Full Breakdown

C of Charlotte's Unified Development Ordinance requires a floodplain development permit, issued in conformance with Article 27, before the commencement of any development activity in a special flood hazard area; the City's Floodplain Regulations Technical Guidance Document helps applicants determine which permit type applies. D bars altering land or locating, extending, constructing, converting, or structurally altering any structure without full compliance with the article. B: every stream in Mecklenburg County draining one square mile or more has an established community and FEMA base flood elevation, community encroachment area, and FEMA floodway, mapped in the effective Flood Insurance Study for Mecklenburg County and the City of Charlotte dated November 16, 2018, and its accompanying Flood Insurance Rate Map, along with any later local or FEMA-approved revisions.

Where a preliminary FIRM and FIS exist and show a higher base flood elevation than the effective maps, the preliminary figures govern for local regulatory purposes. The article applies citywide and within Charlotte's extraterritorial jurisdiction. It reenacts, without a gap in enforcement, the City's prior floodplain regulations effective July 1, 2021, and traces back to Charlotte's original Flood Damage Prevention Ordinance of November 27, 1972 (Mecklenburg County's dates to December 4, 1972).

Violations & Fines

Developing without the required floodplain development permit, or altering land in violation of Section 27.2.D, is enforced as a code violation subject to inspections and enforcement action under UDO Section 27.6.B, which incorporates Article 39's enforcement procedures; appeals and variance requests go through Article 37. The Stormwater Administrator, designated as Floodplain Administrator under Section 27.7.A, administers and enforces the permit requirement, including for areas covered by an interlocal agreement with Mecklenburg County.

What maps define Charlotte's flood zones?

Charlotte and Mecklenburg County use the effective Flood Insurance Study and Flood Insurance Rate Map dated November 16, 2018, plus any later FEMA-approved or local revisions, under UDO Section 27.2.B. Streams draining at least one square mile have mapped base flood elevations.
