Redondo Beach, CA Environmental Rules: Stormwater Management (2026)

The City is a co-permittee under the Los Angeles County Municipal NPDES Permit and enacted Chapter 7 of Title 5 to satisfy that permit's requirement to prohibit non-stormwater discharges into the municipal separate storm sewer system (MS4). 109 makes it unlawful to establish or maintain any illicit connection or illicit discharge to the MS4, bars littering into streets, storm drains, catch basins or any fountain, pond, lake or stream, and prohibits disposing of leaves, dirt or landscape debris into the system. A detailed list of prohibited non-stormwater discharges follows, including untreated wash water from gas stations and auto repair garages, mobile carpet or steam cleaning wastewater, swimming pool filter backwash, concrete truck washout, and EPA- or state-banned pesticides.

Car washing anywhere other than a commercial carwash is restricted: a resident may wash a vehicle at home only with a hand-held bucket or a hose fitted with an automatic shutoff nozzle, and a business may wash fleet vehicles only at an approved facility, in both cases provided the water does not flow onto the street. Industrial and commercial facilities with more than 25 parking spaces exposed to stormwater must sweep regularly to remove debris. The City Engineer administers the chapter, may issue cease-and-desist orders and notices to clean, and violations are declared a public nuisance that the City can abate and bill to the property owner.
