The Department of Environment and Natural Resources (DENR) declared the closure of all remaining illegal dumpsites in April 2021, freeing up 1,174 land for future urban uses. Despite the legal mandate for dumpsite conversion, local government units have not yet incorporated post-closure land use into their planning agenda. Additionally, the framework for dumpsite conversion is non-existent, so this study aimed to establish the conditions for dumpsite brownfield redevelopment by engaging stakeholders in a local area sample where expert and council decision-makers addressed the three major concerns on dumpsite conversion, namely, information requirements, site attributes, and land uses. The research method adopted was the Multi-Criteria Decision-Making Analysis (MCDA) as it accounts for the physical and socio-economic qualities of the land, as well as the diversity of perceptions of land potential among different decision-makers. The preference for available information in assessing the site, the attributes that make a dumpsite suitable for redevelopment, and the matching of site attributes with possible land uses were assessed on a five-point Likert scale. The site attributes were organized under each land use to establish a definite criterion for redevelopment, and project options were shown to verify the decision-makers' previous land use choices. The preference for information requirements was ranked and analyzed based on their content and coverage using measures of central tendency and dispersion. However, due to the lack of benchmarks for dumpsite redevelopment, the site attributes were assessed subjectively by decision-makers. This is the fuzzy part of the study where the weights and rankings were calculated using Fuzzy TOPSIS and Kendall's Tau b for rank correlation. Finally, measures of central tendency and Kendall's Tau b Rank Correlation were employed to investigate the decision-makers' preferences for land use and project options. The results indicate that expert decision-makers view 'permit/approval for dumpsite redevelopment as the most important information for redeveloping dumpsites. This information requirement is related to site conditions such as soil bearing capacity, slope stability, and other intrinsic site characteristics. Although expert decision-makers perceived that dumpsite conversion is the responsibility of the DENR, council decision-makers argue that the Department of Public Works and Highways (DPWH) should be the lead agency, with 'building permit' as the most important information requirement. This information requirement involves construction technology, building occupancy, and standards on siting and material quality, among other factors. The research findings can guide the decision-making process in identifying the site criteria and the appropriate land uses for converting dumpsites in our country. According to all decision-makers, the economic and extrinsic physical site attributes are equally important considerations for redeveloping dumpsite brownfields. However, they believed that the site's social attributes were important for institutional and recreational land uses, while economic attributes were significant for commercial and industrial land uses. Only in the case of open space did decision-makers indicate that intrinsic physical attributes were an important consideration. In conclusion, decision-makers recognized the advantages of dumpsite brownfield redevelopment, with industrial and institutional land uses as the preferred post-closure land uses for the study area.
