Environmental Rules in Roseville, CA

If you live in Roseville or are thinking about moving there, environmental rules are one of those things you probably won't think about until they affect you directly. Roseville has 4 specific rules on the books covering different aspects of environmental rules, and some of them might surprise you.

Flood Zones

Any construction or development within a mapped area of special flood hazard in Roseville requires a floodplain development permit issued in advance by the floodplain administrator, the city's community development director, under Municipal Code Chapter 9.80. The rule applies citywide wherever FEMA's Flood Insurance Rate Map, adopted September 28, 1989, designates special flood hazard or flood-related erosion areas.

Key details: Permit required: Before any construction in a mapped flood hazard area. Administrator: Community Development Director. Governing map: FIRM dated September 28, 1989. Map on file at: City Engineer, 316 Vernon Street. Violation penalty: Infraction or misdemeanor, city attorney's discretion.

Constructing, extending, converting or altering a structure in a mapped flood hazard area without a development permit, or violating any permit condition, is a public nuisance under §9.80.070. The city attorney may charge it as an infraction or a misdemeanor, and the city can pursue any other lawful remedy to stop the work or require correction, independent of the criminal or infraction case.

Flood Elevation Requirements

Roseville requires two feet of freeboard: new or substantially improved residential buildings must have their lowest floor, including any basement, elevated at least two feet above the base flood elevation under Municipal Code §9.80.160(C)(1). All flood-vulnerable equipment, from HVAC to electrical panels, must sit above that line, and the floodplain administrator supplies the base flood elevation figure for the parcel.

Key details: Freeboard required: 2 feet above base flood elevation. Applies to: New residential construction and substantial improvements. Certification by: Registered engineer or licensed land surveyor. Below-BFE use limit: Parking, access or storage only (deed restriction). Enclosure venting: 1 sq in per sq ft, min 2 openings.

Occupying or certifying a structure that was not elevated at least two feet above the base flood elevation, or skipping the required engineer's or surveyor's elevation certification, keeps the project out of compliance with Chapter 9.80 and exposes the owner to the same public-nuisance enforcement as any noncompliant flood-hazard-area development: an infraction or misdemeanor charge at the city attorney's discretion under §9.80.070.

Stormwater Management

Roseville makes it unlawful to discharge sewage, industrial waste, pollutants, garbage or rubbish into any municipal storm drain, watercourse, natural outlet, creek or channel except under a listed exemption or a state/federal NPDES permit. City Code Section 14.20.120 backs the city's own NPDES permit, Order No. 2013-0001-DWQ, Permit No. CAS000004, and is enforced by the environmental utilities director and city engineer.

Key details: Prohibited: Non-permitted discharges to storm drains/watercourses. Permit basis: City NPDES Permit No. CAS000004. Enforcing agency: Environmental Utilities Director / City Engineer. Spill cleanup deadline: 72 hours from notification. Appeal window: 10 days to appeal a citation or order.

Section 14.20.410 makes it unlawful to violate any provision of the chapter, chargeable as an infraction or misdemeanor at the city attorney's discretion, with each day of a continuing violation a separate offense under Section 14.20.520. Section 14.20.430 lets the director or city engineer order a discharger to abate and clean up a spill within 72 hours of notification, or abate an uncontrolled pollutant source within 30 days, and Section 14.20.460 lets the city treat an uncorrected violation as a public nuisance and abate it at the property owner's expense, with a lien if the invoice goes unpaid 60 days. A recipient of a cease-and-desist order or citation may appeal to the board of appeals within 10 days under Section 14.20.450.

This is not one of those rules that cities tend to ignore. Roseville actively enforces its stormwater management requirements.

Erosion Control

Roseville requires any construction project subject to a State Water Resources Control Board stormwater pollution prevention plan (SWPPP) to follow that plan at all times, and the city can order the crew to correct any failure or stop work outright. City Code Section 14.20.290(C) folds the state SWPPP obligation into the city's own stormwater enforcement chapter.

Key details: SWPPP trigger: Construction disturbing 1 acre or more. Governing section: RMC Sec. 14.20.290(C). Enforcement tool: Stop work order, Sec. 14.20.480. City guidance doc: Construction Activities BMP Guidance Manual. Penalty type: Infraction or misdemeanor, city attorney's choice.

Section 14.20.480 lets the city engineer or an enforcement officer stop work by written notice to anyone doing work contrary to the chapter, and that work must halt until the city engineer authorizes it to resume. Failing to adhere to a reviewed SWPPP or to correct a deficiency exposes the responsible party to Section 14.20.410's general violation provisions, chargeable as an infraction or misdemeanor at the city attorney's discretion, and to a cease-and-desist order under Section 14.20.430 requiring cleanup within 72 hours of notification.

This is one of the stricter rules in Roseville's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
