Construction sites have the potential to cause significant impacts to downstream receiving waters as well as storm drain infrastructure if not properly managed. TPDES Municipal Separate Storm Sewer System (MS4) Permits require MS4 cities and counties to regulate private construction activities within their jurisdictions. In addition, all local governments in Texas must obtain coverage under the TPDES Construction General Permit for any municipal construction activities that disturb one or more acres.

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.
