What the numbers mean for a buyer
Population is up 21.3% 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 32,437 scored parcels across Tarrant County's 865 square miles — about 37 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 Tarrant County
Tarrant County has 6,467 mapped Special Flood Hazard Area polygons — extensive, well-studied flood mapping. At this density the question is rarely whether flood zones are nearby but which part of a given parcel sits in one: a parcel can be half Zone AE and half Zone X, which changes both the insurance requirement and where you can actually build.

Contamination and environmental records
There are 61 recorded contamination sites in Tarrant County — a high count that reflects industrial history. Proximity is the thing to quantify: a report measures the distance from your parcel to each site, because a plume's relevance depends on distance, groundwater direction, and whether you intend to drill a water well.

What due diligence in Tarrant 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 Tarrant 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 32,437 scored parcels in Tarrant 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.
Tarrant County has 6,467 mapped Special Flood Hazard Area polygons. Whether a specific parcel is affected depends on drainage rather than property lines, so it needs a parcel-level check — a single parcel can span both Zone AE and Zone X.
