Summary
Edmond requires two feet of freeboard: new construction and substantial improvements in a flood hazard area must have their lowest floor at least 2 feet above base flood elevation, certified by a licensed engineer or surveyor.
The lowest floor (including entry floor level, living areas, garage, basement, walk-out, electrical and mechanical equipment, and ductwork) must be elevated a minimum of two (2) feet above the base flood elevation. A registered professional engineer, architect, or land surveyor shall submit a completed Federal Emergency Management Agency Elevation Certificate to the Floodplain Administrator showing that the standard of this subsection is satisfied.

Full Breakdown
The 2-foot freeboard standard applies to new construction, substantial improvements, and manufactured homes, and is separately restated for residential and nonresidential structures on lots abutting a regulated floodplain. "Lowest floor" includes the garage, basement, walk-out level, and mechanical/ductwork, not just living space. Compliance is documented on a FEMA Elevation Certificate signed by a registered engineer, architect, or land surveyor and filed with the Floodplain Administrator. Manufactured homes must also be anchored against flotation and lateral movement. Residential structures are barred entirely from the Regulatory Floodplain itself, freeboard notwithstanding.
Violations & Fines
Building below the required elevation, or without a filed FEMA Elevation Certificate, is a code violation subject to the maximum fine State Statutes allow per offense, with each day of noncompliance counted separately under § 23.40.100.
