dr. Santos Ave.) and head towards the next station, located approximately 150 meters (Dr. Santos Station and Intermodal Facility) from the avenue. This are acrossed by the alignment is the site of the proposed Multinational Development. The proposed Line 1 Extension will move onto the landfill area, salt bed and fishponds in Manuyo Uno, Las Piñas City, where the future Manuyo Uno Station will be constructed (approximately at km 7+050- 7+150 ). It will continue on a southwesterly direction towards the Golden Haven Cemetery and the built-up areas along Tramo Road near the bridge, at Pulang Lupa1. The alignment will directly pass through the houses near the bridge, then cross Quirino Avenue, and then traverse the southern bank of Las Piñas River, where the Las Piñas Station will be located. Still on the same direction, the alignment continues, traversing some fishponds at Pulang Lupa 1 near Zapote River, then cross the river and head towards the proposed Zapote Station and its intermodal facility approximately 250 meters before the Talaba-Diversion Road. The alignment continues southwest and cross under the Coastal Road Flyover. It will then deflects south traversing Brgys. Talaba 7 and 2 (future Talaba Station, km 10+850-10+950 ), and will then merge with the existing Talaba Diversion Road, approximately 100 meters from its intersection with Real Street. The Extension continues south, traversing the center of the Talaba Diversion Road, then cross the junction of the Talaba Diversion Road and Gen. E Aguinaldo Highway, then leaves the existing diversion road and head towards the Niog Station. The first phase of proposed extension will end near the St. Dominic Hospital where the Niog Station and the intermodal facility will be located. (See Figure 2.10). The proposed LRT Line 1 Extension Project is a 12-kilometer light rail system that will operate on a mostly elevated dual track guideway from Baclaran, Parañaque City to Bacoor in the Province of Cavite. It will utilize a technology that is compatible with that of the existing LRT Line 1 and its 100% capacity expansion. The Project, consisting of ten (10) passenger stations and a satellite depot will serve the southern area of Metro Manila and the northeast corner of Page 80 38 the Province of Cavite. It will also include three (3) intermodal facilities, which will be provided at Dr. Santos, Zapote , and Niog Stations. The LRT Line 1 Extension is an integrated system optimizing patron convenience, operational efficiency, cost economy and modal interface/network connectivity. Its key features include the following: ƒ Consistency with the rail transit network plan prepared by the Metro Manila urban Transport Integration System (MMUTIS); ƒ Interconnectivity to the existing Line 1 at Baclaran Station, to form a continuous line and transport more people; ƒ Technology compatible with the existing Line to permit through running of trains; ƒ Integrated fare collection system, with ticket commonality for seamless travel with LRT Line 1, LRT Line 2, and the Extension; ƒ Intermodal facilities at three major stations; and ƒ Single operating authority for the operations and maintenance of the System. 2.4 Project Description This section discusses the activities involved during the Pre-Construction, Construction, Operational, and Abandonment (Demobilization and Maintenance) Phase of the proposed LRT Line 1 Extension Project. 2.4.1 System Overview 2.4.1.1 System Demand and Capacity The peak-hour maximum link load is estimated to be 15,500 passengers per hour per direction (pphpd) in Year 2005. This Page 81 39 maximum load point occurs between Redemptorist and Baclaran Stations, in the northbound direction during the morning peak hour. The system will be designed for an initial system capacity of 15,500 pphpd to meet the estimated demand with provision to expand its capacity to 30,000 pphpd with additional rolling stock. The initial fleet will have a total of forty-four (44) vehicles, configured into eleven (11) four-vehicle trains , which are composed of ten (10) operational trains and one (1) spare train. 2.4.1.2 System Performance and Operation The LRT Line 1 Extension will provide service 17.5 hours per day for 365 days per year. The operating hours will be from 0500-2230 hours to match the current operating hours of LRT Line 1. Simulations of train performance on the route, including station dwell times of thirty (30) seconds, indicate a round trip time of forty-two (42) minutes on the Extension. The maximum operating speed will be sixty (60) kilometers per hour and the average operating speed including dwell time at the stations will be thirty-four (34) kilometers per hour. The full operational fleet will be put into service during the morning and afternoon peak periods of demand. During off-peak periods, the service will be determined by the demand. 2.4.1.3 Alignment Configuration Geometric Design and Criteria The horizontal and vertical alignment has been designed to suit the proposed light rail vehicle technology and to conform with the geometric Page 82 40 design criteria of the existing LRT Line 1 to ensure compatibility with the existing technology. Alignment restrictions including curve radii, superelevation on curves, minimum tangent lengths between curves, spiral lengths and grades have been established as a minimum or maximum to ensure passenger comfort. The alignment has been designed to optimize the following requirements: ƒ Maximum comfort and safety for passengers; ƒ Maximum systems safety; ƒ Compatibility with the characteristics of the existing rolling stock; and ƒ Minimum track and rolling stock maintenance. The basic design criteria established for the horizontal and vertical alignment of the track are as follows: Maximum operating speed 60 km/h Horizontal curve radius 250 meter desirable on mainline 170 meter minimum on mainline except near stations 100 meter minimum on mainline in vicinity of stations 30 meters minimum in depot Transition spirals 40 meter desirable 35 minimum Tangent between curves 50 meter minimum on mainline Grade 0.5% minimum 3.5% maximum Page 83 41 0.00to 0.5% in stations Vertical curves Parabolic K=10m Vertical clearance 5.0 meters between catenary and high voltage power lines 5.5 meters over road 2.4.1.4 Guideway Structure Design Criteria and Loads A project Design Manual setting out governing design codes, criteria and parameters will be generated for the systems elements including the Civil/Structural components of the Guideway. The design manual will be based on the major elements presented in Table 2.5 , and will be similar to other manuals developed for other such projects.

Guideway Beam The following structural options were considered for the LRT Line 1 Extension’s guideway beam: ƒ Dual trapezoidal Box Beam Elevated Guideway – The Guideway beam in this concept as shown on Figure 2.11 are trapezoidal box beams with approximately 3000 mm wide to flange, which acts a sinlge guideway/trackway slab. The typical guideway is comprised of a dual pair of guideway beams configured in parallel. A complete beam span is fabricated in the Precast yard with precision setting of track fastener plinths suitable for direct fixation. Beams are formed in articulated forms which can accommodate the vertical, horizontal and superelevated geometry of the trackwork. Experience with this system indicates that the beams can be erected and the track directly fastened with minor amounts of shimming or grinding. The Superior torsional stiffness of the trapezoid box lends itself to use in curved and superelevated geometry and provides the stability for use of erection trusses and travelers. ƒ Dual Trapezoidal “Two Component” Box Beams – The Guideway beams in this concept as presented on Figure 2.12 are identical in general arrangement to the proposed “Single Component” beams, but are constructed in two (2) stages. First, the precast “Tub” component is erected onto the columns, and then Page 87 45 the precast top flange “Plank” components are erected in segments on top of the “Tub”. This approach allows precision setting in place of the top plank to track grades for direct fixation without the need for any shimming or grinding at the track fastener plinths. Concurrent precasting of the “Tub” and “Plank” components provides schedule advantage during the precasting process and beam transportation and erection process. Since this project is schedule driven, this option will be pursued further as the primary recommendation to achieve a cost/benefit solution. ƒ Single Segmental Trapezoidal Box Beams – This construction method is commonly used for elevated guideways and is a well understood technology for use in beam fabrication and erection. If this concept were to be used, a second pour would be required to provide the track slab. For this project with this concept, LRTA would propose to use precast “second pour” slabs similar to that developed by them for the recently completed Kuala Lumpur LRT System. This concept was not selected primarily because, segmental beam erection f ollowed by a fabrication and erection of precast track slabs will cause an unacceptable extension of the project schedule. Please refer to Figure 2.13 for the general arrangement of guideway scheme in this concept. ƒ Multiple ASSHTO Beam and Slabs – This construction method is similar to the existing LRT Line 1 System, which consists of standard prestressed concrete girder with a cast-in-place guideway slab. This option will require the use of a second pour for the superelavation and track geometry which will add time and cost to the guideway construction. Since this technology is well understood and has been used locally, it may have some cost advantages for Page 88 46 the guideway construction. It is also probable that the added costs of the second pour will eliminate the guideway cost construction cost advantage. LRTA has also determined that this approach will likely require a longer schedule than the selected option. This concept was therefore not selected primarily due to the schedule extension. The general guideway scheme in this concept is presented on Figure 2.14. The Proposed Guideway General Arrangement The guideway of the Extension will be mostly elevated with transitions to grade Dr. Santos Station and Zapote Station. The structural system proposed for the standard guideway consists primarily of the following: Dual pre-cast/pre-stressed or post-tensioned concrete trapezoidal box beams one for each trackway. Spans typically planned on an average length of 30 meters , except in stations where they are planned to be 20 meters; Cast-in- place concrete “Hammerhead” piers consisting of a cross head supporting both box beams supported in turn by a single column located at the centerline of Dual Guideway; and Piled foundations consisting of pile groups with pile caps set below grades. The entire guideway has been framed based on the selected structural system, and the preliminary alignment and mapping using nominal 30-meter tangent span length. Substructures have been arranged to minimize conflicts with all identified utilities, properties, and other physical constraints. Where required, substructures have been arranged to reduce span lengths on tight radius curves to accommodate torsional constraints of the beam. The general arrangement of the proposed guideway scheme is presented on Figure 2.15. Page 89 47 The dual guideway provides two (2) parallel tracks at 4300 mm on center. This plan arrangement remains for the entire system, except at center platform stations and pocket tracks. Where the center track distance varies, the dual guideway will transition to two (2) single guideways supported on individual columns. Pocket tracks will employ support bents which will support the guideway and pocket tracks as required. Stations will be framed integrally with the guideway structure based on a 20-meter span. The proposed guideway beam consists of a trapezoidal box element spanning, as a simple span, nominally 30 meters between the substructure supports. In stations, the guideway beam will span 20 meters to fit with the station module. The guideway beam has a 3000-mm wide top flange providing a 2910-mm wide trackway slab between parapets. Each guideway beam will be cast with the horizontal and vertical geometry as well as superelevation to provide for direct fixation tracks on plinths on the beam’s top flange. The plinth will be configured to provide sufficient separation between the rail and storm water collected on the guideway while at the same time providing a direct fixation surface within the track placement tolerances. This plinth can be constructed as part of the pre-cast beam fabrication or after beam erection as a second pour. Wherever possible, the guideway will be constructed using the simple span beams. If required, the system can be configured into two-span , three-span , and multi-span continuous general arrangements. The two-span arrangement allows for two 36-meter spans; the three-span enables a 36/45/36-meter span arrangement. Arrangements with multiple 45-meter spans can be generated within the constraints of a track and structure expansion/contraction interaction. The potential use of continuous arrangements provides flexibility to accommodate a wide variety of conditions with varying span ranges without Page 90 48 having to introduce other “special” structures with deeper cross-sections or using other materials such as steel box girders. The substructures for the dual guideway are proposed to consist of “hammerhead” cross heads supported on a single column extending down to the foundation below grade. For the dual guideway, the cross head is proposed to be configured to fit with the depth of beam dap to provide a continuous flat soffit. Columns will vary in size from 1400 mm square to 1900 mm square depending on height. Round columns may also be considered based on the economies of formwork and materials of construction. Substructures for single guideways consist of a cross head and column with the cross head configured to fit within the beam dap and width. The substructures used at the stations and in special trackwork areas consist for the most part of rigid cast-in-place concrete bents. The simple span beams will bear on elastomeric bearing pads, which allow controlled lateral, transverse and rotational movements. At continuous span cross heads, the beam and cross head will be integral. The use of an elastomeric bearing pad introduces a base isolation effect which can reduce seismic response forces in the substructures and foundations. As well, this type of bearing as allows load distribution to varying height columns to be equalized by “tuning” the total pier stiffness. The vertical geometry will facilitate guideway drainage along the beam to the drains at each substructure element. Drains will run down the columns and wherever possible, be tied into the storm drainage systems which are currently carrying the run off within the guideway footprint. Special Structures Page 91 49 A number of areas have been identified which will require spans longer that the typical 30-meter span planned for this project. Where special span arrangements are required, the proposed beam cross section will be configured into continuous two (2), three (3), and multi-span arrangements to extend span lengths to 80 meters in tangent sections. Table2.6 describes the special structures identified, their location, description and the proposed span arrangement to avoid conflicts.

Manila LRT Line 1 Extension Offer for Implementation and Operation, Volume II Implementation & Technical Plan Page 92 50 Tie –In to the Existing Structure The tail tracks at the southern end of the existing LRT Line 1 terminate at Mexico and Redemptorist Roads. The alignment of the Extension will tie into the existing line before the end of the tail tracks and will immediately curve to the west to run along Redemptorist Road. To allow for this curve, the last two (2) spans will need to be reconfigured as shown on the attached Figure 2.16. The structural framing proposed consists of constructing new bents and corresponding foundations at the last two (2) column lines of the existing guideway. This bents will tie into the existing columns and extend over Mexico Road to new columns in the intersection median island. New tee beams with varying top flange width will be placed to provide the track bed for the new curve. The existing tee beam on the west side of the second last span will be modified to allow installation of a new tapered beam to expand the deck. A transition slab, which allows a stepped variation in ballast depth, will be installed within this last two modified spans to provide the track transition to direct fixation. The southern most bent will provide fort he first span of the standard dual guideway of the proposed LRT Line 1 Extension. 2.4.1.5 Passenger Stations Station Types The stations will be either side or center platforms.

They will meet the requirements of the Philippine Building Code and NFPA 130. Public Spaces Design Parameters The design of public spaces follows the international design practices for contemporary transit stations as reflected on the station floor plans. Stations may be unique depending on their urban settings, but will have common elements that will be consistent system wide. Commonality will be achieved by function, space and form, lighting, signage and equipment, and by the materials that comer in contact with the users in a safe and secure environment, including their orientation, horizontal travel, passage through fare vending areas, training and detraining and emergency egress. Function The station’s functional design is based on the volume and needs of the flow of passengers. This starts when passengers approach the station on foot or by other modes of transportation and continues as they enter the free zone, purchase tickets, pass through the fare gates, and ascend to the platforms. Sizing Page 101 59 The stations have been sized to meet the peak hour demand for the Year 2025, including a peaking factor of 25% for the 15-minute peak period. All platforms have been designed to meet the ultimate demand. Vertical circulation in low patronage stations will have sufficient vertical circulation capacity to meet the ultimate demand. High patronage stations will have sufficient capacity for the first ten (10) years of operation, with provisions to build additional vertical circulation when it is warranted by the demand. Space and Form The quality of space and form of entrances, concourses, vertical circulation elements, and platforms will be consistent system wide, allowing for better passenger orientation and flow. Commonality The stations will have standard elements that will be consistent system wide to assist passenger orientation and flow. Common components at each station will include identification of station entrances, location of equipment such as information panels, ticket vending machines and ticket booths, fare gates, vertical circulation and platform arrangement, including lighting and signs. Passenger Comfort Comfort in stations is achieved by providing personal space along the various sequences of events that take place in the station. The design will take into consideration passenger information, easy familiarization through the commonality of the stations, clear circulation paths, easy orientation and Page 102 60 movement in crowded environments, adequate space to wait on the platforms and access the trains. Passenger Safety and Security Safety and security has been paramount in the design of the stations. Safety is dependent on providing clear sight lines and proper selection of materials that are in contact with the patrons (i.e. floors, railings, platform edge). Security personnel at the stations will provide station security. Ground level areas will be closed during non-revenue hours by an alarmed Coiling grill. Platforms will have CCTV cameras connected to the office of the Stationmaster. Station Services ƒ Station Lighting: Lighting level at stations will be high to provide a good level of safety and security. Platforms will have continuous lighting strip over the safety edge. Emergency lighting lasting at least ten (10) minutes in case of main power failure will be provided through the station. ƒ Air conditioning and Force Ventilation: None will be provide in public spaces. The stations will be designed to allow for natural ventilation and the station canopy will have a continuous ridge ventilation. Personnel and plant rooms have ventilated and/or air conditioned as required for their intended use. ƒ Public Address (PA) Speakers: All public spaces at stations will have PA speakers. Page 103 61 ƒ Public Phones: Station entrances and exterior areas will have provisions for public telephones to be installed by the telephone company. ƒ Water Supply: Each station will have a water storage tank for domestic and fire fighting purposes. The water will be pumped to the various outlets. ƒ Sanitary Sewer: Stations will be provided with septic tanks with an outflow connected to the existing sewer lines. ƒ Fire Fighting System: In public spaces, stations will be provided with dry stand pipes located as required by the fire authority.

