Philadelphia has one of the nation's most ambitious stormwater programs. Phila. Code §14-704(3) authorizes the Philadelphia Water Department's stormwater regulations, requiring Post-Construction Stormwater Management for earth disturbances of 15,000+ sq ft (5,000+ in Darby/Cobbs Creek). The Green City, Clean Waters program is a 25-year, $2.4 billion investment in green infrastructure.
Philadelphia enforces stormwater management regulations to prevent flooding and protect water quality. New construction and major renovations must include stormwater management plans. Impervious surface limits may apply in residential zones. Low-impact development techniques like rain gardens, permeable pavers, and bioswales are encouraged or required. Erosion and sediment control plans needed during construction. Post-construction stormwater facilities must be maintained by property owners. Municipal separate storm sewer system (MS4) permits govern city-wide discharge.
Failure to implement stormwater plan: stop-work order. Illicit discharge to storm drains: fines $500 to $10,000. Maintenance failures: notice and fines after non-compliance.
