Stormwater Management: Hesperia vs San Bernardino

Do I need a SWPPP for a single-family home?

Most single-family residential lots are under one acre and do not require a statewide Construction General Permit SWPPP, but the city's SWMP requires Erosion and Sediment Control Plans (ESCPs) and a stabilized construction entrance for residential builds. Larger residential subdivisions (≥1 acre of disturbed soil) require a SWPPP through the State Water Board's SMARTS system.

Who regulates stormwater in Hesperia?

Locally, the Hesperia Engineering Department administers the SWMP. Regionally, the Lahontan Regional Water Quality Control Board oversees compliance with the statewide Phase II MS4 General Permit (Order WQ 2013-0001-DWQ as amended).

Can I wash my car in my San Bernardino driveway?

Residential car washing is generally exempt if runoff does not carry soap or sediment to the storm drain. Use biodegradable cleaners, wash on grass or gravel where water absorbs into the soil, or take the vehicle to a commercial car wash that captures wastewater.

How do I drain my swimming pool without violating stormwater rules?

Dechlorinate pool water for at least 48 hours before discharging, confirm no visible color or odor, and drain slowly to your sewer cleanout where allowed or to landscaped areas that absorb water. Never drain directly to a street or storm drain.
