Full Breakdown

Appendix D, the Flood Damage Prevention ordinance adopted August 12, 2008, applies to every Special Flood Hazard Area (SFHA) shown on the FEMA Flood Insurance Rate Maps for Bristol, including the May 16, 2017 panel and the September 26, 2008 panels covering the rest of the city (§ 3.2). Section 3.3 requires a floodplain development permit before any development activity in those zones. The city engineer, designated as the ordinance administrator under § 4.1 and subject to review by the Flood and Erosion Commission, processes applications, which must show the proposed lowest-floor elevation, describe encroachment into the flood-fringe, and state whether the project meets the substantial-improvement definition (§ 4.2).

Application fees run $5.00 for a permitted use, $50.00 for a regulated use, and $100.00 for a special exception (§ 4.7.1). Permit decisions are published in a newspaper of general circulation, and a permit takes effect seven days after that publication if no appeal is filed (§ 4.2.1(l)). New development or substantial improvement inside the regulated floodway can be allowed only as a special exception granted by the Bristol Flood and Erosion Commission, and only when the applicant's registered engineer certifies no increase in flood levels will result, with expansions capped at 25 percent of the existing building's footprint (§ 4.6). Appeals from the administrator's interpretation or a permit denial go to the Flood and Erosion Commission under the ordinance's variance procedures (§ 7).

Violations & Fines

Section 7.6 makes any violation of the flood damage prevention ordinance, including violation of a variance or special-exception condition, a misdemeanor. A willful violation carries a fine of up to $250.00 per day; an unintentional one, up to $100.00 per day, or imprisonment for up to ten days, or both, plus all of the city's costs and reasonable legal fees for the case.

Frequently Asked Questions

Do I need a permit to build in a Bristol flood zone?

Yes. Appendix D § 3.3 requires a floodplain development permit from the city engineer before any development activity begins in an area of special flood hazard, and the application must show the proposed structure's elevation and how it will affect the flood-fringe area.

How much does a Bristol floodplain permit cost?

Section 4.7.1 sets a $5.00 fee for a permitted use, $50.00 for a regulated use such as new construction in the flood fringe, and $100.00 for a special exception allowing development in the regulated floodway itself.

What happens if I develop without a floodplain permit?

Section 7.6 treats the violation as a misdemeanor: up to $250.00 per day if the violation was willful, up to $100.00 per day if not, up to ten days in jail, or both, plus the city's costs and legal fees in pursuing the case.

Can Bristol allow building inside the floodway itself?

Only as a special exception granted by the Flood and Erosion Commission under § 4.6, and only when a registered engineer certifies the project will not increase flood levels and any expansion stays within 25 percent of the existing building's footprint.
