Summary

Nevada participates in the National Flood Insurance Program through the Division of Water Resources under NRS Chapter 540, requiring participating local governments to adopt floodplain management ordinances meeting FEMA minimum standards as a condition of flood insurance availability.

NRS 543.595 Adoption of uniform regulations; variances; incorporation of regulations into ordinances by city or county; compliance with standards, criteria and policies of board. 1. The board shall adopt uniform regulations for the control of drainage, in accordance with the master plan, from land which is developed after the regulations become effective. The regulations may include provisions for the granting of a variance by the board upon application by the governmental entity having jurisdiction and a showing of conditions which justify the variance. The board may grant a variance from the strict enforcement of the uniform regulations for that piece of property if the granting of the variance will not cause any: (a) Detriment to the public good; (b) Impairment of any affected natural resources; or (c) Deviation from the intent and purpose of the district's master plan. 2. Before granting such a variance, the board must consider the effect of the proposed variance on the adjacent property, the entire hydrographic area and the continued implementation of the master plan.

Full Breakdown

Under NRS Chapter 540 and 44 CFR Part 60, the Nevada Division of Water Resources coordinates floodplain management statewide. Communities participating in the NFIP must adopt and enforce ordinances that regulate development in mapped Special Flood Hazard Areas, require elevation of new structures above base flood elevation, restrict fill in floodways, and require floodplain development permits. Cities and counties may adopt stricter standards but cannot fall below FEMA minimums without losing NFIP eligibility for residents. Substantial improvements to existing buildings exceeding 50 percent of value trigger full compliance with current standards.

Violations & Penalties

Building in a regulated floodway without a permit may trigger removal orders, daily fines under local code, suspension from the NFIP, and denial of federal disaster assistance.

Frequently Asked Questions

Can my city allow building in a floodway?
No. To remain in the NFIP, communities must prohibit development in regulatory floodways unless an engineering analysis shows no rise in base flood elevation.
Do I need flood insurance in Nevada?
Federally backed mortgages on properties in Special Flood Hazard Areas require flood insurance. Owners outside high-risk zones may purchase preferred-risk policies voluntarily.
