Permits

CRWD issues permits to ensure stormwater runoff from development projects does not negatively impact the District’s lakes, rivers and wetlands. Impervious or paved surfaces on new development projects generate large volumes of runoff that may contain oil, salt, dirt, bacteria and trash, all of which contribute to poor water quality in CRWD. Water quality and stormwater management rules adopted by our Board of Managers in April 2015 govern all CRWD permitting requirements. The Permitting Program regulates construction sites that are more than one acre. CRWD requires erosion and sediment control during construction and installation of Best Management Practices (BMPs) to treat runoff after construction.
