Environmental Protection Pennsylvania 3 Minutes Read · published February 05, 2026 Flag of Pennsylvania

Philadelphia, Pennsylvania faces recurring urban flooding where runoff overwhelms sewers and streets. This guide explains local runoff controls, how they relate to Philadelphia municipal rules, and practical steps for property owners, developers, and contractors to reduce flood risk and comply with city requirements.

Overview of Runoff Controls

Philadelphia requires stormwater management for new development, substantial redevelopment, and certain construction activities to control runoff volume and peak flow and to promote infiltration and reuse. Controls include green infrastructure, retention/detention, and source controls tied to Philadelphia Water Department standards and the municipal code. For official design standards and plan submittal rules, consult the city guidance and code pages below. Stormwater Management[1]
