Post-Construction Stormwater Management

Bioretention Drain

Development and redevelopment by their nature increase the amount of imperviousness in the surrounding environment. This increased imperviousness translates into loss of natural areas, more sources for pollution in runoff, and increased flooding risks.   Municipal Separate Storm Sewer (MS4) jurisdictions must have a program to require developers to install and maintain post-construction stormwater controls to reduce these impacts.

integrated Stormwater Management (iSWM™) Program for Construction and Development The iSWM Program for Construction and Development is a cooperative initiative that assists cities and counties to achieve their goals of water quality protection, streambank protection, and flood mitigation, while also helping communities meet their construction and post-construction obligations under state stormwater permits.

The iSWM Criteria Manual for Site Development and Construction contains criteria that cities and counties may adopt as a component of their stormwater management related development regulations. The iSWM Technical Manual provides the technical details to meet the requirements established by each community in their locally adopted iSWM Criteria Manual.
