Weighing a property around Yerington? Checking the Fernley flood zone map reveals whether FEMA puts it in a high-risk zone, and it costs nothing to check. This Fernley guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the County Parcels in Nevada layer in ArcGIS Map Viewer.
Where the Fernley flood zone map lives
Flood zones come from FEMA's Flood Map Service Center: type an address near Yerington, and pick the FIRMette or map view. A tract near Dayton without an address can still be found: zoom in from Interstate 11 then click the parcel area.
Where the parcel data lives
Your first stop is the County Parcels in Nevada layer in ArcGIS Map Viewer; it maps each tax parcel around Dayton and Yerington. If you only know roughly where the land is, pan along Interstate 11 and click the parcel itself. For a home near Dayton, the parcel card usually lists the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
What the map can't tell you
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Yerington often sits a few yards off the line on screen. On ground around Dayton, owner names and values update on a schedule, so a deed recorded last month may not show yet.
The paper trail behind a parcel
When the details count, get the recorded deed from the County Recorder; the parcel map near Yerington only summarizes it. For property near Yerington, have ready the document number from the tax record and the lookup takes minutes.
A quick look at the area
Dayton serves as the county seat, where most land records are kept. Roughly 62,583 people live in Lyon County (Census Bureau estimate, 2023) spread over about 2,003 square miles. Lyon County was formed in 1861, which matters when you trace an old farm's title. Features like Toiyabe National Forest are easy to spot when you zoom out from Dayton.
A short flood checklist
Ask the listing agent about past flood claims for the house near Dayton; an insurance quote early keeps the budget honest.
Fernley, NV: the basics
Fernley sits in Lyon County, Nevada, and the county assessor maps its lots. Local government in Fernley handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Land beyond the city limits out by Yerington generally follows county rules rather than the town's.
On site with the map
Most viewers work in a phone browser, handy when you're parked on a road near Dayton, but coverage can be spotty out of town. A screenshot of the parcel near Yerington with its ID helps when you meet an owner or agent.
What the zone letters mean
Zone AE comes with a base flood elevation, which plain A zones lack; builders around Yerington design to it. Out toward Yerington, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so check the County Parcels in Nevada layer in ArcGIS Map Viewer too to confirm you have the right parcel near Dayton.
Money questions tied to the zone
For a parcel near Dayton, ask for an Elevation Certificate: it compares the building to the BFE. Remodeling a house in a zone near Yerington can trigger elevation rules; ask the local floodplain administrator before you plan.
Neighboring parcel maps
Lyon County touches Mono County, CA, Churchill County, Douglas County, Mineral County, and Storey County, all with their own assessor records. A tract near the line by Yerington may be split in two county records, so look at the neighboring map too. Out toward Yerington, the Platbookmapper state page links every bordering county map across Nevada.
Beyond the mapped zones
Low-lying fields near Yerington may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Dayton is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Offices that can help
Deeds, mortgages and recorded plats for land near Yerington sit in the index kept by the County Recorder, often with an online index. Building or septic questions for a lot near Yerington are for the local planning and health departments, and the answer depends on jurisdiction.