LRTA has contacted major property owners along the proposed alignment and obtained their agreement in principle to the provision of the required right-of-way. During the Preliminary Engineering Phase of the Project, LRTA will finalize and mathematize the alignment, establish the general arrangement of the fixed facilities, and prepare right-of-way plans Page 115 73 precisely defining the property acquisition requirements for the entire project. The Program Management Office (PMO) will liaise continuously with the Department of Public Works and Highways (DPWH), Department of Transportation and Communication (DOTC), and Public Estates Authority (PEA) to keep them fully informed of the ROW definition as it evolves. Informal Settler Resettlement Some parts of the project site will require the resettlement of informal settlers by the Government in accordance with the policies of the Government and the Project Schedule. The precise extent of the resettlements required will be defined during the Preliminary Engineering Phase in conjunction with the property acquisition requirements. The PMO will liaise with the Government during the Preliminary Engineering Phase to keep them fully informed on the precise definition of the informal settler clearance as they evolve Permits and Approvals LRTA has discussed the alignment with the central and local government authorities, and with the utility companies. These agencies and authorities are already aware of the needs of the proposed Project, and are supportive of the Project. Nevertheless, various formal approvals and permits will have to be obtained in respect with the construction work. The permits and approvals shall include the following: ƒ Construction permits; · Permits for working in streets; · Approvals for traffic diversions; Page 116 74 · Approval for utility relocation and/or protection measures; · Permits and approvals for working in the Parañaque River; · Approval for disposal of excavation and waste materials, and for discharge of construction drainage water; · Approvals for environmental protection measures; and · Permits for night time working, where necessary. The PMO will start the permitting and approval processes during the Preliminary Engineering Phase of the Project. They will establish the communications and dialogues with all pertinent authorities that is essential for orderly, efficient and timely approval of construction. The permitting and approvals process will be completed during the Detailed Design and Construction Phase of the Project. Traffic Management Planning The construction of the LRT Line 1 Extension Project will affect various roads and highways. The major effect will be experienced during the construction period only thus it will be temporary. To address the traffic problems that will be brought about by the project, the Proponents formulated a sound traffic management plan, which is discussed in detail in Section 6.5, Chapter 6, Environmental Management Plan (EMP) of this Report. The said traffic management plan will be submitted to the Metro Manila Development Authority (MMDA) for approval. Utilities Management Plan The Proponents have already undertaken an examination of available utility plans for the guideway alignment to assess the impact of utility relocation, protection, and abandonment measures. A detailed discussion of the utilities management plan for the proposed project is presented in Page 117 75 Section 6.6, Chapter 6, Environmental Management Plan (EMP) of this Report. Site Demolition, Clearing, and Grubbing Site demolition, clearing, and grubbing will be undertaken in conjunction with and preceding the substructure construction. The execution of these activities will follow traditional construction methods. All waste materials shall be disposed in areas duly approved by the Department of Environment and Natural Resources (DENR). 2.4.2.2 Construction Period Guideway Construction Staging The construction of the elevated guideway for the LRT Line 1 Extension Project will be done in two (2) stages. Stage 1: Construction of the foundations on piles or caissons followed by cast-in-place concrete columns and crossheads. Stage 2: Positioning of precast concrete beams on the crossheads and field welding the bearings. The columns and crossheads will be constructed concurrently with the production of the precast concrete beams. Column construction will proceed at multiple locations in order for the project to remain on schedule, whereas the beam placement will progress linearly from Baclaran Station. Although this is the desirable sequence, beam placement has flexibility to move to a different sequence or to work at two locations simultaneously, if the site or schedule conditions require this. Guideway Substructure Construction Page 118 76 Foundation Construction The standard foundation type will be a traditional bored pile/pile cap system. After access to the column location has been accommodated and secured, the required number of piles will be installed to the required depth. The excavation will be undertaken to the bottom of pile cap, and supported with trench sheeting, where required. The excess pile lengths will be cut off, and the sub-grade for the pile cap will be prepared. Pre-fabricated rebar cages will be lowered into the excavation and the formwork will be installed. Because pile caps sizes will be standardize, reusable steel forms will be utilized in the construction of the pile caps. The quantity of forms required will be dictated by the construction schedule. The geological conditions and local geotechnical experience suggest the use of bored cast-in-place reinforced concrete piles with diameters of 1000 mm to 1800 mm . These piles are to be designed based on skin friction, and will extend from 8-22 meters in depth depending on the site conditions. For the loads and forces imposed on the guideway substructures, the foundations will consist of groups of piles with a pile cap. Pile groups will vary from 6-12 piles with an average of nine (9) piles for the guideway column. The pile cap size will vary with pile group size with an average size of 8.5 meters square by 1.3 meters deep. Where a single, large diameter caisson foundation is used, the caisson casing will be installed, the caisson will be excavated to the required depth, then the reinforcing steel concrete will be placed to form the caisson. Alternate foundation using a single diameter caisson per column has also been explored and could show some advantages in schedule and cost. Equipment availability is an issue with this type of construction and will need further investigation during the design development. Page 119 77 The installation of bored caissons within marine or river environment is difficult and costly. Driven steel or pre-cast concrete piles are typically more appropriate in these conditions but do not appear to be used to any great extent in the Manila construction market. An investigation to the availability of equipment and reliability of such installations in the local area will be evaluated during the design development phase. The geotechnical investigation has found liquefaction indicators in boreholes 1, 2, and 3 at Redemptorist, MIA, and Dr. Santos Stations, respectively. (Please see Figure 2.34 for the borehole locations) . In boreholes 1 and 3 , the areas of liquefaction risk are near surface and relatively thin. At borehole 2 , the liquefiable layer is about 9 meters below grade. Based on the conditions found at boreholes 1 and 2 , no ground conditioning has been provided for this area. In the case of borehole 3 , an allowance for downdrag on the piled foundations in this area has been provided for. In general, since the geotechnical investigation has found very little evidence of potential for surface or near surface liquefaction flow, there has been no provision for ground conditioning for any of the foundations. Column and Cross-Head Construction After the foundations have achieved sufficient strength, the reinforcing steel for the columns will be installed. Again, re-useable steel formwork will be used for the columns. The installation of this formwork will require at least one (1) crane and the installation of “dead-men”, in order to anchor the reinforcing steel cages and column forms during the stages of installation. Once the forms have been installed and checked for accuracy, the ready-mixed concrete will be placed for the columns. When the columns have achieved sufficient strength, the forms will be removed and the site will be backfilled to proper grade. Page 120 78 The steel reinforcing cages and formwork will then be placed for the crossheads will be constructed using steel formwork. These forms will be secured to the columns with friction collars in order to minimize the disruption around the columns in crowded areas. Any non-standard or special crossheads will be constructed using traditional plywood and timber formwork timber. After casting of the crossheads, a small field post tensioning procedure will take place. Substructure Construction Outside Parañaque River The su bstructure for all guideway outside of the Parañaque River will be constructed using traditional construction methods. The sequence of activities involve shall include the following: ƒ Construction of temporary access road where required; · Drill piles or construction of caisson foundation; · For piled foundation, excavation to bottom of pile cap, prepare sub- grade and cast pile cap; · Build Columns; · Backfill pile caps; and · Construction of crossheads. Substructure Construction in the Parañaque River The alignment will include a section of the guideway that will be constructed within the Parañaque River. Although the structures for this section of the guideway will be consistent with the remainder of the guideway, a different construction methodology is required. The sequence of construction activities that will be involved for this part of the guideway substructure is expected to be: Page 121 79 · Construction of temporary staging areas adjacent to the Parañaque River; · Construction of temporary docking facilities; · Dredge the river as required for construction barges; · Drill piles; and · Form and cast pile caps and build columns and crossheads. Work in the Parañaque River will comply with the Government’s environmental standards and will not obstruct river traffic. Guideway Superstructure Erection Beam Delivery Specially designed transporters will be used to move the beams from the pre- casting yard to the guideway for installation. These units have multiple axles for weight distribution and steerable rear dollies for maneuverability. The distance between the bunks can also be adjusted to the length of the beam being transported. To minimize traffic disruption, the beams will be transported at night. Beam Erection Methods for erecting the beams will vary by locations. Typically, the beams will be hoisted into position on the columns with two (2) 250-ton crawler cranes. For hoisting, the cranes will be positioned on timber crane mats. Typical crane mats will be 5 meters long by 1.5 meters wide, and will constructed of 300 mm x 300 mm timbers bolted together. Mats will be relocated by front end loaders equipped with forks and then placed by an excavator with a grapple. Cranes will move between columns on mats to protect roadways and underground utilities from damage. Every crane pick will be engineered. Page 122 80 In areas where heavy crane and transport access to the guideway is restricted, the beams will be positioned on the column using specially designed and constructed launchers. The beams will be transported to the staging locations along the guideway where cranes will hoist the beam onto temporary blocking on the erected guideway beams. At this pint, two (2) guideway transporters will pick the beam up, deliver it along the erected superstructure to the launching area, and deposit it onto temporary blocking. The launcher then hooks onto the beam and places it in its final position in the next open span. The launching cycle is approximately 2.5 hours. Figure 2.35 shows the process of erection of the guideway beams using launchers. Enumerated below are preliminary locations where beams will either be launched or be placed using cranes. · Baclaran Station to Redemptorist Station, beams will be launched; · Parañaque River Bridge to Niog Station, beams will be launched; and · Niog Station to termination of guideway, beams will be placed using cranes. Bearing Installation Bearings will be secured to the beams in the pre-cast plant prior to shipping. After installation of the beams, the bearings will be first welded to plates embedded in the top of the substructure. When this process is complete, track installation can follow. Station Structural Framing The proposed structural framing for the stations will be typically reinforced concrete one-way slabs supported on longitudinal beams. The reinforced concrete bents for the guideway structure will also constitute the primary Page 123 81 structural support system for the stations. The bents will resist the lateral forces in both the longitudinal and transverse directions. The roof structure will be typically a gable type roof consisting of structural steel purlins and tubular roof trusses which supports the roof deck insulation and roof cladding. The concept of using roof trusses to resist lateral and gravity loads eliminates the need for cross bracing and provides a clean roof system which is aesthetically pleasing. The trusses will also clear span the platform level to provide patrons with clear unobstructed space. Space trusses will be located along the perimeter of the roof except at the ends of the station. These trusses resist both lateral and uplift loads generated by wind and seismic loads. They also act to support the roof purlins and can provide a means for attaching advertising panels. The main trusses will be located generally every 20 m on center and will clear span the platform level. They will form a tree-like structure supported on cantilever concrete columns at each end of the main trusses. The proposed structural system provides the following advantages: · Reinforced concrete is a common method of construction; · The beam and slab arrangement accommodates large openings at the platform level for stairs and escalators; · Continuity and statical indeterminancy in the structural system which is preferred din an active system area; · The guideway structure can be constructed independently of the stations; and Page 124 82 · The roof structure is constructed using steel which is lightweight and has a clean appearance. Ancillary Spaces and Station Substations These secondary facilities located below the platforms the stations will be constructed of load bearing reinforced masonry walls supporting a reinforced concrete roof slab which will be waterproofed. The masonry walls will be capable of resisting both gravity and lateral loads due both to in plane and out of plane loads. The substructure will consist primarily of a continuous strip footing. The slab on grade will be raised approximately 600 mm above the surrounding grade for protection in case of flooding. Pedestrian Bridges Pedestrian bridges will be located at Redemptorist, MIA, Asia World, and Dr. Santos Stations. The primary structural system for these bridges will consist of two (2) parallel upstand precast prestressed I-girders, which will either clear span the roadway or. For wide roads, be supported on columns located in the medians. The I-girders will be of simple span design and will be supported on cantilever cross beams that will be cast at the top of circular columns. Reinforced concrete slabs will provide the walkway surface and span between the I-girders. Continuous handrails will be attached to the top face of the I- girders. At the end of the bridges, reinforced concrete stairs will be provided for patrons to enter and/or exit the stations. Foundations for the bridges will be constructed using precast prestressed piles. The piles will be driven through the softer alluvial soils to the dense tuffaceous siltstone, which is typically located 18 meters below the existing ground surface. Page 125 83 Expansion of the Existing Depot (LRTA Compound in Pasay City) The following are the construction activities that will be involved in the expansion of the existing depot within the LRTA compound in Pasay City. · site clearing and demolition of derelict barracks buildings; · site preparation and placing of sub-ballast for additional railroad; · tracks for train storage; · construction of new 3-storey Administration Building for new operating company; · new roadwork’s, drainage, sewer and domestic water supply for expanded facilities; · relocation; and · water treatment plant Satellite Depot in Bacoor, Cavite The following is a simplified chronology of construction activities involve in the · site drainage and removal of unsuitable material; · fill placement and preparation for construction of railroad tracks for storage of ten trains, including placing sub-ballast; · perimeter security fence with gate and guardhouse; · small storage facility for materials and equipment to clean interiors of trains; · relocation of existing water treatment plant; and · roadworks, drainage, sewer, domestic water and electric power Traction Power Substation Buildings Page 126 84 · eight traction power substations buildings, including concrete masonry unit buildings with concrete roofs; and · associated roadworks, storm water drainage connections and landscaping Electrical and Mechanical Systems Works · interface with existing Line 1, i.e. control recommendations power supply; · installation of traction power substation electrical equipment including transformers and switch gear; · installation of dual railroad tracks along the entire guideway, directly fastened to the guideway superstructure deck without use of ballast; · installation of ballast and railroad tracks for existing Depot expansion and for new Satellite Depot; · installation of overhead catenary power distribution system along the entire guideway, mounted on poles, located along the center of the guideway; · installation of overhead catenary power distribution system for existing Depot expansion and for new Satellite Depot; · installation of miscellaneous cables along guideway, in stations and in Depots; · installation of automatic fare collection system equipment in stations; and · installation of miscellaneous electrical/electronic equipment along in stations and at the Depot. Temporary Facilities for Construction Page 127 85 · precasting facility for the guideway superstructure beams, located on the existing reclamation area west of Roxas · Boulevard or in the future Multinational Development area south of Dr. Santos Avenue; · temporary access roads along guideway alignment where access is not possible from existing roads; · temporary bridges where alignment crosses rivers; · temporary staging areas for construction access for works in the Parañaque River; · temporary staging areas along the alignment for construction; and · offices, materials and equipment storage, etc Temporary Access Roads The guideway will traverse a very diverse land types and uses along the proposed alignment. Thus, varying degrees of construction access roads will be necessary at different locations along the alignment. These roads will be constructed as temporary accesses for construction materials and equipment, and will be designed and constructed accordingly. Several temporary bridge structures will also be required to cross various drainage ditches and other small water courses. The major effort in constructing temporary access roads will be for the section of the guideway between Dr. A. Santos and the Talaba Diversion- MCCR link Road, where much of the alignment passes through salt beds and fish ponds. For this area, an 8-meter wide access road is envisaged to facilitate the delivery and equipment, and provide ample working space Page 128 86 for construction. The construction activities that will be involved for the construction of this temporary access road will include: · drainage of affected salt beds and fish farms; · excavation of silty bed materials over width required for access road; · installation of geotextile fabric; and · construction of engineered fill road using crushed rock and granular road based materials, graded and compacted to shed rain water. Temporary Precast Yard The guideway for the LRT Line 1 Extension Project will be elevated over the entire 12-kilometer length. The basic guideway structure will consist of a pair of trapezoidal precast concrete box beam girders resting o a cast- in-place crossheads and columns. Where operational requirements or site conditions prevent the use of the typical structure, special purpose structures will be constructed thus, will become an integral part of the elevated guideway. All special purposes structures will also utilize the standard trapezoidal beam cross section. Situations that may require special purpose structures include: · structures requiring long spans; · structures requiring continuity over multiple spans; · track crossover structures; and · pocket structures Preliminary investigations indicate that approximately 843 precast concrete guideway beams will be required to complete the proposed Extension Project. Page 129 87 All beams will have the same trapezoidal box beam cross section, and beam lengths will vary from 24 meter to 30 meters. Approximately 70% of the beams on this project will be tangent and 30% will be curved. Forming System The precast concrete beams are designed to be produced in two stages. The first stage pour includes the U-shaped box beam section and the second stage pour includes the trackway slab and both parapet walls. Approved highly sophisticated forming system will be utilized to produce beams with continuously varying vertical and horizontal curvature and superelevation. In addition a high precision jigging system will locate the threaded inserts in the second stage pour for the attachment of the track hardware. Each tangent beam form, lower section, will consist of three meter tub sections and ten three meter loaf sections which will adjust only to a vertical curve. The upper section will consist of ten three meter parapet wall sections complete with the insert setting jigs. Pre-stressing of the tangent beams will be accomplished through the use of external stressing abutments and sandwich plates. The curve form, bottom section, will consist o twenty 1.5 meter long segments located adjacent to each other. Each segment will consist of an individual adjustable tub form set in a moveable frame. The individual segments will have horizontal and vertical adjustments while the tubs will be capable of being rotated within the segments. The parapet wall forms with the insert jigs for curved beams will be similar to the tangent units but will be limited to 1.5 meter lengths to facilitate forming the required curvature. Curved beams will be produced by adjusting the segments and tubs to the computer generated formset data for each beam. The post tensioning of the curve beams and the grouting will be completed in the storage and finishing area of the pre-cast facility. Page 130 88 Fabrication of the forms will take place at the form supplier’s facility. The forms will then be transported to the pre-cast yard where they will be positioned and assembled on designated beds. Once the forms have been installed they will be calibrated before going into production, and then again at regular intervals throughout the duration of beam production. Throughout the calibration sequence, quality control inspectors will verify all form positioning dimensions and certify that forms are suitable for beam production. Pre-Casting Facility A pre-cast facility, specifically designed to produce the trapezoidal box beams, will be constructed. The pre-cast yard equipment requirements are summarized in Table 2.7. The size and layout of the production facility will be determined by the Project schedule, beam production requirements, and the anticipated ratio of curve to tangent beams. Current information indicates that six (6) forms (4 tangent and 2 curved) will be required to meet the proposed schedule. This and the amount of beam storage will give the size of the site required for the pre-cast operation.

Manila LRT Line 1 Extension Offer for Implementation and Operation, Volume II Implementation & Technical Plan The forms will laid out in three rows, two rows of two tangent forms and one row of two curve forms. Each form row will have a moveable telescoping shelter on tracks which can be moved over any form to protect it from the weather during concreting operations. Since this plant will be in operation for three (3) months prior to the commencement of installation of pre-cast beams, storage for two hundred and fifty beams is required. In view of this, the pre-cast facility will require a total site area of approximately 7 hectares Page 132 90 Quality Control A comprehensive Quality Control Program will be implemented. All quality related items will be identified, monitored, and recorded. This will involve a series of inspection and sign off stages during the production cycle. Subsequent stages of production will not proceed until the current stage has been inspected and signed off verifying compliance with specifications. Pre-Casting Operations The pre-cast operation will typically require a Pre-Cast Plant Manager, a Pre- Cast Project Engineer, a Production General Superintendent, an Equipment and Maintenance Superintendent and a Pre-Cast Quality Control Engineer. Seventy- nine (79) Superintendents, 9 Engineers, 16 Inspectors and 5 CAD Operators will answer to these senior supervisors. Twenty-one (21) Foreman and 290 Trades Personnel will complete the staffing of this facility (See Table 2.8). Staff work will be staggered shifts generally beginning at 5:00 a.m. daily, at which time Quality Control inspectors will break concrete cylinders to confirm the concrete release strengths. As the day continues, beams will be removed from forms and transported to the finishing storage yard. Concurrently, other forms will be cleaned and adjusted. Rebar cages will also be placed in appropriate forms. Concrete batching and placing will begin at 1:00 p.m. Shifts will commence and end throughout the day until approximately 1:00 a.m. at which time concrete placing will be completed and the forms covered for steam curing. This routine will be completed every working day. The equipment required in the operation of the pre-cast yard is all commercially manufactured and readily available with the possible exception of the straddle carriers. Preliminary inquiries indicate a delivery time close to five months for delivery of the two straddle carriers.

Manila LRT Line 1 Extension Offer for Implementation and Operation, Volume II Implementation & Technical Plan Disposal of earthworks materials/construction spoils are yet to be finalized. However the exact location of these sites shall be submitted to the DENR for approval prior to disposal. 2.4.3 Operational Phase The LRT 1 Line Extension shall be opened to traffic after the construction period of 3.5 years. 2.4.3.1 Train Configuration and Fleet Size The fleet will be configured into four-vehicle trains with a total length of approximately 108 meters based on a 27-meter nominal length for a light Page 139 97 rail vehicle with single articulation. The design capacity of each 4-vehicle train is 1,358 passengers at a total density of seven (7) passengers per square meter standing and peripheral seating arrangement. The fleet size is calculated for initial and ultimate system capabilities of 17,000 and 30,000 passengers per hour per direction (pphpd) respectively, based on a design capacity of 1,358 per train. For the initial operation (Year 2005) , the Project will require an operating fleet of ten (10) trains plus one (1) spare train for a total of forty-four (44) vehicles. For the ultimate operation, it will require an additional operating fleet of six (6) trains for a total of twenty-four (24) vehicles. 2.4.3.2 Operating Schedules and Service Levels The integrated LRT Line 1 will provide service 17.5 hours per day for 365 days per year. The full system is in operation from 0500-2230 hours . Outside these hours, start-up and shutdown periods are required for trains to build up service and, at the end of the day, to finish their run and return to the depots. For a weekday, the passenger demand and corresponding service levels can be classified into peak and off-peak periods. The existing LRT Line 1 currently has two (2) peak periods on a weekday from 0600-0800 hours and from 1600-1900 hours . The present service level of the existing Line 1 in the midday off-peak period is 80% of the peak period. The fleet deployment diagram shown on Figure 2.38 illustrates the typical existing service profile for LRT Line 1, which similarly be followed for the LRT Line Extension. The percentages shown are approximate and refer to the active fleet. The routine fleet arrangement through a normal operating day comprises: Page 140 98 · Fleet mobilization and build-up to 60% level; · Build-up to 100%; · Peak-hour operation; · Fleet reduction to 80%; · Midday operation at 80% level; · Build-up to 100%; · Fleet reduction to 60%; · Operation at 60% fleet level; and · Service phase-out and fleet removal Table 2.13 presents the active fleet sizes, fleet allocation on the existing and the Extension segments, and headways for two-system configurations and operating modes. It should be noted that values displayed are projections and may change somewhat with the implementation of the Project to suit the Phase II Capacity Expansion Project. Water Supply and Demand Water supply requirement for the construction activities will be sourced from existing water districts through huge water tankers. During the operational phase, water usage shall be minimal, and limited to domestic use only, i.e., for usage in, and maintenance of comport rooms. 3 BASELINE ENVIRONMENTAL CONDITIONS 3.1 Environmental Study Area……………………………………. 3-1 3.2 Physical Environment…………………………………………. 3-1 Page 141 99 3.3 Biological Environment…………………………………….... 4-43 3.4 Socio-Economic Environment……………………………… 3-50 3 BASELINE ENVIRONMENTAL CONDITIONS 3.1 Environmental Study Area The proposed LRT Line 1 Extension will traverse three (3) Cities in Metro Manila namely, Pasay, Parañaque, and Las Piñas, and the Municipality of Bacoor in the Province of Cavite. Page 142 100 In assessing the possible impacts of the proposed project to the recipient communities, the following delineation was used. The Direct Impact Area (DIA) refers to areas within the construction limit (within the Right-of-Way) that will be directly affected by the construction activities, by way of physical displacement of houses and improvements. The Indirect Impact Area (IIA) on the other hand refers to areas which will be indirectly affected by impacts such as increase in noise levels and NO x , SO x , and TSP levels, traffic congestion, and the like. See Figure 3.1. 3.2 Physical Environment 3.2.1 Geomorphology The project area lies on the delta plain bounded by the Manila Bay on the west, the western flank of the Guadalupe Plateau on the east, and the slopes of the Tagaytay highlands at the south. The slopes of these highlands serve as the catchment areas for the river systems that bisect the project area. The Parañaque and Las Piñas River, and their contributaries drain from the slopes Guadalupe Plateau, on the other hand, the Zapote River drains from the Tagaytay Highlands. At present, the plain is fully developed and highly urbanized, which altered the inherent features of each geomorphic unit. From the coastline, the original terrain shows a tidal flat, beach ridges, marsh-backswamp, crevass splay, and tidal channels. The eastern edge of the corridor fringes the distal edge of the volcanic apron of the Tagaytay Highlands. The overall terrain development occurred during the last sea level regression. Terrestrial sediments delivered by the river systems into the coast where reworked by the coastal dynamics and processes operating along the coastline. These sediments where eventually deposited and reflects their environment of Page 143 101 deposition. The continued sedimentary accretion contributed to the seaward progradation of the coastline, synchronous with sea level retreat. Geomorphologic Features As shown on Figure 3.2.1 and summarized on Table 3.2.1 , the geomorphological features identified in the project area are the following; Tidal Flats Tidal flats are featureless plains bordering the seaward side of the strand line dissected by a network of tidal channels. During flood period, tidal waters enter the channels, overtopping the channel banks and inundate the adjacent flats. Following the period of slack water, the tidal water drains via the channels and re-exposes the flats. The terrain is generally covered with fine-grained detritus and mud, subject to inundation by the rise and fall of the tide. These materials are deposited in the zone between the low tide limit and the maximum swash line. Backswamps Backswamps are topographically low areas on the landward side of the beach ridges and serves as natural repository of floodwater from the high land and is subject to inundation during high tide. Meandering tidal channels bounded by levees serves as the water conduits. Abandoned channels, which are filled up channel lines, reflected as longitudinal depressions in aerial photographs are common. Pockets of mangrove vegetation are present in some segments bordering the river channels in the area. Page 144 102 Backswamps are commonly used as fishpond during the rainy season and as salt beds during summer. Large sections are extensively filled up which are used as housing, industrial, and commercial site. Fill materials varies from garbage, construction spoils, and other undifferentiated materials. Beach Ridges/Coastal Dunes Beach ridges/coast dunes are essentially longitudinal continues mounds of low relief along the coastlines. These topographic features run parallel to the dominant wind direction and were formed by the deposition of sand transported by longshore current. These are sediments derived either from those delivered into the sea by the river systems or those from offshore areas and are reworked and redistributed along the coastline. The seaward progradation is the beachfront response to the rich sediment influx and sea regression. Alluvial Lobes and Crevasse Splays Alluvial lobes are fan-shaped features formed by the dumping of sediments debris from the highlands, and those deposited by the river systems such as th e upstream portions of Parañaque River. Crevasse splays are tongue-shaped deposits of sediments along the banks at the upper portion of Zapote River, particularly along the Alabang- Zapote Road. The deposits were laid when flood waters overtopped the channel banks.

Abandoned Channel Deposits Abandoned channel deposits are mainly fining upward sequence of unconsolidated very poorly sorted very sandy gravel, very gravelly very coarse to fine sand capped by humic fine sand and silt. The gravel and coarse sand are sub-rounded to well-rounded. Active Channel Deposits Active channel deposits are unconsolidated, very poorly sorted sand, and gravel with size ranging from coarse sand fraction to very coarse gravel. Layers of silt, clay, and mud are also present. Due to the high concentration of hydrocarbons in the polluted waters of these channels, there is a possibility for the presence of fluid mud, composed of dense mass of very plastic layer silt and clay at the bottom of the channels. Backswamp Deposits Tidal marsh deposits are mainly very humic dark grayish to black silty, clayey fine to medium sand with moderately well sorting. These deposits are rich with moderately decomposed vegetable remains. Poorly sorted gravelly coarse to medium sand serves as the basement. Page 147 105 Beach Sand Deposits Beach sand deposits are mainly very loose poorly sorted coarse to medium sand and gravel. Gravel sizes range from fine to coarse fraction, and are either well-rounded or flat. Alternating lenses of gravelly sand and sandy gravel are common. Beach sand deposit inter-tongue with back swamp and tidal flat deposit. Tidal Flat Deposit Tidal flat deposits are bioturbated, fine and medium sand inter- layered with silt and clay concentrated along the seaward side of the strand line. Accretion is mainly caused by deposition of suspended sediments during high tides. Fill and Reclamation Materials Fill and reclamation materials are accordingly defined based on the materials used. Those used in filling in low-lying areas within the backswamp are classified as fill materials, composed of garbage, construction spoils, and other undifferentiated materials. On the reclamation areas along the Manila Bay coastline, the materials used are hydraulic fills of sand sourced from offshore. These materials have varying engineering and foundation properties, where sand and those of pre-identified filling materials are more predictable, thus appropriate measures could easily be applied. 3.2.3 Stratigraphy Compilation of available core logs from earlier projects done in the vicinity of the proposed project corridor shows three (3) major geotechnical/geological zones and are presented on Figure 3.2.2. Page 148 106 The topmost layer (Zone 1) is recent unconsolidated marine material predominantly comprised of clay and sandy silt or silty sand becoming firm at the bottom near the contract with the second layer of sand and gravel. The N-value is commonly 1 to 2 and rarely goes beyond 6 . Minimum thickness is 1.5 meters to 12.5 meters. The second layer (Zone II) is a Pleistocene to Recent marine deposit that persists to the top of the third zone of tuffaceous sandstone bedrock. Its N value varies from a low of 20 to greater than 50 and is therefore substantially compacted. Zone III is the underlying bedrock where Zone II rests. It is made up of a series of low dipping beds of volcanic derived tuffaceous and conglomeratic sandstones. The zone is very dense to very hard with N values greater than 60. A geological cross-section perpendicular to the Pasay-Zapote Coastline is presented on Figure 3.2.3. 3.2.4 Seismicity Based on records, Metro Manila had experienced numerous earthquakes in the past. Listed on Table 3.2.2. are twenty-eight (28) of these events, but are by no means complete as other events less than Intensity VII are not included. On the average, Manila is likely to be hit by a perceptible (Intensity IV) earthquake every year and by a destructive earthquake once every 15 years . A rough estimate of the average return period for Intensity VIII earthquake such as the 1990 Baguio earthquake is about 79 years based on five events that occurred from 1599 to 1970. Records also show that four (4) extremely strong events (Intensity IX) occurred from 1645 to 1863 with an average return period of 54 years . An extremely strong earthquake has not shaken the metropolis for the last 130 Page 149 107 years. However, available instrumental data during the last century suggest that the return period for such big earthquake could be as low as 250 years (J.A. Daligdig & G.M. Besana 1993).

