Henderson FAQ
Is my Henderson property in a flood zone?
Check FEMA's Flood Map Service Center or contact Henderson's Community Development Department. Properties near the Las Vegas Wash, Duck Creek, and desert washes are most likely in flood hazard areas.
Can I build in a Henderson flood zone?
Yes, with restrictions. Structures must be elevated above the Base Flood Elevation and meet floodplain management standards. A floodplain development permit is required.
Las Vegas FAQ
Is Las Vegas really at risk for flooding?
Yes. Despite being in the desert, Las Vegas experiences dangerous flash flooding during monsoon season (July through September). Hard desert surfaces provide little absorption, sending water rapidly through washes and streets.
Do I need flood insurance in Las Vegas?
If your property is in a FEMA-designated Special Flood Hazard Area and you have a federally backed mortgage, flood insurance is mandatory. Even outside these zones, flood insurance is recommended given the flash flood risk.
