Denton County sits in the Cross Timbers and Grand Prairie region, sandy loam over sandstone in the timbers and shallow soils over limestone on the prairie, which drain better but still move with the seasons. Use the bid checklist to compare, then request one written quote.
Two kinds of ground in one county
Denton County straddles the Blackland Prairie on its east side and the Eastern Cross Timbers through its middle, so a bid for a lot in Little Elm or The Colony may face different soil than one in Argyle or Ponder. A bidder who has walked the lot and names the base depth for that ground is ahead of one who quotes one base for everything.
County permits outside the cities
Outside Denton, Lewisville, Flower Mound and the other cities, the county's development permit applies to any improvement, and the application wants a site plan with distances to at least two property lines. For a shop slab or an RV pad on acreage, that site plan is the same drawing you should be getting from the bidder anyway; ask for it as part of the bid.
What Cross Timbers and Grand Prairie ground means for the bid
Denton County is Cross Timbers and Grand Prairie country: sandy loam over sandstone in the timbers and shallow soils over limestone on the prairie, which drain better but still move with the seasons. The practical reading for a bid is that the base and drainage lines are not optional. Ask what is removed, what is placed and compacted, how thick the slab is at the edge, and where the water goes.

- Denton County requires a development permit for any improvement to a property in its jurisdiction, applied for online through Civic Access or at Development Services, 3900 Morse Street in Denton; the application needs a site plan showing proposed improvements and their distances from at least two property lines. source
- Since January 1, 2008 the Denton Central Appraisal District's boundaries match the county's; value, exemption and protest questions go to the appraisal district, not the county. source
- The Eastern Cross Timbers run from the Red River through eastern Denton County and along the Dallas–Tarrant line, and Texas Parks & Wildlife notes the east Cross Timbers soils are slightly acidic sandy or sandy loam, while the county's eastern edge is Blackland clay, so soil can differ from one subdivision to the next. source
