Weighing a property around Nixon? A quick look at the Floresville flood zone map shows whether it sits in a FEMA flood zone, and the lookup is free. Covered here for Floresville: finding the address on FEMA's map, reading the zone codes, and pairing it with the Texas county CAD map.
The Floresville flood zone map: start here
Start with FEMA's Flood Map Service Center: search an address around Elmendorf, then open the map view for that panel. Vacant ground around La Vernia is still easy to locate: zoom in from US Route 181 then click the parcel area.
Getting to the right map
Your first stop is the Texas county CAD map; it maps every assessed parcel around Nixon and Elmendorf. Without an address in hand, follow US Route 181 on the aerial until the lines appear, then click inside the one you want. For a tract near La Vernia, the parcel card typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
A short flood checklist
Ask the listing agent whether the home has flooded for the house near Stockdale; an insurance quote early keeps the budget honest.
Floresville and the county around it
Floresville sits in Wilson County, Texas, and the county assessor maps its lots. As the county seat, Floresville hosts the courthouse, handy when you need recorded documents. In and around Elmendorf, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the city limits near Elmendorf usually follows county rules, not municipal ones.
Zones on the Floresville flood zone map
An AE label includes a base flood elevation (BFE), which plain A zones lack; builders around Nixon design to it. Closer to La Vernia, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Beyond the mapped zones
Creeks and ditches near Elmendorf may not have detailed mapping, so ask neighbors about past flooding. Wetlands near La Vernia can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near La Vernia, so load it before you lose signal. A saved image of the lot near Poth and its lines is a good backup.
Wilson County in a few facts
Floresville is the county seat, where most land records are kept. You'll also find Poth, Elmendorf, Stockdale, and La Vernia, where town lots give way to larger tracts. Around 54,183 people call Wilson County home (Census estimate, 2023) on roughly 804 square miles. Wilson County dates to 1860, and some chains of title near Stockdale are long.
Recorded documents worth pulling
For anything that matters, request the recorded deed from the County Clerk; the parcel map near Poth only summarizes it. Inherited tracts around Stockdale may trace back through a long string of deeds, and a title company is worth hiring before a purchase.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so open the Texas county CAD map next for the outline of the tract near Elmendorf.
Limits of the parcel data
Listed acreage is an assessed number; only a licensed surveyor establishes the real lines for a parcel near Elmendorf. If the land is near Elmendorf, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Next door to Wilson County
Wilson County meets Atascosa County, Bexar County, Gonzales County, Guadalupe County, and Karnes County; every one of them runs a separate parcel map. Ground near La Vernia that runs to the line can be split across two assessors' files, so open the neighboring map before you assume the acreage. On ground around La Vernia, the Platbookmapper state page links each bordering county map for Texas.
Money questions tied to the zone
For a home near Nixon, get the Elevation Certificate if one exists: it can change the insurance price a lot. Remodeling a house in a zone near La Vernia often needs a floodplain permit; call the permitting office early.
