Weighing a property around Henderson? The North Las Vegas flood zone map tells you whether it sits in a FEMA flood zone, and the lookup is free. What this North Las Vegas guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the County Parcels in Nevada layer in ArcGIS Map Viewer.
Getting started with the North Las Vegas flood zone map
Flood zones come from FEMA's Flood Map Service Center: search an address around Boulder City, then open the map view for that panel. Rural land near Las Vegas with no street number is still easy to locate: pan from the closest town and click inside the land.
The viewer Clark County publishes
Go first to the County Parcels in Nevada layer in ArcGIS Map Viewer; it maps each tax parcel around Mesquite and Las Vegas. Around Boulder City, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. Around Boulder City, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Where North Las Vegas fits in
North Las Vegas lies within Clark County, Nevada, and the county assessor maps its lots. For acreage around Mesquite, City or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Lots just outside the city limits toward Boulder City generally follows county rules instead.
On site with the map
Most viewers work in a phone browser, handy when you're parked on a road near Las Vegas, so load it before you lose signal. A screenshot of the parcel near Mesquite with its ID helps when you meet an owner or agent.
Clark County in a few facts
Las Vegas holds the county offices, home to the main records offices. Other places on the map include Henderson, Boulder City, and Mesquite, each with its own cluster of lots. Roughly 2,336,573 people live in Clark County (Census Bureau estimate, 2023) across roughly 7,892 square miles. Places such as Colorado River, Lake Mead, and Avi Kwa Ame National Monument are easy to spot when you zoom out from Mesquite.
Beyond the mapped zones
Small streams around Boulder City aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Las Vegas can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
When a parcel crosses a boundary
Clark County touches Mohave County, AZ, Inyo County, CA, San Bernardino County, CA, Lincoln County, and Nye County, and each of those keeps its own parcel map. A tract near the line by Boulder City can be split in two county records, so look at the neighboring map too. If the land is near Las Vegas, our state page lists each bordering county map for Nevada.
Decoding the flood zone labels
An AE label carries a published BFE, while plain Zone A does not; that elevation drives building rules near Boulder City. Out toward Henderson, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the County Parcels in Nevada layer in ArcGIS Map Viewer to confirm you have the right parcel near Henderson.
What the map can't tell you
The acreage figure is an assessed number; just a licensed surveyor establishes the real boundary for a parcel near Mesquite. Owner names and values update on a schedule, so a recent sale near Henderson might lag behind.
A short flood checklist
Ask the seller about past flood claims on the property near Boulder City; getting a quote early avoids surprises.
Insurance, lenders and building
For a structure inside an A or V zone and the loan is federally backed or regulated, the lender will require flood insurance where the community participates in the National Flood Insurance Program, which applies near Boulder City as much as anywhere. Building or adding on near Mesquite in a mapped zone can trigger elevation rules; check with the county or town building office early.
Reading the legal description
Nevada follows the Public Land Survey System, so rural legal descriptions near Mesquite cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Mesquite vary in size. Write down the legal description for the tract near Boulder City before you request a deed or survey.
North Las Vegas: common questions

Generally, the base flood elevation is the water level expected in the 1% annual chance flood; surveyors near Boulder City use it often.
When is flood insurance required in North Las Vegas?

Does the county parcel map show flood zones in North Las Vegas?
A flood layer may appear in the County Parcels in Nevada layer in ArcGIS Map Viewer layer list, but FEMA's own map is the official source.
Is the parcel map a survey in North Las Vegas?

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