Adopted from J.A. Daligdig & G.M. Besana 1993 3.2.5 Earthquake Generators The more important potential earthquake generators likely to affect the Metro Manila area are the Manila Trench, Philippine Fault, Lubang Fault and the Marikina Fault. Instrumental data exist on the recent activity along these first Page 151 109 three sources of earthquakes, some of which has caused considerable damage to the city. As for the Marikina Fault, although no historical seismic event can be definitely related to it, the fault cuts across the eastern fringes of Metro-Manila. (See Figures 3.2.4 – Active and Suspected Faults and Seismic Sources in Central Luzon) Manila Trench The Manila Trench is located west of Luzon and extends from Taiwan in the north to Mindoro in the south. The trench marks the trace of the subduction of oceanic crust of the South China Sea Basin underneath the Luzon arc. It is associated with an active volcanic arc which includes Mt. Pinatubo. The trench is expressed as a narrow but deep bathymetric feature that reachers a maximum depth of 5,100 meters west of Manila. The deformation of trench sediments, as seen from seismic reflection profiles taken across the trench, also shows that the trench is active (Hayes and Lewis, 1984) The Manila Trench is a major earthquake generator. The distribution of earthquake foci defines a belt which dips to the east to a depth of 220 kilometers ( Hamburger et al, 1983). Focal mechanism solutions are those of thrusting events. It has been suggested that the 1677 and 1863 earthquakes might have been triggered by this Trench. The first occurrence resulted in the generation of tsunamis hitting the western coast of Luzon and fissuring in Manila. The second likewise resulted in tsunamis and the collapse of numerous buildings due to ground shaking.Extensive fissuring, liquefaction and seische along the Pasig River were also observed ( Daligdig and Besana, 1993). Page 152 110 Philippine Fault The Philippine Fault is a major left lateral strike slip fault that cuts across the entire length of the Philippine archipelago. It is an intra-arc wrench fault located behind a zone of oblique convergence. The concept of shear partitioning ( Fitch, 1972) predicts that the Philippine Fault must have accommodated the trench-parallel component of the Eurasian-Philippine Sea Plate convergence. This last attribute, together with the Philippine Fault being a basement-cutting fault, have not been highlighted in early descriptions. Lubang Fault The Lubang Fault is a major left lateral strike slip fault that branches off from the Philippine Fault near Masbate and continues along the Verde Passage between Luzon and Mindoro towards the Manila Trench. This fault is seismically important and is associated with left lateral strike slip focal mechanism solutions. Although the main fault passes south of Lubang Island, a possible branch passes between the island of Lubang and Ambil. Marikina Valley Fault System The Marikina Valley Fault System consists of the East and West Marikina Fault. The West Marikina Fault extends over a distance of 90 kilometers from north of Amang Rodriguez to the Tagaytay Ridge. Its east-facing scarp is slightly curvilinear. Its trend varies from NNE-SSW along its northern portion to north-south / NNW-SSE along its southern portion. The height of this scarp varies along strike from 100 meters west of Amang Rodgriguez to a much higher values where the fault forms the eastern limit of Tagaytay Ridge. Where the Pasig River crosses the West Marikina Page 153 111 Fault, the scarp measures 30 meters and the river entrenches itself in the Pleistocene Guadalupe Formation. Surface water usually follows the shortest route downslope and streams are therefore expected to follow the regional slope of an area. However, in the Muntinlupa area, the streams trend NNE-SSW, oblique to slope produced by West Marikina Fault scarp. These streams are clearly fault- controlled and correspond to a series of NNE-SSW faults. These structures have been interpreted as being due to pull-apart basin formation. However, such an interpretation requires the presence for a second major strike slip fault to the west but the presence of this fault still has to be demonstrated. These oblique faults are instead interpreted as faults in riedel position to the West Marikina Fault. These en echelon faults are definitely active and actual displacements in man-made structures have been made. The shorter East Marikina Fault extends for more than 20 kilometers from north of Amang Rodriguez to Marikina. However, its southern termination is less clear and the fault may continue for another 20 kilometers towards Laguna de Bay. Its west-facing escarpment is likewise curvilinear. Its trend varies from NNE-SSW near Amang Rodriguez to NNW-SSE near Angono. The fault scarp has a maximum height of 450 meters east of Rodriguez and likewise cuts the Guadalupe Formation to the south. Although the exact deformation history of the Marikina Valley is unknown, important vertical displacements are predicted. Trenching by PHIVOLCS across the East Marikina Fault shows both thrust and strike slip components. In Brgy. Pututan, Muntinlupa City, vertical displacements of up to 40 centimeters has occurred along the en echelon faults since 1990. That the fault is definitely active is exhibited by displacements of Page 154 112 man-made structures in Brgy. Pututan and the thrusting of basement rocks over recent alluvium as observed from the trenches. 3.2.6 Hazard Identification Geological Hazards The existing geological, geomorphic and tectonic conditions posses certain geological hazards that will affect the project. These include 1) ground shaking, 2) ground rupture, 3) liquefaction, and 4) floods. The three are directly caused by earthquakes due to the presence of earthquake generators near the area, the last is consequent to the areas geologic and geomorphic setting. 3.2.6.1 Ground Shaking Strong ground vibrations caused by the passage of seismic waves from the earthquake source (foci) to the ground surface may cause damages to the proposed project. The intensity of ground shaking in a given area is influenced by the magnitude of the earthquake, distance of the site from earthquake generator, and the modifying effects of subsoil conditions, Usually, the shallower the earthquake source and the close the area from the epicentral area, the stronger is the felt intensity within the particular site. The resulting possible damage can be exuberated by the quality of the materials used, the quality of the design and the mode of construction. Maps from previous workers had shown the probable level of ground shaking on a regional context, where the intensity of the ground shaking is usually translated into percentage of the ground acceleration (g). These hazard maps took into Page 155 113 consideration the contribution of all possible earthquake generators within a broad area for certain span of time ( e.g. 100-year return period) and the result expressed in probabilities (e.g. 90% of non-exceedence). Recent works of Bautista et.al (1992) shown on Figures 3.2.4a & 3.2.4b predict ground acceleration (PGA) of values of 0.15g to 0.17g for a 50- year return period and 0.20g to 0.22g for 250 years. However, the study did not incorporate the Marikina Fault system as a source of their model. Activity of the Marikina fault is difficult to quantify at present due to absence of instrumental records of seismicity. The inclusion of this information could considerably alter the map of probable levels of ground shaking. Possible ground acceleration in Metro –Manila prepared by Daligdig and Besana (1992) used an attenuation relation derive by Fukushima and Tanaka (1990) in combination with historical, instrumental and empirical seismicity data. It is based on the hypothetical assumption that a magnitude 7.5 earthquake is generated from the Marikina Valley Fault System (MVFS) as presented on Figure 3.2.5. In terms of ground shaking, it is assumed that a magnitude 7.5 from MVFS as a worst case scenario for Metro Manila. The PGA values may reach up to 1.0g within the epicentral area for areas underlain by soft soils, while those with bedrock close to the epicenter could experience PGA of about 0.4g. This is likely to be experienced in Marikina Valley and in the northern and western coastlineof Laguna de Bay, followed by the areas on the Pasig River delta plain towards Zapote-Bacoor with PGAs of 0.4g to 0.8g. An earthquake with a magnitude of 8.0 generated at the Philippine Fault segment east of Quezon could generate PGA within at the Metropolis in the order of magnitude of 0.4g and 0 . 15g for soft and hard rock conditions respectively. For other earthquakes generated further away from the metropolis, PGA of 0.18g or lower may affect Metro –Manila (PHIVOLCS 1993). Page 156 114 3.2.6.2 Grounds Rupture Surface rupturing of the breaking and movements of the ground along an active fault trace could result to horizontal/vertical shifting of the ground or a combination of both. Damage can be severe for structures directly straddling and located within a narrow zone of the active fault traces. For the 1990 earthquake, the deformations zone range from 5-10 meters from the surface rapture. The location, pattern, and style of surface faulting generally appear to occur along pre-existing active fault traces, hence the precise delineation of these traces is very important in mitigating the damages due to surface rupturing. At present, there is an unconfirmed extension of the East Zambales Fault which runs along eastern Zambales, crossing the western part of Parañaque city (project area), and extends southeast to Laguna de Bay (Yumul 1997). It is possible that ground rapture may occur along the route corridor if the fault line is really present. 3.2.6.3 Liquefaction Soil liquefaction is phenomenon in which a soil deposit below the groundwater table loses a substantial amount of strength due to strong earthquake ground shaking and becomes fluid-like. Some soil type tend to compact during earthquake shaking; this tendency for compaction will induce excess pore water pressures in the soil that, in turn, causes a reduction in strength of soil. A liquefied soil becomes fluid-like and this condition may continue for some period of time following the earthquake, depending on the soil permeability and drainage conditions, until the excess pore water pressure dissipates. The route corridor is an old tidal flat area, which is commonly underlain by layers of silt, sand, and clay. These materials are highly susceptible to liquefaction. However, this tidal flat area has been modified by large backfilling and reclamation that hampered the identification of zones susceptible to liquefaction. Page 157 115 Potential consequence of liquefaction includes: · Reduction or loss of foundation-bearing strength that can lead to large settlements due to shear failure in the weakened soil; · Flotation of the light-weight structures embedded in the liquefied soils. · Differential compaction due to soil densification as excess pore water pressures dissipate, which can lead to differential settlements in the structure foundation; · Lateral movements due to lateral spreading or flow sliding of liquefied soils can lead to total and differential movements of the structures; · Increase lateral pressures on the retaining walls; · Settlements hazards due to sand boils which involves ejection of liquefied soils to ground surface through vents; and, · Gound oscillation where ground overlaying liquefied soil experiences large displacement transient oscillations that results to fissures, buckling and thrusting of structures. Factors affecting Liquefaction Susceptibility The primary factors affecting the susceptibility for liquefaction are as discussed follows: Composition of the Soils Youd and Perkins present an empirically based correlation that relates the geologic age and environment of deposition to liquefaction susceptibility as shown on Table 3.2.3. Geologically young (less than 500 years old), relatively unconsolidated cohesion less soil, which occur locally in river Page 158 116 channels, food plain, uncompacted artificial fills etc. are expected to have a high to very high susceptibility for liquefaction if they occur below ground water table. The depositional environment of the soil has a strong influence on the grain size distribution and the relative density and structural arrangements of gains. Geologic provenance (i.e. the nature of source area) also has strong influence in the composition of the deposit. Sand and silty sand are particularly susceptible to liquefaction. All cohesion less soil (silt and gravel) and some sensitive clays have exhibited liquefaction – type strength losses are susceptible to liquefaction. Table 3.2.3 Classification for Liquefaction Susceptibility Livelihood that cohesion less sediments when saturated, would be susceptible to liquefaction (age of deposit) Type of Deposits General distribution of cohesion lees sediments in deposits <500 yr Holocene Pleistocene Pre- Pleistocene Continental Deposit River channel Locally variable Very high High Low Very Low Flood Plain Locally variable High Moderate Low Very Low Alluvial fan & plain Widespread Moderate Low Low Very Low Marine terraces & Plains Widespread Moderate Low Low Very Low Delta & fan- delta Widespread High Moderate Very Low Very Low Coastal Zone Delta Widespread Very high High Low Very Low Estuarine Widespread High Moderate Low Very Low Beach Widespread High wave energy Widespread Moderate Low Very Low Very Low Low wave energy Widespread High Moderate Low Very Low Lagoonal Widespread High Moderate Low Very Low Fore shore Widespread High Moderate Low Very Low Artificial Page 159 117 Table 3.2.3 Classification for Liquefaction Susceptibility Uncompacted fill Widespread Very high Compacted fill Widespread Low After Youd and Perkins, 1978 Relative Density and Structure of the Soil Soils that have higher relative densities and more stable soil structure have a lower susceptibility to liquefaction. With increasing age of the deposit, relative density tend to increase as particle gradually work closer together, through slight particle reorientation and cementation. Thickness of overburden also increase with age and increased pressure associated with thicker overburden tend to increase the density of the soil deposit (Youd & Perkins, 1978). The SPT-N values are good indicator of soil density since as relative density increases the SPT blow (N-values) also increase. Groundwater Level or State of water Saturation Soil must be saturated to liquefy thus liquefaction susceptibility of a soil is varies depth to groundwater where an increase in depth of groundwater lowers th e soil deposit’s susceptibility to liquefaction. Groundwater level may vary substantially between wet and dry season and this must be taken into consideration in the analysis of the groundwater level. Cohesionless soils that lie above the highest seasonal level groundwater are considered to have a very low susceptibility to liquefaction. Soils below groundwater have decreasing susceptibility as the depth of groundwater overburden increases. Page 160 118 Liquefaction Hazard Zonation Based on the distribution of the Quaternary deposits and their susceptibility to liquefaction as characterized, zones having uniform susceptibility to liquefaction were defined on Figure 3.2.6. The presence of soft saturated unconsolidated material with very low N values up to a depth of 10 meters from the surface along the reclamation site makes the area a high risk zones for liquefaction. Tidal flat, backswamp, abandoned channels where also included due to the likely presence of similar materials. Areas underlain by substantially compacted beach sands with are classified as moderate risk areas. Areas with near surface presence of bedrock overlain by relatively thin alluvial materials area classified as low risk areas. 3.2.6.4 Flooding Flooding is a recurrent problem that poses difficulties and danger especially to low-laying areas with inadequate drainage system such as Parañaque and Las Piñas. In flood control and drainage study of Metro Manila by JICA in March 1990, the Parañaque-Las Piñas area was identified as a “lowland along the Manila Bay” which “received serious flooding in 1986 due to the inland water as well as the flooding of the river.” Aside from climatic condition, other factors that contribute to flooding are, rapid urbanization, inadequate to non-existent drainage system, improper waste disposal and clogging, low river capacity and lack of maintenance, Page 161 119 tidal transgression, squatter encroachment along water ways, institutional problems and financial constraints. Flooding within the project areas could be classified in to two (2) general categories namely channel floods and basinal floods as shown in Figure 3.2.7 Channel floods are confined along the channel systems characterized by relatively swift flow velocity and flood level rise. Flood periods are short, relative to duration and intensity of the rain. This commonly results to over bank flow, inundating the adjacent low laying areas. River channels in the area if not buried in debris, have very low water capacity, which impedes the flow toward Manila Bay. Basinal floods commonly occur on the tidal flat and backswamp areas, consequential to the very flat gradient and low topography making these areas natural flood basins. Period of inundation takes a longer time to recede. This is aggravated when high tide in Manila Bay impedes the outflow of waters through river systems. Filling of large section of the original flood basin further complicated the flood problem. 3.2.7 Surface Hydrology River Systems Along the Route Corridor Drainage within route corridor is served by three (3) major drainage systems (i.e. Parañaque, Las Piñas , and Zapote Rivers) that empties into the Manila Bay through two (2) main outlets as shown in Figure 3.2.8. Within the coastal plain, the river course is morphologically controlled, running parallel to the coastline following the land ward boundary of the beach ridges and exhibits a meandering course. This area also acts as natural catch basin surface water coming from the Page 162 120 flanks of Guadalupe Plateau and Tagaytay Highlands. The flow in the coastal Plain is generally sluggish, dominated by standstill water condition. This is mainly caused by the influence of tidal fluctuations and the terrain’s flat topography with elevation ranging from 2 meters below sea level in some sections just to 3 meters above sea level. The Parañaque River that merges with the Las Piñas River drains the northern end of the corridor before flowing into the manila Bay through an outlet channel in Brgy. La Huerta, Parañaque City. Both rivers drains the highly urbanized western flank of the Guadalupe Plateau, where the Parañaque River catches the drain water from area of Malibay, Dasmariñas Village and Fort Bonifacio while Las Piñas River receives the drain water from the municipalities of Las Piñas and Parañaque. The Zapote River serves as the main river system at the southern ends of the project area. The watershed area stretches south to Dasmariñas, Cavite at the northern flank of Tagaytay Highland. The river’s tributaries and gullies are vertically incised marked by steep gully walls and shows parallel pattern. Initially the watershed areas where open space grass and farmland as illustrated on Figure 3.2.9. This allowed infiltration from surface runoff from rainwater into the porous bedrock of tuff and vulcanoclastic debris. At present the watershed area of the Parañaque and Las Piñas river are highly urbanized while that of the Zapote River are being developed at an accelerated rate. Urbanization in the watershed areas had affected the hydraulic regime of the river systems by changing the discharge characteristic as well transported load. The development had replaced the natural fields and grasslands, degrading the river systems and increased the discharge several folds. Flood becomes frequent and loads increase. Consequently, less water is able to infiltrate into the soil due to paving of large areas. The affects runoff by causing the peak discharge to oocur in a shorter period of time a storm with increased flood flow velocity relative to the duration and rain intensity. Page 163 121 The natural gullies now as the receiving conduits for storm drains. During the dry months, channel flow is mainly derived from domestic sewage with very minimal base flow. Flush flood condition occurs during the rainy months, as storm runoffs from storm drains are collected and channeld into the catchment basins at the coastal palins. The catchment basin at the coastal plains on the other hand had been converted into fishpond and salts beds. Large areas where filled up and reclaimed, and the banks of channel system encroached with various forms of structures. The construction of water channels is aggravated by rapid siltation through uncontrolled damping of garbage. Though various alterations have been made, the function of the area is still and will remain a catchment basin for runoffs coming from highlands thus making it prone to floodings.

River Use The existing coastal road and dunes provide a natural protection from strong waves for the fisher folks settled along the riverbanks near the mouth of Parañaque, Las Piñas, Zapote Rivers. These fishers folks using boats with outriggers, only use the rivers as access to their fishing grouds in Manila Bay. These boats are docked along sections of the riverbanks. Aside from navigation, river water is used in stocking the fishponds and salt beds along the channel banks. Tidal Regime Baseline data provided here are on tidal fluctuations in Manila Bay since the project area is primarily influenced by this waterbody. Tidal ranges and cycles at the Manila Bay are being observed and recorded by the Hydrographic and Geodetic Survey Department of the National Mapping and Resource Information Agency (NAMRIA) using a tide gauge installed at Pier 15 of the Manila South Harbor (BM 4B). The following table shows the list of datum planes for Manila Bay from 1970-1988: Page 165 123 Datum Plane for Manila Bay, Series = 1970-1988 Tide Component Elevations in Meters Above Mean Lower Low Water (MLLW) Bench Mark (BM 4B) 3.240 Mean High Water (MHW) 0.858 Mean Sea Level (MSL) 0.475 Mean Low Water (MLW) 0.100 Mean Higher High Water (MHHW) 1.003 SOURCE NAMRIA, 1999. Tide and Current Tables. Oceanography Division, Hydrographic and Geodetic Survey Department. 243 pp. Hydrology and Flooding As mentioned in Section 3.2.1 of the EIS document, the project area lies on a fully developed, highly urbanized, delta plain. It forms part of the low-lying areas of Metro Manila, bound on the west by the Manila Bay. These areas mainly consist of tidal flats and marsh-backswamp areas with beach ridges, crevasse splays, and tidal channels in between. This geomorphologic setting makes these areas highly susceptible to flooding. The situation is much more aggravated by the effects of rapid urbanization and development---land filling of large sections of the original flood basin, inadequate to non-existent drainage system, improper waste disposal, and squatter encroachment along river banks. There are three (3) major river systems draining the Parañaque and Las Piñas areas namely the South Parañaque River, the Las Piñas River, and the Zapote River. These are interconnected by the San Dionisio and Parañaque River. The three major waterways cause serious flooding to the area due to river channel overflow (JICA, 1990) . The lower and middle reaches of the South Parañaque River and its major tributary, the Dongalo River, are affected by tidal fluctuation. Page 166 124 As a result, the bankfull flow capacity becomes almost nil when the tidal level of the Manila Bay rises to near its mean spring high tide of 11.30 m . In the same manner, about 5-km stretch of Las Piñas and Zapote Rivers is likewise affected by tidal fluctuation. During the high tide regimes of the Manila Bay, the bankfull flow capacity in the downstream of Las Piñas River is also almost nil , with the middle stream having about 10m 3 /s of the bankfull flow capacity. Based on the aforementioned 1990 JICA Study, low areas along the Parañaque- Las Piñas area that suffer from flooding due to inland water (catchment area) cover around 1,543 hectares . 3.2.8 Land Use 3.2.8.1 Existing Land Use Types General land use types in the Project Area (Cities of Pasay, Parañaque, and Las Piñas, and Municipality of Bacoor) mainly consists of the following: (i) Low to Medium Residential, (ii) Mixed Residential/Commercial, (iii) Industrial, (iv) Mixed-Use Agricultural, and (v) Reclamation Area. Due to its proximity to the business districts and highly urbanized areas of Metro Manila such as the Makati Central Business District (CBD), the Ortigas Sub-Urban Center, and the Manila CBD, it has become an extension of these growth areas, and is rapidly developing into suburban communities and satellite subcenters. Pasay City The Ninoy Aquino International Airport and appurtenant facilities occupy more than fifty percent (51%) of the land area of Pasay Page 167 125 City (Pasay City Socioeconomic Profile, 1999). Reclamation areas intended for future development commercial zone comprise around 19% , and the rest (30%) consist of residential, commercial, industrial, institutional, and cultural. Commercial development in Pasay City occurs along major roads such as Taft Avenue, Antonio S. Arnaiz (Libertad), Gil Puyat (Buendia), F.B. Harrison, Roxas Blvd, and EDSA. Due to its limited land area, “mixed zones” of residential and commercial use are common. Only a small portion of Pasay City shall be traversed by the Project (i.e., from existing depot to boundary with Parañaque City near Redemptorist). Parañaque City Existing land use types mainly consist of the following (i) Residential (51.79%) , (ii) Reclamation Area (17.76%) , (iii) Commercial (11.92%) , (iv) Industrial (11.49%) , (v) Institutional (3.81%) , (vi) Utilities (NAIA, 2.67%) , (vii) Creeks and Rivers (0.73%) , and (viii) Open Spaces/Parks and Playgrounds (0.30%). Residential areas constitute the largest portion of Parañaque City, starting from Barangay Tambo, down to the other barangays of the City. Commercial areas, just like other urbanizing cities, are concentrated along main highways such as Ninoy Aquino and Dr. Santos Avenues. However, Parañaque’s principal CBD remains to be Barangay Baclaran, which is also the seat of the popularly known Baclaran Chuch. In the absence of an Existing Land Use Map for Parañaque, the Proposed Land Use Map is presented as Figure 3.2.10. Page 168 126 The Project shall traverse Barangay Baclaran along Redemptorist Street, as well as the fast growing corridors along Ninoy Aquino and Dr. Santos Avenue. Other influence areas are mainly residential to mixed residential/commercial in Barangays Tambo(including Uniwide Coastal Mall and other medium to large business establishments along the Coastal Road), Dongalo (including a portion of Asiaworld Properties and Barangay Don Galo Sports Complex), San Dionisio, and La Huerta. Las Piñas City Land use in Las Piñas City is mainly dedicated to the following: (i) Residential (low density, medium density, and high density) (ii) Commercial (primary, secondary, tertiary), (iii) Industrial (light industrial zone, medium industrial zone), (iv) Institutional, (v) Saltbeds/Fishponds, (vi) Vacant/Open Areas, (vii) Parks and Playgrounds, and (viii) Utilities. Please refer to Figure 3.2.11 Among the different types of residential areas, the Medium Density development areas comprised of 1, 133 hectares make up the majority. This is followed by the High Density development areas (268 ha) , which are located mostly in blighted areas in the City’s northern fringes facing the coastline, in vacant lands and open spaces, and towards the southern limit. Only 35 hectares of land is occupied by the Low Density residential areas. These are mostly found at the eastern portion of the City. Commercial establishments and large shopping malls (i.e., Shoe Mart South Mall, Manueala Metropolis, and Filinvest City) are located along the Alabang-Zapote Road. Several manufacturing firms comprise the industrial establishments occupying about 136 hectares . These are located along the Alabang-Zapote Road Page 169 127 corridor, Barangay Pamplona Uno, Pamplona Tres, Talon Singko, Pulang Lupa Dos, and BF International. Out of 1,038 hectares of open spaces, vacant lands, and reclaimed areas, only 40 hectares are dedicated to parks, playgrounds, and other recreational uses. The rest have been planned for various urban uses. The influence areas in Las Piñas City are fishponds and salt beds in Barangay Manuyo Uno and Pulang Lupa, and residential/commercial areas also in Barangay Pulang Lupa. Municipality of Bacoor Based on the Provincial Physical Framework Plan/ Comprehensive Provincial Land Use Plan of Cavite, Bacoor, along with the Municipalities of Dasmariñas and Imus, having populations more than 100,000 are classified as small cities. They are envisioned as the international production and distribution centers on industry and commerce. The influence areas would be Barangays Longos/Zapote 5 and Talaba 2 (residential) and Barangay Talaba 4 (commercial/institutional). Page 170 128 3.2.8.2 Proposed Future Land Use Among the development areas in the above mentioned Cities and Municipality, the Las Piñas –Parañaque Commercial Zone (LP-PCZ), a planned commercial development area is deemed as most compatible with the proposed Line 1 Extension Project. The LP-PCZ occupies approximately 160 hectares of land, most of which are presently used as salt beds and fishponds. This area has been classified by the City of Las Piñas as High Density Commercial Development (C3). It is located east of the Ninoy Aquino Avenue and Tramo Road, along the tributaries of Parañaque River (Please refer to Figure 3.2.12 ). Aside from the planned commercial/residential subcenter, it will also include a 250,000-person capacity stadium/ampitheater for religious services. In terms of infrastructure support, a C-5 link is planned to dissect the LP- PCZ, plus a new six-lane north-south spine road that will skirt the eastern edge of the development area, and provide a link from Dr. Santos to Quirino Avenue. 3.2.9 Pedology Pedologically, soil cover is absent in the study area. Those present are Hydrosols, composed of unconsolidated layered and intertonguing silt, clay and sand of marine origin. These are commonly overlain by uncharacterized fill metrials due to extensive reclamation / backfilling works done in large areas along the Bacoor-Zapote-Baclaran coastal plain. On the geotechnical sense, these materials where described as soft and loose marine deposit found overlying tuff materials classified as Guadalupe Tuff as observed from the five (5) boreholes done along the route (Figure 2.34). Page 171 129 3.2.10 Water Quality and Limnology Water samples were collected from the rivers and creeks traversed by the proposed Extension Project. Seven (7) sampling stations were selected (Figure 3.2.13). Field measurements were taken for temperature and pH using a thermometer and a digital pH-meter, respectively. The samples were later brought to SGS Philippines Inc. in Makati City, for laboratory analyses. The samples were analyzed for Biological Oxygen Demand (BOD), Oil and Grease, and Total Suspended Solids (TSS). The results of the field measurements and laboratory analyses are presented in Table 3.2.5. As can be discerned from the table, all the samples, except Sample No. 7 , taken from Zapote River in Pulang Lupa exceeded the DENR standard for the 5-day 20 o BOD level, which is 7 mg/L . Samples from San Dionisio (126 mg/L) and Las Piñas Rivers (81.5 mg/L) show the highest levels whereas the rest are just near the maximum. High BOD levels indicate that these river systems contain very high amounts of effluents with organic matter and thus, are polluted. This high demand depletes the dissolved oxygen needed to support plant and animal life. This explains why there are no higher forms of aquatic organism found in these river systems.

