Common questions about Willacy County

01Where can I find a Willacy County parcel map and parcel data?

Free, from the source. The Texas Geographic Information Office's statewide StratMap parcel layer carries Willacy County's parcels from the county appraisal district, tax year 2026, collected in September 2026. The appraisal district's own property search and parcel map are listed under local sources above. TxGIO's DataHub also offers the county's parcels as a free shapefile download. Data resellers charge for copies of the same records. Add the layer to a Felt map by URL to filter, measure and share parcels with your team.

02Does Willacy County have zoning, and where is the zoning map?

Only inside city limits. Texas counties have no general zoning power, so unincorporated land in Willacy County is unzoned. Unzoned is not unregulated: Texas counties review subdivision plats and septic systems, and most permit development in the floodplain. Each city decides whether and how to zone. The city limits layer shows which city, if any, governs a site, and city planning, GIS and zoning pages are listed under local sources above.

03Where are Willacy County deed and plat records?

With the county clerk, not the appraisal district. Deeds, plats, easements and other real property records are recorded by the Willacy County Clerk; the appraisal district's records and parcel maps are for property tax, and its boundaries are approximate, not a survey. The clerk's office and its online records search are listed under local sources above. For a property's legal boundary, the recorded plat or a licensed surveyor's survey is the authority.

04How do I find the original survey or abstract for land in Willacy County?

Rural Texas land is described by its original survey, abstract number, and block and section. The Railroad Commission's public GIS viewer maps survey lines with their abstract numbers across the state, along with oil and gas wells and pipelines, and offers the same layers as free county downloads. The General Land Office holds the original survey and land grant files, searchable by county and abstract number, and 259 historic maps of Willacy County, from county maps to surveyors' working sketches. All are listed under local sources above.

05Which cities are in Willacy County?

3 cities and towns lie mostly inside Willacy County: Raymondville, Lyford and San Perlita. The Census Bureau's current boundaries for incorporated places map each one.

06Where is the Willacy County flood map, and how much is in a flood zone?

13.1% of Willacy County's land and inland water lies in FEMA's Special Flood Hazard Area, the floodplain with a 1% chance of flooding in any year (zone A and its subtypes such as AE, plus V zones on the coast). The county's flood map (FIRM) took effect on April 5, 2017. Flood zones are a planning screen, not a determination: check the effective FIRM for a specific property. FEMA's Map Service Center →

07Where are the high-voltage transmission lines in Willacy County?

HIFLD maps 74 miles of transmission line inside Willacy County: 44 mi at 138 kV and 30 mi at 345 kV. It marks 24 of those miles in service and records no status for the rest. The live map colours each line by voltage.

08What is the median household income in Willacy County?

$45,645, against $76,292 for Texas (ACS 2019–2023 5-year estimates). Across its 5 census tracts (2020 boundaries), tract medians run from $40,265 to $52,794, and the middle tract sits at $47,569.
