Thinking about a house near Dilley? A quick look at the Pearsall flood zone map shows whether it sits in a FEMA flood zone, and no account is needed. Covered here for Pearsall: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Frio County parcel viewer.
The Pearsall flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: type an address near Dilley, then open the map view for that panel. Rural land near Dilley with no street number can still be found: search the nearest road and click inside the land.
Pulling up a parcel
Your first stop is the Frio County parcel viewer; it maps every assessed parcel from Bigfoot to Dilley. For property near Bigfoot, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. On ground around Dilley, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Low spots and local drainage
Creeks and ditches near Bigfoot may not have detailed mapping, so walk the land after rain. Wetlands near Dilley can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Places you'll see on the map
Pearsall serves as the county seat, which is where the courthouse records live. You'll also find Dilley and Bigfoot, each with its own cluster of lots. Around 17,987 people call Frio County home (Census estimate, 2023) spread over some 1,134 square miles. Frio County was organized in 1871, which matters when you trace an old farm's title.
City limits and county records
Pearsall is part of Frio County, Texas, and the county assessor maps its lots. Pearsall is also the county seat, which puts the County Clerk close by. In and around Dilley, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the town limits near Dilley generally falls under county rules rather than the town's.
When a parcel crosses a boundary
Frio County meets Atascosa County, Dimmit County, La Salle County, Medina County, and Uvalde County, all with their own assessor records. Acreage along the edge near Bigfoot can show up across two assessors' files, so look at the adjacent map before you assume the acreage. For property near Dilley, the Platbookmapper state page lists every bordering county map across Texas.
Decoding the flood zone labels
Closer to Dilley, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For a home near Dilley, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
Backing up the map with records
For anything that matters, pull the recorded deed from the County Clerk; the parcel map near Bigfoot only summarizes it. For a home near Dilley, use the instrument number shown in the record panel to skip a name search.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the Frio County parcel viewer too to see exactly which lot near Dilley you're looking at.
What a flood zone means for a buyer
On ground around Dilley, ask for an Elevation Certificate: it compares the building to the BFE. Building or adding on near Dilley in a mapped zone usually means extra permit review; call the permitting office before you plan.
A short flood checklist
Request whether the home has flooded on the property near Dilley; getting a quote early avoids surprises.
What the map can't tell you
Acreage on the record is a tax-roll number; only a licensed surveyor establishes the real boundary on land around Dilley. With a lot near Dilley, owner names and values update on a schedule, so a deed recorded last month might lag behind.
How land is described here
Rural deeds near Dilley commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Platted lots around Dilley refer to a recorded plat, making them easier to find. Keep the legal description for land near Dilley when you talk to a surveyor.

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.