Based on the climatological normal at this station shown on Table 3.2.6 ., the climate in the area belongs to Type I of the Modified Corona’s Classification (Figure 3.2.14) . Two (2) pronounced seasons; the wet and dry characterize this type of climate. A very defined rainy season occurs in the months of June to September, the dry season on the other hand, is experienced during the months of the November to April. August is the wettest month, whereas April is the driest. Temperature The mean monthly temperature in the project areas is 28.0°C . The minimum monthly temperature is 24.8°C , occurring in January and February, while the maximum monthly temperature is experienced in April at 33.4°C . The warmest months are April to June with mean values ranging from 29.0°C to 29.8°C. Air Streams The principal air streams that significantly affect the study areas are the Northeast Monsoon, Southwest Monsoon, and the North Pacific Trades. The Northeast Monsoon predominates from October to May, while the Southwest Monsoon prevails during June to September. The North Pacific Trades is the southern portion of the North Pacific anticlyclone. Having passed over a vast expanse of the North Page 174 132 Pacific Ocean, this air stream is classified as a maritime tropical air mass. This air stream which is extremely warm, is generally dominant over the entire Philippines in April and early May. It commonly arrives in the country from an easterly direction but may come from any direction from northeast to southeast. Wind A wind rose diagram is a graphical presentation that depicts a bivariate frequency distribution table of wind speed and direction. It shows how much of the tome(expressed in percent) that a certain range of wind speed, certain wind direction, using the 16 points of the compass. In the study area, the nearest station is Port Area, Manila. The information contained in the Wind Rose Diagram attached as Appendix E, is taken from daily data for the period 1987 to 1996. Based on existing literature, the prevailing wind direction in Metro Manila is southwestward in the rainy season and eastward during the dry season. The average wind velocity is approximately 3 meters per second outside of the tropical cyclone season. Rainfall The highest average monthly rainfall in the project areas occurs during the month of August. With an average of 463.5 mm . The lowest monthly average rainfall in the area is during the month of February, with an average of 5.5 mm . The rainy season coincide with the occurrence of the Southwest Monsoon in the months of June to Page 175 133 September, the dry season on the other hand, is experienced in the months of November to April. Relative Humidity Relative humidity is controlled by the availability of moisture and air temperature. The relative humidity in the study areas is highest in the months of July to September. This coincides with the availability of moisture during these months. The months of December to February are relatively humid compared to those in March to April, due to the low temperatures brought about by the tail of the cold front during the northeast monsoon season. The transition months have intermediate values because of the average rainfall during these months. Major Cyclones The Philippines has an average cyclone passage of about 20 per year. In the study areas, the average frequency of cyclone passage is five (5) in every three (3) years. These cyclones have greater frequencies in the months of July, October, and November. 3.2.12 Air Quality and Noise Level 3.2.12.1 Ambient Air Quality Baseline air quality samplings for air pollutants such as Total Suspended Particulate (TSP), Sulfur Dioxide (SO 2 ), and Nitrogen dioxide (NO 2 ) were conducted along the proposed route. The data gathered shall be the basis in determining the changes of the Page 176 134 pollutant levels during the construction and operational phase of the project. Seven ( 7 ) ambient air quality sampling stations were identified to determine the present quality of air along the proposed route. Sampling Station 1 was set-up along the center median of Roxas Bouleverd, in front of Baclaran Church. At this station, four (4) 1- hr sampling intervals were conducted in two consecutive days. The 2 nd sampling station was established in front of the Uniwide Coastal Mall. Another station was put up along the grounds of La Huerta Elementary School. Sta. 4 was entrenched on a vacant lot along Dr. Santos Avenue in San Dionisio. The 5 th station was est ablished in Las Piñas Elementary School., whereas the 6 th station was set-up under the Coastal Road Flyover. The last sampling station was put up along the parking lot of St. Dominic Hospital in Bacoor, Cavite. In general a 1-hour air quality sampling was conducted for all the sampling stations. As clearly shown in the Table 3.2.7 , TSP levels at stations 1, 2, 5 and 6 exceed the DENR Standard. On the other hand, TSP concentrations of the rest are well within the standards. The results of the other pollution indicators are way below the set standard.

Based on the sampling carried out, the high noise levels recorded were due to the instantaneous peaks of passing trucks, buses, tricycles and all sorts of vehicles along the established sampling stations. The results of the said monitoring are summarized in Table 3.2.8 Page 178 136 Table 2.3.8 Observed Noise Level along the Proposed LRT Line 1 Extension Route Sampling Station Noise Levels in dB(A) Morning (05hrs-09hrs) Daytime (09hrs-18hrs) Evening (18hrs-22hrs) Nighttime (22hrs-05hrs DENR Standard 50 55 50 45 1 77 80 78 75 2 74 78 75 71 3 61 60 58 57 4 67 64 65 60 5 69 68 65 61 6 75 75 72 69 7 66 70 68 58 Sampling Stations Sta.1 In front of the Baclaran Sta.2 In front of Uniwide Coastal Mall Sta.3 School ground of La Huerta Elementary School, La Huerta, Paranaque City Sta.4 Vacant Lot along Dr. Santos Ave. ( near the site of the proposed C-5 Highway) Sta.5 Las Piñas Elementary School Sta.6 Under the Coastal Road Flyover Sta.7 Parking lot of St. Dominic Hospital, Bacoor, Cavite Noise Measurement at the Baclaran Church Vicinity Page 179 137 The purpose of the noise survey was to determine ambient noise level at the Baclaran Church and its entrance gate along the Redempotorist Road. A 1-minute average ambient noise level measurements were conducted during morning, early evening and afternoon period which coincides the expected AM and PM Peak periods, as well as Off-Peak operations of the proposed LRT Extension Project.

that could affect the Baclaran Church. The study limits the noise source from the steel wheel-rail interaction. The vibrations originated from the roughness in the rail and the wheel surfaces. Factors which influence the level of vibration are vehicle type, train, length, distance of the observer from the train, type of geologic medium, type of surface or underground structure supporting the track, and the track and the type of fastener. Results of predicted noise levels based on consu mptions using Peter’s model (See section 1.1 Methodology) is provided in Table 3.2.11. Table 3.2.11 Results of Predicted Noise Levels to be Generated by the LRT Train Distance from Railway For 34 kph train For 60 kph train 10 m 71.6 dB (A) 77.8 dB (A) 30 m 65.6 dB (A) 71.8 dB (A) 60 m 60.6 dB (A) 66.8 dB (A) For comparison, actual measurement of noise was conducted on board the existing LRT Line 1 from Monumento to Buendia Station. The observed noise level ranged from 70 to 94 dB(A) , the higher value of which, was due to the Page 192 150 train’s acceleration. The average level was at 85 dB(A) in a good condition rail track and a maximum of 94 dB(A) in a rough portion of the rail track. Prediction of noise levels combining the effects of present levels vis-à-vis the LRT train operation is discussed in Chapter 5. 3.3 Biological Environment 3.3.1 Flora There are two (2) major types of vegetation types identified in the area based. The flora community in the project area can be classified based on ocular survey into. These are the i) Natural Vegetation Type consist of residual Mangrove Forest and Grassland, and ii) Cultivated Vegetation Type , which is primarily composed of Built-up Vegetation. Natural Vegetation Type 3.3.1.1 Mangrove River Systems The mangal or bakawan, better known as mangroves today, is a unique ecosystem in the coastal areas of tropical regions. It is not only the habitat, of fishes, shrimps, shells, crabs, and other aquatic and terrestrial fauna, but it is also the haven of shrubs and trees useful to humans and to domestic animals (Buot, 1994). The most widespread use of mangrove areas, however, is its conversion into fishpond and human settlement areas which is deleterious to the organisms thriving in the said habitat. Mangrove deforestation and conversion results to the river pollution thus destroying the habitat, which makes it inhabitable for living organisms of economic value. Mangrove Plants Page 193 151 The Mangrove plants presently thriving in the area of study is shown in Table 3.3.1. The presence, absence and dominance of each species observed and identified were also noted. From the observations done in all four sites, there is relatively few mangrove species in the area and that the area is deforested. Houses built in the surrounding river are observed instead of a mangrove forest. Seedlings of mangrove trees just beside the La Huerta Elementary School near the proposed Ninoy Aquino Station was also observed, an indication that a mangrove rehabilitation programme is being implemented in the area. Based on local accounts, the rehabilitation was conducted by the DENR and now continued by a group from UP, Los Baños. Table 3.3.1 Mangrove Species Observed from the Collection Sites Collection Site/ Time collected Aegiceras sp. Bruguiera sp. Excoecaria sp. Prosopis vidaliana Proposed Ninoy Aquino Station (9:00A.M.) Dominant Present Present Present San Dionisio River (12:00NN) Dominant Present Present Present Golden Haven Station (1:00P.M.) Dominant Present Absent Absent Las Piñas River (8:15A.M.) Dominant Present Present Present Aromang Dagat Prosopis vidaliana, more commonly known as aromang dagat is a shrub or a small tree from 2-6 meters tall. It is an erect or sometimes sprawling plants with numerous strong, sharp spines. It is known to have been introduced in the country from Mexico. At present like in the project area, flourish in back beaches along and near tidal streams. 3.3.1.2 Grassland Page 194 152 The grasslands in the project area are commonly covered with two (2) species of grass. Saccharum spontaneum (talahib) and Imperata cylindtica (kogon). Although both these species are perfectly adaptive to wind dispersal, Saccharum, a much taller and coarser species with a clumping habit is more dominant and widespread. Other grass species present in the area include Paspalum conjugatum (laau-laau, T-grass), Minosa pudica (makahiya), Urena lobata (kulut- kulutan), Aneilema malabaricum (bangal), Axonopus compresus (carabao grass), Chrysopogon acicyulatus (amorsecos), and Pennisetum polystachyon (buntot pusa). Cultivated Vegetation Type Built-up Vegetation Built-up vegetation referred to here consist of ornamental plants found around the settled areas, as well as those along roadsides and medians. Some of the identified species are: Boungavilla spectabilis (Boungainvillea), Mussaenda doña aurora (Noña Aurora, Hibiscus rosa- sinensis (gumamela), Polyalthia longifolia (Indian tree), Plumeria obtuse (kalachuching puti), Canna indica (Bandera Española), Cordiaeum varriegatum (San Francisco), Acacia auriculiformis (Japanese acacia), Samanea saman (acacia), Acacia mangium (mangium), Erythrina variegate (dapdap), and Pterocarpus indicus subsp indicus (narra). 3.3.2. Fauna 3.3.3.2.1 Terrestrial Fauna Page 195 153 No in-depth study was conducted for the identification of wildlife fauna (terrestrial) since the alignment will traverse areas that are mostly built-up. Nevertheless field observation of some common birds and domesticated animals were noted, and are included in this section. The most commonly observed bird species are Passer montanus (tree sparrow), Cypselus subfurcatus (house swift), and Apus pacificus (white- rumped swift). Passer montanus is known to have been introduced around Manila from Japan or Formosa in the 1930’s . On the other hand, Apus pacificus can be found throughout the archipelago On migration from eastern Siberia to Australia. (John Eleuthere DuPont. Philippine Birds Monograph Series No. 2, 1971). Domesticated animals noticed include common house cats, dogs, and chickens. 3.3.2.2 Aquatic Fauna Physicochemical Characteristics of the River Systems Observations on the present physicochemical characteristics of the river systems of Las Piñas and Parañaque were conducted on July 1999. The river is relatively shallow and the color of the water from the surface is black as the color of the sediments. They exhibit foul odor as reflected also in the areas of study due to domestic and industrial wastes accumulated in the river system. Table. 3.3.2 Physicochemical Characteristics of the Rivers Taversed by the Alignment Collection Site/ Time collected Surface water Temp (C \0c Salinity (ppt) Water clarity (cm) Proposed Ninoy 37 4 45 Page 196 154 Aquino Station (9:00AM) San Dionisio River (12:00NN) 38 2 37 Golden Haven Cemetery Station (1:00PM) 27 2 35 Las Piñas River (8:15AM) 36 4 35 Biological Component of the River Pelagic Table 3.3.3 shows the biological components observed from the rivers. Six (6) species of phytoplankton were identified so far, and three (3) genera of zooplankton. The nekton observed, and identified so far are two (2) species of guppy or the mosquito fish and they are relatively abundant and dominant. Abundance of this type of organism is an indicator of a polluted habitat adding the deformed morphology of some species of phytoplankton. Existence of these kind of organisms may be due to the wastes coming from the drainage of several sources and the anthropogenic wastes coming straight from the houses built within the river system.. The pollutants draining and diluting the river may change the rivers’ water quality that is harmful to organisms and thus change the composition of the organisms. Table 3.3.3 Plankton and Nekton Observed from the Collection Sites Phytoplankton Zooplankton Nekton Ceratium sp. Cladocera Guppy Ceratium contortum Copepoda Chaetophora sp. Rotifera Oscillatoria sp Phormidium sp. Anabeana Page 197 155 Benthic The observed benthic composition of the mangrove river system of the proposed Ninoy Aquino Terminal, san Dionisio and the site at Golden Haven cemetery were to be almost the same. Benthos can be described as sandy to blackish- mud with no traces live macro-invertebrates and microorganisms. Thrown garbage from the households settled at the bottom and adds up to the heavy metal accumulation and organopollutants. Resident macrofauna from mid-littoral zone were not observed. Empty shells of young Terebralia sulcatus were present in mangrove banks. Not even a single gastropod was observed alive even those gastropods that reside in mangrove trees. The absence of gastropods threatens the system since they act as useful in monitoring marine water pollution ( Walsh, et al., 1995 ). With the composition of the three mangrove rivers systems, depletion of macroinvertebrates takes place. 3.4 Socio-Economic Environment 3.4.1 The National Capital Region or Metropolitan Manila: The Host Region Metropolitan Manila is the country’s primary, economic, social and cultural center. It is now composed of eleven (11) cities and six (6) Page 198 156 municipalities, covering a total land area of 635 square kilometers. Being strategically located at the mid-section of the Luzon Island, it links Luzon’s northern and southern provinces. Based on its 1995 population of 9.5 million and an annual growth rate of 3.3% its current population is computed to be 10,765,115 . It is a very crowded area with a population density of 14,800 persons per square kilometers. Using 1995 as base year, the NCR population is expected to double in 21 years . Total labor force of Metro Manila, as of January 1999, is 5.561 million with an employment rate of 85% . Metro Manila evolved as a result of the rapid urbanization of the City of manila which was the dominant commercial business district of the country. Intense economic activities causing high in-migration spurred development of adjacent areas like Makati city, Cubao in Quezon City, and Ortigas Center in Pasig City. In the 1980s, development reached the peripheries such as Novaliches, the cities of Marikina, Muntinlupa, Las Piñas, and several towns in Cavite, Laguna and Bulacan. Population grew very fast in the 1960s and 1970s with growth rates at 4.9% and 4.1%, respectively. Metro Manila’s predominant land use is residential with 65% of its area devoted to housing development. Commercial and industrial areas account for 5% and 3% respectively. Agricultural lands which are mostly found in the fringes and parts of the inner core, comprise 14%. Open spaces, largely located in Quezon City and Las Piñas represent 2.5%. Page 199 157 The Metro Manila Development Plan 1996- 2016 characterizes the regions’ land use trends as follows: · Increasing density and size of squatter settlements · Development of medium-scale residential subdivisions in the peripheries of the inner and intermediate cores with low cost housing occurring at the outer core · Proliferation of major commercial centers along EDSA and other major roads · Infilling of other urban areas with high-density housing. For the past 20 years , development in Metro Manila has been towards Parañaque, Las Piñas and Muntinlupa in the south, to Novaliches in the north, and to Marikina Valley in the east. Strongest growth was noted in the northeast (Quezon City) and in the south towards Muntinlupa. The same trends are predicted to continue with growth extending to neighboring towns of adjacent provinces. Not to be overlooked however, are the industrial developments in the municipality of Valenzuela, administratively falling under the Province of Bulacan, but also part of the National Capital Region. It is significant for this study because of its proximity to Monumento in Kalookan City where the LRT Line 1 starts. 3.4.2 Cavite: The Host Province in the South End 1 The Province of Cavite since the 1980s has been transformed from a largely agricultural area into a developing zone of industrialization, tourism, and commercial activities. These changes are attributed to the government’s program to direct 1 1 This report includes a discussion on Cavite Province because the southern end of the proposed project reaches up to the Municipality of Bacoor, one of the major entry points to the province and the Calabarzon area Page 200 158 developments outside of Metro Manila towards CALABARZON (Cavite, Laguna, Batangas, Rizal and Quezon). Cavite’s proximity to Metro Manila had made it a logical expansion area for urbanization, business and housing development. It is less than 30 minutes away from the Ninoy Aquino International Airport. It has since joined the league of 20 first class provinces in the country with an annual income of P300 million . It has ranked the highest in terms of foreign investments (354 million) in Region IV and second to Laguna in local investments (P633 million). In 1995, Cavite already had fifteen (15) fully operational industrial estates with six more in the planning stage. The province at that time already listed about 500 firms including the 200 firms within the Cavite Economic Zone. These companies with total capitalization reaching P26 billion employed slightly less than 80,000 workers. Companies in the drawing board are expected to bring in additional capitalization of P17 billion. In the same period, besides the seven (7) DOTC-accredited resort hotels, five (5) world class golf courses with residential estates have been completed. Cavite is also a preferred expansion site for tertiary educational institutions, which were originally based only in Manila or Quezon City. As of 1995 , province has recorded 21 and 8 private and public colleges, technical and vocational schools, respectively, that have set up branches in various parts of Cavite. Among the better known institutions are: De La Salle University (including its medical school), Philippine Christian University, Technological University of the Philippines, AMA Computer College, and Systems Technology Institute (STI). Cavite also hosts Page 201 159 seven (7) training centers including those of the Development Academy of the Philippines and International Institute for Rural Reconstruction. Agriculture Besides employment in industrial and tourism estates and economic zones, the other major source of livelihood in the province are farming, commercial fishing and fishpond operations. Rice, coffee, banana, pineapple and other fruits comprise the major agricultural crops. Seventy- five percent (75%) of Cavite’s 106,079 hectares remain committed to agricultural activities. As of 1995, 477 hectares are devoted to bangus (milkfish) and prawn culture. About 20,000 fisherfolks are engaged in commercial and non-commercial fishing. Business & Industry Five years ago, Cavite recorded a total of 40,523 business establishments aside from the numerous business locators in the industrial estates and economic zones. Retail/wholesale outfits, followed by banking and finance companies, and manufacturing establishments dominated the list. In 1994, total capitalization reached P2.6billion . Aside from commercial businesses, the province hosts 311 cottage industries with a capitalization of P23 million . These cottage industries are involved in food processing, garments, metal crafts, and handicrafts provided employment to about 2,000 persons. Housing Facilities Page 202 160 As of 1993, at least 3,000 hectares of the provincial land area have been used for residential subdivisions and socialized housing projects to accommodate the spill-over population from Metro Manila. Among the host municipalities with biggest areas for housing development projects are Bacoor, Dasmariñas, and Tanza. Recently, residential subdivisions have also arisen in Tagaytay City, Trece Martires City, Silang, Gen. Mariano Alvarez, and Gen. Trias. These are also the same areas wherein the industrial and tourism developments have been recently occurring. 3.4.3 The Host Cities & Municipalities The City of Parañaque: Towards Greater Heights Parañaque has attained cityhood only recently but it aims to become a self-sustaining and lead city within the next few years. It is one of the more urbanized areas of Metro Manila with a population of 446,145 growing yearly at the rate of 4.6%. With a land area of 4,657 hectares (including the reclamation area), it is the third largest within the National Capital Region. Parañaque City’s renewed potential for commercial and residential development comes from the reclamation effort along Manila Bay under the Boulevard 2000 Project. When completed, Parañaque’s land area shall have increased by 18% or 827 hectares. Barangay Baclaran remains the main Central Business District (CBD) of Parañaque. Areas along Ninoy Aquino Avenue and A. Santos Avenues (or Sucat Road) are emerging commercial and business centers. Main streets within Barangay BF Homes, Better Living Subdivision and Page 203 161 Multinational Village have also witnessed the mushrooming of small to medium-scale business establishments. During the Ramos Administration, expectations have been built up towards high-end mixed-use development in the reclamation area along Manila Bay. A few years hence, the Uniwide Coastal Mall and several skyscrapers arose, along with upscale residential subdivisions in the much-touted Asia World City. Yet, business has yet to pick up in this site. In 1997 , registered business and commercial establishments reached a total of 12,818 . Majority (53%) of the establishments belongs to the wholesale and retail sector. More than one-fifth (22%) are service contractors. The rest are eateries/restaurants ( 7%), manufacturing firms (4%), and exporters (2%). Twelve percent (12%) were grouped as various establishments. Industrial firms are concentrated along the South Superhighway. These are mostly electronics and garments factories. In 1994, these totaled about 247 with aggregate investments of P15 billion . With only 13 hectares devoted to agriculture, activities in this sector are very minimal. Fishing is confined along the coastal areas of Manila Bay. Prior to intense housing developments in the southern part Metro Manila, District II of Parañaque was among the first areas to be developed into residential subdivisions in the 1970s up to the early 1980s. On the other hand, District I represents Parañaque’s traditional residential communities. Like most areas of Metro Manila, Parañaque has not been spared of a big share of depressed communities. The city government has pinpointed 168 blighted areas. Page 204 162 The City of Las Piñas: The Gateway to Calabarzon 2 Geographically, Las Pinas straddles the gateways to CALABARZON. One entry point at the eastern part of the city leads to Laguna and Batangas via the South Superhighway. The other gate is the Coastal Road to the west along Manila Bay that leads to Cavite and southward to Batangas. These two gateways are linked by the Alabang-Zapote Road. Two other major arteries, Sucat Road and Calle Real (now the Quirino Avenue) which combines with the Coastal Road complete the triangle that defines Las Piñas’ strategic geographic function south of Metro Manila. Within this triangle lies 3,000 hectares of prime urban land going through consistent development into a first class city. Las Piñas is mainly a residential area for Metro Manila workers and businessmen. Almost half of its land area is devoted to medium-density residential subdivisions interspersed by high-density communities. The latter are generally found in blighted areas in the city’s northern fringes facing the coastline. Low-density residential areas comprise a small portion in the eastern side of the city. Unlike the industrializing sites in CALABARZON area, Las Piñas houses mostly small-medium enterprises (SMEs) as most of its big factories have relocated outwards to the CALABARZON area. Ninety percent (90%) of its total 10,000 business establishments are SMEs, which are touted as the entrepreneurship base of city’s future role as the “Southgate of Metro Manila.” 2 This section is largely based on the Comprehensive Development Plan of Las Piñas, Volume 2, March, 1997. Page 205 163 Most of the commercial establishments and large shopping malls are located along the Alabang-Zapote Road. These establishments include Shoemart (SM) South Mall, Manuela Metropolis and Filinvest City. Two years ago, the city government has declared the old Calle Real from the Parañaque boundary up to Zapote bridge as the “Las Piñas Historical Corridor,” a Spanish type tourist destination. Restoration of buildings and landmarks has since been undertaken in this part of the city. Very little agricultural activity is undertaken in residual farmlands, salt beds and fishponds, which comprise a total of three percent (3%) of the total land area of Las Piñas. Vacant or open space represents 31% of Las Piñas. This is however on the decline due to conversion to residential and other uses. As of 1995 , Las Piñas recorded a population of 413,086 . With an average growth rate of 6.39%, the city will have a populace of 528,011 by year 2000 . The Municipality of Bacoor 3 Like Parañaque and Las Piñas, the municipality of Bacoor is also a catchment area for overspill population from Metro Manila. It currently has a population of 250,821 persons and 52,594 households in its 73 all-urban barangays. Growth rates since the 1980s ranged from 9-11% annually compared to 5-7% in the 1970s. Authorities say that development of residential subdivisions was partly spurred by the opening of the Manila-Cavite Coastal Road in the 1980s . Increases in population have been attributed to in-migration of families who were able to buy residential properties from the various housing 3 Data for this section were largely based on the Socio-economic Profile of the Municipality of Bacoor and NSO. Page 206 164 projects, and those who opted to move into urban environs to improve their access to Metro Manila-based job opportunities. Trade, commerce and service sectors constitute the primary sources of income for the Bacoor population. These are mostly wholesale, retail (sari-sari stores) and restaurant establishments. Business establishments are mostly concentrated in Zapote, Panapaan, Mabolo and Talaba. Other income earners are small-scale manufacturing, cottage industries, and fishing which includes oyster mussel culture. Agriculture experienced a rapid decline due to land conversion for subdivisions. In 1995, registered business establishments reached a total of 3,690. This number does not include establishments within the Shoemart (SM)- Bacoor Commercial Complex and other commercial buildings that recently sprouted along Aguinaldo Highway. Bacoor also has a total of 94 schools, all types, public and private. Official documents cite that rapid urbanization has definitely led to population increases which consequently lead to bigger demand for urban services including a more efficient mass transport system. Current problems faced by the municipality are unemployment, traffic congestion due to narrow streets, low-cost housing shortage, unsanitary living conditions, and flooding in low-lying areas including the Poblacion. 3.4.4 The Direct Impact Areas This study concentrated on direct impact areas defined as follows: Page 207 165 · Where houses and properties would be hit (i.e. 10 meter ROW tract) 4 ; · Where necessary project-related road widening would be done; · Where land for stations would be acquired; · Where establishments and vendors would be physically and economically affected; · Where socio-religious centers and landmarks would be potentially disturbed. 3.4.5 Affected Population Groups Table 3.4.1 shows the affected population groups by type and by area.

