An Emery County flood zone map check belongs in the due diligence for any Emery County property, from a house lot in Ferron to farm ground near Huntington. You can check it yourself for any Ferron address in a few minutes.
Next: FEMA's search tool, the zone labels you'll see for Emery County, and how the parcel record confirms which tract you're on.
How to use the Emery County flood zone map
The authoritative source for an Emery County flood zone map is FEMA, so begin at the FEMA Flood Map Service Center. If a piece of ground near Castle Dale has no street number yet, search the nearest road and pan to it. For an irregular lot near Castle Dale, try FEMA's National Flood Hazard Layer viewer, so you can see whether the shading reaches a house near Castle Dale. Next, the Emery County ArcGIS parcel map confirms which Emery County parcel you're looking at. Match the Emery County lines and acreage to the FEMA view, since flood maps do not draw property lines in detail.
Finding the tract on the Emery County map
Emery County publishes its parcels on the Emery County ArcGIS parcel map, which runs on an Esri ArcGIS web map, free to use for a lot in Castle Dale or a piece of ground near Clawson. Most people track down their Emery County tract fastest by searching an address in Clawson, then clicking the outline. For a backup route to the map covering Clawson, our Emery County directory entry keeps the link current.
Emery County land records
The parcel layer for Emery County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). Copy the parcel ID and legal description from the county record well before you request a deed for land near Castle Dale.
Reading the zones on an Emery County flood map
For a lot in Huntington, the label matters more than the color: A and V zones are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Where an Emery County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. Shaded Zone X around Huntington is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded X (or C) on the Emery County panel means minimal risk.
Creeks, rivers and low ground in Emery County
Parcels touching Green River, San Rafael River and Quitchupah Creek deserve a FEMA check before anything else in the county. On many tracts close to Huntington, the zone covers the low ground by the water while the homesite near the road is outside it. Small streams and ditches near Huntington may not be studied in detail, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
What a flood zone means for an Emery County buyer
Insurance is the practical stake for an Emery County buyer. When a structure near Castle Dale is mapped in a high-risk zone and is financed by a regulated or federally insured lender, the lender must require flood coverage, as long as Emery County or the town participates in the NFIP. Outside the A zones around Castle Dale, coverage is optional; pricing a policy for land near Castle Dale is still worth a call. Where a structure near Huntington looks higher than the shading suggests, FEMA's LOMA process allows a review, generally backed by an elevation certificate from a surveyor who works in the county. New construction in an Emery County Special Flood Hazard Area generally needs a floodplain permit, and the building office serving Castle Dale explains the steps.

Emery County, UT: common questions
Is there a floodplain layer in the Emery County ArcGIS parcel map?
Look for a flood or floodplain layer in the Emery County viewer, then verify the zone with FEMA.
Does a 100-year floodplain near Ferron flood only once a century?
Not at all; an Emery County tract in that zone faces a 1-percent annual chance, so floods can come in back-to-back years.
Where do I get an elevation certificate in Emery County?
A licensed land surveyor or engineer prepares it, and the building office serving Huntington may already have one on file for newer construction.
What if FEMA's map is wrong about my house near Ferron?
FEMA reviews requests such as a LOMA for Emery County properties; start with an elevation certificate.
Is Zone AE near Ferron high risk?
Yes, a piece of ground near Ferron in Zone AE is high risk: a 1-percent-annual-chance floodplain where FEMA lists a base flood elevation.
My house near Ferron is in Zone X. Is insurance required?
FEMA does not require it for a Zone X lot in Huntington, but coverage is available and some lenders ask for it.
