For any lot around Progreso, the Donna GIS map shows parcel boundaries plus basic tax data. This Donna guide covers: which viewer to open, the fastest ways to search, and what to double-check with records.
Opening the Donna GIS map
Parcel maps here are usually run by the county, not the town, and for Donna that means the appraisal district map.
Where the parcel data lives
Go first to the appraisal district map; it maps every assessed parcel in the county, Mercedes included. For a parcel near Progreso Lakes, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Weslaco, the record panel typically gives the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Next door to Hidalgo County
Hidalgo County touches Brooks County, Cameron County, Kenedy County, Starr County, and Willacy County; every one of them runs a separate parcel map. A tract near the line by Weslaco can be split in two county records, so look at the neighboring map as well. For a tract near Alamo, our state page links every bordering county map for Texas.
Keeping a record
Save a screenshot of the lot near Progreso Lakes and its record panel, so you have it when calling an office.
Browser tips
If the viewer stalls on a phone near Progreso, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
What the map can't tell you
Acreage on the record is an estimate; just a licensed surveyor can set the real lines for a parcel near San Juan. Around Weslaco, records update in batches, so a deed recorded last month might lag behind.
Field tips
Most viewers work in a phone browser, useful out on a road near Progreso, so load it before you lose signal. A screenshot of the parcel near Progreso with its ID keeps working without signal.
Donna, TX: the basics
Donna is part of Hidalgo County, Texas, and the county assessor maps its lots. For land near San Juan, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits toward Weslaco usually follows county rules rather than the town's.
Searching the map
For a house in Donna, search the street address; owner search often wants the surname first. With a lot near Mercedes, searching by parcel number never misses, and it carries over to every office in the county.
Places you'll see on the map
Edinburg holds the county offices, home to the main records offices. Smaller places on the map include Weslaco, Alamo, Progreso, and San Juan. Roughly 898,471 people call Hidalgo County home (Census estimate, 2023) spread over about 1,571 square miles. Hidalgo County dates to 1852, and some chains of title near Weslaco are long. Places such as Lower Rio Grande Valley National Wildlife Refuge are easy to spot when you zoom out from Mercedes.
Where the recorded documents are
The map is an index, not the title: deeds, plats and easements covering ground around Progreso sit with the County Clerk. On ground around Mercedes, have ready the instrument number shown in the record panel and the lookup takes minutes.
Which office to call
Questions about value or the owner field for land near Mercedes are handled by the appraisal district, which maintains the tax roll. Zoning, permits and septic questions near Weslaco go to planning, building or health offices, depending on whether the land is inside town limits.
Beyond the parcel lines
Near Weslaco, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
Reading the legal description
Rural deeds near Progreso commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Platted lots around Progreso Lakes usually use lot and block from a recorded plat instead, which is simpler to follow. Keep the legal description for land near Mercedes before you request a deed or survey.
Owner, value and acreage
Recent sales on nearby lots around Weslaco are a useful starting point; an appraiser is the real authority.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
