In this paper, a planning analysis of implementing low impact development (LID) type of stormwater best management practices (BMPs) for land subsidence area runoff control is presented. A case study is the Yunlin Kouhu Township (YKT) in Taiwan. BMP is a best management practice (BMP) planning and analysis tool, which is capable of simulating BMP performance BMP placement and design. The Storm Water Management Model (SWMM) was used to simulate LID-BMPS for the YKT. Optimization analysis for BMP design aimed at achieving either runoff control was then conducted. The results were used to form recommendations to the YKT for modifying the present stormwater management system in order to achieve more runoff control strategies. The YKT strategies of stormwater system incorporated some LID BMPs such as green roofs, porous pavements and rainwater cisterns.