It is bounded by the Baclaran River in the east, Pasay City on the north edge, Manila Bay on the west side and Barangay Tambo in the south. Baclaran is historically known for the Wednesday Novenas at the Mother of Perpetual Help National Shrine at the Redemptorist Church which regularly bring in some 10,000 people from different parts of the country. It later became a center for trade and commerce, being the melting pot of people bound for the other areas of Parañaque, Las Piñas City, Cavite and other Southern Luzon provinces. As stated in the community’s socio-economic profile (1996), Baclaran has 81 major business establishments, composed of shopping malls, restaurants, commercial banks, supermarkets, wet markets, drug stores, theaters, and a gasoline station. Not to mention the thousands of small 7 See pertinent Parañaque-related tables for more details. Page 211 169 businesses in the different shopping centers along Redemptorist Rd., Quirino Ave., and other major thoroughfares. (See Table 3.4.2) Table 3.4.2 Number of Business Establishments According to Type of Business Type of Business Number Dry goods market/Shopping centers 23 Food chains/Restaurants 19 Commercial banks 18 Supermarkets 5 Wet Markets 5 Drug Stores 5 Theaters 5 Gasoline station 1 Total 81 In Redemptorist Road alone, there are twenty-four (24) commercial and mixed commercial-residential establishments. ¾ South side of Redemptorist Road 1.

Berma Center (Shopping center/theater) 19. Besta Center Potentially Affected Groups Building Owners At present, Baclaran is going through a phase of modernization, most especially along the busy streets of Redemptorist and Quirino. Very noticeable changes are the recent renovation of Berma Shopping Center/Theater and FUAGVMI Trade Center. Other obvious developments are the newly constructed 3-storey McDonald’s restaurant building at the corner of the north side of Redemptorist Rd. and Quirino Ave., and Rofer Land at the South side, which is on the initial stages of construction. Segundina Market located at the south side of Redemptorist is also currently being renovated. These said establishments, according to Bryg. Captain Rolando C. Cailles, contribute heavily to Barangay Baclaran’s yearly income in the form of real property taxes, business taxes, etc. Tenant Business Owners Two to three hundred small and big businesses currently operate in the area. McDonald’s, Jollibee, Dunkin Donuts, Uniwide Family Store, and Page 213 171 PCI Bank are among the big businesses situated along the proposed alignment. Small-to-medium-scale tenant business owners are engaged in the retail of clothing/apparel and eatery businesses. Around two hundred fifty business owners of these types abound in the shopping centers mentioned earlier. (This number may have increased, considering that during the survey period, the 3-storey FUAGVMI Trade Center was still in the latter phase of renovation.) Vendors According to Ms. Norma Sandoval , President of the Federation of Baclaran Vendors, there are about five (5) thousand fixed-stall and ambulant vendors in Barangay Baclaran. Along redemptorist Road alone, there are 120 fixed stall vendors while another three to five hundered of the ambulant type, abound in this busy street. Fixed-stall vendors are usually those with a 2-4 square-meter tent-like business posts on the sidewalks of Redemptorist Rd. Ambulant vendors, on the other hand, are those that stay on the unoccupied parts of the pavement and a large portion of the street usually their mobile carts (kariton) or oversized baskets or bilaos, where they display their goods. Profile of Potentially Affected Groups Business Establishments 8 Length of Stay in Baclaran . Most of the buildings in Baclaran were built between the 1960s and the 1970s. A few were either constructed or renovated very recently like in the case of Berma Shopping Mall and Fuagvmi Shopping Center others currently being rebuilt. It may also be 8 See pertinent tables on Business Establishments for more details Page 214 172 interesting to note that Besta Shopping Mart, the oldest building along Redemptorist, was built in the 1920s. Out of the 66 building and business owners interviewed, 73% are newcomers in Baclaran. They started business operations only in the 1990s. Around 15% began in the 1970s. Space Occupied. Majority of the tenant business owners occupy below 20 square meters of commercial space. Some even make do with two square meters or less. Type of Merchandize/Business. About 65% of the business owners in Baclaran are engaged in the apparel trade. Items sold range from t-shirts, pants, blouses, skirts and other ready-to-wear items. The remaining 32.5% of the respondents are in the restaurant/eatery business. Vendors 9 Length of Stay in Baclaran. Unlike the established big and small business enterprises, the vendors started out early in Baclaran. Most of them (73%) came in the 1960s up to the 1980s . Space Occupied . In contrast to the bigger traders in the area, most fixed- stall vendors have to make do with a one-or-two-square-meter makeshift business posts, and even worse for ambulant vendors where their mobile carts and native bilaos measure only to about one square meter. Type of Merchandize/Business . Goods range from apparel/clothing, various accessories, footwear to religious items, candles and fresh 9 See pertinent tables on Vendors for more details. Page 215 173 flowers, etc. About 45% sell various types of clothes (t-shirts, pants,shorts,baby dresses, etc.), 21%, accessories such bags, hair clips, wallets, and 13% hopes to earn a living from selling religious items, candles and fresh flowers to church-goers. Why Redemptorist? The results of the perception survey conducted reveal various reasons why so many traders pick this area for business. Majority of the respondents (61%) expressed that Redemptorist Road is the center of Baclaran and that it is in this particular area where business is flourishing or as they say “malakas and kita”. Source of Capital Almost 70% of the respondents say that their primary source of capital is in the form of loans, either from private individuals or various lending institutions. Sixty-two percent (62%) of the vendor- respondents stated that they have to turn to usurious loans the vendor- respondents stated. (“5-6”) for their revolving capital. The lucky ones started business with their own savings (18%) while around 6% get their goods on a consignment basis. 86% of the vendor-respondents also said that their loan payments are collected on a daily basis, and that they should earn an extra P200 daily to pay for their principal and interest. “Taxes”. Taxes or fees charged come in various forms. The barangay tax or “buwis sa barangay” ranges from two to six pesos daily while the municipal tax or “buwis sa munisipyo” varies from two to ten pesos also collected on a daily basis. These “taxes” are collectively known as ALKABALA . Some fixed stall vendors also say that thay purposely do not open on Tuesday and Thursday because it is during these days when corrupt policemen usually drop by to collect what the vendors call “tong” or “Lagay”. Page 216 174 Income. Average daily income ranges from P100 to P600 . Sixty-three percent (63%) of the respondent mentioned that they earn P300 and below, 9% say around P400 to P600 while the rest refuse to answer the question. Eighty-five percent (85%) of those interviewed also added that their small business in Baclaran is their only source of income/livelihood. Level of Organization. From among the vendors interviewed, 81% are members of the different member-organizations under the Federation of Baclaran Vendors, headed by Ms. Norma Sandoval. Ms. Sandoval also cited that there are thirty member-organizations under the said federation. One of the vendor-organizations in Redemptorist Road mentioned is the Redemptorist Religious Sidewalk Vendors, Religoius & Dry Goods Association, Inc. The vendor-members also said that their federation has nothing against the LRT project except that they cannot agree to the proposal that the LRT Line 1 extension pass through Redemptorist Road. Perceptions About the Project Business Establishments 10 More than a hundred building/business owners were approached during the survey but unfortunately about 50% of them refused to be interviewed. The perception survey reveals that only 58% of the building/business owners are aware about the project. When asked if they agree to the project, 85% answered in the affirmative. But when further asked regarding the proposed Redemptorist alignment, the answer was a categorical no (85%). 10 See pertinent tables on Establishments for more details Page 217 175 The reasons given for a low acceptability are as follows: perceived decline in business as in the case of Carriedo and Avenida (mamamatay ang mga negosyo & matutulad ang Baclaran sa Carrriedo at Avenida); disturbance to church-goers and to the solemn atmosphere of Redemptorist Church (apektado and Simbahan); Vehicular and pedestrian traffic congestion (sisikip and daan); and loss of income for public utility vehicle drivers and operators. When asked about what the project must do to somehow address the negative impacts of the project, the most common responses were: “Anywhere but Redemptorist Road” and “Consider other alternative routes such as Quirino Ave., EDSA-Roxas Blvd., and Airport Rd.”, expressed in the native tongue as Huwag sa Redemptorist idaan and LRT and Sa Quirino Ave./EDSA/Roxas Blvd. /Airport Rd. idaan. As far as perceived impacts are concerned, almost 88% of the respondents said they could see how they could benefit from the project and that they could not mention even one good effect to them and the community, as a whole. About 9% though, expressed that this could ease the traffic problem and that this would be favorable for commuters. Vendors 11 As gleaned from the perception survey, majority (81%) already knows about the project. But when asked it they agree to and accept the project, 85% said no. 11 See pertinent tables on Vendors for more details. Page 218 176 Reasons enumerated for non-acceptance are: loss of costumers and significant decrease in earnings and worse, closure of businesses (mawawalan ng costumers, kita, o hanapbuhay), severe traffic congestion, and destruction of the divine and solemn atmosphere of Baclaran church (masisira/magiging maingay sa simbahan). Some even expressed their fears of Baclaran being like the virtually dead Avenida and Carriedo, which prior to the LRT Line 1 construction was one of the major business centers in Metro Manila. When asked about what the project proponent must do to somehow address the negative impacts of the project, the vendor-respondents gave answers similar to those of the tenant business owners such as “Huwag sa Redemptorist idaan ang LRT,” and “ Ideretso sa QuirinoAve.” Some even strongly stated that they would be better off without the LRT Line 1 Extension Project. Like in the case of business owners, the 95% of the vendor-respondents also think that they are bound to lose more rather than benefit from this project . When asked about the possible positive impacts of the project all they could say was “none.” Only 2% of them said that the project could improve the traffic situation and somehow lessen pollution caused by vehicular traffic. Section of Coastal Road, Barangay Tambo 12 Uniwide Sales Coastal Mall is just one of the several commercial centers in different parts of Metro Manila established by Uniwide Holdings Inc. owned by Mr. Jimmy Gao. The mall is composed of two buildings and a 12 See pertinent tables on US Coastal Mall Establishments for more details Page 219 177 big parking area. It started its operations in 1996 but their performance up to this been way below their expectations. The mall is situated at the west side of Coastal Road in Barangay Tambo, Parañaque City. The structure, which occupies 5.6 hectares, stands on a 10-hectare land leased from the Public Estates Authority (PEA). According to Engr. Tolentino, Uniwide sales Coastal Mall building administrator, only 50 of the 830 commercial spaces available are currently under lease contracts by medium to large business enterprises. The LRT Line 1 Extension is certainly a welcome boost for business and trade in this area. Commercial banks such as, the Bank of the Philippine Islands, Equitable Bank, Philippine Bank of Commerce and Ecology Bank are among the big business groups in the center. The more popular food chains such as Jollibee, Mc Donalds, Shakeys and Greenwhich Pizza Parlors also maintain big commercial spaces at the ground floor. About 25 small traders occupying temporary mini business stalls stand in the corridors near the mall’s entrances. As culled from the survey, all the seventeen (17) business owners/managers interviewed are new tenants. Eleven out of the seventeen (58%) respondents started in 1998 while the rest only came in this year. As mentioned earlier, there are fifty (50) small to big businesses currently operating in the center composed of restaurants, shoe stores, apparel shops, commercial banks, jewelry stores, bookstores, and amusement centers shown in Table 3.4.3. Page 220 178 Table 3.4.3 Number of Business Establishments According to Type of Business/Merchandize Type of Business/Merchandize Number Food chains/restaurants 8 Jewelry stores 7 Footwear 6 Apparel 5 Commercial banks 4 Appliances, Furniture & Accessories Center 3 Bookstores 2 Amusement centers 2 Optical shops 2 Music Store 2 Photo shop 2 Others 7 Total 50 The perception survey reveals that 58% already know about the proposed project. Majority (95%) also said that they are in favor of the project. Reasons given for high project acceptability are: there would be more customers because of the proposed location of an LRT station at the intersection of the proposed location of an LRT station at the intersection of Coastal and MIA Roads, less traffic and fast transport system. The respondents (63%) however raised concern for serious traffic problems especially during the construction phase and they suggested that re-routing be considered to address this problem. Barangay La Huerta Riverbank Informal Settlers 1314 13 Two respondent-households each from M. Rodriguez and In front of Iglesia ni Kristo indicated that they are house-and lot-owners. Their documented properties may have only encroached on government land. 14 See pertinent La Huerta-related tables for more details. Page 221 179 These informal settler communities are located on the fringes of the south bank of the Parañaque River. With the help of local interviewers, the Public Participation Team was able to group them according to their specific locations, namely: M. Rodriguez, opposite Iglesia ni Kristo Church, and Tabon. The informal settlers in M. Rodriguez comprise the cluster of thirty five (35) households at the mouth of the Parañaque River where it joins Manila Bay. Dwellings are mostly one-room affair shanties on stilts. The next cluster comprises forty-eight (48) households opposite the Iglesia ni Kristo Church up to the Sto. Niño Bridge. The structures made of light materials and galvanized iron sheets are poorly constructed 2-3 level extensions of better made houses. They are accessible through narrow alleys from the barangay proper. Interviews revealed that majority of those living here are actually second generation families of original middle to low income La Huerta residents. Also on the south bank of Parañaque River but on the east side of Sto. Niño Bridge is the Tabon cluster, composed of eleven (11) households, which is located beside the La Huerta Barangay Hall and behind the La Huerta Elementary School. Respondents said that thay were relocated here during the construction of the Coastal Road. The quick census identified a total of seventy-one (71) dwellings occupied by ninety-four (94) households. Twelve percent (12%) are women-headed households. Majority (75%) is a single household per dwelling families. Fourteen percent (14%) indicated that they share their residence with another family. Ten percent (10%) share their abodes with two other families. Page 222 180 Average family size is 4.5. Total affected population is four hundred twenty-five (425) persons. Residence History & Status of Occupancy. The majority respondents in M. Rodriguez and those located in front of Iglesia ni Kristo indicated that they are standing on public land. In Tabon, almost 50% admitted that they are occupying public lands. The other half said that their homelots are privately owned and that they are occupying it for free. For Iglesia ni Kristo cluster, majority (71%) own their dwellings. Six percents (6%) are house renters. Two percents (2%) are house and lot renters and 17% are either dwelling sharers or rent-free dwelling occupants. In Tabon, three (3) households are house owners on public land; six (6) households are house owners in private land. Two (2) households are occupying dwellings for free. In M. Rodriguez, majority (54%) are house renters; 34% are house owners; and 5% occupy rent-free dwellings. The rest claim to be house- and-lot-owners. Residence history date corroborate that majority in Tabos and Iglesia ni Kristo are long-termers. M. Rodriguez has relatively more new settlers. At least 11 households that they came from Freedom Island and other parts of La Huerta where clearing of informal settlers have previously occurred. Also when asked how they settled in their current place of residence, more than half from both Tabon and Iglesia ni Kristo clusters said that they were actually born there. Page 223 181 Age. Majority of the household 64% of husbands, and 73% of the wives heads are young with ages ranging from 16 to 44 years old. About 5% of the households’ heads are senior citizens. The rest are 45 to 59 years old. Educational Attainment. Education levels for both female and male household heads are low. Slightly more than 20% finished high school. Not more than 10% finished college or vocational degrees. Household Income. Based on the NSO 1995 poverty figures, 20% of the respondent families fall below the food threshold of P41,850 yearly for a family of six. Forty-five percent (45%) f all below the poverty line which is P67,872 annually for a family of six. Using the national poverty threshold figure of the National Anti-Poverty Commission which is P132,000 yearly for a family of six (equivalent to P11,000 income per month), approximately 80% of the families are classified as poor. Sources of Income. The male adult household heads earn incomes from: sea-based activities such as fishing, mussel-gathering, wharf porters, fish- bidding (40%) ; as skilled workers such as drivers, carpenters, musicians (20%) ; as unskilled labor (11%) . Others (12%) are rank-and-file government or private sector employees. Some (7.5%) have their own small-scale business such as sari0sari store owners, market stall holders, making and selling sweets and merienda (snack) items. 2.5% are overseas contract workers. 7.5% are jobless. The women are mostly housewives with no gainful source of income (74%) . Some (15%) are self-employed as fish and mussel vendors and bidders, sidewalk vendors, beauticians.

Almost half (49%) of the respondents who are gainfully employed, work in La Huerta and other nearby barangays of Parañaque, The others work in neighboring towns (Las Piñas, Muntinlupa), and within Metro Manila such as Manila, Makati City, Quezon City and Navotas. One said he works in Laguna. Community Cohesion. From the interviews, all the three clusters exhibited very slight sense of community cohesion. This was expressed mainly through community leaders that they recognize. The Barangay Captain topped the list of ten leaders mentioned. Perception about the Proposed Project Majority (64%) of the respondent-households are familiar with the project. Scoping meetings, interviews, LRT project personnel, and neighbors are among their sources of information. Initially when asked, in general if they agree to the project, 30% said yes. 50% said no. However, to the question, if directly affected, would they agree to the project, the affirmative answers decreased to 3%. Those who said no decreased to 17%. Conditional answers increased to 71%. Page 225 183 Among the conditions given are: decent in-city relocation package (51%), fair negotiations (15%), disturbance and damage compensation/financial assistance (13%), and execution of a written agreement (6%). 3.4.6.2 Las Piñas 15 Informal Settlers in Abuhan, Barangay Manuyo 1 Abuhan is accessible through maze of narrow alleys from a relocation site called Poultri Compound. Some respondents said that Abuhan is part of the Villar- Aguilar property, which is planned to be transformed into a commercial center. Other said it is public land. The Abuhan Community is located on a strip of land along one of the creeks in Manuyo 1. It is visible from within the Golden Haven Memorial Park. Within the 30-meter width, the Public Participation Team identified eighteen (18) households but only fifteen (15) were available for interviews. Dwellings are connected one-room structures built from light materials and GI sheets. Twelve (12) households live in their own one-room structures. Three families share their dwelling with one other household. Average household size is 4.4 . Computed affected population is sixty-six (66). Ages of female and household heads range from 20 to 54 years old. Two (2) households were headed by senior citizens. Three (3) households are headed by women. Of the twenty-eight (28) household heads, thirteen (13) finished high school. Seven (7) are college or vocational course graduates. The rest finished elementary school. 15 See pertinent Las Piñas-related tables for more details. Page 226 184 The husbands are all gainfully employed as skilled and unskilled workers, except for two (2) who gave no answer. Eleven (11) of the female adult heads are housewives with no gainful employment. The four (4) get their income from doing laundry, working as a factory worker, as a maid, and from a small sari-sari store. Based on the NSO 1995 poverty statistics, six households fall below the poverty line. Other revealed their incomes to be within the range of P70,000 to slightly over P200,000 per year. Five (5) households joined the community in the 1990s. The rest started living there in the 1980s and earlier. Six (6) household heads said they were born in that community.

Thirteen (13) families or 87% said that hay belong to a neighborhood association. The rest indicated no membership. High community cohesion could be attributed to community organizing efforts of the Urban Poor Affairs Office to prepare the community for eventual relocation. Perception about the Project All the respondents have heard about the proposed project. Accordingly, they were iformed by the Las Piñas Urban Poor Affairs Office that they will be affected by the project and that they were informed that they will be relocated. Most of them have no objections to the project for as long as they will b properly relocated. A minority indicated that employment opportunities and financial assistance from the Project Proponents can make life easier for them. Page 227 185 The ABC Community, Pulang Lupa 1 This is an old residential/commercial community located on the north approach of the Real Bridge from Zapote. Affected are a mix of modest private residential and commercial properties and low-income renters of small homelots and dwellings, which are not easily visible from the roadside. Within the 30-meter width, the Team identified thirty-four (34) households. Average household size is 4.9. Total affected population is about 167. Affected private properties are the ABC/Lovers’ Disco, an automotive shop and a bus terminal. On the south approach of the Real Bridges is the Las Piñas Elementary School. Sources of Income. Majority of the male adult heads are of skilled and unskilled workers and those with small scale businesses. Two thirds of the women are housewives.

The other half indicated incomes ranging from P70,000 to P200,000 yearly. Residence History. Almost half are old timers in the community having been there between the 1930s and the 1980s. The rest came in the 1990s. Community Cohesion. Only 12% indicated membership to a community organization. The rest are not organized in any way. Perceptions about the Project Page 228 186 Slightly more than half has heard about the project but their information is on a hearsay basis. When asked in general if they agree to the project, 62% said yes. Less than 29% said no. The rest gave no answer. However, to the question “if directly affected would you agree to the project?” only 3% categorically said yes. Twenty-nine percent (29%) said no. Sixty-five (65%) gave conditional answers.

Tramo Street., Pulang Lupa 1 This community of NHA lot awardees and applicants is found on the north approach of Tramo Bridge along Tramo, St in Barangay Pulang 1. Within the 30- meter width, the Team identified 50 households. Average household size is 4.12 . Total affected population is 206. Looking at the concrete one to three level structures, this section of Tramo St. has metamorphosed from an informal settlers’ depressed area into an improved, though still congested, residential community. Ten families are single households to one dwelling. Six (6) families share their house with another family. Twenty (20) families are three households in one dwelling. Fifteen (15) respondents said that they share their house with four (4) other families. Page 229 187 Educational Attainment.

Next to Abuhan, the community displays high level of cohesion. They have shown substantial participation in scoping meetings. The survey data also indicate that 56% of the households are organized. NHA may have been instrumental in organizing them. One of the recognized leaders is Mr. Boy dela Cruz. Perceptions about the Project. Majority of the respondents (82%) have heard about the project. Their sources of information are municipal and barangay officials, the neighborhood association, EIA Team. Several heard it from the grapevine. They are also aware that their houses may be directly affected and that the proposed project is likely to push through. Page 230 188 When asked if they agree to the project even if their properties are affected, 12% categorically said no. Eight percent (80%) gave conditional answers. Eight percent (8%) abstained. Conditions to make them agree to the project are: decent relocation package (43%) , in-city relocation (12%) , fair compensation (31%) and preferential employment (10%). Informal Settlers in Daang Kariton/Calle 5/Gabriel Compound in Barangay Pulang Lupa 1 This community is located behind ABC and along the north bank of the creek. This place is called by different names: Daang Kariton or Calle 5 or Gabriel Compound. It is accessible through a narrow alley from the Petron gasoline station along Real Street. This big informal settlers community is not visible from the road. Part of it can be seen from the Real Bridge. The occupied area is public land. Entry into this place is difficult without a guide familiar to the maze of alleys and footpaths. It is a very congested area similar to an unending interconnection of rooms, which serve as abodes for hundreds of families. Within the 45-meter width, 16 54 households were identified. Three (3) households are headed by senior citizens. Average household size is 3.83. Total affected population is 211 . Majority own the dwellings that they built or acquired them buying the structure or the rights to occupy the space. The rest are either renters of the dwellings or shares. 16 The proponents initially designated 30 meters but requested that another 15 meters more be covered. Page 231 189 Residence History. Majority are old timers to the place having settled in the community between the 1920s and the 1980s . Thirty-three percent (33%) said they were born there. About 20% joined the community in the late 1990s . Community Cohesion. Majority of the respondents (63%) indicated that they are members of a community organization. Twenty-two percent (22%) said they are not organized. The rest gave no answer. Sources of Income.

