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 has fallen 18.9% since 2010. Thin comparable-sales data is the practical problem: fewer transactions means wider valuation uncertainty, and services like public water or broadband may be contracting rather than expanding. Verify that any utility a listing promises is actually still being extended.
TerraIQs carries 2,986 scored parcels across Glasscock County's 900 square miles — about 3 per square mile. That profile is large working tracts rather than subdivided lots, so soil, water and legal access carry most of the value.
Flood risk in Glasscock County
Our current FEMA extract shows no mapped Special Flood Hazard Areas in Glasscock County. Read that precisely: it means detailed DFIRM flood mapping has not been published for this area, which is common in sparsely populated counties — it is not a finding that the land doesn't flood. For an unmapped county a report leans on terrain and slope analysis instead, and a local floodplain administrator is worth a call.

Contamination and environmental records
No known contamination sites are recorded in Glasscock County in our source layers (EPA Superfund and state brownfields). That is a clean result for the datasets we carry, but these layers only cover reported sites — an unrecorded former dip vat, fuel tank or dump won't appear in any public layer.

What due diligence in Glasscock 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 Glasscock County specifically, note that pipeline crossings are common across Texas and are invisible from the road — pipeline easements restrict where you can build permanently.
Frequently asked
TerraIQs carries 2,986 scored parcels in Glasscock County. Statewide the dataset covers 14.3M+ parcels across all 254 counties; the scored subset is the rural-shard parcels, while urban and residential lots have full dossiers without a quality score.
Our current FEMA extract shows no mapped Special Flood Hazard Areas in Glasscock County, which means detailed DFIRM mapping has not been published there — not that the land doesn't flood. A parcel report falls back to terrain and slope analysis.
Flood zones, pipeline and utility proximity, contamination site distance, water well records, NRCS soil and septic suitability, slope and terrain, zoning where it exists, infrastructure, protected areas, critical habitat, road access with traffic counts, and population growth context — each with its source dataset version and retrieval date.
