We take a Texas site from concept plan to approved plans and through construction. Grading, drainage, paving, access, and water and sewer service are designed by one team, so the sheets agree before they reach a reviewer.
Three stages
- Test the site. A concept site plan and an early read on access, drainage, utilities and the review path. This is where a detention pond, a driveway location or a sewer route can change what the site holds.
- Design and approvals. Sealed site and grading plans, a drainage study with sealed hydrology and hydraulic calculations, erosion control, paving and utility plans, and the driveway permits and trip generation letters the agencies ask for. We answer review comments until the plans are approved.
- Construction. Submittal review, contractor questions, site visits and as-built drawings. See construction administration.
Who reviews a Texas site
The city reviews plats, site plans and drainage inside its limits, and often plats in its extraterritorial jurisdiction (ETJ). The county reviews land outside them. TxDOT reviews any driveway onto a state highway. A site that disturbs one acre or more needs coverage under TCEQ’s construction stormwater general permit, TXR150000. Over the Edwards Aquifer, TCEQ must approve a protection plan under 30 TAC Chapter 213 before regulated work starts.
What others provide
We build the plans on the boundary and topographic survey and the geotechnical report, which come from those consultants. Architecture, structural and MEP engineering stay with the building team. We coordinate with each so the civil set matches their work.
When to call
Bring us in before you close, or before a concept plan is fixed. In Lindsay, we laid out a 48-lot subdivision with its detention pond, water line extension and sewer. Outside Texas, see civil engineering in Colorado, Florida and Arizona.
