Sustainable Funding for Philly’s Green City, Clean Waters Plan

Sustainable Funding for Philadelphia’s Green City, Clean Waters Plan

The City of Philadelphia adopted the Green City, Clean Waters (GCCW) plan in 2011 as part of its regulatory obligation under the Clean Water Act to reduce pollution resulting from combined sewer overflows. The 25-year plan envisions the City implementing approximately 9,564 greened acres (GA) (34% of the combined sewer impervious areas) with green stormwater infrastructure (GSI), which along with other stormwater practices will capture 85% of baseline annual wet weather flow into the sewer system. The plan represents a transition from managing stormwater based solely on a gray infrastructure system to managing stormwater through a hybrid system that incorporates both gray and green infrastructure.

WaterNow contributed to this report, completed with support from the William Penn Foundation, that considers the sustainability of the funding and financing strategies that support reaching the target set out in the GCCW plan for the City’s hybrid stormwater management system, with specific focus on private non-residential land and non-City owned public land.
