Abstract: The aim of this study is to provide a methodology for the facility site selection, applying spatial and multi-criteria analysis and to suggest an optimal location in study area for a sustainable large-scale facility. The 5 candidate sites of study area are evaluated and compared under both quantitative and qualitative factors from the analysis results of Geographic Information Systems (GIS) and Analytical Hierarchy Process (AHP) to identify suitability of facility location. The public survey is conducted for experts and residents on preference of site location in order to endorse the proposed site. This site selection model can be useful to planners and designers seeking to choose locations where new public facility will best integrate into the surrounding environment.
