Summary

San Rafael bans any non-stormwater discharge into its storm drain system under the Urban Runoff Pollution Prevention Ordinance, Chapter 9.30. Violations are a public nuisance and a misdemeanor or infraction, enforceable by administrative citation, civil action, or summary abatement with a lien on the property.

The discharge of non-stormwater discharges to the city's storm drain system is prohibited. All discharges of material other than stormwater must be in compliance with an (NPDES) permit issued for the discharge.

Full Breakdown

060 flatly prohibits discharging anything other than stormwater to the city's storm drain system, and requires any non-stormwater discharge to be covered by its own NPDES permit. 070 exempts specific low-risk discharges, such as fire-fighting flows, individual residential car washing, foundation and footing drains, air conditioning condensation, dechlorinated pool water, and incidental irrigation runoff, provided property owners implement listed best management practices, including repairing irrigation leaks within 72 hours and properly aiming sprinkler heads. 090 separately bans illicit connections to city storm drains or watercourses and applies retroactively to connections made in the past regardless of whether they were once permitted.

130 specifically requires parking lots and similar paved areas to be cleaned as frequently as practicable so they don't discharge pollutants. 110 bars littering that could become a pollutant discharge into any street, storm drain, catch basin, or drainage structure. 030 to include the city manager, director of public works, fire chief, stormwater program manager, code enforcement officer, and health officer, implementing the Phase II Stormwater Permit issued under the federal Clean Water Act and California's Porter-Cologne Water Quality Control Act.

Violations & Fines

Under § 9.30.200, any condition violating Chapter 9.30 is deemed a public nuisance that the city may summarily abate, restore, or enjoin, and § 9.30.210 makes abatement and restoration costs a lien against the property. Section 9.30.250 makes violating any mandatory requirement of the chapter a misdemeanor, though the enforcement authority may instead charge it as an infraction, with fines and imprisonment capped at the limits set in Government Code §§ 36900-36901; each day a violation continues is a separate offense. The city attorney may also bring a civil action under § 9.30.260 seeking injunctions, investigation and cleanup costs, compensatory damages for harm to water quality or wildlife, and treble damages under §§ 1.42.020-1.42.040, and an authorized enforcement official may issue cease-and-desist orders under § 9.30.270 ranging from verbal warnings to formal administrative enforcement.

Frequently Asked Questions

Can I wash my car in my San Rafael driveway?
Yes. Section 9.30.070(C)(2) exempts individual residential car washing from the discharge prohibition, along with other listed low-risk flows like foundation drains and air conditioning condensation, as long as pollutants are minimized.
What counts as an illegal discharge to the storm drain in San Rafael?
Section 9.30.060 prohibits any discharge to the city's storm drain system that is not stormwater and not covered by its own NPDES permit. Section 9.30.090 also separately bans illicit connections, applying even to connections made years ago.
Who enforces San Rafael's stormwater ordinance?
Section 9.30.030 defines the 'authorized enforcement official' as the city manager, director of public works, fire chief, stormwater program manager, code enforcement officer, or health officer, any of whom may act under Chapter 9.30.
What happens if my sprinklers overwater onto the street in San Rafael?
Excess irrigation runoff is only exempt from the discharge ban if you control it under § 9.30.070(D), including repairing leaks within 72 hours and properly aiming sprinkler heads; uncontrolled overspray beyond that is a chargeable violation under § 9.30.250.
Can the city put a lien on my property over a stormwater violation?
Yes. Section 9.30.210 makes abatement and restoration costs for a stormwater public nuisance a lien upon the property, collected under state law and the city code until paid.
