Where to see the official Maverick County flood zone map
Open the FEMA Flood Map Service Center and type a county street address, say one in Chula Vista. Download the FIRM panel FEMA lists as effective for that part of Maverick County. For an irregular lot near Eidson Road, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery; zoom to the parcel near Eidson Road and click. Switch to the Texas county CAD map and locate the same parcel near Eidson Road. The Maverick County record gives the parcel ID and legal description that an insurer or lender near Chula Vista may ask for.
Finding the tract on the Maverick County map
For land around Eagle Pass, open the Texas county CAD map (the ProdigyCAD maps portal); it is the map Maverick County itself publishes. Search the county appraisal map by owner, address or property ID; the pop-up for a parcel near Eidson Road displays the account and legal description. Bookmark our Maverick County page too; it tracks the official Texas link if it moves and lists the maps around Eidson Road.
Zone A, AE and X in plain English
Any Maverick County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, meaning FEMA estimates a 1-percent annual chance of flooding. Where a Maverick County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. Land near Eidson Road in shaded X (Zone B on older maps) is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded X (or C) on the Maverick County panel means minimal risk.

For a parcel near Chula Vista, the appraised value is set by the county appraisal district, which Texas law keeps separate from county government. Easements and access rights near Chula Vista live in recorded documents, so read the deed, not just the county map.

Insurance, permits and map changes

In Zone X near Chula Vista, insurance is a choice, not a mandate, although some lenders require it anyway. If a building near Eidson Road sits above the flood line, a Letter of Map Amendment request is the formal route; a surveyor near Eidson Road can supply the elevation data. New construction in a Maverick County Special Flood Hazard Area commonly requires a permit and an elevation check, and the building office serving Eidson Road explains the steps.
