Beaumont, CA Environmental Rules: Stormwater Management (2026)

Section 13.24.050 is the core rule in the City of Beaumont, California. It is a violation to throw, deposit, leave or keep any pollutant on any street, alley, sidewalk, storm drain, inlet, catch basin, conduit or drainage structure, or on any public or private land in the city. The only exception is a pollutant temporarily placed in an appropriate container with a spill containment system for later removal. A dumpster or solid waste bin that leaks a pollutant is also a violation. Anyone doing construction work must follow the chapter and other city ordinances on erosion and sediment control.

New development and redevelopment projects must control runoff so water quality does not deteriorate, and the City Engineer identifies the BMPs that apply. The listed options include more permeable area, directing runoff to swales, berms, rain gardens or pervious pavement, and storage in cisterns or retention structures for reuse. Existing development is under the same duty. Section 13.24.060 bans illicit connections and discharges to the storm drain system and applies retroactively to past connections. Section 13.24.070 treats non-stormwater as a violation except for discharges under a state NPDES permit or waiver and a listed set of managed discharges, including landscape irrigation, water line flushing, individual residential car washing, air conditioning condensate and swimming pool discharges.

Under § 13.24.080, industrial and construction dischargers must comply with the industrial stormwater general permit and the dewatering general permit, and the City Engineer can require proof of compliance before issuing any city grading, building or occupancy permit. Compliance is a condition of every city permit, license or approval (§ 13.24.090). The City Engineer can inspect premises at reasonable times, with an inspection warrant if entry is refused (§ 13.24.100), and the City Council can set an inspection fee by resolution (§ 13.24.110). The chapter tracks the Federal Clean Water Act, the Porter-Cologne Water Quality Control Act and the municipal NPDES permit.
