Water Sensitive Urban DesignSTORM
STORM is a simple computer-based program that enables decision makers to evaluate whole-of-site performance of stormwater quality treatment strategies for small-scale developments. The tool is able to display the amount of treatment typical WSUD measures will provide in relation to best practice targets. A STORM rating of 100% signifies achievement of the stormwater quality performance objectives: 80% reduction of suspended solids, 45% reduction of nitrogen and phosphorus.
