Stormwater Management Permits

Stormwater management (drainage) systems for new construction projects and redevelopment require environmental permits from the Department of Environmental Protection (DEP) or Water Management Districts (WMD) and local regulatory agencies. Regulatory criteria established by the agencies are set to provide adequate flood control (water quantity) and remove sediment and pollutants from storm runoff (water quality). Structural components of drainage systems may include storm drains, street gutters, weirs, dams, pumps, exfiltration trenches and drainage wells. A combination of these components, in conjunction with non-structural elements such as grading and vegetation, are typically used in the design of a stormwater management system to meet both water quality and water quantity criteria.
