Weighing a property around Simms? Checking the Deaf Smith County flood zone map reveals whether FEMA puts it in a high-risk zone, and no account is needed. What this Deaf Smith County guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Deaf Smith CAD interactive map.
Checking the Deaf Smith County flood zone map step by step
If you'd rather pan and zoom, use the National Flood Hazard Layer viewer, which lets you click a spot and read its zone, whether the land is near Milo Center or elsewhere in the county. Vacant ground around Milo Center can still be found: zoom in from Interstate 40 and click inside the land.
The free map to start with
Parcels around Simms can be looked up on the Deaf Smith CAD interactive map, free to use and open without a login. For a tract near Glenrio, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. With a lot near Milo Center, the parcel card typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Neighboring parcel maps
Deaf Smith County meets Curry County, NM, Quay County, NM, Castro County, Oldham County, and Parmer County, all with their own assessor records. Acreage along the edge near Hereford may be split across two assessors' files, so look at the adjacent map before you assume the acreage. On ground around Simms, our state page links every neighboring county map for Texas.
Backing up the map with records
For property near Hereford, the map is an index, not the title: deeds, plats and easements for parcels in the county are kept by the County Clerk. For a parcel near Simms, have ready the book and page shown in the record panel to skip a name search.
Places you'll see on the map
Hereford is the county seat, where most land records are kept. You'll also find Dawn, Ford, Glenrio, and Milo Center, where town lots give way to larger tracts. Around 18,347 people live in Deaf Smith County (Census estimate, 2023) spread over some 1,497 square miles. Deaf Smith County was formed in 1890, and some chains of title near Simms are long.
A word on accuracy
Closer to Ford, acreage on the record is an estimate; just a licensed surveyor can set the real lines on the ground. For property near Ford, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Reading A, AE and X
In and around Milo Center, zones beginning with A or V are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. Closer to Hereford, shaded Zone X is moderate risk, roughly the 100- to 500-year range; plain X, or C on older maps, means minimal mapped risk.
What to request from a seller
If the land is near Milo Center, ask the seller about past flood claims before closing; getting a quote early avoids surprises.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so pair it with the Deaf Smith CAD interactive map to see exactly which lot near Milo Center you're looking at.
Water near Ford
Small streams around Hereford aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Glenrio can limit building too; check the National Wetlands Inventory mapper for a first look.
Lenders and permits
For a structure inside an A or V zone and a federally regulated lender is involved, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, whether the land is near Dawn or elsewhere in the county. Building or adding on near Dawn in a mapped zone can trigger elevation rules; check with the county or town building office before you plan.
Who handles what
Questions about value or the owner field for land near Glenrio go to the appraisal district, the office behind the parcel record. Building or septic questions for a lot near Hereford go to planning, building or health offices, and the answer depends on jurisdiction.
Sections, lots and bearings
Tracts outside towns near Dawn are often described by metes and bounds, which trace the boundary call by call. Platted lots around Glenrio are typically described by lot and block, making them easier to find. Write down the legal description for the tract near Hereford when you talk to a surveyor.
