The Millard County flood zone map question tends to arrive at a bad moment: a lender's letter, an insurance quote, or a permit counter in Kanosh. Here's how to read FEMA's map for a Millard County, UT property and match it to the parcel record.
We'll cover finding a Millard County address on FEMA's map, what Zone A, AE and X mean, how the county viewer fits in, and what to do if the map looks wrong.
Where to see the official Millard County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in Holden. Search returns the effective FIRM panel for the spot in Millard County, plus any pending changes FEMA has posted. If the PDF panel for Millard County is hard to read, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery, which displays how much of a Millard County parcel sits inside the zone. Switch to the Utah State Parcels viewer and track down the same parcel near Fillmore. If the Millard County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.
Search Millard County parcels by owner, address or ID
There's no separate Millard County parcel site to hunt for; the Utah State Parcels viewer carries the county's parcels along with the rest of Utah. Use the search box for an address in Hinckley or a parcel number, or simply zoom in and click a parcel near Lynndyl. If the official address for the Millard County, UT map ever changes, our directory page carries the current link for Hinckley and the rest of the county.
High, moderate and minimal risk in Millard County
On the FIRM covering Millard County, zones that start with A or V are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. A surveyor working near Holden uses the base flood elevation printed for AE zones; unnumbered A zones don't have one. Land near Fillmore in shaded X (Zone B on older maps) sits in the moderate band between the 100-year and 500-year floods. Unshaded Zone X near Fillmore is minimal risk.
Where water shapes land in Millard County
In Millard County, look closest at tracts along Lake Bonneville and Sevier Lake. Don't assume a parcel near Fillmore is clear as its road frontage sits high. A creek near Fillmore that displays no detailed zone, which is why it's worth walking the ground after a heavy rain.
A short buyer checklist for Lynndyl
For a house near Hinckley, ask the seller for any elevation certificate on file and the current flood insurance declarations page. An agent working in Millard County can quote flood coverage once you know the zone for the lot near Hinckley.
Reading the fine print on a Millard County panel
The FIRM panel for Millard County carries an effective date; if it's old, ask the county floodplain office if new maps for land near Leamington are in progress. A floodway on a county panel marks the part of the floodplain that carries the main flow, and it's treated more strictly than the rest of the zone near Black Rock.
Insurance, permits and map changes
Insurance is the practical stake for a Millard County buyer. When a structure near Fillmore falls inside an A or V zone and carries a federally backed mortgage, a flood policy becomes a loan condition, as long as Millard County or the town participates in the NFIP. Outside the A zones around Fillmore, insurance is a choice, not a mandate, though a lender in Utah can still ask for it. When a Millard County homesite is on a rise inside a mapped zone, the owner can ask FEMA for a Letter of Map Amendment (LOMA), usually backed by an elevation certificate from a surveyor who works in Millard County. Placing fill on low ground near Holden usually needs a floodplain permit, and the building office serving Fillmore explains the steps.
