Basic Principles• Treat water as a resource, not a waste product
• Design to mimic or replicate the natural hydrology of a site
• Design to address issues of water quality, quantity and amenity
• Accommodate the standards and expectations of the local community
• Infiltrate, detain, retain
• Start small, build from there
• Collaboration is key

Rain Gardens: Kansas City, MO
Raingardens are bioretention areas that increase infiltration, recharge groundwater, and improve overall water quality

Ecoroof: Chicago, IL
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:Belleview, WA
Detention and infiltration areas reduce the amount of off-site runoff and the speed with which water enters local waterbodies
High flow storage area next to recreational facilities

Reduce Runoff: Burnsville, MN
Monitoring has shown that
• The rain gardens in the Burnsville rain garden demonstration project capture at least (and often more than) the first 0.9” of rainfall
• There is a 90% reduction in runoff rates from the neighborhood with rain gardens as compared to a similar neighborhood without rain gardens

Add Amenity: Philadelphia, PA
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.
Vacant lot at 2300 North 3rd Street before greening
Site was regraded to capture stormwater and planted with trees, shrubs, and grass

Meet Regulations: Truckee Meadows, NV
A Regional Stormwater Management Quality Program was developed in response to TMDL and NPDES Phase I permit requirements
Program components include:– Structural BMP Controls
– Land Use Planning and LID Tools
– Public Outreach
