Rutherford County, NC Environmental Rules: Flood Elevation Requirements (2026)

Chapter 7, Flood Damage Prevention, applies countywide, including the unincorporated area mapped on the July 2, 2008 flood insurance study. Section 7-8 requires a floodplain development permit before any development activity in a special flood hazard area, and section 7-22 lists the application: a scaled plot plan, the SFHA and floodway boundaries, proposed elevations, and, for new residential construction, the reference level elevated no lower than the regulatory flood protection elevation defined in section 7-5. Non-residential structures may instead be floodproofed to that same elevation under section 7-32(2), certified by a professional engineer or architect.

Before construction starts, the permit holder must submit a FEMA Form 81-31 elevation certificate to the floodplain administrator under section 7-22(c), and a final as-built certificate is required before a certificate of compliance or occupancy is issued. Manufactured homes must have their chassis reference level meet the same regulatory flood protection elevation, and an engineered foundation certification is required once the chassis rises above 36 inches. Anyone seeking relief from these standards must apply to the board of appeals for a variance under section 7-25, which weighs flood danger, alternative sites, and the county's comprehensive plan before granting one.
