Getting started with the San Augustine County flood zone map
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 US Route 96 as much as anywhere. A tract near US Route 96 without an address is still easy to locate: pan from the closest town and click inside the land.
The free map to start with
Go first to the San Augustine County parcel viewer; it includes each tax parcel around US Route 96 and Benina. If you're looking near US Route 96, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. Out toward Broaddus, copy the parcel ID while you have it open; each records desk in the county asks for it first.
Getting your bearings
San Augustine is the county seat, where most land records are kept. You'll also find Black Ankle, Benina, Broaddus, and Angelina National Forest, each with its own cluster of lots. About 7,833 people live in San Augustine County (Census estimate, 2023) spread over some 531 square miles. San Augustine County dates to 1837, and some chains of title near Black Ankle are long. Landmarks such as Angelina National Forest are easy to spot when you zoom out.
Where the recorded documents are
Before you sign anything, request the recorded deed through the County Clerk; the parcel map near US Route 96 only summarizes it. Around US Route 96, have ready the document number listed on the parcel record to skip a name search.
A short flood checklist
In and around US Route 96, request whether the home has flooded before closing; getting a quote early keeps the budget honest.
On site with the map
The parcel map usually runs in a mobile browser, handy when you're parked on a road near US Route 96, but coverage can be spotty out of town. A saved image of the lot near Broaddus and its lines is a good backup.
What the zone letters mean
Zone AE carries a published BFE, and an unnumbered A zone has none; surveyors near Angelina National Forest use that number. Out toward Angelina National Forest, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Matching the zone to the lot lines
Where a floodplain cuts across acreage near US Route 96, what matters is where the building sits.
Who handles what
Questions about value or the owner field for land near US Route 96 belong with the appraisal district, which maintains the tax roll. Questions about what you can build around US Route 96 need the planning or permitting office, town or county, depending on location.
Money questions tied to the zone
Closer to US Route 96, ask for an Elevation Certificate: it can change the insurance price a lot. New construction in a floodplain near Black Ankle usually means extra permit review; ask the local floodplain administrator before you plan.
How land is described here
Older tracts around US Route 96 commonly use metes-and-bounds descriptions, which trace the boundary call by call. Platted lots around US Route 96 refer to a recorded plat, making them easier to find. Keep the legal description for land near US Route 96 for any title or survey request.
Water near US Route 96

What the map can't tell you
