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

Chapter 34, Article III of the Burke County Code sets flood hazard reduction standards for the unincorporated county wherever FEMA has mapped base flood elevation (BFE) data. Under § 34-72(1), new residential construction and substantial improvements must have the lowest floor, including any basement, elevated no lower than the BFE; if solid perimeter foundation walls are used instead of piers, the walls must include openings that let floodwaters move through unimpeded. Nonresidential structures under § 34-72(2) may either meet the same elevation or be floodproofed watertight below the BFE, but only with certification from a registered professional engineer or architect filed with the county.

Manufactured homes placed or substantially improved anywhere in the floodplain, whether inside or outside an existing manufactured home park, must sit on a permanent foundation with the lowest floor at least two feet above the BFE and be anchored under the state's mobile-home anchoring rules; chassis elevations above 36 inches require an engineer's certification. Recreational vehicles are exempt only if they stay fewer than 180 consecutive days, remain licensed and highway-ready, or otherwise meet the elevation standards. Accessory structures valued at $3,000 or less may skip elevation if they are firmly anchored, designed for low flood-damage potential, and not used for human habitation.

Within designated floodways, § 34-72(8) bars any new fill, construction or substantial improvement unless engineering analysis proves it will not raise flood levels. Property owners denied a permit may seek a variance from the board of commissioners under § 34-49, but the board must find the variance is the minimum necessary and give written notice of the resulting flood-insurance risk. A local administrator in Community Development reviews applications, and an owner who ignores a corrective order after a hearing is guilty of a misdemeanor under § 34-48.
