【 摘 要 】

Depok City is one of the capital cities in Jakarta and has a very large population. This resulted in the lack of green open spaces due to the transfer of the function of land use into settlements. This eventually results in excess surface water runoff during the rainy season and reduction on groundwater reserves during the dry season. At present, it still applies the conventional drainage system, so the potential flood becomes high because dimension of drainage channel is too small to manage rain water well and avoid flood disaster. The aim of this research is to study policy evaluation of runoff, erosion and flooding to drainage system in property Depok City, Indonesia. The result of the research shows that the public perception about the runoff, erosion and flooding policy evaluation property in the framework of green property which is passably with 42.4% is good. The research on the evaluation of the property policy obtained information that the runoff process on the property construction is stated quite influential on the change of structure of the soil and flooding.