A few work of employees, sales workers and maids. Household Income. Based on the NSO poverty statistics, 54% of the families live below the poverty line. But if the NAPC poverty figure us used, 80% of the household would be classified as poor. Perception about the Project Only 63% of the respondents know about the project. They got their information from the neighborhood association, from barangay officials and project personnel who did fieldwork in the area. Those who have heard about the project know that if the project pushes through that they will be displaced. When asked, in general, if they agree to the project, 67% said No. Twenty-nine percent (29%) said yes. The rest gave no answer. They were asked a second acceptability question : “ if their property will be directly affected by the project will they give up their property?” To this, 49% still said No. Most of those who previously saidyes (33% ) said “It depends”. Page 232 190 Condition to make them agree to the project are:in-city and decent relocation package, fair compensation, and financial assistance. Irasan, Kawayanan Irasan is a vernacular term for saltbed. This community is composed of clumps of not more than temporary dwellings in the fishpond/saltbed area of Pulang Lupa 1. This area is mostly private property with different owners. Some said some parts are public land. Entry into this place is via Bernabe Compound, then through a foot bridge crossing the Munting Ilog Creek. Twenty-eight (28) households were identified within the 30-meter width. Average household size is 3.4 . Total affected population is 95. Previously, it was only tenant/caretakers and fishponds/saltbed workers and their families who live here. Relatives and friends with no other place to stay later joined in. Most of the households already know about the project. When asked in general, whether they agree to the project , 89% said yes; 4% said no. The rest gave no answer. But when asked if they are willing to give way to the project if in case their dwellings will be affected, 11% said no. Seventy-one percent (71%) said it depends if their conditions are met. The conditions are: relocation (54%), fair compensation (8%) , and financial assistance (37%). 3.4.6.1 Bacoor, Cavite 17 Section of Barangay Talaba 2, Bacoor 17 See pertinent Bacoor-related tables for more details. Page 233 191 This community is located at the west side of the Talaba Diversion Road. Affected in this area are 95 households. Half of the respondent-households joined the community only in the 1990s . Half of them are long-time residents having settled in the community between the 1930s and the 1980s . The community bears the markings of urban blight but it might be too hasty to tag all the households as squatters or informal settlers. Informants revealed that the occupied land is covered by an old Spanish title which none of them had the privilege to see. Accounts say that the land belongs to certain Cuenca Sisters who were allegedly killed because of ownership conflict over said property. The title supposedly disappeared with the death of the Cuenca Sisters. Old-timers said that they used to pay lot rentals collected by self-designated relatives of the Cuencas. But through time, the collectors stopped collecting the regular rentals. As nobody knew who was in charge of the land, people freely joined the community. They secured their own spaces and built their own community. They secured their own spaces and built their own dwellings. Some unscrupulous occupants even put up additional structures for rent. Some bought rights to the space and the dwelling. Almost half are house owners and the other half are house renters. One (1) household indicated that they own their house and lot. Majority of the households (83%) are single family per dwelling occupants. Twelve percent (12%) share their dwelling with another family. Four percent (4%) live with two other families. Household size is 4.5. Total affected population is 426 . More than 40% of both male and female adult heads are high school graduates. Almost 10% are college and vocational course graduates. Page 234 192 Of the 70 male adult heads who indicated their livelihood, 62% are skilled and unskilled workers. 16% are salaried employees; 4% depend on the sea for a living; and the rest have their own small scale business. Three percent (3%) receive old-age pensions. Among the women, 74% are housewives. The rest are employees, factory workers and vendors. One has a sari-sari store. Several families gain additional income from rooms for rent, pensions, scholarships and money sent by relatives in Metro Manila or abroad. Based on NSO poverty figures, 50% fall below the poverty threshold. Using the NAPAC poverty statistics, 72% are considered poor. In terms of community cohesion, less than 20% are organized. Among the organizations mentioned are samahan ng mga Magkakapitbahay, Talaba Ladies Club, and Samahan ng mga Mangingisda. Perceptions about the Project Majority (86%) have heard about the proposed project. Information sources are: scoping meetings, barangay officials, project personnel, and neighbors. They recognize the potential benefits from the project such as: less traffic, faster means of transportation, development and improvement of Bacoor. On the other hand, they also realize that they could be displaced by the project. The area could get noisy and construction activities could get into their way. When asked if they generally agree to the project, 54% said yes and 37% said no. A few said “no choice” or “it depends”. The rest gave no answer. Page 235 193 If affected by the project, concurrence decrease 2% and non-concurrence decrease to 11% . Majority (81%) gave conditional answers. Eight percent (8%) said “no choice”. The rest said “I don’t know” or did not answer at all. Conditions to make them agree to the project are: decent relocation package (53%), fair compensation (28%), balik-probinsya package (2%) and financial assistance (2%) . Longos, Bacoor The affected section of Barangay Longos starts from the Bayer sign on the east side of the coastal road up to the bend that goes to either the Alabang-Zapote Rd. or the Talaba Diversion Road. Also affected are three dwellings behind the Samsung signage at Longos-Kanluran. The area where the census took place covers a total of 45 meters. The first census was done 30 meters from the edge of the east side of the Coastal Road where three rows of houses from the bend to the Bayer signage were covered. Later, a second census was done covering another 15 meters . The proponent still has to decide where the final 10-meter ROW will be located. Within the 45 meters , a total of 157 affected households were identified. Average household size is 5.9. Total affected population is 627 . This place is a de facto relocation site of families who were displaced by Manila- Cavite Coastal Road Project. Affected households had no place to go and they resettled here by themselves. Some asked permission from the barangay captain who had jurisdiction over the area. A few admitted that they have in fact received payments from previous relocation programs such as that in Freedom Island. It is largely public land but some respondents indicated that certain parts of it have been titled. Page 236 194 Forty-two percent (42%) are house owners on public land. Fifteen percent (15%) are house owners on private land. Thirty-four percent (34%) are house renters. Eight percent (8%) are house & lot owners, though some of them may be standing on family-owned lots. Houses are mostly one level structures made up to light materials and galvanized iron sheets or nipa shingles. There is hardly any space that separates one household from the other. In some parts along the bend are better constructed houses including the two-storey concrete house of the Longos Barangay Captain. It is in this part of the community that most of the old time residents can be found. Twenty-five percent (25%) of the male heads of the respondent-households depend on the sea for livelihood. One half are skilled workers and unskilled workers. Others operate small-scale businesses like sari-sari stores, and selling and distribution of water. A few are salaried professionals, government employees and overseas contract workers. Almost half of the women are housewives. More than 20% earn incomes from selling fish and other goods. Some are factory workers. Others have small stores or work as laundrywomen. Only a handful are professionals. More than 50% of the households fall below the poverty line, based on NSO poverty figures. Using the NAPC poverty statistics, about 60% are considered poor. Ten percent (10%) reported incomes higher than P200,000 a year. When asked if they are members of any organization in the community, only 22% said yes. Perceptions about the Project Page 237 195 Majority (92%) of the respondent-households have heard about the proposed project. They also know that part of Longos falls within the alignment which means that their dwellings could be directly affected. Most of them got their information from the barangay officials and from the scoping meetings. When asked in general if they accept the project, 69% said no and 21% said yes . Eight percent (8%) said “it depends” and the rest did not answer. If affected by the project, 91% said they can concur to the project if their conditions are met. Two percent (2%) still said yes and 6% said no . Conditions to convince them to agree to the project are: decent relocation package with facilities (43%), fair compensation (61% ), financial assistance (4%) and preferential employment and livelihood program (3%). East Side of Talaba Diversion Road, Barangay Talaba 4 This section does not fall within the ROW tract but rather an area where necessary road widening will take place. Affected here are parking areas of fifteen (15) business establishments, four (4) institutional properties, and three (3) households. These establishments range from a medium-size hospital, to a construction supply store and a kitchenette (carinderia). The institutional properties include the Bacoor Fire Station, Bacoor Police Station, Talaba Elementary School and the Talaba 4 Barangay Hall. The three (3) affected houses are a shanty, an apartment house and an elegant bungalow. Page 238 196 Most of the affected private parties are hesitant to give way to the project. For the government owned properties, the heads said that they have no choice. However if they indeed will be affected, they would like the lost space or affected building to be replaced. Extra open space at the back of the institutional properties can still be bought. 3.4.7 Measure of Social Acceptability Social Acceptability is defined in the DENR-DAO 96-37 Procedural Manual as “the result of a process that is mutually agreed upon by the DENR, the stakeholders and the proponent to ensure that the concerns of the stakeholders, including affected communities, are fully considered and/or resolved in the decision making process for granting or denying the issuance of an ECC.” It also means that the proponent is able to come up with mitigating and enhancement measures to address relevant and valid issues. These measures must be backed up by available resources to implement them, along with the proponent’s commitment, through agreements and guarantess to fulfill such measures. Based on the same DAO, social acceptability is determined by the following: (i) Ecological and environmental soundness of the proposed project (ii) Effective implementation of the public participation process (iii) Resolution of conflicts (iv) Promotion of social and intergenerational equity and poverty alleviation Item (i) is addressed by the whole EIS document, together with an Environmental Management Plan that is an integral part of the EIS. This can also be supported Page 239 197 by Barangay, municipal, or provincial resolutions endorsing the project, and endorsement letters from local NGOs and POs. Item (ii) was accomplished through the series of project presentations and consultations with the stakeholders prior to the Formal Scoping Session, together with the results of the Perception Survey conducted. An approved Scoping Report, with matrices signed by the participating stakeholders is another strong proof of meaningful public participation. As in any other developmental project that will unavoidably entail disturbance to commercial activities, conflicts with business establishments owners are expected. Item (iii) can thus be addressed through a negotiated agreement (MOA) between LRTA and the concerned business groups. Item (iv) can be addressed through an effective Social Development Program (Please refer to Section 3.4.7.6) that aims to provide venues for alternative sources of livelihood, particularly to those whose livelihood will be adversely affected by the proposed project (e.g., fisherfolks, saltbed and fishpond workers, fixed stall vendors, ambulant vendors, etc.). 3.4.7.1 Results from Scoping Meetings Based on the numerous scoping meetings held on the provincial, city/municipality, and barangay levels, and even with affected groups like business establishments and vendors, there is general public acceptance of the proposed project because of its potential contribution toward easing the enormous traffic problem within Metro Manila without adding on the air pollution load over the metropolis. Documentation of the scoping meetings corroborates this assertion. Page 240 198 3.4.7.3 Perception Survey General Concurrence to the Project Tables 3.4.4 a-c show the affected population groups, concurrence to the project. Note that the percentage of concurrence is high for both business establishments and vendors. However, fort the affected settlement areas, the percentages of acceptability vary.

Conditional Acceptability (from affected households) Careful analysis of the alignment acceptability data shows that the project can be made acceptable to directly affected communities for as long as their conditions of proper relocation and reasonable negotiations are met. Note also that letters from organizations representing affected communities do not categorically endorse or reject the project. They request for clarity on what packages will be offered to affected households depending on their status of occupancy or ownership.

It is however, very encouraging to note that alignment acceptability in the Coastal Road section is rather high at 95%. Furthermore, Mr. Cailles, Barangay Captain of Baclaran, also stated in an interview that things can be settled through a series of negotiations with the concerned business establishments.

Ambulant vendors 5.88 2.94 85.29 2.94 2.94 Acceptability (Vendors) 5.22 3.75 84.69 3.75 2.61 Analysis of Votes Looking at the second column of Tables 3.4.5 a-c which give the number of “Yes” responses to a question if they are willing to give way to the project if they are directly affected, one would readily conclude that project acceptability is very low. That is, only 2.28% from the affected households, 40.38% from business establishments, and 5.22% from vendors said yes. Comparing these values with the general concurrence to the project (Tables 3.4.4a-c), one can clearly see that these businessmen are NOT against the project, in fact they are FOR the project, as long as it does NOT directly affect them. This trend of thought is strongly manifested by high YES answers in Table 3.5.4b and c and very low YES answers in Tables 3.5.5b and c . This is understandable since most businessmen would welcome a mass transport system that can deliver so many customers at one single time. However, not all of them would be willing to sacrifice some losses in income during the construction period. Page 245 203 The vendors are in a more difficult situation since they don’t have that much savings to cover losses but on the contrary, even have loans to pay. Based on the socioeconomic survey conducted, almost 70% say that their capital are sourced from either private individuals or lending institutions, a high percentage said they had to turn to usurious loans or “5-6” for their revolving capital. These loans, aside from having interest rates, are paid on a daily collection basis. Surprisingly for the affected households, a high 74.87% gave CONDITIONAL answers against only 17.62% NO vote. Analyzing the conditions they cited during the survey, the top two answers are (i) “decent in-city relocation package” and (ii) “just compensation” . This means that if the Proponent can make the necessary arrangements to address these conditions, then these conditional votes may become YES votes. 3.4.7.3 Process Documentation The Need for Process Documentation The Proposed alignment will traverse three (3) cities (i.e Pasay, Las Piñas, and Parañaque), and the Municipality of Bacoor in Cavite. These areas are currently densely populated, albeit most of the segments of the alignment are found within public domain. The Department of Environment and Natural Resources’ DAO 37 Series of 1996 categorically states the need for social acceptability in projects that affect the lives of the stakeholders. In the event that some stakeholders are found to have justifiable issues and concerns regarding the project, the Project Proponent must go through all means possible – initiate dialogues/consultations to reach certain reasonable agreements. Conduct information and educational drives, etc. – to Page 246 204 convince the stakeholders that the project will not create major impacts on their lives. The LRT Line 1 South Extension Project initially encountered negative perceptions from the stakeholders. It is therefore imperative to discuss the process by which the Proponent, through its Community Relations Team (COMREL), launched two (2) programs – Information Education and Communications (IEC), and Community Relations (ComRel) Campaigns. Five (5) months after the EIC and ComRel activities have been conducted, most of the stakeholders have recognized that the Project will not totally disrupt their economic and everyday activities. Major Issues and Concerns In this project, the construction of the Baclaran segment will temporarily affect the economic activities of building owners and. Brgy. La Huerta A series of meetings with certain individuals ensured. Major Joey Marquez requested that the alignment be moved to other parts of the City because of the representation of the residents from the area. Further, Congressman Roilo Golez organized a consultative meeting where the Proponent and the residents were given the chance to present their respective sides. Due to the concern and clamor verbalized by the residents and local officials, the Proponent is considering the use of Brgy. Sto. Niño, at the northern side of Parañaque River, as an alternative route. Page 247 205 Squatter Families Along the Danger Zones A pro-active relationship has been developed between the stakeholders and the Proponent, through its ComRel Team. A highly participatory approach is currently bring implemented in the selection of possible relocation sites. Health Morbidity and Mortality Available data on mortality rates were obtained from the municipal records of Parañaque and Bacoor, and are attached as Appendix G . Note that for Bacoor, data re limited to Barangays Talaba II, III, V and VI only. Health Facilities A list of hospitals, private clinics, private physicians, private dentist, lying-ins, drug stores, and dental clinics were obtained from the Office of the Municipal Health Officer of Parañaque and is provided as Appendix H.

However as ore areas are developed in the highlands and coastal areas, less and less sediment supply will be available for deposition. Surface Hydrology Without the project the coastal plain will continue to function as natural catch basin surface water coming from the flanks of Guadalupe Plateau and Tagaytay Hihglands. Page 250 208 The catchment basin at the coastal plains on the other hand had bee converted into fishponds and salt beds. Large areas where filled up and reclaimed, and the banks of channel system encroached with various froms of structures. The construction of water channels is aggravated by rapid siltation through uncontrolled dumping of garbage. Though various alterations have been made, the function of the area is still and will remain a catchment basin for a runoffs coming from the highlands thus making it prone to floodings. Land Use The main land use types will generally remain the same. However, the area had been experiencing rapid urbanization which triggered the conversion of some land into other use. Notable of this is the conversion of some land into other use. Notable of this is the conversion of some agricultural land into Commercial and residential use. It may be worth nothing that due to the area’s susceptibility to liquefaction and subsidence, future expansion should be located in zones underlain by bedrock and more competent materials. Air Quality and Noise Level The existing ambient air quality and noise levels in the area will remain relatively the same wihtout the proposed project. However, gradual increase in TSP concentrations and levels of noise may be expected due to natural increase in population and the addition of vehicles plying the existing roads. Without the proposed project, the chance to reduce emission rates and concentrations of air pollutants (9TSP, SOX, CO, HC, NOX) by means of a shift from vehicles emitting these pollutants to an electrically powered rail system, and would be missed. Page 251 209 Through the provision of an effective inter-modal system, traffic flow can be much improved, and thus reduce traffic congestion. This, in turn, will reduce the vehicles idle operation time, which causes incomplete combustion of fuel, thus minimizing pollution. Without the proposed project, these cannot be realized. Given the worsening traffic condition in the project corridor, levels of air pollutants may even drastically increase. Climate Without the project, there are no major development in terms of infrastructure and industries in the area that are foreseeable in the future. Thus, changes in the local climate due to urbanization are not ex;pected to happen. 4.2 Biological Environment Flora Without the project, the flora community withint the project area will remain the same. The patches mangrove species observed somehow is expected to be turned into a mangrove forest. In the real sense. However, this can only happen if the water quality of river systems within these mangrove areas will not continue to decline. Another requirement for a healthy mangrove area is the supply of sediments needed by the tree species as a substrate that serve as habitat for other marine organisms such as oyters, crabs, and other bivalves. Given the continuous and extensive land development (filling up of highland areas and backswamps), there may come a time that these mangrove areas eventually perish due to lack of sediments, or improper proportions of salt, water, and organic content Page 252 210 Fauna Without proposed project the type and distribution of terrestrial fauna (mainly domesticated animals) is expected to remain the same. The limited number and type of aquatic fauna I expectd to remain the same, given the very high BOD levels. However, if the dumpinf of pollutive effluents into the river sytems in the area continues, there may even come a point in time when even the simplest from of aquatic life cannot be sustained by these river systems. 4.3 Socio Economic Without the proposed project the following envisioned benefits CANNOT be realized: · Enhancement of workforce mobility between the industrial zones in Valenzuela, Bulacan, and the CALABARZON area; · Enhancement of stud ents’ mobility and productivity in coming to and from Metro Manila and the Southern Tagalog region; · Enhancement of the Acceptability of Off-Metro Manila Relocation Sites; · Additional entry points into Las Piñas and Parañaque, instead of queuing through Quirino Ave.; · Decongestion of the entry point into Cavite and the CALABARZON; · Boosting of developing business/commercial/tourism areas in Las Piñas, Parañaque, and Bacoor · Increased income fo host LGUs as a result of development; · And other indirect benefits as a result of better and more efficient mobility and access.

Based on the evaluation of the identified impacts, appropriate mitigating measures are recommended. Pre-construction Phase Physical Environment In assessing the probable impacts of the existing physical environment to the proposed LRT Line 1 Extension Project, The EIA Team adopted the concept of a preemptive mitigation. Preemptive mitigation is the process of anticipating and investigating the dynamics and processes that would trigger the occurrence of a hazard before it occurs. Geology Page 255 213 IMPACT: The proposed Extension Route lies in the vicinity of a seismically active area that could induce grounds shaking. (Long-term, negative) Ground shaking is one of the destructive effect of an earthquake, which commonly results to damage or destruction of structures. Experience suggests the need to know more about the surficial and subsurface geology at sites likely to be affected by earthquakes and about the response of geologic formulations and large structures to strong ground motion. MITIGATION: The seismic risk at particular sites have to be characterized before building critical public structures that can reasonably be expected to resist earthquake damage. This could be met by developing methods to accurately account for. · the fault-rature process of a predicted earquake; · the geology along the seismic wave’s path of travel (the propagation path) from fault to a particular site; · the subsurface geology at sites expected to be affected by this predicted earthquake; · the non-linear response of geologic formulation to strong ground motion; and · the non-linear response of large structures to strong ground motion. Civil structures are designed to remain elastic and exhibit little or no damage as a result of small earthquake. For large, less frequent earthquakes, however, it is Page 256 214 economically unrealistic to design structures that can remain entirely elastic. By design, structures are expected to suffer damage when subjected to large earthquakes. A key requirement for modeling the mechanical response of a structure is knowledge of realistic estimates of how the ground beneath the structure will move during an earthquake. Methods for predicting ground motion at specific sites that would result from earthquakes on known faults. Accurate numeral simulations of the nonlinear behavior of soil and structures can provide a more realistic picture of how a structure actually responds during strong ground motion. With this information, engineers can be more confident that a designed structure will survive a large-magnitude earthquake. These analyses can provide valuable information on designing structures for seismic safety. Realistic nonlinear analysis provides a tool for making the seismic calculation and assist in the development of more economical design schemes. IMPACT: Ground rupture commonly occurs along fault traces and rupture zone consequential to the movement of active faults. (Long-trem negative) Ground rupture commonly occurs along fault traces.Some quarters believes that ruptures zone consequential to the movement of Marikina Fault may be present. Evidences of this fault tracers remains obscured by the urbanization in the metropolis. MITIGATION: With the Marikina Fault’s proximity to the project area and in light with the Kobe earthquake experience it may be prudent to validate such possibility so appropriate measures could be applied if so warranted. IMPACT: Susceptibility to liquefaction and ground settlement. (long-term, negative) Page 257 215 Since the proposed alignment lies is an area underlain by unconsolidated send, silt, and clay materials that naturally posses high liquefaction potential, the structures and stations may be highly susceptible to these geomorphological hazards. Results of the intial five (5) boreholes drilled along the alignment, plus data from adjacent subsurface investigations for other projects show that the subsurface soils mostly consist of generally sot/loose marine deposits near the ground surface, overlying the residual soils of Guadalupe tuff material (SNC Lavalin 1999) MITIGATION: The following mitigation measure was taken from the Technical Plan of the Offer for implementation and Operation prepared by LRTA. “The geological conditions and local geotechnical experience suggest the use of bored cast-in-place reinforced concrete piles with diameters of 1000-1800 m . These piles are to be designated based on skin friction and will extend from 8-22 meters in depth depending on site conditions. For the loads and forces imposed on the guideway substructures, the foundations will consist of groups of piles with a pile cap. Pile groups will vary from six to twelve piles with an average of nine piles for the guideway columns. The pile cap size will vary with pile group size with an average size of 8.5 m 2 by 1.3 m deep. Alternate foundation using a single diameter caisson per column has also been explored and could show some advantages in schedule and cost. Equipment availability is an issue with this type of construction and will need further investigation during the design development. The installation of bored caissons within marine or river environments is difficult and costly. Driven steel or pre-cast concrete piles are typically more appropriate Page 258 216 in these condition but do not appear to be used to any great extent in the Manila construction market. An investigation to the availability of equipment and reliability of such installations in the local area will be evaluated during the design development phase. The geotechnical investigation has found liquefaction indicators in boreholes 1, 2, and 3 at Redemptorist, MIA, and Dr. Santos Stations respectively. (Please see Figure 2,34 for the borehole locations). In boreholes 1 and 3 the areas of liquefaction risk are near surface in relatively thin. At borehole 2 , the liquefiable layer is about 9 meters below grade. Based on the conditions found at boreholes 1 and 2, no ground conditioning has been provided for this area. In the case of borehole 3, an allowance for downdrag on the piled foundations in this area has been provided for. In general, since the geotechnical investigation has found very little evidence of potential for surface or near surface liquefaction flow, there has been no provision for ground conditioning for any of the foundation,” Considering that a limited number of boreholes were used to have an ideas of the condition of the foundation material, a more detailed subsurface investigation is deemed necessary. This can be undertaken in consonance with the detailed. Engineering Design Stage so that the potential for liquefaction and ground settlement for certain sections can be more ascertained. Air and Noise Quality IMPACT: Increase in exhaust gas emission levels with the operation of different pre- construction equipment. (Short-term, negative) Page 259 217 Exhaust gas emission such as NO2, SO2, CO, hydrocarbons, etc.generated by the different pre-construction equipment and machinery that would be utilized for site clearing and grubbing. MITIGATION: One of the factors affecting the ambient air quality is the increase in exhaust gas emission such as NO2, CO, hydrocarbons, etc. produced by the different pre- construction equipment and machinery. To control such emissions, and to prevent drastic effects especially to personnel handling the job, regular maintenance of the construction heavy equipment and other smoke emitting machinery must be strictly complied with. The measures will help minimize emission of noxious gases and even particulates. IMPACT: Increase in noise level due to operation of various pre-construction equipment and machinery. (Short-term, negative) Noise level is expected to increase during due to the roar and racket from various pre-construction equipment and machinery. MITIGATION: It is expected that noise will be generated during the pre-construction phase of the project particularly during demolition/clearing of permanent structures along the alignment. This impact can be addressed through proper scheduling of high noise generating pre-construction activities during the daytime. Temporary noise barriers such galvanized iron shields must also be used particularly in noise- sensitive areas such as churches, schools, and hospitals in the immediate vicinity of the construction area. Page 260 218 Being the direct noise receivers, construction workers must be provided with earmuffs. The use of mufflers and noise suppressors, and regular maintenance of heavy equipment, construction machinery, and other support vehicles is also recommended. Biological Environment Flora IMPACT: Minimal loss of the natural and cultivated vegetative covers in areas traversed by the alignment. (Insignificant) Site clearing and grubbing activities along the areas traversed by the alignment will unavoidably cause the removal of natural (i.e. mangroves and other coastal vegetation) and cultivated vegetation covers (along center medians) MITIGATION: The mangrove species observed along the route is very limited and only occurs in patches. The guideway alignment will cause minimal effects on the mangrove species and other coastal vegetation covers since it will be fully elevated and will be on columns. It is expected that disturbance of mangroves will occur during pre-construction and construction stages. Proper relocation of the mangrove nursery at the back of La Huerta Elementary School, where the proposed Ninoy Aquino Station is located, will be accordingly coordinated to the proper authority/agency such as DENR-Region IV and U.P. Los Baños. Page 261 219 To compensate for the trees that would be cut during project implementation, the Proponents must comply with the governing rules and regulations regarding tree cutting. Aquatic and Terrestrial Fauna IMPACT: Pre-construction and construction activities along the rivers and creeks traversed by the alignment will pose no significant effect on aquatic fauna. This is because the present physico-chemical condition of the waterways , particularly the high level of Biological Oxygen demand (BOD), cannot support survival of higher form aquatic faunas. Some Biological indicators obtained from the water collectors from Parañaque, San Dionisio, and Las Piñas Rivers such as species of phytoplankton, the Ceratium sp. Support this observation. The deformation of the organism’s morphological structure is an indication that something is wrong in the habitat system. Like lack of nutrient and heavy metal lods. Zooplankton such as the Cladocerants, Coppepods, and Rotifers were also observed. Presence or absence of certain organisms is also an indication of water pollution. Good examples are absence of gastropods and dominance of mosquito fish. Guppies or commonly known as mosquito fish are highly tolerant of pollutants while other organisms are threatened. Since the project area will traverse urbanized areas, it is not expected to have any significant effect on existing terrestrial fauna, since most of these are of the domesticated type. (i.e. cats, dogs, chickens). Socio Economic Environment Page 262 220 IMPACT: Permanent displacement of residential houses, and few commercial and business establishment along the right-of-way-of the alignment. (Long- term, negative) Like all other infrastructure projects with earthmoving activities, especially those passing thorough congested residential areas like Metro Manila, the proposed project will potentially displace residential communities in various locations as indicated in Table 5.1. Displacement of informal settlers on public land, NHA awardees/applicants , privately owned houses and lots major concerns.

