Using Rainwater to Grow Livable Communities. Sustainable Stormwater Best Management Practices (BMPs). Basic Principles. Treat water as a resource, not a waste product Design to mimic or replicate the natural hydrology of a site
Best Management Practices (BMPs)
Raingardens are bioretention areas that increase infiltration, recharge groundwater, and improve overall water quality
McCarthy Garden in Kansas City
An ecoroof is a roof that is planted with vegetation. It can reduce the heat imprint of a building and reduce off-site runoff
Detention and infiltration areas reduce the amount of off-site runoff and the speed with which water enters local waterbodies

Street right-of-ways can be modified to capture runoff from roadways
Green Street Swales - New Seasons Market
Detention areas, planted with native plants, perform a stormwater retention and water quality improvement function.

The Philadelphia Public Works Department is a partner in the Pennsylvania Horticultural Society's Neighborhood Transformation Initiative, which transforms vacant lots into community-friendly spaces.
Converted spaces offer stormwater management benefits because the park-like spaces are outfitted with berms and swales that collect and infiltrate rainfall and runoff, and natural vegetation promotes evapotranspiration.

A Regional Stormwater Management Quality Program was developed in response to TMDL and NPDES Phase I permit requirements
Program components include:

Seattle Public Utilities has projected that its Natural Drainage Installations are at least 25 percent less expensive than traditional stormwater systems due to decreased build and infrastructure maintenance costs.
