Stormwater Management
Las Vegas regulates stormwater discharge under its Municipal Separate Storm Sewer System (MS4) NPDES permit issued by the Nevada Division of Environmental Protection. The Clark County Regional Flood Control District coordinates valley-wide stormwater management. Las Vegas Municipal Code Title 13 addresses storm drainage standards, requiring new developments to incorporate detention basins and post-construction best management practices to prevent pollutants from entering the Las Vegas Wash and Lake Mead.

Las Vegas requires erosion and sediment control plans for construction projects disturbing one acre or more under the NPDES Construction General Permit (CGP). The City's building permit process requires a Stormwater Pollution Prevention Plan (SWPPP) for qualifying sites. Dust control is also strictly enforced by the Clark County Department of Environment and Sustainability under Regulation 41 for PM-10.

Some RestrictionsCoastal Development
Las Vegas is a landlocked desert city with no coastline, so coastal development regulations do not apply. The nearest large water body is Lake Mead, which is managed by the National Park Service as part of the Lake Mead National Recreation Area. Any development near Lake Mead falls under federal jurisdiction rather than city ordinances.

Flash flooding is a significant hazard in Las Vegas due to the desert terrain and monsoon storms. FEMA flood zone maps designate substantial areas of the valley as Zone A and Zone AO. The Clark County Regional Flood Control District manages flood infrastructure, and LVMC Title 16 requires flood-resistant construction in designated flood zones. Properties in Special Flood Hazard Areas must carry flood insurance if they have a federally backed mortgage.

Heavy RestrictionsGrading & Drainage
Any site preparation that moves dirt — clearing, grubbing, cutting, filling, or grading — within the City of Las Vegas requires a grading permit through the Las Vegas Department of Public Works. A drainage study is mandatory if the site is in a FEMA Special Flood Hazard Area, near a Clark County Regional Flood Control District (CCRFCD) Master Plan facility, or impacted by off-site flows. On-site grading permits cover private property; any work in public right-of-way or drainage facilities requires a separate off-site permit and bond.
