FEMA assigns every parcel in the U.S. a flood-hazard designation on its Flood Insurance Rate Maps (FIRMs). Zones starting with A or V are high-risk Special Flood Hazard Areas where federally backed mortgages require NFIP flood insurance. Zone X indicates moderate-to-minimal risk, where insurance is optional but often recommended. Your specific zone determines insurance cost, build elevation, and permit requirements in Framingham, MA.

Full Breakdown

Framingham City Code § 435-17 establishes the Floodplain District as an overlay covering all special flood hazard areas mapped as Zone A and AE on the Middlesex County FIRM, listing 14 specific panel numbers dated July 7, 2014, with the boundaries further defined by the July 7, 2014 Middlesex County Flood Insurance Study. The FIRM and FIS are incorporated by reference and kept on file with the City Clerk, the Department of Public Works, Inspectional Services, the Division of Planning and Community Development, and the Conservation Commission.

All proposed development in the district requires a permit from the Building Commissioner. Any construction, enlargement, extension, or substantial improvement of a building for human habitation, even if normally allowed by right, additionally requires a special permit from the Zoning Board of Appeals (ZBA). In the regulatory floodway, any development or fill that would raise flood levels during the base flood is flatly prohibited; in unnumbered A Zones along watercourses without a designated floodway, the best available federal, state, or local floodway data governs the same prohibition.

Subdivisions or other developments greater than 50 lots or five acres (whichever is less) in unnumbered A Zones must supply base flood elevation data and be designed to minimize flood damage, protect utilities, and provide adequate drainage. Applicants must route plans through the Building Commissioner first, then submit seven copies to the ZBA for a special permit, which are circulated to the City Clerk, Conservation Commission, Board of Health, DPW, Planning Division, and Planning Board for 30-day comment; silence counts as concurrence. No development may encroach on the regulatory floodway, per § 435-17D(9).

Violations & Fines

Building without the required Building Commissioner permit or ZBA special permit in the Floodplain District blocks issuance of a certificate of occupancy under § 435-17E, and no building newly constructed or substantially improved in the district may be occupied until it complies fully with the ZBA-approved site plan and any imposed conditions. The ZBA can also condition or deny a special permit outright where the nine approval criteria in § 435-17D, including anchoring, flood-resistant construction, and floodway non-encroachment, are not met.

Frequently Asked Questions
