Full Breakdown

Stamford's Zoning Regulations require a Flood Hazard Area Permit for all development within a special flood hazard area, satisfied by either a Coastal Site Plan Approval from the Zoning Board (coastal boundary properties) or an Inland Wetland and Watercourses Permit from the Environmental Protection Board (all other properties). Flood zones are mapped from FEMA's Fairfield County Flood Insurance Study and FIRM panels, adopted by reference. The Minimum Elevation Standard is the base flood elevation plus one foot of freeboard: e.g., a 12.00-foot NAVD base flood elevation sets a 13.00-foot minimum. This section is maintained current to May 31, 2026 within the Zoning Regulations (originally adopted 1951).

Violations & Fines

Building below the Minimum Elevation Standard or without a Flood Hazard Area Permit blocks Building Permit and Certificate of Occupancy issuance; the Chief Building Inspector may not issue either until the permit is obtained and compliance documented.
