Ahead of any purchase around Tyrone, look at the Texas County flood zone map: FEMA's zone label affects insurance, building rules and resale. In this Texas County guide: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
The Texas County flood zone map: start here
If you'd rather pan and zoom, try the National Flood Hazard Layer viewer, which lets you click a spot and read its zone, which applies near Hough as much as anywhere. A tract near Four Corners without an address is still easy to locate: search the nearest road and click inside the land.
Getting to the right map
Go first to the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer; it covers every tax parcel around Eva and Optima. For property near Hooker, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a tract near Hardesty, save the parcel ID from that panel; every office in the county asks for it first.
A quick look at the area
Guymon is the county seat, which is where the courthouse records live. You'll also find Hooker, Goodwell, Hardesty, and Optima, each with its own cluster of lots. About 20,371 people live in Texas County (Census estimate, 2023) across about 2,041 square miles. Texas County dates to 1907, so old deeds can run back a long way. Features like Optima Lake and Optima National Wildlife Refuge help you orient on the aerial.
Reading the legal description
Oklahoma is laid out under the Public Land Survey System, so rural legal descriptions near Four Corners cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Hardesty odd-sized. Copy the legal description from the record for the parcel near Optima Lake for any title or survey request.
Water near Optima National Wildlife Refuge
Small streams around Optima Lake aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Optima Lake can limit building too; check the National Wetlands Inventory mapper for a first look.
Zones on the Texas County flood zone map
An AE label comes with a base flood elevation, and an unnumbered A zone has none; surveyors near Hough use that number. With a lot near Four Corners, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
What to request from a seller
Ask the seller for any Elevation Certificate for the house near Optima National Wildlife Refuge; an insurance quote early avoids surprises.
The paper trail behind a parcel
Before you sign anything, request the recorded deed from the County Clerk; the parcel line is a drawing of it, whether the land is near Optima Lake or elsewhere in the county. For a tract near Optima Lake, use the instrument number from the tax record so staff can find the deed fast.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer too for the outline of the tract near Hough.
What the map can't tell you
In and around Four Corners, listed acreage is an assessed number; just a licensed surveyor can set the real boundary on the ground. For land near Guymon, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Eva, but coverage can be spotty out of town. A screenshot of the parcel near Optima Lake with its ID helps when you meet an owner or agent.
Which office to call
Deeds, mortgages and recorded plats for land near Optima are with the County Clerk, often with an online index. Zoning, permits and septic questions near Hardesty need the planning or permitting office, and the answer depends on jurisdiction.
Money questions tied to the zone
With a lot near Hooker, an Elevation Certificate from a surveyor helps: it records the building's elevation against the base flood. New construction in a floodplain near Guymon can trigger elevation rules; check with the county or town building office before you plan.
Texas County: common questions
How often are flood maps updated in Texas County?
Short answer: a new study can move a zone line near Hardesty, so look at the panel date.
What is a base flood elevation near Baker?
It depends, but a BFE near Four Corners tells builders how high the lowest floor should be; local rules may require building above it.
Is my property near Tyrone in a flood zone?
Generally, look up the spot near Four Corners in FEMA's National Flood Hazard Layer viewer; no account is needed.
Can I see flood zones on the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer around Tyrone?
Good question; the parcel map near Eva might show FEMA zones, though it can lag behind FEMA's current panels.
Is the parcel map a survey around Hough?
For acreage around Goodwell, parcel lines are tax drawings, not surveys; a survey sets the real corners

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.
