LAMC 64.72 (LID Ordinance, Ord. 183833) requires new development to manage stormwater runoff on-site through infiltration, bioretention, or capture systems. Priority projects must meet MS4 permit standards using the Development BMP Handbook. Projects disturbing 1+ acres need a state SWPPP. Grading permits are conditioned on stormwater compliance and a recorded covenant.
Los Angeles enforces stormwater management regulations to prevent flooding and protect water quality. New construction and major renovations must include stormwater management plans. Impervious surface limits may apply in residential zones. Low-impact development techniques like rain gardens, permeable pavers, and bioswales are encouraged or required. Erosion and sediment control plans needed during construction. Post-construction stormwater facilities must be maintained by property owners. Municipal separate storm sewer system (MS4) permits govern city-wide discharge.
Failure to implement stormwater plan: stop-work order. Illicit discharge to storm drains: fines $500 to $10,000. Maintenance failures: notice and fines after non-compliance.
