Full Breakdown

Chapter 22B, the Stormwater Management and Discharge Control Ordinance, implements the federal Clean Water Act and the city's NPDES Permit No. CAS612008 issued under Order R2-2009-0074. 15. 100 separately bans illicit drainage connections, and that ban is written to be retroactive, reaching connections made in the past regardless of whether they were permitted or lawful when installed. 040(F): the City Manager, Public Works Director, Community Development Director, Police Chief, Fire Chief, and their designees. 130. 170(E).

Violations & Fines

Section 22B.170(B) makes a first violation, or a first three violations of the same provision, an infraction punishable under Government Code Chapter 36900; a fourth violation of the same provision within twelve months can be charged as a misdemeanor and referred to the Solano County District Attorney for criminal prosecution. Each day a violation continues counts as a separate offense under Section 22B.170(C), and the City Council sets fine amounts by resolution under Section 22B.170(D), on top of nuisance-abatement costs and liens under Section 22B.200.
