Introduction The Payatas Scavengers Homeowner!s Association (PSHAI)1 started as one of the savings groups in Payatas in the early 1990s organized by the Vincentian Missionaries Social Development Foundation (VMSDF). At first, they saved for their social and economic needs, start-up capital for livelihood projects, hospitalization bills, education needs of their children, etc. In 1995, they began to save for land and housing with the goal of buying a titled property where they could build their houses in the future and live without the fear of being evicted. PSHAI was formally organised in 1998, composed of members of the savings groups who committed to contribute their individual savings and to pay monthly amortization to purchase a titled lot in San Isidro, Rodriguez where they would build their houses. PSHAI named their housing project site as “Miraculous Hills Subdivision”. PSHAI bought a 30,000-square meter lot in San Isidro, Rodriguez in December 1998. This was two years before the dump-slide disaster in Payatas in July 2000. It was the first community-led land acquisition effort through the Homeless Peoples! Federation of the Philippines (HPFPI) savings scheme. The members used their three-year savings as down payment for the lot and accessed a low-interest loan from the Domus-Mariae Foundation2 for the full payment. They are still repaying the loan in monthly amortization of PhP 540 per member.3 Although the development of the site was to be self-financed mainly by the members, the construction of two row houses, the opening and concreting of the road and the construction of an activity center were fast-tracked in 2001 through the VMSDF and HPFPI to provide decent shelter for some families displaced during the Payatas dump-slide disaster.4 PSHAI, with HPFPI assistance, is the developer of their housing project. Without prior experience or knowledge on land acquisition or housing-related government processes, PSHAI learned their way as they navigated levels of bureaucratic requirements and procedures. Because of this participatory and community-led approach of PSHAI, the association is identified as one of the sites (in the Philippines) for the Pro-Poor Eco- Settlement Demonstration Project of the UN-ESCAP. The Demonstration Project of the UN-ESCAP called, “Eco-Efficient and Sustainable Urban Infrastructure in Asia and Latin America” seeks to develop a set of principles, guidelines, and strategies for policy-makers and planners to develop eco-efficient and sustainable urban infrastructure. It also aims to merge eco-friendly options for housing, infrastructure, services, and livelihood provision that are affordable to the poor (and therefore replicable) with participatory and community-led management. Parallel to the UN-ESCAP research work is the implementation of the Community-led Infrastructure Facility Financing (CLIFF) housing project. Initially, 70 families are targeted each year to benefit this project. The project would run for five years and is expected to have served most of PSHAI members. 1 PSHAI now has 264 members. In 2006, PSHAI opened the membership in the housing association to urban poor families that are interested in saving for a lot even if they are not original members of their savings program. 2 Domus-Mariae Foundation is a non-profit organization assisting the urban poor to acquire low-cost housing. 3 The monthly amortization also covers miscellaneous expenses that are incurred in the processing of bureaucratic requirements. Aside from this, the members also contribute PhP 50 a year for their annual property tax. 4 The costs of these infrastructures are to be repaid by the PSHAI members in the future. 4 2. Miraculous Hills Subdivision, Barangay San Isidro, Rodriguez 2.a. Physical The Miraculous Hills Subdivision is located at Barangay San Isidro, Rodriguez, Rizal, which approximately lies at 140 45! 35” N and 1210 09! 40” E. The site forms part of the lowland section of the Puray Watershed that originates from the southwestern mountains of Sierra Madre. Puray River then joins the Tanog River and the single channel flows to the Wawa River that drains into the Marikina River then discharges to Laguna de Bay. The subdivision has total area of about 30,000 square meters and is approximately three kilometers away from the town proper of Rodriguez. The major roads are well paved and fairly maintained while minor roads are combination of compacted earth- soils and stones. Generally, the topography (Map 1) of the Miraculous Hills Subdivision is gently rolling
