Before an offer near Coldwater, check the Dalhart flood zone map: the zone on that map shapes insurance, building rules and resale. Covered here for Dalhart: finding the address on FEMA's map, decoding A, AE and X, and matching it with the county parcel viewer.
Where the Dalhart flood zone map lives
The official source is FEMA's Flood Map Service Center: search an address around Coldwater, and choose the dynamic map. A tract near Coldwater without an address can still be found: zoom in from the nearest road and click inside the land.
Opening the official parcel viewer
Begin with the Dallam CAD interactive map; it maps every tax parcel in the county, Coldwater included. Closer to Texline, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Texline, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
City limits and county records
Dalhart is part of Dallam County, Texas, so its parcels are on the county's map. As the county seat, Dalhart hosts the courthouse, handy when you need recorded documents. For acreage around Coldwater, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the town limits out by Texline generally answers to county rules instead.
On site with the map
Most viewers work in a phone browser, useful out on a road near Texline, so load it before you lose signal. A saved image of the lot near Texline and its lines is a good backup.
Beyond the mapped zones
Low-lying fields near Coldwater may not have detailed mapping, so walk the land after rain. Marshy spots near Texline can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
What the zone letters mean
Closer to Coldwater, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a parcel near Coldwater, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Dallam CAD interactive map too to see exactly which lot near Texline you're looking at.
What to request from a seller
Ask the listing agent whether the home has flooded on the property near Texline; getting a quote early keeps the budget honest.
How land is described here
Older tracts around Coldwater are often described by metes and bounds, listing bearings, distances and landmarks. Town lots near Coldwater usually use lot and block from a recorded plat instead, which is simpler to follow. Write down the legal description for the tract near Texline when you talk to a surveyor.
Lenders and permits
Closer to Coldwater, get the Elevation Certificate if one exists: it compares the building to the BFE. Remodeling a house in a zone near Coldwater usually means extra permit review; ask the local floodplain administrator before you plan.
The paper trail behind a parcel
For anything that matters, get the recorded deed through the County Clerk; the viewer just points to it, whether the land is near Coldwater or elsewhere in the county. If you're looking near Coldwater, have ready the book and page from the tax record and the lookup takes minutes.
Offices that can help
Questions about value or the owner field for land near Texline belong with the appraisal district, the office behind the parcel record. Questions about what you can build around Coldwater need the planning or permitting office, depending on whether the land is inside town limits.
Neighboring parcel maps
Dallam County touches Union County, NM, Cimarron County, OK, Hartley County, Moore County, and Sherman County; every one of them runs a separate parcel map. Ground near Texline that runs to the line can show up across two assessors' files, so look at the neighboring map before you assume the acreage. For a tract near Texline, our state page links every bordering county map for Texas.
Limits of the parcel data
The acreage figure is a tax-roll number; just a licensed surveyor establishes the real boundary for a parcel near Texline. For property near Coldwater, records update in batches, so a deed recorded last month can take weeks to appear.

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.
