What the flood zone letters mean
Any Uinta 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. Where an Uinta County tract lists Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. Land near Bear River in shaded X (Zone B on older maps) is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded X (or C) on the Uinta County panel means minimal risk.
Towns and land across Uinta County
Town lots cluster around Evanston, the county seat, and Bear River, Lyman, and Mountain View. Smaller places such as Aspen, Millburne, and Robertson appear on the county map as little clusters of lots. Roughly 2,082 square miles of land and about 20,745 residents (2023 estimate) make up Uinta County. Outside Lyman, most of the county map is farm, ranch or timber ground with large, irregular tracts.
Unmapped creeks in Uinta County
A creek near Bear River that lists no detailed zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
What a flood zone means for an Uinta County buyer
Here's why the zone matters at a closing in Evanston. When an Uinta County home falls inside an A or V zone and is financed by a regulated or federally insured lender, flood insurance is mandatory, as long as Uinta County or the town participates in the NFIP. In Zone X near Evanston, coverage is optional; pricing a policy for land near Bear River is still worth a call. If a building near Bear River sits above the flood line, FEMA's LOMA process allows a review, generally backed by an elevation certificate from a surveyor who works in the county. Placing fill on low ground near Evanston generally needs a floodplain permit, and the building office serving Bear River explains the steps.
Uinta County, WY: common questions
Where do I get an elevation certificate in Uinta County?
Hire a licensed surveyor or engineer who works in Uinta County; ask the local floodplain office first in case one exists.
What if FEMA's map is wrong about my house near Evanston?
FEMA reviews requests such as a LOMA for Uinta County properties; start with an elevation certificate.
My house near Evanston is in Zone X. Is insurance required?
Not under federal rules; Zone X in Uinta County is outside the Special Flood Hazard Area, though a lender can still require coverage.
What is a base flood elevation for an Uinta County property?
Near Evanston, it's the projected water surface in the base flood, and a surveyor compares the building near Mountain View to it.

Often, but local floodplain rules apply; ask the county or town building office in Mountain View well before you buy.
