Showing ordinances that apply to Nelson, NV
Nelson is an unincorporated community (population 22) in Clark County, Nevada. Because Nelson is not an incorporated city, it does not have its own municipal code. Instead, Clark County ordinances apply directly to properties here. The flood zones rules below are the ones that govern your area.
Clark County participates in NFIP and enforces Title 28 Flood Damage Prevention in FEMA Special Flood Hazard Areas. The CCRFCD maintains regional flood channels and drainage master plans.
Clark County participates in the National Flood Insurance Program (NFIP) and enforces floodplain development through Clark County Code Title 28 Flood Damage Prevention. In FEMA Special Flood Hazard Areas (SFHA, Zone A and AE), new residential structures must have the lowest floor elevated at least 1 foot above base flood elevation (freeboard), and non-residential structures must be elevated or dry-floodproofed. Substantial improvements (50 percent or more of market value) trigger full compliance. Construction in floodways requires no-rise certification from a Nevada-licensed engineer. The Clark County Regional Flood Control District (CCRFCD) collects a 0.25-cent sales tax that funds regional flood channels, detention basins, and the Duck Creek, Flamingo, Tropicana, and Las Vegas Wash systems. Monsoon flash floods regularly close Strip-area streets; the July 2022 and July 2023 storms caused millions in damage. Elevation certificates are required for NFIP policies in SFHAs. Clark County has earned a CRS (Community Rating System) rating that provides flood insurance premium discounts for residents in participating communities.
Floodplain development without permits or proper elevation can trigger Title 28 enforcement, mandatory removal or elevation, and loss of NFIP coverage. Violations reported to FEMA can jeopardize community NFIP standing.
