Where to see the official Churchill County flood zone map
Start at the FEMA Flood Map Service Center and enter the property address in Cold Springs or anywhere else in the county. Download the FIRM panel FEMA lists as effective for that part of Churchill County. On acreage outside Cold Springs, the National Flood Hazard Layer viewer is easier to use, which displays how much of a county parcel sits inside the zone. Next, the County Parcels in Nevada layer in ArcGIS Map Viewer confirms which Churchill County parcel you're looking at. Match the Churchill County lines and acreage to the FEMA view, since flood maps don't draw property lines in detail.

The lay of the land around Fallon
Fallon is the seat of Churchill County and the hub for its land records. Unincorporated communities in the county, including Fallon Station, Cold Springs, and Dixie Valley, display up as small groups of parcels along the roads. Roughly 4,950 square miles of land and about 25,803 residents (2023 estimate) make up Churchill County. Outside Fallon, most of the county map is farm, ranch or timber ground with large, irregular tracts.
Reading the zones on a Churchill County flood map
Any Churchill County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, meaning FEMA estimates a 1-percent annual chance of flooding. Zone AE near Fallon means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. If a Churchill County parcel displays shaded Zone X, it sits in the moderate band between the 100-year and 500-year floods. Unshaded X (or C) on the Churchill County panel means minimal risk.
Low ground and small streams around Cold Springs

What a flood zone means for a Churchill County buyer
Lenders watch the zone closely on Churchill County properties. If a barn or house outside Cold Springs falls inside an A or V zone and secures a loan from a federally regulated or insured lender, a flood policy becomes a loan condition, provided the community near Cold Springs takes part in the National Flood Insurance Program. For a Churchill County home in shaded or unshaded X, insurance is a choice, not a mandate, although some lenders require it anyway. When a Churchill County homesite is on a rise inside a mapped zone, a Letter of Map Amendment request is the formal route, supported by elevation data from a professional surveyor. Adding on to a house near Fallon inside the zone often requires a permit and an elevation check, so call the county or the town office in Cold Springs before work starts.
