Full Breakdown
Zoning Ordinance § 24.5.1, inside the Airport Approach and Departure District overlay around Columbia Regional Airport, requires any building sited within the 65 Ldn or higher noise contour to incorporate design and construction measures achieving a 25-decibel interior noise level reduction. The requirement targets noise-sensitive spaces: bedrooms, public-reception areas, offices, and assembly rooms. The contour boundary is fixed by the airport's FAR Part 150 Noise Compatibility Study, adopted by reference into the official zoning map, and the rule applies only within the mapped overlay, not countywide.
Violations & Fines
Building without the required interior noise reduction is a zoning violation under § 18, a misdemeanor, and permit applications inside this overlay are routed to the Columbia Regional Airport manager for a written recommendation under § 24.5.2.
