How Fairfield Handles Environmental Rules: A Practical Guide

Fairfield maintains 148 local ordinances across all categories, and 4 of those deal specifically with environmental rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Fairfield falls on the strict-to-permissive spectrum compared to other cities.

Stormwater Management

Fairfield bans any non-stormwater discharge into its storm drain system under City Code Section 22B.070, and Section 22B.170(B) escalates repeat violations from an infraction to a misdemeanor after a third offense in twelve months, with possible referral to the District Attorney.

Key details: Baseline rule: no non-stormwater discharge to storm drains. Illicit connections: unlawful, retroactive to past hookups. 1st-3rd violation: infraction (Gov. Code Ch. 36900). 4th+ violation in 12 months: chargeable as a misdemeanor. Continuing violation: each day is a separate offense.

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.

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

Flood Elevation Requirements

New construction and any 'substantial improvement' inside Fairfield's mapped flood hazard area must sit at least one foot above the base flood elevation at the lowest floor, including the basement, under Municipal Code § 8A.5.1.3. In Zone AO, the lowest floor must clear the FIRM's depth number by a foot, or three feet above the highest adjacent grade if no depth number is shown. A registered engineer or surveyor must certify the finished elevation.

Key details: Freeboard: 1 foot above base flood elevation. Zone AO rule: 1 ft above FIRM depth number, or 3 ft. Nonresidential option: Floodproof watertight instead of elevating. Certification: Registered engineer or surveyor required. Verification: Building inspector confirms before compliance recorded.

Building below the required elevation, or without the certification the chapter demands, is enforced the same way as any other Chapter 8A violation: Section 8A.3.3 makes noncompliance a misdemeanor, and Section 8A.6.2 separately allows it to be charged as an infraction under Section 1.7, with the City Attorney able to sue to abate a noncompliant structure as a public nuisance at the City Manager's request.

Flood Zones

Anyone building or developing land inside Fairfield's mapped special flood hazard area must get a floodplain development permit from the Director of Public Works before work begins, under Municipal Code § 8A.4.1. The application must show lot elevation, structure and fill locations and drainage, and violating the chapter is treated as a misdemeanor under § 8A.3.3.

Key details: Permit required: Before any construction/development in flood hazard area. Issuing authority: Director of Public Works. Flood maps adopted: FIRM/FBFM dated April 16, 1991. Compliance penalty: Misdemeanor (§8A.3.3) / infraction (§8A.6.2). Appeal path: City Council within 10 days.

Chapter 8A backs the permit requirement two ways: Section 8A.3.3 states that violating the chapter's requirements 'shall constitute a misdemeanor,' while Section 8A.6.2 separately provides that violation 'shall be an infraction punishable as provided in section l.7 of this code.' Either way, any noncompliant use of property is also declared a public nuisance that the City Attorney can sue to abate, remove or enjoin at the City Manager's request.

Compared to other cities, Fairfield takes a harder line on flood zones. The enforcement and penalty structure reflects that.

Erosion Control

Fairfield's Grading and Erosion Control article, City Code Section 25.247, requires every grading project to protect cut and fill slopes from erosion, cap slope steepness at 2:1, and stabilize exposed soil before the October 15-April 15 rainy season. The city engineer enforces the standard through the grading permit process.

Key details: Max slope: 2:1 (horizontal:vertical) unless engineered. Stabilization deadline: Before Oct 15 rainy season start. Enforcing agency: City Engineer. Permit trigger: Grading permit plus performance bond. Guidance manual: ABAG Erosion & Sediment Control Manual.

Grading without the required erosion controls exposes a project to a stop-work order from the city engineer under Section 25.244's permit conditions, and the city may draw on the performance bond required under Section 25.245 to complete or correct unfinished slope protection. Section 25.248 gives the city engineer inspection authority over every active grading site, including special inspection and testing, and can require design or operational changes mid-project if weather-driven erosion problems appear that weren't accounted for when the permit issued.

The Bottom Line

Fairfield is tougher than many cities when it comes to environmental rules. Out of the 4 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Fairfield, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

All of the above reflects Fairfield's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
