FEMA Flood Zone Lookup

FEMA assigns every parcel in the U.S. a flood-hazard designation on its Flood Insurance Rate Maps (FIRMs). Zones starting with A or V are high-risk Special Flood Hazard Areas where federally backed mortgages require NFIP flood insurance. Zone X indicates moderate-to-minimal risk, where insurance is optional but often recommended. Your specific zone determines insurance cost, build elevation, and permit requirements in Henderson, NV.

AE	High-risk; same as A but with established Base Flood Elevations.	Yes
AH	High-risk shallow flooding (1-3 ft), usually ponding.	Yes
AO	High-risk shallow flooding (1-3 ft) with sheet flow on sloping terrain.	Yes

Summary

Henderson requires new construction and substantial improvements on flood-hazard building sites to be elevated or anchored, built with flood-resistant materials, and reviewed by the Department of Public Works before a permit issues.

The department of public works shall review all building permit applications for new construction or substantial improvements to determine whether proposed building sites will be reasonably safe from flooding. If a proposed building site is in a location that has a flood hazard, any proposed new construction or substantial improvement ... must (i) be designed (or modified) and anchored to prevent flotation, collapse, or lateral movement of the structure; (ii) use construction materials and utility equipment that are resistant to flood damage.

Full Breakdown

Under HMC 13.04.270, public works must review every building permit application for new construction or substantial improvement to confirm the site is reasonably safe from flooding. If the site sits in a mapped flood hazard area, the project must be anchored against flotation and lateral movement and built with flood-resistant materials and methods. Section 13.04.280 applies the same flood-damage-minimization standard to subdivision review, and the city has adopted FEMA flood plain maps for Clark County by reference under HMC 15.50.020.

Violations & Fines

Public works can withhold or condition a building permit until anchoring, flood-resistant construction, and drainage requirements are met; noncompliant construction risks permit denial and possible NFIP flood-insurance rating consequences.
