West Hartford, CT Environmental Rules: Flood Elevation Requirements (2026)

Section 177-8 defines the base flood elevation (BFE) as the height in relation to mean sea level expected to be reached by the base, or one-hundred-year, flood at a given point, drawing from FEMA's Flood Insurance Study and Flood Insurance Rate Map. The specific construction standard then goes beyond that baseline: in SFHA Zones A and AE, all new construction and substantial improvements of residential and nonresidential structures must have the bottom of the lowest floor, including any basement, elevated 2.0 feet above the BFE, referencing 44 CFR 60.3(c)(2) and (3).

The same 2.0-foot freeboard applies to every piece of utility equipment servicing the structure, including furnaces, oil or propane tanks, air conditioners, heat pumps, hot water heaters, ventilation duct work, washer and dryer hookups, electrical junction boxes and circuit breaker boxes, so mechanical rooms cannot sit at grade even if the living space is elevated. Manufactured homes placed or substantially improved in an SFHA must likewise have the bottom of the frame of the lowest floor 2.0 feet above the BFE on a securely anchored permanent foundation.

Where no BFE has been established for a watercourse, the Director of Community Development must obtain data from federal, state or other sources, and absent any BFE the lowest floor must still be elevated two feet above the highest adjacent grade next to the structure. These freeboard standards were amended April 11, 2023, and are enforced through the same $100-per-day penalty and development-application review described in § 177-8's general floodplain provisions.
