Summary

Vallejo bans discharging anything but stormwater into its storm drain system under Section 12.41.060, and requires a city-approved Stormwater Control Plan before many development projects can get a certificate of occupancy. The Director of Public Works enforces the chapter, which implements the city's NPDES Permit No. CAS612008; violations are misdemeanors, or at the city's discretion infractions, carrying fines up to state statutory limits.

Full Breakdown

41, adopted by Ordinance No. ), the federal Clean Water Act, and the conditions of the city's NPDES Permit No. CAS612008. 060 prohibits releasing any non-stormwater discharge, defined as any pollutant added to the stormwater system other than rain runoff, and separately bans any stormwater discharge that would violate the receiving-water limits in the city's NPDES permit. Narrow exemptions cover NPDES-compliant discharges, natural flows such as riparian habitat water and rising groundwater, and conditional exemptions such as air-conditioning condensate, individual residential car washing, and irrigation runoff.

3 Guidebook and the city's addendum to it; implementing that plan, plus recording a maintenance covenant granting the city, the Vallejo Sanitation and Flood Control District, the Solano County Mosquito Abatement District, and the regional water board inspection access, is a condition of getting a certificate of occupancy. 090 layers on specific best-management-practice duties: no litter in streets, creeks, or the storm system; sidewalks must be kept free of dirt swept into the gutter; construction sites must run erosion, sediment, and run-on/run-off controls; and businesses handling hazardous materials must fold stormwater compliance into their Hazardous Material Release Response and Inventory Plan under Health and Safety Code section 25500.

Violations & Fines

Section 12.41.120 makes any violation a misdemeanor, though the enforcement officer or city attorney can instead charge it as an infraction. Section 12.41.130 caps the resulting fine or imprisonment at the limits set in Government Code sections 36900 and 36901, and every day a violation continues is a separate offense under Section 12.41.140. The city can also abate an unresolved violation itself and bill the property owner for the abatement costs, plus attorney fees, and record an unpaid bill as a lien against the property under Section 12.41.170.

Frequently Asked Questions

What can't I put down a Vallejo storm drain?
Anything other than stormwater. Section 12.41.060 bans all non-stormwater discharges, with narrow exemptions for things like natural spring flows, air-conditioning condensate, and individual residential car washing; even irrigation runoff is only conditionally exempt.
Do I need a stormwater plan to build in Vallejo?
If your project needs a rezoning, tentative map, conditional use permit, variance, site development permit, or a building permit that triggers the city's development runoff requirements, yes. Section 12.41.050 requires an approved Stormwater Control Plan before the city will issue a certificate of occupancy.
What is the penalty for a stormwater violation?
Misdemeanor penalties under Government Code sections 36900 and 36901, though the city can instead charge it as an infraction. Every day the violation continues counts as a separate offense, and the city can abate it and bill the owner, recording unpaid costs as a property lien.
Who inspects for stormwater compliance in Vallejo?
The Director of Public Works and designated enforcement officers, who can inspect sites, set sampling devices, and require monitoring and reporting under Section 12.41.100, sometimes jointly with the Vallejo Sanitation and Flood Control District or the Regional Water Quality Control Board.
