Ahead of any purchase around South Fork Estates, check the Jim Hogg County flood zone map: a mapped flood zone changes insurance, permits and resale. This Jim Hogg County guide covers: the free FEMA tools, what each zone label means, when insurance is required and what a LOMA is.
Getting started with the Jim Hogg County flood zone map
For parcel-by-parcel detail, open the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, and that holds around South Fork Estates too. Rural land near South Fork Estates with no street number can still be found: zoom in from the nearest road and click the spot.
Getting to the right map
Begin with the Texas county CAD map; it covers each assessed parcel from Las Lomitas to South Fork Estates. If you only know roughly where the land is, pan along the nearest road until the lines appear, then click inside the one you want, for land near Agua Nueva included. If you're looking near Las Lomitas, the record panel usually lists the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
A short flood checklist
Ask the listing agent about past flood claims for the house near Agua Nueva; an insurance quote early keeps the budget honest.
What the zone letters mean
For property near Agua Nueva, any A or V zone are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For a tract near Hebbronville, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
When a parcel crosses a boundary
Jim Hogg County meets Brooks County, Duval County, Starr County, Webb County, and Zapata County, all with their own assessor records. A tract near the line by South Fork Estates may show up in two county records, so look at the neighboring map before you assume the acreage. On ground around Las Lomitas, the Platbookmapper state page links every neighboring county map for Texas.
What the map can't tell you
For a tract near Guerra, the acreage figure is an assessed number; just a licensed surveyor sets the real lines on the ground. Out toward Guerra, records update in batches, so a deed recorded last month might lag behind.
On site with the map
Most viewers work in a phone browser, useful out on a road near Thompsonville, so load it before you lose signal. A printout of the tract near Las Lomitas is a good backup.
The paper trail behind a parcel
When the details count, request the recorded deed from the County Clerk; the parcel line is a drawing of it, which applies near Las Lomitas as much as anywhere. If the land is near Agua Nueva, use the book and page listed on the parcel record and the lookup takes minutes.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so open the Texas county CAD map next to confirm you have the right parcel near Las Lomitas.
What a flood zone means for a buyer
Out toward South Fork Estates, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. New construction in a floodplain near Hebbronville often needs a floodplain permit; call the permitting office early.
Places you'll see on the map
Hebbronville is the county seat, home to the main records offices. Smaller places on the map include Guerra, Las Lomitas, South Fork Estates, and Thompsonville. Around 4,720 people live in Jim Hogg County (Census estimate, 2023) across some 1,136 square miles. Jim Hogg County dates to 1913, so old deeds can run back a long way.
Low spots and local drainage
Small streams around Agua Nueva aren't always studied in detail, so walk the land after rain. Wetlands near Agua Nueva can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
How land is described here
Older tracts around Guerra are often described by metes and bounds, a series of courses and distances from a starting point. Subdivision lots in Las Lomitas usually use lot and block from a recorded plat instead, making them easier to find. Copy the legal description from the record for the parcel near Thompsonville for any title or survey request.

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.
