Getting started with the Weslaco GIS map

For acreage around Progreso Lakes, type a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near Mercedes, the parcel card typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
