Summary
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.
A flood plain development permit shall be obtained before construction or development begins within any area of special flood hazard established in section 8A.3.2. Application for a flood plain development permit shall be made on forms, furnished by the director of public works, and may include, but not be limited to; plans in duplicate scale showing the nature, location, dimensions, and elevation of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing.

Full Breakdown
2. 1 requires a floodplain development permit before any construction or development begins in that mapped area. 3(c); and a description of any watercourse alteration or relocation. 3 backs the permit requirement with a blunt compliance rule: no structure or land may be constructed, located, extended, converted or altered without full compliance with the chapter, and violating it is a misdemeanor. The Director of Public Works administers the permit and can also grant a narrow variance under Article VII, but only where a parcel's unique physical characteristics create a hardship, never within a mapped regulatory floodway if it would raise flood levels, and only to the minimum elevation relief needed.
Violations & Fines
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.
