Nevada Flood Zone Map
Last updated: August 2026
Nevada faces flash flooding from intense thunderstorms in desert terrain, as well as snowmelt flooding in the Sierra Nevada foothills around Reno. Hard desert surfaces and sparse vegetation create rapid runoff conditions that can turn dry washes into dangerous torrents.
2 of 17 Nevada counties are rated high or very high for inland flood risk by FEMA's National Risk Index. 9 communities participate in FEMA's Community Rating System, qualifying residents for flood insurance discounts of up to 25%.
Nevada has recorded 1,962 NFIP flood insurance claims since 1978, totaling $47.4M in payouts. See how Nevada compares in our nationwide NFIP claims data breakdown.

Levee Protection in Nevada
The USACE National Levee Database lists 8 levee systems protecting parts of 5 Nevada cities. A system's FEMA accreditation status determines how its protected area is mapped - accredited levees are typically mapped as Zone X, while non-accredited or provisionally accredited (PAL) systems generally leave their protected area in the SFHA.

Nevada Flood Zone FAQ
How do I check if my Nevada property is in a flood zone?
Enter your NV address in FludZone's free lookup tool. We query FEMA's National Flood Hazard Layer in real-time to show your flood zone designation, whether flood insurance is required, and your property's risk level.
Do I need flood insurance in Nevada?
If your Nevada property is in a Special Flood Hazard Area (SFHA), meaning zones starting with A or V, and you have a federally regulated or government-backed mortgage, federal law generally requires your lender to ensure you carry flood insurance. Properties in Zone X are not subject to the federal mandate but lenders may still require coverage, and it is often recommended given Nevada's flood history.
What are the most common flood zones in Nevada?
The most common FEMA flood zone designations in Nevada are Zone AE, Zone AO, Zone A, Zone X. Each zone reflects a different level of flood risk, from high-risk areas where flood insurance is generally required for federally regulated or government-backed mortgages to lower-risk areas where coverage is optional but recommended.
Can I remove my Nevada property from a flood zone?
Yes, if your Nevada property's natural ground elevation was always above the Base Flood Elevation and FEMA inadvertently mapped it in the SFHA, you can apply for a Letter of Map Amendment (LOMA) through FEMA. For properties in Nevada's AE and A zones, the LOMA process is relatively straightforward when the elevation data supports it. If your property was raised above the BFE with fill, the process is a LOMR-F. A successful LOMA generally removes the federal mandatory flood insurance requirement, but your lender may still choose to require coverage. You'll need an elevation certificate from a licensed surveyor.
Do any Nevada communities offer flood insurance discounts?
Yes, 9 Nevada communities participate in FEMA's Community Rating System (CRS), a voluntary program that rewards communities for exceeding minimum flood mitigation standards. Residents in participating communities can receive NFIP premium discounts of up to 25% in the Special Flood Hazard Area. Properties outside the SFHA also benefit: CRS classes 1 through 6 receive a 10% discount, and classes 7 through 9 receive a 5% discount on NFIP premiums. Check your city's page on FludZone to see if your community participates.
How much does flood insurance cost in Nevada?
The average NFIP flood insurance premium in Nevada is $899 per year across 10,392 active policies. Premiums vary by zone: Zone AO policies average $770/yr. Under FEMA's Risk Rating 2.0, your specific premium depends on property type, elevation relative to the Base Flood Elevation, and distance to water, not just your flood zone designation.
Which Nevada counties have the highest flood risk?
According to FEMA's National Risk Index, Clark, Washoe are among Nevada's highest-risk counties for inland flooding. Overall, 2 of 17 Nevada counties are rated "High" or "Very High" for inland flood risk. County-level ratings account for historical flood losses, social vulnerability, and community resilience.

Nevada has recorded 1,962 NFIP flood insurance claims totaling $47.4M in payouts since 1978. The highest-claim year was 1997, with 470 claims and $19.8M in payouts. This history reflects cumulative flood damage to Nevada properties across decades of storm and rainfall events.
How many Nevada properties have flooded repeatedly?
Nevada has 104 properties with multiple flood losses. Of these, 7 are classified as Severe Repetitive Loss, meaning they have experienced four or more NFIP claims of $5,000 or more, or two or more claims where the total exceeds the building value. 3 of these properties have been mitigated.
What percentage of Nevada homes have flood insurance?
Only roughly 1 in 118 households in Nevada carries NFIP flood insurance (0.8% of estimated households). 11 counties in Nevada have elevated flood risk but low insurance coverage, indicating a significant protection gap.
Are there levees protecting Nevada cities?