Talaba 4, Bacoor Cavite 3 1 2 TOTAL 378 529 15 Note: The number of affected households in settlement areas will decrease, because during actual construction the impact area could be 10 instead of 30 m. MITIGATION: Different packages will have to be designed according to the types and specific situations of population groups that may be displaced by the project. Project proponents have to realize that affected groups will not voluntarily put up their homes and properties for sale. They are being asked by the Proponent and the government to give way to the project. As such, the guiding attitude should not only be towards offering acceptable packages but to open up opportunities for them to improve the affected communities’ current situation. Only through the latter can the pain of displacement and fear for uncertainties can be addressed. Private property owners comprise the less difficult groups to transact with. Schedule of fair market values from various institutions (e.g. Development Bank of the Philippines, real estate agencies, etc.) can be use to draw up acceptable pricing standards. Thereafter, case-to-case negotiations can proceed. All means have to be exhausted to maintain the gains of NHA lot awardees/applicants. if they need to be relocated they should be extended the same if not a better package than what NHA has already given them. NHA advice has to be sought to ensure that the lot awardees and applicants do not forfeit the opportunity that NHA has offered them. Page 264 222 Informal settlers do not comprise a homogenous group. Different packages will have to be worked out for the following: · Those qualified for relocation/resettlement (They should satisfy the NHA requirements such as: long-term residency within the community; with their own dwelling structures; falling within the poverty line; not owning any property elsewhere.); · Shares; · Renters; · Other types of community dwellers; · Sea-dependent dwellers · Women-headed households; and · Senior citizen-headed households A community Relations Group (CRG) is currently on field to attend to social preparation requirements and to facilitate communication and negotiations with affected households and private property owners. The CRG is also closely coordinating with the host LGUs and appropriate agencies of government towards the formulation and implementation of a multipartite Social development for Affected Communities (Please refer to Section 6.3 of this report) Construction Phase Physical Environment Hydrology and Water Quality IMPACT: Page 265 223 Possible increase in turbidity and downstream sediment loading of the rivers, creeks, and tidal channels along the propolsed alignment due to excavation and bored piling activities. (Short-term, negative) MITIGATION: Excavation and pile driving activities have its own potential impact on adjacent water qualify. During excavation, displaced, newly exposed, loose, unconsolidated materials will be subject to immediate erosion losses during high precipitation periods. Soil/sediments transported may be carried directly to an. IMPACT: Possible aggravation of existing flooding problems in San Dionisio, La Huerta, Manuyo 1, Pulang Lupa, Longos, and Talaba. (Short-term negative) The following activities may aggravate the existing flooding problems in the above mentioned areas. · Improper handling, storage, and hauling of excavated materials, particularly along station location may clog existing drainage systems. · Increase in stormwater run-off due to the increase in the amount of imperrmeable surfaces (as a result of the viaduct, road and station construction) would change the flood storage capacity of waterways and its floodplains. · Filling up or raising of previously swampy areas (such as NInoy Aquino, Dr. Santos, Manuyo Uno, Las Piñas and Zapote stations) above the present elevation would result in to a change in run-off pattern, aggravating flooding in the lower-lying areas. MITIGATION: It is important to note here that flooding is an existing environmental problem in the project area, and that it is not the goal of the proposed project to solve this. Page 266 224 Aside from being natural receptacles of water (being geomorphologically a catch basin), flooding problem in the above mentioned areas have been aggravated by rampant filling of large tracts of wetlands without providing proper drainage facilities. Worst than this is that even natural waterways have been filled up. In addition, fill materials used in some areas are impermeable trashes that contain large quantities of plastic. Given this situation the proponent must ensure that appropriate mitigating measures are put in place and strictly complied with, so that these areas can be protected from further degradation. These are: · Contractor must be prohibited from stockpiling construction spoils anywhere near watercourses nor artificial drainage systems to avoid clogging of these drainage systems. · Conventional sedimentation and erosion control measures must be put in place; · Sufficient and effective drainage systems must be incorporated in the detailed design of the structures and stations to offset effectes of increase in amount of impermeable surfaces as well as differences in elevation between the raised (construction) areas and the surrounding low-lying communities. Air and Noise Quality IMPACT: Increase in Toatal suspended Particulate (TSP Levels to dust generated during construction. (Short-term, negative) Dozing, ripping, loading pile hammering, and rock and/or earth moving activities within the project site during construction period will contribute to the generation of dust aside from the regular traffic movement along the existing roads. Page 267 225 MIGITATION: The impact regarding the increase in the TSP levels during the pre-construction and construction stage of the project can be mitigated through spraying of the exposed and/or cleared sites with the use of water spraying tankers. IMPACT: Increase in exhaust gas emission levels with the operation construction equipment (Short-term, negative) Exhaust gas emission such as NO2 ,SO2, CO, hydrocarbons, etc. are also predicted to be present once construction activities commence with the operation of the different construction equipment and machinery. MITIGATION: One of the factors affecting the ambient air quality in the construction area is the increase in exhaust gas such as NO2, SO2, CO, hydrocarbons etc. Produced by the different construction equipment and machinery. To control such emission, and to prevent drastic effects especially to personnel handling the job , regular maintenance of the construction heavy equipment and other smoke emitting machinery must be strictly complied with. This measures will help minimize emission of noxious gases and even particulate IMPACT: Increase in noise level due to construction activities. (Short-term, negative) Noise level is expected to increase and cause disturbance particularly during construction, due to the roar and racket from the heavy eqauipment. MITIGATION: Page 268 226 Noise generation, though inevitable, can be effectively reduced and minimize to comply within tolerable levels, through: · Provision of temporary noise barriers such as galvanized shields, enclosing the construction area, particularly near Baclaran Church, Iglesia Ni Kristo Church, San Nicolas Church, La Huerta Elementary School, St. Paul’s College, Las Piñas Elementary School, Talaba Elementary School, St. Dominic Hospital, and other highly populated areas; · Provision of earmuffs to the construction personnel operating the heavy equipment · Use of mufflers and noise suppressors for the construction heavy equipment and machinery when noise levels are expected to go beyond tolerable limit; · Proper scheduling of construction works; i.e. high noise generating activities must be scheduled during the daytime; and · Regular maintenance of heavy equipment, construction machinery, and other support vehicles through checking of observed abnormal noise and vibration. Bored piling, a lower noise generating activity compared to pile driving will be adopted during foundation works. Socio Economic Environment IMPACT: Generation of employment within the project area. (Short-term, positive) Page 269 227 During the construction period, temporary employment will be available, particularly to residents within the direct impact area. ENHANCEMENT: Priority in hiring of qualified laborers and workers during the construction period must be given to the residents in the direct impact area IMPACT: Disturbance of business activities in affected commercial areas: (Short-term, negative) Owners of commercial buildings and establishments and ambulant vendors along the Redemptorist Road will experience temporary disturbance to their business activities during the construction period. Yet the building and establishment owners claim that they could possibly experience a fatal decline in business similar to what happened in Avenida Rizal when the LRT Line 1 was built. This contention cannot be easily negated because of the absence of empirical cause-effect post-project evaluation studies on LRT Line 1 The redeeming factor for the Redemptorist Road commercial area is that unlike in Avenida, refurbishing and modernization of buildings have consistently been undertaken to boost its attractiveness customers and consumers. Presently, it has the elements of an upgraded commercial center (big airconditioned malls, department stores, new theaters, major food chain establishments, moderately priced wholesale and retail merchandise) to ensure massive and consistent patronage. This is not to mention the 10,000. devotees that go to Baclaran Church every Wednesday for the perpetual Help Novenas. Fixed stall owners and vendors on the south sidewalks of Redemptorist Road will have to be temporary displaced to give way to the LRT structure. Page 270 228 If indeed business activities would be hampered, Barangay Baclaran would also be negatively affected in terms of decreased daily dues from vendors and decreased income taxes from the establishments. MITIGATION: Further consultations have to be pusued with affected business establishments and vendors along Redemptorist Road to convince these affected groups that the proposed project is far improved version of the first LRT project. The proposed project takes into full consideration stakeholders concerns related to economics, aesthetic, space, traffic and culture. Construction activities in the Redemptorist Road section will have to be undertaken in the shortest period of time, in consideration of the affected groups including the Mother of Perpetual Help Shrine and its devotees. Vendors will have to be temporarily relocated to the other parts of the Baclaran commercial area so as to minimize economic dislocation. Proponent has to work this out with the municipal and barangay LGUs concerned. In the extreme the proponent may have to prepare for safety net programs for vendors, establishments and small-medium enterprises (SMEs) in cases of extended construction time, which may lead to major financial difficulties for these groups. Financial consultants may have to be tapped for this purpose. The informal Sector of the national Anti-proverty Commission may also be in position to render some advice with regard amelioration and alternative livelihood programs for affected vendors. The above discussion focuses on the adverse impacts of the project during the construction period. It should be noted that these are short term impacts only. A completely different scenario can be expected during the operational stage. In a meeting held in August 6, 1999, representatives from Metropolitan Manila Page 271 229 Development Authority (MMDA) informed the proponent that they will declare the Redemptolrist Road as pedestrian mall with only one service lane for vehicles going to the Baclaran Church. A draft Memorandum of Agreement (MOA) between the proponent, the MMDA, the Parañaque Local Government Officials, and the affected stakeholders is currently being reviewed. These condition meetings with various national agencies such as the MMDA shall continue until a sustainable and workable Stakeholders-Proponent relationship is attained. IMPACT: Disturbance of institutional buildings and places of worship. (Short-term, negative) Parts of the alignment will be located uncomfortably near schools and two churches. Concern have been raised about noise disturbance in several schools namely: Las Piñas elementary School, Talaba Elementary School, St. Paul College in Parañaque and High School in La Huerta. The problem for Talaba Elementary School is bigger in the sense that road widening will eat up part of the school grounds and possibly part of one of the school buildings. Road widening will bring the school dangerously near to The Talaba Diversion Road. Road widening will also affect other institutional properties along Talaba Diversion Road such as the Bacoor Fire Station, Bacoor Police Station and the Talaba 4 Barangay Hall. Page 272 230 if the station along the Real St. near Las Piñas elementary School materializes, the school may experience severe noise disturbance not only from the LRT system but from increased passenger/vehicle volume coming to and leaving the station. MITIGATION: Noise barriers aesthetic features shall be incorporated in the LRT structural design in keeping with the over-all atmosphere of the Baclaran Church, while also complementing the modernization effort in the Baclaran Commercial Area. This is also in consideration of the requirements of school zones IMPACT: Right-Of-Way Acquisition for the proposed LRT Line 1 Extension will cause minimal property losses. (Long-term, negative) Since proposed alignment will only require a maximum of 10 meters ROW, losses to properties are expected to be at the minimum. MITIGATION: Just compensation based on the existing DPWH Right-Of-Way Acquisition Guidelines must be accorded to property owners. IMPACT: Increased traffic congestion and changes in traffic patterns. (Short-term, negative) It will be necessary to restrict some roadway, parking and footpath space for use by construction activities and staging of the works (i.e., construction vehicle access; storage of materials and equipment). The types of temporary impacts Page 273 231 which will be experienced by the traveling public will include increase traffic congestion and changes in traffic patterns. These will be as a result of either voluntary alterations in trip routes by motorist, cyclists and pedestrians attempting to avoid construction zones, of instituted strategic re-routing (detours) of all traffic (based on MMDA-approved Traffic Management Plan. This may result in avoidable delays to trip makers. It is expected that during the course of the construction period the level of initial inconvenience will be reduced as trip- makers who are able to so adjust the timing and or/patterns of travel. MITIGATION: The MMDA-approved Traffic Management Plan must be strictly implemented. To further improve traffic flow, blockage of roads, particularly by heavy equipment and vehicles (such as delivery and hauling trucks) must be minimized if not avoided. Transport of guideway beams must be done during the nighttime when there are less vehicles on the road. IMPACT: Possible disturbance to underground and overhead utility lines (water, sewerage, gas, electricity, Telephone) during excavation and erection of fixed facilities. (Short-term, negative) Aside from these, some individual service lines may require relocation. A detailed assessment of construction requirements will be conducted during the development phase. In addition to work in the immediate project area, the introduction of the power supply connections between local grid stations and the LRT traction power sub- station will require excavation for underground installation of cable. The lengths of these power supply connections will vary from station to station. These excavation activities also have the potential for disturbance of existing underground utilities. Page 274 232 Furthermore, local emergency services (fire, police, ambulance) may require some rerouting as a result of the aforementioned barrier effects during construction of the viaduct within major roads corridors. The effects of such disturbance are expected to be short term and are typically related to cutting in of services which have been relocated. MITIGATION: Works involving service interruptions will be dealt with in an expeditious, internationally accepted-manner which reduces disruptions to a tolerable level. For example, if a major relocation is required, theline will be laced in its new position without activating it and will be subsequently cut in quickly during low consumption periods to minimize inconvenience all authorities. All of the major authorities. Having jurisdiction over the provision of utilities will be contacted, as necessary, during the development and implementation phases. Reducing disruption of municipal services (police, fire, ambulance) will be addressed through the staged construction and traffic maintenance strategies to be developed as part of the Traffic Management Plan. 5.1.3. Operational Phase Physical Environment Air Quality IMPACT: Decline in emission rates and concentrations of air pollutants (Long-term, negative) Page 275 233 Result of ambient air quality sampling very high concentrations of TSP, Sox1 and NOx1 which may be attributable to vehicular exhaust emissions. In general it is expected that there will be a considerable long term impro0vement in air quality along the project corridor as a result of the operation of the LRT Line 1 Extension. One way is through the reduction and better management of bus and jeepney routes/traffic serving the serve corridor, reducing the emission of harmful diesel exhaust from vehicles that old and poorly maintained. The decline in emission concentrations can thus be attributed to the replacement of vehicles emitting carbon monoxide (CO), total hydrocarbons (HC), and nitrogen oxide (NOx) by an electrically powered LRT System. Consequently, there will be a remarkable reduction in traffic congestion, increase in average vehicle speeds, and decline in the vehicles idle operation time, thus decreasing CO and HC emissions. With regards to secondary vehicle pollutans such as total suspended particulates (TSP), particulate matter 10 microns (PM10), lead and sulfur dioxide (SO2) studies of seminar transit systems indicate that the overall impact of an introduction an LRT System would be a decline in emission rates and concentration. Noise Quality IMPACT: Possible increase in the level of noise due to train operation . (Long-term, negative) Prediction of the resu ltant noise level based on Peter’s model (See Chapter 1 for Methodology) was conducted to qualify possible impacts of LRT Operation to “noise-sensitive” areas such as the Baclaran Church Results of the computation are presented in Table 5.2 Page 276 234 Table 5.2 Predicted Resultant Noise levels For 34-kph train speed For 60-kph train speed Distance* From LRT-1 Extension (Computed) From Baseline Data (Actual) Resultant (computed) From LRT-1 Extension (Computed) From Baseline Data (Actual) Resultant (computed) 10 m 71.6 62.0 72.1 77.8 62.0 78.0 30 m 65.6 62.0 67.2 71.8 62.0 72.2 60 m 60.6 70.0 70.6 66.8 70.0 71.7 Note: Distance from train bridge centerline (source) to the observer (receptor) 10 m – observer’s location is approximately along the Redemptorist Road 30 m – observer’s location is approximately midway between the source and the church Door 60 m – observer’s location is approximately beside the Baclaran Church side door The following findings are drawn from Table 5.2 (i) Existing noise level inside the Baclaran Church premises (i.e. near the Side door), based on actual measurements (21 July 1999 sampling) are Actually higher than the noise to be generated by the operation of the LRT train (See Chapter 3 for computation) (ii) The predicted resultant noise levels (Actual + LRT Train) namely, 0.6 dB(A) (for 34 kph train speed) and 71.7 dB(A) (for 60 kph train speed) do not significantly differ from the baseline data of 70 dB(A), having differences of only 0.6 and 1.7 dB(A) respectively Page 277 235 (iii) Noise levels along the Redemptorist Road would significant increase from 62.0 dB(A) to 72.1 and 78.0 dB(A) for train speeds of 34-kph and 60-kph, respectively. (iv) In the same manner, noise levels at 30 meters away from the source would also significantly increase from 62.0 dB(A) to 67.2 and 72.2 dB(A) for train speeds of 34-kph and 60-kph, respectively. It can be reduced from these findingd that the operation of the LRT trains, whether at the minimum 34-kph or maximum 60-kph, will NOT significantly affect the Baclaran Church activities in terms of nuisance from the noise it will generate. MITIGATION: Although effects on the Baclaran Church religiously rites/activities are expected to be minimal, it may be worthwhile to adopt noise minimization measures such as the provision of noise barriers, or by using shock absorber pads and ballast to help reduce noise and vibration. Socio Economic Impacts IMPACT: Enhancement of workforce Mobility & Productivity. (Long-term, positive) The LRT Line 1 which starts in Monumento and the LRT Line 1 Extension which initially ends in Bacoor but which could be extended to Imus and Dasmariñas comprise an integrated system. One major positive socioeconomic impact of this project is providing an effecient mass transit system that enhances workforce mobility between the industrial zones in Valenzuela, Bulacan and the CALABARZON area. This fast and continuous means of transportation gives the labor force in NCR and parts of Region IV more chances of getting available jobs without having to consider the distance between their home and their place of Page 278 236 work, Ultimately, residents of Metro Manila and its spill-over population would be served. Shorter travel time and more comfortable travel circumstances also allow workers a better physical and psychological state to undertake productive work. Consequently, Project benefits can be translated into higher labor productivity. IMPACT: Enhancement of of Students’ Mobility and Productivity (Long-term, positive) Metro Manila, particularly Manila and Quezon City is a major educational center. Cavite is also developing into an expansion site for tertiary educational and technical training. Just as comfort and speed have been extended to workers, the same is also being preoffered to students. Through this improved transport system within Metro Manila, improved students’ performance can be expected. IMPACT: Enhancement of the Acceptability of Off-Metro Manila relocation Sites. (Long-term, positive) Congestion in Metro Manila is a given. As such, most resettlement efforts have been directed away from the metropolis. Further, relocation sites outside of NCR have always met strong opposition as relocated families become economically dislocated because of lack of livelihood opportunities in the resettlement areas. They also complain of being cut off from their former places of work or sources of income and sustenance. One strong impact that this efficient mass transport system could being is its capacity to bridge the distance between off-metropolis relocation areas and livelihood centers such as markets in Baclaran, Divisoria, Pasay and Quiapo and factories within and immediately outside of Metro Manila. Page 279 237 With the proposed integrated and continuous LRT system from Monumento to Bacoor, social acceptability of relocation sites is hoped to be enhanced. IMPACT: Additional Entry Points into Las Piñas and Parañaque. (long-term, positive) Presently, entry point into Las Piñas and Parañaque are limited and congested. Entry into Las Piñas from northern Metro Manila is via Quirino Avenue and the more circuitous route via the coastal Road and Alabang-Zapote Road. Routes to Parañaque are through the south Superhighway and also via Quirino Avenue. The proposed project adds entry points into Parañaque and Las Piñas. It enhances the efforts of the Las Piñas City government to realize its goal of making Las Piñas the Gateway to CALABARZON. IMPACT: Decongestion of Entry Point into Cavite and CALABARZON. (long-term, positive) Currently, Bacoor, being one entry point into the CALABARZON from Metro Manila, faces enormous traffic problems because of its narrow road system. This can not be easily remedied by road widening initiatives due mainly to budgetary constrains but also of complicated and explosive Right-of-Way acquisition procedures. The project creates the benefit by way of accommodating expanding ridership between various parts of Metro Manila and Cavite. If more passenger are encourage to take the LRT, other public utility vehicles like jeeps, mega-taxi and buses plying the narrow Bacoor Streets can be reduced. So as not to completely displace these public utility systems, terminals can be set up along Aguinaldo Avenue to encourage them to go into southward routes leading to the various industrial-economic zones and even domestic tourism destinations within and outside cavite. Page 280 238 IMPACT: Boosting of Developing Business/Commercial/ Tourism Areas in Las Piñas, Parañaque & Bacoor (Long-term, positive) Heavily considered in the project alignment are currently developing and future commercial s ites in Parañaque and Las Piñas. Three of them are the Boulevard 2000, the Las Piñas commercial center in Manuyo I and the SM Complex along Dr. A Santos Avenue. The Uniwide Coastal Mall and its occupant enterprises forsee a strong boost in terms of patronage as a result of LRT line 1 Extension riders that will alight from and embark in the planned station in front of the Coastal Mall. LRT stations are similarly planned for Ninoy Aquino Avenue and the planned commercial centers in Manuyo 1. IMPACT: Pro-rated Tax Payments to or Profit sharing Schemes will benefit Host LGUs (Long-term, positive) So that local Government Units especially those on the barangay level can learn to appreciate the project’s potential benefits, the LRTA may have to consider how its operating organizations can make pro-rated tax contributions to host organizations of the LRT system. Presently no endorsements have come from barangay LGU as the official cannot see direct benefits accruing to their barangays. If the LRT charter does not allow tax payments, other possible benefit packages for LGus can be worked out. These could be in the form of civic project (sports, education or social service). Page 281 239 OTHER ENHANCEMENT MEASURES: · it is unclear to the LGUs (based on the LRT Line 1 Experience) how the management and maintenance of the LRT structure including the spaces below, and the LRT stations will be undertaken. Early on, LRTA must come to a decision on this and which must be consequently communicated to concerned LGUs. Budgetary requirements must also be discussed. · It is also came out during the scooping session that the LRT Line 1 project must be friendly to People with Disabilities (PWDs). For example, structures, including comfort rooms must allow for wheelchair access. · The station must have enough provisions for safety and security · Fares must be affordable to the riding public. Discounts should be extended to students PWDs and senior citizens Unavoidable and Residual Impacts The following are the perceived unavoidable and residual impacts that may occur: · The increase in noise level during operation is mainly unavoidable but can be mitigated; · An increase in crime rates as a result of the influx of different kinds of people in and out of the stations is also unavoidable, but can be mitigated by providing a security force that will be visible at all stations. Local police force will be called on extreme scenarios; Page 282 240 · Although the operation of the LRT system will result into better vehicular traffic flow, influx of so many people alighting from the trains at any given time may cause traffic congestion, particularly when people do not use the street jumpers (pedestrian overpasses) that will be provided. 6 ENVIRONMENTAL MANAGEMENT PLAN 6.1 Constructions Contractor’s Environtment Program . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6-1 6.2 R-O-W Acquisition Procedures . . . . . . . . . . . . . . . . . . 6-1 6.3 Social Development Plan . . . . . . . . . . . . . . . . . . . . . . . 6-3 6.4 Resettlment Action Plan . . . . . . . . . . . . . . . . . . . . . . . . 6-8 6.5 Traffic Management . . . . . . . . . . . . . . . . . . . . . . . . . . . 6-11 6.6 Utilities Management Plan . . . . . . . . . . . . . . . . . . . . . . 6-19 6.7 Waste Management and Disposable Plan . . . . . . . . . . .6-20 6.8 Contingency Response Plan . . . . . . . . . . . . . . . . . . . . . 6-20 6.9 Abandonment Plan . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6-21 6.10 Envrinmental Monitoring Program . . . . . . . . . . . . . . . . .6-22 Page 283 241 6 ENVIRONMENTAL MANAGEMENT PLAN LRT LINE 1 CAVITE EXTENSION PROJECT Also known as Line 1 South Extension Project) 6.1 The project will be implemented on a public-private partnership through solicited mode under the Contract- Add and Operate (CAO) arrangement., LRTA will award the concession to the winning concessionaire which will be selected through an international competitive bidding.

