Summary

Buffalo requires a floodplain development permit for any construction, fill, excavation, or other development in a Special Flood Hazard Area (SFHA), and mandates that new residential structures be elevated at least two feet above the base flood elevation.

§ 31-4.2-1 Purpose A floodplain development permit is hereby established for all construction and other development to be undertaken in areas of special flood hazard in this community for the purpose of protecting its citizens from increased flood hazards and insuring that new development is constructed in a manner that minimizes its exposure to flooding. It shall be unlawful to undertake any development in an area of special flood hazard, as shown on the Flood Insurance Rate Map enumerated in Section 3.2, without a valid floodplain development permit.
§ 31-3.5 Penalties for Non-Compliance No structure in an area of special flood hazard shall hereafter be constructed, located, extended, converted, or altered and no land shall be excavated or filled without full compliance with the terms of this local law and any other applicable regulations. Any person who violates this local law or fails to comply with any of its requirements shall, upon conviction thereof, be fined no more than $250 or imprisoned for not more than 15 days or both. Each day of noncompliance shall be considered a separate offense.
§ 31-5.3-1 Elevation Within Zones A1-A30, AE and AH if base flood elevation data are available, new construction and substantial improvements shall have the top of the lowest floor (including basement) elevated to or above two feet above the base flood elevation.

Full Breakdown

Article 31 of the Buffalo City Charter establishes comprehensive flood damage prevention regulations that apply to all areas designated as special flood hazard areas on FEMA Flood Insurance Rate Maps. A floodplain development permit (fee: $250 application, up to $500 additional review deposit) is required before any development in an SFHA. Residential structures in Zones A1-A30, AE, and AH must have the lowest floor elevated at least 2 feet above the base flood elevation; non-residential structures must either be elevated to the same standard or be floodproofed to that level. The Commissioner of Public Works, Parks and Streets serves as Local Administrator. Variances may be granted by the Flood Hazard Review Board but are subject to strict criteria.

Violations & Fines

Any person who violates this local law shall, upon conviction, be fined no more than $250 or imprisoned for not more than 15 days, or both. Each day of noncompliance is a separate offense. A stop-work order may also be issued. Structures found non-compliant are reported to FEMA, which can affect National Flood Insurance Program rates.

Frequently Asked Questions

Do I need a special permit to build an addition or pour a concrete pad in a flood zone?

Yes. Any development, including additions, fill, excavation, and paving, in a Special Flood Hazard Area requires a floodplain development permit from the Commissioner of Public Works, Parks and Streets before work begins.

How high does my house's lowest floor need to be in a flood zone?

In Zones A1-A30, AE, and AH, the top of the lowest floor (including basement) must be at or above two feet above the mapped base flood elevation.

What happens if I build in a flood zone without a permit?

You can be fined up to $250 per day or imprisoned for up to 15 days per day of noncompliance, and the city may issue a stop-work order and notify FEMA, which can result in higher flood insurance premiums.
