Weighing a property around Sonora? The Sutton County flood zone map tells you whether the lot falls inside a mapped floodplain, and it costs nothing to check. In this Sutton County guide: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Texas county CAD map.
The Sutton County flood zone map: start here
In and around Sonora, the official source is FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. Vacant ground around Sonora can still be found: pan from the closest town and click the spot.
The free map to start with
Go first to the Texas county CAD map; it includes each tax parcel in the county, Sonora included. For land near Sonora, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Sonora, save the parcel ID while you have it open; each records desk in the county will want it.
Limits of the parcel data
On ground around Sonora, listed acreage is an assessed number; only a licensed surveyor sets the real lines on the ground. If you're looking near Sonora, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Zones on the Sutton County flood zone map
For a tract near Sonora, any A or V zone are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For property near Sonora, shaded Zone X is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
What to request from a seller
For acreage around Sonora, request for any Elevation Certificate before closing; an insurance quote early avoids surprises.
Reading the legal description
Rural deeds near Sonora are often described by metes and bounds, which trace the boundary call by call.

Deeds, plats and who keeps them
In and around Sonora, the map is an index, not the title: recorded deeds, plats and easements for parcels in the county are filed with the County Clerk. For a parcel near Sonora, have ready the book and page listed on the parcel record so staff can find the deed fast.
Who handles what
