Before an offer near Chattanooga, pull up the Tillman County flood zone map: the zone on that map shapes insurance, building rules and resale. In this Tillman County guide: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer.
The Tillman County flood zone map: start here
If you're looking near Chattanooga, the official source is FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. A tract near Loveland without an address can still be found: zoom in from US Route 62 and click the spot.
Pulling up a parcel
Go first to the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer; it covers every assessed parcel from Grandfield to Manitou. When a rural tract has no street number, pan along US Route 62 and select the outline, for land near Frederick included. For a home near Frederick, copy the parcel ID before closing the panel; every office in the county uses it to find the file.
What to request from a seller
If you're looking near Manitou, request whether the home has flooded before closing; getting a quote early avoids surprises.
Limits of the parcel data
Around Manitou, the acreage figure is a tax-roll number; only a licensed surveyor establishes the real lines on the ground. On ground around Grandfield, records update in batches, so a deed recorded last month can take weeks to appear.
Decoding the flood zone labels
Around Chattanooga, any A or V zone are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. In and around Hollister, shaded Zone X is moderate risk, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Frederick, so load it before you lose signal. A screenshot of the parcel near Davidson with its ID helps when you meet an owner or agent.
Sections, lots and bearings
Oklahoma follows the Public Land Survey System, which means a tract near Frederick is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Manitou odd-sized. Keep the legal description for land near Davidson when you talk to a surveyor.
Land on the county line
Tillman County borders Comanche County, Cotton County, Jackson County, Kiowa County, and Wichita County, TX, all with their own assessor records. Ground near Davidson that runs to the line can show up in two county records, so look at the neighboring map as well. In and around Davidson, the Platbookmapper state page links every bordering county map across Oklahoma.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer for the outline of the tract near Chattanooga.
Low spots and local drainage
Low-lying fields near Loveland may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Loveland is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Chattanooga are filed with the County Clerk. Out toward Manitou, bring the instrument number listed on the parcel record and the lookup takes minutes.
Tillman County in a few facts
Frederick holds the county offices, home to the main records offices. Other places on the map include Grandfield, Chattanooga, Davidson, and Hollister, each with its own cluster of lots. Roughly 6,869 people call Tillman County home (Census Bureau estimate, 2023) across about 871 square miles. Tillman County was organized in 1907, which matters when you trace an old farm's title.
Insurance, lenders and building
For a tract near Frederick, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. New construction in a floodplain near Davidson often needs a floodplain permit; call the permitting office before you plan.
