Summary
Ridgefield requires new and substantially improved residential structures in a mapped flood hazard area to have the bottom of the lowest floor, including any basement, built at or above the base flood elevation, with all servicing electrical, plumbing and mechanical equipment elevated to the same level.
Residential Construction. All new construction, substantial improvements, and repair to structures that have sustained substantial damage which are residential structures shall have the bottom of the lowest floor, including basement, elevated to or above the base flood elevation (BFE). Electrical, plumbing, machinery or other equipment that service the structure must be elevated to the same level or above the BFE.

Full Breakdown
1 of the Zoning Regulations, the Town's floodplain management standards administered by the Planning and Zoning Commission, sets the residential construction rule for the Special Flood Hazard Area: the lowest floor of any new construction, substantial improvement, or repair of substantial damage, including the basement, must be elevated to or above the base flood elevation (BFE), and all electrical, plumbing, machinery or other equipment servicing the structure must be elevated to that same level or higher. 2: instead of elevating, they may be dry flood-proofed to one foot above the BFE if a Connecticut-registered engineer or architect certifies the design on FEMA Flood-proofing Certificate Form 81-65.
1 requires the Commission to use the best available federal, state or other data, and if no BFE can be determined at all, the lowest floor must still be elevated to two feet above the highest adjacent grade next to the structure. Ridgefield's separate Town Code Chapter 188, Flood Damage Prevention, layers on general requirements that new construction in a special flood hazard area be anchored against flotation and built with flood-resistant materials, and requires a development permit from the Commission before work begins.
Violations & Fines
Building below the required base flood elevation without the Commission's floodplain development permit is enforced the same as any zoning violation: the Zoning Enforcement Officer issues a Section 9.4 notice ordering correction within ten days, and the property owner is subject to the fines, injunctive remedies and per-day penalties available under Connecticut General Statutes Chapter 124, in addition to the flood-insurance consequences of noncompliant construction.
