Garden Grove regulates stormwater runoff under Municipal Code Title 14 and the Orange County NPDES MS4 Permit. New development and significant redevelopment must incorporate best management practices to prevent polluted runoff from reaching storm drains, channels, and ultimately the Pacific Ocean.
Garden Grove enforces stormwater management under Municipal Code Title 14 (Water and Sewers) and as a co-permittee under the Orange County NPDES Municipal Separate Storm Sewer System (MS4) Permit issued by the Santa Ana Regional Water Quality Control Board. All new development and significant redevelopment projects must prepare a Water Quality Management Plan (WQMP) incorporating site design, source control, and structural treatment control BMPs. Projects disturbing one acre or more require a Construction General Permit and must file a Stormwater Pollution Prevention Plan (SWPPP). Low Impact Development (LID) strategies such as bioretention, permeable pavement, and infiltration are required where feasible. It is unlawful to discharge or cause to be discharged any non-stormwater substance into the municipal storm drain system. Common prohibited discharges include wash water, pool drainage, paint, oil, pesticides, and sediment. Construction sites must implement erosion and sediment controls, track-out prevention, and proper material storage.
Illicit discharge violations are enforced by Garden Grove Code Enforcement and Public Works. Violations of the Municipal Code can result in administrative citations and fines. State NPDES violations may carry penalties up to $10,000 per day. Contact Public Works at (714) 741-5375.
