Various studies show a close relationship between imperviousness and various biotic/abiotic elements of aquatic ecosystem. This phenomenon has been adapted to assess the water-sensitivity of a regional spatial plan at regency/city level. A generic assessment procedure based on the experience in Upper Ciliwung watershed is ready for application in other regions. The objective of this study is to apply the assessment procedure in set of subwatersheds, which covers all stream classifications, as specified in the reformulated impervious cover model. Using family biotic index as indicator of aquatic ecosystem quality, water quality index and habitat score as dependent variables, and impervious cover as independent variable, the regression equations are derived based on the data of 17 subwatersheds of Ciliwung watershed with imperviousness ranges of 5.23-91.10%. Based on the assessment result an outline of restoration plan can then be developed.
