Before you buy or build near Gerlach, look at the Washoe County flood zone map: a mapped flood zone changes insurance, building rules and resale. This Washoe County 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.
Checking the Washoe County flood zone map step by step
If the land is near Empire, flood zones come from FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. A tract near Reno without an address is still easy to locate: zoom in from US Route 395 and click inside the land.
The free map to start with
Begin with the County Parcels in Nevada layer in ArcGIS Map Viewer; it maps every assessed parcel from Cold Springs to Reno. If you only know roughly where the land is, pan along US Route 395 until the lines appear, then click inside the one you want, for land near Golden Valley included. With a lot near Gerlach, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Low spots and local drainage
Small streams around Truckee River aren't always studied in detail, so look for water marks and debris lines. Wet ground around Crystal Bay is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Decoding the flood zone labels
An AE label includes a base flood elevation (BFE), and an unnumbered A zone has none; surveyors near Crystal Bay use that number. If the land is near Crystal Bay, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Offices that can help
Questions about value or the owner field for land near Galena Creek Regional Park belong with the County Assessor, which maintains the tax roll. Building or septic questions for a lot near Sparks are for the local planning and health departments, depending on whether the land is inside town limits.
What to request from a seller
If you're looking near Gerlach, ask the listing agent about past flood claims before closing; an insurance quote early avoids surprises.
Lining it up with the parcel map
FEMA doesn't draw property lines, so open the County Parcels in Nevada layer in ArcGIS Map Viewer next to see exactly which lot near Galena Creek Regional Park you're looking at.
Lenders and permits
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, mandatory purchase rules apply in communities in the NFIP, which applies near Galena Creek Regional Park as much as anywhere. Remodeling a house in a zone near Sparks usually means extra permit review; call the permitting office early.
Backing up the map with records
For anything that matters, get the recorded deed from the County Recorder; the parcel line is a drawing of it, which applies near Truckee River as much as anywhere. Closer to Galena Creek Regional Park, use the book and page shown in the record panel and the lookup takes minutes.
Next door to Washoe County
Washoe County meets Lassen County, CA, Modoc County, CA, Nevada County, CA, Placer County, CA, and Sierra County, CA, all with their own assessor records. Acreage along the edge near Empire can be split across two assessors' files, so look at the neighboring map before you assume the acreage. For land near Sparks, our state page lists each neighboring county map across Nevada.
Sections, lots and bearings
Nevada uses the Public Land Survey System, so deeds around Truckee River reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Galena Creek Regional Park vary in size. Copy the legal description from the record for the parcel near Truckee River for any title or survey request.
