Ahead of any purchase around Elgin, pull up the Bastrop flood map: the zone on that map shapes insurance, building rules and resale. What this Bastrop guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and matching it with the county parcel viewer.
Getting started with the Bastrop flood map
Start with FEMA's Flood Map Service Center: type an address near Mustang Ridge, and choose the dynamic map. Vacant ground around Smithville is still easy to locate: zoom in from US Route 290 and click inside the land.
The free map to start with
Go first to the Bastrop County parcel viewer; it covers every tax parcel around Smithville and Mustang Ridge. In and around Smithville, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Elgin, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Bastrop, TX: the basics
Bastrop lies within Bastrop County, Texas, so its parcels are on the county's map. Bastrop is also the county seat, so deeds and plats are filed in town. For land near Smithville, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the city limits toward Elgin often answers to county rules, not municipal ones.
Bastrop County in a few facts
Bastrop serves as the county seat, which is where the courthouse records live. You'll also find Smithville, Elgin, and Mustang Ridge, where town lots give way to larger tracts. Around 110,778 people call Bastrop County home (Census estimate, 2023) on roughly 888 square miles. The county dates to 1837, and some chains of title near Mustang Ridge are long.
Beyond the mapped zones
Small streams around Elgin aren't always studied in detail, so walk the land after rain. Wetlands near Elgin can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Mustang Ridge are kept by the County Clerk. For property near Smithville, have ready the book and page from the tax record to skip a name search.
What the zone letters mean
An AE label comes with a base flood elevation, which plain A zones lack; builders around Mustang Ridge design to it. With a lot near Elgin, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.

Which office to call
Questions about value or the owner field for land near Elgin belong with the appraisal district, which maintains the tax roll. Building or septic questions for a lot near Smithville are for the local planning and health departments, depending on whether the land is inside town limits.
What to request from a seller
Ask the listing agent whether the home has flooded for the house near Elgin; getting a quote early avoids surprises.
Reading the legal description

Platted lots around Smithville usually use lot and block from a recorded plat instead, which is simpler to follow. Keep the legal description for land near Smithville for any title or survey request.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so pair it with the Bastrop County parcel viewer to confirm you have the right parcel near Smithville.
Lenders and permits
For acreage around Smithville, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. Remodeling a house in a zone near Elgin often needs a floodplain permit; check with the county or town building office early.