Payments 50% down payment as soon as Deed of Sale is completed 50% balance, after the title of Ownership is transferred to LRTA 6.3 Social Development Program (SDP) 6.3.1 Objectives of the SDP Social development is best described as a process of planned social change designed to promote the well being of the population as a whole in conjunction with a dynamic process economic development (Middgley 1995, 25). Social analysis’ particular contribution to social development is the assurance that the Page 286 244 people – and their attendant capacities, values and needs – are placed at the center of the development process. Some of the aspects that are analyzed in the context of development intervention relate to: a. improvement or impoverishment of livelihoods; b. access to or exclusion from resources; and c. expansion of knowledge. After a thorough study of the history and present conditions prevalent in the areas if concern, the Community Relations Team of the Joint Venture Company conducted a rather extensive and exhaustive community immersion to validate the views of social analyst regarding squatter colonies. In view of the above, the ComRel Team of SNC-LRTA has culled a Social Development Plan relative to the planned development, the impacts on the informal settlers and its attendant mitigating measures to at least soften the impact on those who will be directly affected by the Project. Concomitant to this, the Social Development Program of SNC-LRTA will revolve around the following precepts: a. This plan is for the socially-disadvantaged communities where the alignment will pass through; b. The Proponent will provide an initial social to those impacted by the project; c. It will seek to stimulate self-reform through action-learning processes; and d. devise nascent social management partnerships between civic groups/networks. To fully realize the mission/vision of the Joint Venture Company with respect to its Social Development Plan, the company, through its ComRel Team will undertake the following objectives: General Page 287 245 a. To foster a positive, socially responsible and environment friendly corporate image for SNC-LRTA; and b. To build goodwill, trust and confidence between the Proponent and the various audiences and stakeholders affected by the Project, which can withstand periods of stress and conflict. Specific a. To undertake social Development projects/activities to be funded by the Proponent which will redoun d not only to the host community’s benefits, but the intermediate and larger environment as well. b. To formulate and execute the resettlement plan together with the affected stakeholders found along the alignment. c. To implement information activities that will project the positive contributions of Proponent and help mitigate whatever adverse effects the contributions of Proponent and help mitigate whatever adverse effects the Project may spawn. 6.3.2 Methodology Given the financial constraints faced by the national and local government institutions, conventional approaches to socialized housing can never replace self-help initiative in accommodating those who are not supplied by the market (Berner 1977,33). The important ingredient in this scenario is people’s active participation. Tapping local leaders among the squatter families, the ComRel Team will endeavor to maximize these individuals who are willing to volunteer their respective time and effort for the sake of their respective associations. The ComRel team will provide a mechanism that would weed out undesirable elements that may disrupt the process of social change among most of the relocates. Additionally, the ComRel Team will Page 288 246 conduct a series of training for a year and half with potential strategic structural change agents among the squatter families as target audience. It must be noted that “structures do not exist independently of people but are created, enforced, altered and reinforced by actual actors ( Smith 1989, 355). The basic premise of establishing strategic structural change agents is to transform quasi-groups with unrecognized common interest and goals of appropriation into strategic groups. The transformation of “quasi-groups” an sich (objectively existing) in the sense of Dahrendorf (1957) into groups fur sich (perceiving themselves as such) is a necessary condition for collective action integration, the emergence of a common lifestyle, increasing self-recruitment and the foundation of voluntary organizations ( Evers 1973, 114f; Evers and Schiel 1988,26f) may eventually result. With the assistance of the ComRel Team, strategic action will therefore ensure upon the establishment of an association composed of strategic structural change agents as representatives of the relocates/beneficiaries. They will embark on concerted group action to alleviate not just their current conditions but also plan and develop schemes by which they may be able to attain short and long term goals. Suffice it to say that the recruitment of change agents will not stop with the election of association leaders. A judicious search for potential leaders will be conducted on a regular basis. A conduct of leadership training at the grass roots level will also be facilitated. Further, the ComRel 6.3.3 Specific Activities Concomitant with the general objectives and thrust of the Social Development Program, the following activities will be accomplished within the next year and a half; a. Series of training on Social/Behavioral Change to be conducted up to the grassroots level; b. Coordination with both concerned national and local government offices and Non-governmental Organizations along Parañaque River certain Page 289 247 portions of the tributaries and easements of creeks found along Las Piñas and Bacoor) in a river/tributary revival movement. Thus efforts to assist this movement will be crucial in terms of Local government partnership; c. Organization of Settlers Associations; d. Inventory of affected properties and stakeholders and actual tagging (to avoid the mushrooming of settlements along the alignment); e. Establishment of a Grameen Banking system; f. Spiritual upliftment among relocates; g. Skill training; and h. Livelihood training for the establishment of micro-industries. Actual resettlement of displaced settlers will commence from fourth quarter of year 2008. A year and three months preparatory stage for the resettlement of displaced families will ensure that said families will be more than adequately equipped to become responsible homeowners who are prepared to pay off their respective amortization. In accordance with the Social Development Plan developed specifically for this alignment, the new homeowners, by end-year 2008, will have initially established certain micro- industries that will assist them in paying off the balance for their respective house loans. Consistent and in compliance with the Urban Development and Housing Act (UDHA) or Republic Act No. 7279, the proponent – through its Relocation Consultants, will coordinate with the local government unit heads, national housing agencies and financial aid only to the rightful settlers/beneficiaries. 6.3.4 Compensation Package A package that includes both disturbance and damage compensation for the displaced settlers will be given in accordance with existing Philippine Laws. Page 290 248 It should be noted that the list of recipients for this compensation package will still have to go screening by a Committee composed of the Association of Settlers, a Local Government Unit representative, Non-Governmental Organization, etc. The said Committee will go over the preliminary list and weed out professional squatters who may try to avail of the said package. This would ensure the delivery of the said financial aid to the rightful settlers/beneficiaries 6.3.5 Livelihood Assistance Most of the beneficiaries of the social development and resettlement programme of the live either in relative or absolute poverty. Assistance in drawing-up livelihood projects will be conducted by the Proponent. The ComRel Team will facilitate networking with national agencies such as the Department of Social Welfare and Development, Department of Labor and Employment, Department of Trade and Industry, Design Center of the Philippines, etc. for possible livelihood projects. The Comrel Team will also tap grants for possible socio-economic endeavors. Skills training in coordination with the Technical and Educational Skills Development Administration (TESDA) will be scheduled before the construction of the LRT Project so that qualified stakeholders may be able to avail of employment opportunities from the Project. 6.4 Resettlement Action Plan Since self-help initiatives have been found to be theoretically and empirically feasible and effective means that will ultimately break the vicious cycle of squatting, the participatory approach is deemed as a positive step towards the full implementation of a resettlement action. It should be noted that the stakeholders have always been encouraged by the LRTA Consultants to ventilate their concerns and act on them at the soonest possible time if such issues are deemed urgent. Page 291 249 The action plan adopted by the Joint Venture Company will put emphasis on the strengthening of association groups, rather than resort to the usual “dole-out” system. The Social Development Programme developed by the LRTA Consultants will hopefully discourage mendicancy among the stakeholders. It will seek to empower the stakeholders so that they may be able to chart their future and trek the better way towards poverty alleviation. The Proponent will focus more on social development efforts that will inculcate in the minds of the resettled stakeholders the value of acquiring their respective home lots. Additionally, the Proponent shall initiate self-reliance activities among the stakeholders. This means that the Proponent will conduct seminars/workshops in coordination with national agencies that have the expertise in livelihood projects and skills training. Proponent will also work towards facilitating the integratation of resettled groups in their new environment by consulting with the future host communities Land acquisition has been identified as the most crucial task that the association must endeavor to facilitate. Figure 6.1 illustrates how this activity will be undertaken. Table 6.2 shows the timeframe for relocation. 6.5 Traffic management 6.5.1 During Construction The construction of the LRT1 Extension will affect various roads and highways. The major affect will be caused by construction and will be temporary. In a few instances, however, the guideway will be located within, and require permanent modification of, existing roadways. The impact on roads and traffic will fall into the following main categories. · permanent road modifications to accommodate guideways columns; Page 292 250 · temporary traffic restrictions in streets where guideways will be constructed; · general construction traffic movements for delivering construction materials and equipment, and removing excavated and waste materials; and · special traffic movements for delivering the guideway superstructure box- beam girders from the precasting facility to the erection locations along the guideway. Special traffic movements will be planned well in advance with the appropriate authorities, and arranged to minimize their impact on traffic. Where necessary, such movements will occur at night. General construction traffic movements will also be planned in advance to minimize their impact, and will be timed for off- peak traffic periods as far as is practicable, and at night where necessary. The most significant impact will be where the guideway is constructed in existing roads. Guideway substructure piling, pilecaps, columns and crossheads will be built at approximately 30-meter intervals along the alignment, and the precast concrete box-beam superstructure girders will then be erected. The construction activity will include: · installation of between 6 and 1 2 large diameter bored piles at each column, including placing piling concrete and reinforcement, · excavations in the order of 9 m x 9 m x 3.5 m deep, with trench sheeting support, for pilecap construction at each column; · placing of formwork, reinforcing steel and concrete for pilecaps, then backfilling the excavation; · erecting reinforcing cages, formwork and bearings for columns and crossheads, placing concrete, then removing formwork; · erection of superstructure girders; Page 293 251 · road restoration. In some locations, particularly where working space is restricted, a single large (approximately 3 m diameter) caisson foundation may be preferred to the traditional piles and pilecap construction. Management of Roads Affected by Guideway Construction The roads that will be directly affected by ghuideway construction are as follows: Redemptorist Road: The guideway will run along the south curb lane of Redemptorist Road between Taft Avenue and Roxas Boulevard. The road will be permanently reduced from four to three traffic lanes to accommodate the guideway columns, as indicated on Figure 1.2 However there are plans to convert Redemptorist Road into a pedestrian mail with one traffic lane for private vehicles. The street vendors stalls along the south side of Redemptorist Road will have to be temporarily relocated prior to construction. It is envisaged that the superstructure girders in Redemptorist Road will be erected using a longitudinal launching methodology due to the limited space available for operating cranes. For safety reasons, traffic will not be permitted to travel beneath the operating launchers and the same traffic restrictions will apply for both the substructure and superstructure construction. The roadway will be reduced to two traffic lanes as indicated in Figure 6.2 for approximately 14 weeks during guideway substructure construction, and for approximately 15 days during erection of the superstructure girders. These periods may be sequential or separated by a period of time, depending on the detailed construction schedule developed. Page 294 252 Work will be arranged to minimize impact on the commercial premises along the north side of Redemptorist Road and to ensure access is always available to the Mother of Perpetual Help Church. Roxas Boulevard Crossing: The guideway will curve over Roxas Boulevard from Redemptorist Road and then run south along and outside the west side of Roxas Boulevard. A guideway column will be located in the service road divider island of Roxas Boulevard. Roxas Boulevard will be permanently reconfigured slightly at this location as necessary to accommodate the column. Roxas Boulevard will be reduced to three traffic lanes in each direction for approximately three weeks during construction of the piled foundations, pilecap, column and crosshead. It is envisaged that the guideway superstructure girders across Roxas Boulevard will also be erected using the launching method, and in two staged. Firstly, the southbound lanes will be closed, traffic will be diverted into the northbound lanes with two lanes one way and one lane the opposite way. The northbound lanes will then be closed for one night and traffic re-routed to the southbound lanes to complete the superstructure erection across Roxas Boulevard. No other major impacts are expected to Roxas Boulevard, as the guideway running south form the crossing at Redemptorist Road will be outside the Roxas Boulevard right of way. Coastal Road Bridge Crossing: The guideway will run along and outside the west side of the Roxas Boulevard before curving over that highway at the Parañaque River. The guideway is expected to clear span the Coastal Road Bridge at the Parañaque River, and not to affect the roadway Page 295 253 itself. The roadway will, however, be closed for one or two nights during erection of the guideway girders. Ninoy Aquino Avenue: After leaving the Parañaque River bank, the guideway will run along the centre median of Ninoy Aquino Avenue until Dr. Santos Avenue. The guideway columns will be located within the existing centre median, and the street lighting columns will be relocated form the centre median to each side of the road. Trees affected by the guideway construction will be relocated in advance. The total length of guideway along Ninoy Aquino Avenue will be approximately, one kilometer. To Limit the traffic disruption, the guideway substructure will be constructed in a series of “rolling” construction operations, in approximately 500m sections. These sections will require work site approximately 12 meters wide by 550 meters long, plus areas at each end to accommodate traffic diversion taper lengths. To accommodate this, the road will be temporarily widened to maintain two traffic lanes in each direction over the length of the construction section, as indicated in Figure 6.3 . Substructure construction in each section will take approximately 16 weeks to complete. As the substructure is completed in each section, that part of the road will be restored and the work site and construction operations will move to the next section. The superstructure beams will be installed sequentially along the completed substructure using the launcher placing system. This again will involve a rolling sequence of work sites and traffic restrictions to provide safe working space. Approximately four beams will be erected each day and each work site will involve a lane closure in each direction for a distance of 100 m plus transition. Tapers at each end. Beam erection along Ninoy Aquino Avenue will take 4 weeks to complete. Page 296 254 Dr. Santos – Talaba Diversion Road There are no existing roads along this 5-Kilometre section of alignment. Temporary roads and water crossings will have to be designed and built to accommodate the movement of construction equipment along this stretch of the guideway. The beams for the superstructure will continue to be erected linearly southward from Dr. Santos Station. Tramo Road Crossing : The guideway is expected to clear span over Tramo Road and the substructure construction should not affect traffic on the road. The road will, however, be closed for one night to erect the guideway beams. Quirino Avenue Crossing : The guideway is expected to clear span over Quirino Avenue and the substructure construction should not affect traffic on that road. The road will, however, be closed for one night to erect the guideway beams. Talaba Diversion – MCCR Link Road Crossing: The guideway is expected to clear span over the TAlaba Diversion – MCCR Link Road and the substructure construction should not affect traffic on that road. The road will, however, be closed for one night to erect the guideway beams. A traffic plan to divert traffic through this area will be designed and approved prior to the closure. Talaba Diversion Road: Page 297 255 The guideway will run along a new center median in the Talaba Diversion Road between approximately Real Street and the General E. Aguinaldo Highway. To accommodate the guideway columns, the road will be permanently widened by three meters on its east side and have a new center median constructed. During substructure construction, the road will be reduced to one-traffic lane in each direction for approximately 20 weeks , as shown in Figure 6.4a . A possible traffic re-routing plans is shown in Figure 6.4b . Guideway superstructure girders are expected to be installed using the launching method and at a rate of four girders per day in a rolling construction sequence along the road in approximately 100 m sections. To accommodate this, the road will be reduced to one-traffic lane in each direction over the length of each construction section, plus area at each end to accommodate traffic tapers. It will take approximately 21 days of such localized traffic restrictions to erect all of the girders along Talaba Diversion Road. General E. Aguinaldo Highway Crossing: The guideway is expected to clear span over the General E. Aguinaldo Highway. Constuctin of the northern substructure for this crossing will take place during the 15- week lane closure for substructure construction along the Talaba Diversion Road. Construction of the southern substructure will not affect traffic along the highway, although the highway will be closed for one night during the erection of the guideway beams. A traffic plan to divert traffic through this area during the beam erection will be designed and approved prior to the closure. The plan will ensure uninterrupted access to the hospital. A Traffic Management Plan for each of the work will be prepared and agreed with all applicable authorities prior to affecting traffic in that area. The following principles will be followed in the preparation of Traffic Management Plans: · vehicular and pedestrian traffic will be managed in a safe and efficient manner; · safety of the general public and work crews will be paramount;, · staging strategies and timing of work will be set to maintain flows Page 298 256 · with minimal disruption to peak-hour traffic; · night activities will be used to minimize impact on traffic; · work zone protection and isolation will be achieved using barriers and screens; · traffic diversions will be arranged, sign posted and publicized in advance to avoid causing confusion to motorists; and · roadway and traffic alterations will be engineered and approved in advance; and flexibility and responsiveness will be built into all plans. The Traffic Management Plans will address all pertinent issues, such as: · work site extent, duration, access and egress arrangements for construction in roadways; · vehicular traffic lanes that will be maintained for public use, and temporary traffic diversion arrangements; · public and construction safety provisions, including flagging, barriers, hoarding, signage and lighting; · diversion of traffic to adjacent roads/streets to reduce traffic volumes within the construction area; · construction traffic routes and movements to and from the work site, and procedures and timing for any special traffic movements, such as pre-cast concrete guideway girder deliveries; · public information measures via posted notices and the media. The program Management Office will start the traffic planning process during the Preliminary Design Phase, and will establish an inter-active dialogue and communication with the authorities having jurisdiction over roads and traffic. The Program Management Office will produce and obtain approval for detailed Traffic Management Plans during the detailed design and construction phases. 6.5.2 During Operation Page 299 257 The provision of major intermodal facilities as part of the overall project layout, will provide smoother traffic flow of buses and jeepneys through the station site and to/from adjacent streets (Please refer to Figures 6.5 a-e ). As mentioned in Section 2.4.1.6 of this EIS document, salient features of the intermodal facilities include: a) Unloading and loading of bus and jeepney passengers within the intermodal facilities rather than on adjacent streets will prevent disruption and impedance of traffic flow along adjacent streets; b) Stations along Roxas Boulevard ( Redemptorist, MIA, and Asia World ) are located adjacent to the planned bus terminals o the PEA, which will facilitate the transfer of passengers between buses and jeepneys; c) Las Piñas and Ninoy Aquino Stations will be provided with on-site facilities for smooth transfer of passengers between the Extension and buses and jeepneys; d) Pedestrian crossovers will be provided at Redemptorist, MIA, and Asia World Stations to avoid traffic disruption from pedestrian crossings; e) Traffic regulation shall be in coordination with the MMDA. For stations along existing highways/roads, frontage control through improvement of sidewalks, limitation of parking, loading and unloading, and otheractivities along the roadside, shall be implemented to ensure safety of pedestrians and avoid other types of roadside friction. 6.6 Utilities Management Plan An examination of available utility plans for the guideway alignment was undertaken to assess the impact of utility relocation, protection and abondoment Page 300 258 measures. A schedule of these major services and the proposed method of addressing conflicts have been prepared and available for submittal if necessary. The major features of these are: · The Overhead Transmission Lines along the proposed alignment , 34.5 kV, 115 kV and 230kV, which will require relocation, avoidance or protection. · Any and all underground utilities (sewer, water) that would require relocation – specifically along Redemptorist Road, NInoy Aquino Avenue and Las Piñas / Talaba Diversion Road. Detailed plans will be developed for the management of all existing utility services along the guideway alignment during the Preliminary Design Phase. These will be prepared in consultation with, and agreed by, the applicable utility authorities. The utility management plans will be developed using the following principles: · everything possible will be done to avoid conflict with major utility services; this will include the guideway alignment adjustments and locating columns and footing where practicable to avoid major serevices, and adopting construction methodology to support and protect major services in place; · for unavoidable major utilities conflicts will be relocated or diverted in advance of guideway construction wherever possible; · minor utilities conflicts will be relocated or diverted in conjuction with the construction of the guideway works. · The timing and execution of utility relocationsand diversions, and in particular for major utilities, will be selected to minimize impact to those served by the utility; · the goal will be to find cost efficient solutions that can minimize impact to utilities and those served by them. The Program Management office will start the utility management planning process during the Preliminary Design Phase, and will establish an inter-active Page 301 259 dialogue and communication with the authorities and companies having jurisdiction over utilities. The Program Management office will produce and obtain approval for detailed Utility Management Plans during the detailed design and construction phases. 6.7 Waste Management and Disposal Plan The Proponent shall submit a waste management and disposal plan to the DENR for approval prior to the implementation of the project. 6.8 Contingency Response Plan 6.8.1 During Construction (i) Adequate warning signs, barricades, warning lights including traffic aides must be provided at all times during constructions; (ii) The Contractor must be required to provide vehicles for emergency cases. (iii) Proper handling of garbage that may be excavated from the Manuyo area to avoid ground water contamination; (iii) The Contractor will also be required to implement the following: · Adopt appropriate construction procedures; 6.9 Abandonment Plan Abandonment measures must be implemented after the construction activites. Upon completion of the project, all parties concerned, such as the LRTA, the DENR, and the LGUs m ust inpesct the area to check if: Page 302 260 temporary structures, if not usable anymore are dismantled, and stockpiled materials are property disposed of; interrupted power and water service connections are properly re-installed, and in the usual functioning condition; construction equipment and used materials are transported back to the constractors; and temporary camp of the construction workers and facilities are cleared of debits; The proponent must continuously implemented maintenance activities to preserve and restore the existing infrastructures in good operating conditions. An abandonment phase is not envisioned at this point. 6.10 Environmental Monitoring Program 6.10.1 Monitoring Activities The following activities will be monitored during the Construction Phase : (i) Implementation of approved plan/program on structural, drainage, Waste disposal, TSP control, noise pollution control, tree cutting, etc. (ii) Implementation of MMDA Approved Traffic Management Plan (including Traffic Rerouting Plan) Page 303 261 (iii) Assigning of traffic aides, particularly at existing busy roads such as Redemptorist, Tramo, Talaba Diversion Road, and others; (iv) To minimize the dust build-up, water trucks equipped with water spraying equipment must be on stand-by, particularly in highly populated areas in Brgys. Baclaran, La Huerta, Pulang Lupa, Manuyo, Zapote, and Talaba; (v) Conduct of air quality and noise level sampling. The parameters to be measured are STP and noise. Monitoring stations will be located on construction sites that are near settlement areas (i.e., Brgys. Baclaran, La Huerta, Pulang Lupa, Manuyo, Zapote, Talaba). Noise level monitoring must be conducted more frequently in construction areas near schools, hospital and churches (i.e., Baclaran church, San Nicolas Church, La Huerta Elementary School, Las Piñas Elementary School, Talaba Elementary School, St. Dominic Hospital); (vi) Water quality along the waterways.
