Population from U.S. Census ACS 5-year tract estimates aggregated to county · flood from FEMA NFHL · contamination from EPA Superfund and state brownfields · generated 2026-10-07.
What the numbers mean for a buyer
Population is up 36.2% since 2010 — steady growth rather than a boom. Ag-exemption rollback is the thing buyers most often miss in these counties: land that has carried an agricultural valuation for years can trigger several years of back taxes when the use changes.
TerraIQs carries 47,282 scored parcels across Bastrop County's 888 square miles — about 53 per square mile. That profile is a mix of subdivided tracts and working acreage — the county where both urban and rural constraints show up in the same search.

What due diligence in Bastrop County involves
The county-level numbers above tell you what to expect; they don't settle any individual parcel. The checks that decide a deal — legal access, title exceptions, mineral severance, septic suitability, agricultural valuation rollback — are parcel-specific and partly document-based. Our Texas land due diligence checklist walks the full sequence in the order we'd run it, including which steps are free and which are worth paying for.
In Bastrop County specifically, note that pipeline crossings are common across Texas and are invisible from the road — pipeline easements restrict where you can build permanently.
