Stormwater Management
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.
