Weighing a property around Santaquin? The Nephi flood zone map tells you whether the lot falls inside a mapped floodplain, and the lookup is free. What this Nephi guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Utah State Parcels viewer.
The Nephi flood zone map: start here
The official source is FEMA's Flood Map Service Center: type an address near Levan, then open the map view for that panel. Vacant ground around Mona can still be found: pan from the closest town then click the parcel area.
Opening the official parcel viewer
Go first to the Utah State Parcels viewer; it includes each tax parcel from Mona to Rocky Ridge. For property near Mona, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. If you're looking near Rocky Ridge, write down the parcel ID while you have it open; every office in the county will want it.
Juab County in a few facts
Nephi serves as the county seat, which is where the courthouse records live. You'll also find Mona, Levan, Rocky Ridge, and Santaquin, where town lots give way to larger tracts. Around 13,023 people call Juab County home (Census Bureau estimate, 2023) on some 3,392 square miles. Juab County was organized in 1852, and some chains of title near Santaquin are long. Features like Fish Springs National Wildlife Refuge make handy reference points on the map near Santaquin.
Nephi and the county around it
Nephi sits in Juab County, Utah, which means parcel data comes from the county. Nephi is also the county seat, so deeds and plats are filed in town. For land near Levan, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the city limits toward Eureka usually falls under county rules instead.
Neighboring parcel maps
Juab County borders White Pine County, NV, Millard County, Sanpete County, Tooele County, and Utah County, all with their own assessor records. Acreage along the edge near Levan can be split in two county records, so open the adjacent map too. The Platbookmapper state page lists each bordering county map across Utah.
What the zone letters mean
An AE label comes with a base flood elevation, while plain Zone A does not; that elevation drives building rules near Mona. For a tract near Mona, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so open the Utah State Parcels viewer next for the outline of the tract near Rocky Ridge.
Water near Santaquin
Small streams around Santaquin may not have detailed mapping, so look for water marks and debris lines. Wetlands near Santaquin can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
What the map can't tell you
The acreage figure is an assessed number; only a licensed surveyor sets the real boundary on land around Mona. If the land is near Rocky Ridge, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Insurance, lenders and building
For a structure inside an A or V zone and a federally regulated lender is involved, the lender will require flood insurance in communities in the NFIP, whether the land is near Rocky Ridge or elsewhere in the county. Remodeling a house in a zone near Santaquin can trigger elevation rules; call the permitting office early.
A short flood checklist
Request whether the home has flooded on the property near Mona; an insurance quote early avoids surprises.
How land is described here
Utah follows the Public Land Survey System, so deeds around Mona reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Levan odd-sized. Keep the legal description for land near Eureka when you talk to a surveyor.
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 Rocky Ridge as much as anywhere. Around Mona, have ready the document number shown in the record panel and the lookup takes minutes.
Quick answers
When is flood insurance required near Rocky Ridge?
Good question; for a building near Levan in an A or V zone with a federally backed or regulated mortgage, it's generally required; outside those zones it's your call.
Is AE a high-risk flood zone for land near Mona?
It depends, but an AE zone has a 1% annual chance of flooding and a base flood elevation, which shapes building rules near Rocky Ridge.
How often are flood maps updated around Santaquin?
Good question; zones near Mona can shift when FEMA updates a panel, so look at the panel date.
What if the flood map is wrong for my lot near Rocky Ridge?
Usually, FEMA's LOMA process is the usual route when a building near Rocky Ridge sits above the base flood elevation; it starts with an elevation survey.
Where is the legal description for land near Rocky Ridge?
Out toward Mona, deeds use lot and block, metes and bounds or survey descriptions, and the parcel record often summarizes it.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
