Is that lot in Gordon in a flood zone? The Houston County flood zone map answer comes from FEMA, and it's free to look up. FEMA's free Flood Map Service Center and the Houston County parcel viewer answer it together.
Next: FEMA's search tool, the zone labels you'll see for Houston County, and how the parcel record confirms which tract you're on.
Where to see the official Houston County flood zone map
FEMA's official flood maps for Houston County are free at the FEMA Flood Map Service Center. The site returns the effective Flood Insurance Rate Map (FIRM) panel covering that Ashford location, which you can view or download. For an irregular lot near Dothan, the National Flood Hazard Layer viewer is easier to use; zoom to the piece of ground near Dothan and click. Switch to the Houston County parcel viewer and find the same piece of ground near Dothan. Laying the county parcel outline beside the FEMA shading displays whether a homesite near Dothan sits above or inside the zone.
Opening the Houston County parcel viewer
Houston County publishes its parcels on the Houston County parcel viewer, free to use for a lot in Gordon or a piece of ground near Cottonwood. Use the search box for an address in Gordon or a parcel number, or simply zoom in and click a piece of ground near Cottonwood. For a backup route to the map covering Cottonwood, our Houston County directory entry keeps the link current.
What the flood zone letters mean
On the FIRM covering Houston County, zones that start with A or V are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). Where a Houston County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there is not one. Shaded Zone X around Ashford is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near Dothan is minimal risk.
Recorded documents in Houston County, Alabama
Deeds and recorded plats for Houston County are filed with the county probate office. Like every Alabama county, Houston County records deeds through its probate court's recording office rather than a county clerk. Easements and access rights near Gordon live in recorded documents, so read the deed, not just the county map.
Towns and land across Houston County
Town lots cluster around Dothan, the county seat, and Ashford, Avon, Columbia, and Cottonwood. Unincorporated communities in Houston County, including Ardilla, Big Creek, and Crosby, display up as small groups of parcels along the roads. Roughly 580 square miles of land and about 108,462 residents (2023 estimate) make up Houston County. The Houston County map mixes subdivision lots near Cottonwood with farm and wooded tracts farther out. Houston County was organized in 1903, so deeds for older farms near Avon can run back a long way.
Unmapped creeks in Houston County
Small streams and ditches near Ashford may not be studied in detail, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
Near the Houston County line
Houston County borders Dale County, Geneva County, Henry County, Jackson County, FL, and Early County, GA, and each keeps its own parcel map and records. Our Alabama page links each map neighboring Houston County.
Insurance, permits and map changes
The zone displays up again when a loan on a house near Dothan is underwritten. When a structure near Dothan is mapped in a high-risk zone and secures a loan from a federally regulated or insured lender, federal rules call for flood insurance under the Flood Disaster Protection Act, wherever the community joins the NFIP. In Zone X near Ashford, federal rules do not require a policy; pricing a policy for land near Dothan is still worth a call. When a county homesite is on a rise inside a mapped zone, a Letter of Map Amendment request is the formal route; a surveyor near Dothan can supply the elevation data. New construction in a Houston County Special Flood Hazard Area has to meet local floodplain rules, so call the county or the town office in Ashford before work starts.
