Recently, the number of ecological restoration projects at waterbodies have increased significantly and applied in many areas. Many researchers have been working on large-scale restoration projects with some complex variables and considerations involved, but only few are focused on small-scale projects. The purposes of this study are: (1) to evaluate and monitor the ecological restoration projects at Barclay City Park, Tainan City, Taiwan R.O.C, by using Post Project Appraisals (PPAs) and compare with several city parks in Bandung, Indonesia; (2) to promote an ecological approach that incorporates public perceptions into city parks restoration projects in Bandung City, Indonesia, to determine the environment-friendly constructions that provide long-term benefits to the ecosystem. The data were collected by kick samplings and used following the Before-After-Control-Impact (BACI) method. We sampled and analyzed seven water quality parameters, including temperature, electrical conductivity, salinity, pH, dissolved oxygen, and so on, at several sections, and then identified the aquatic habitat within. The results showed that water quality condition was still unclear with limited ecological value. The study also identified that the degraded water quality condition has increased the public awareness. Therefore, the application of sustainable ecological projects in urban drainage systems could also improve the aesthetic value in the context of urban landscape and gain growing public interest due to its positive effects on water quality and quantity issues. Furthermore, the study recommended water quality monitoring and public hearings programs. Further recommendation is the principles of ecological effectiveness, methodological and economic efficiency, and sociocultural engagement, which should be interwoven in the application of the guidelines and the framework for planning and implementing ecological restoration.
