A web-based tool implemented by the Philadelphia Water Department to educate its customers and help them explore ways to reduce their stormwater impact. A part of Green City, Clean Waters, Philadelphia’s 25-year plan to transform the health of the City’s creeks and river by reducing pollution impacts and improving natural resources, the app turns any commercial property into an online canvas where customers can sketch out stormwater remediation strategies and access a host of information to help them take important next steps.
