A developer who buys ground in Cedar Hill is buying a drainage plan before a building, because water decides what a pad can carry. We take on the grading, detention and storm work that makes a site buildable, and then the footings, slabs and paving that sit on top of it. We schedule, supervise and inspect the excavation, utility and concrete trade partners so one sequence runs from stripping to the final cure.
The industrial side of the city is moving along US-67. Hillwood Investment Properties is developing High Point 67 on more than 180 acres, with room to reach two million square feet, and an April 15, 2022 article reported that Pratt Industries would put over $200 million into a one million square foot building there, off US-67 below Mount Lebanon Road, with 150 full-time jobs. Large roofs on that scale shed a great deal of water, and every acre of roof and truck court needs a place to send it.
Underneath the grading sits the second question, which is the soil. Moisture under a slab is what moves a floor over time, and in Cedar Hill the clay does not hold still.
Services that belong in the same Cedar Hill sequence
Grading rarely travels alone. A detention basin needs pond and basin excavation, outlet structures and a clean spillway, and the pipes feeding it come from storm drain installation that has to be laid to grade before pavement is placed. When the plan calls for hauling spoil or importing select fill, we price import, export and haul-off as part of the same earthwork package.
On the concrete side, building pads, truck courts and dock aprons and parking fields all depend on how well the grading was finished. We bring those scopes together so the pad is not handed over to a paving contractor who inherits a surface that holds a puddle. One schedule and one set of survey checks keep the slopes honest from rough grade to joint layout.
Grading, basins and building pads for a Cedar Hill site
A typical scope starts with clearing, topsoil stripping and a stormwater pollution prevention plan, followed by mass grading to the elevations on the civil drawings. Cuts and fills are balanced where the site allows, and we track the haul so the owner is not paying twice for dirt that already sits on the property. Detention areas are cut to the designed volume, then shaped and protected until the vegetation takes.
Once rough grade is accepted, we move to fine grading, building pad preparation and the pipe and structure work inside the site. Slabs, flatwork and curbs follow in the order the buildings need them. Nothing is poured until the subgrade has been checked for density and moisture, and the survey confirms that drainage flows where the plans say it should.
Plan review, drainage approvals and inspections
The city reviews grading and drainage plans before a permit is issued, and the stormwater control measures on a site are inspected as work proceeds. We confirm early what each reviewer needs, such as the grading plan, erosion control layout and detention calculations, so the permit does not hold up mobilization. Drainage changes made in the field are documented and returned to the engineer before they are built.
Special inspections for concrete, compaction testing and reinforcement checks are placed on the calendar with the general contractor. We keep a record by pour and by lift of fill, and we hand the owner a closeout set that matches what was actually built, since a detention basin that differs from its permit is a problem no one wants to find later.
Soil report first, cure last, with water in between
We start with the geotechnical report and end with the cure, and in Cedar Hill the middle is about moisture. The area rests on an Austin chalk limestone uplift capped with gumbo clay that may be only a few inches deep in one spot and many feet deep a short distance away. The lower Lake Ridge side near Joe Pool Lake sits on Eagle Ford shale instead. That variation means a single boring does not describe a whole pad.
Where the clay is deep, we plan for over-excavation and recompaction or lime and cement soil treatment and keep the subgrade at a steady moisture until the slab is placed. A wetted, then dried and cracked, clay pad is not a floor base. We protect the surface from rain and traffic, and we check it again on the morning of the pour.
Open excavations, basins and moving equipment
Detention basins and deep trenches are the highest-risk work on a Cedar Hill grading job. We require trench protection and competent-person inspections for excavations, keep spoil piles back from the edge and mark every open cut with barriers. Equipment operators work to a traffic plan that separates haul trucks from people on foot, and flaggers control access where trucks cross public streets.
Stormwater controls are part of safety too. Silt fence, inlet protection and stabilized entrances keep mud off the road and out of the creek, and we inspect them after every significant rain. Trade partners attend a site orientation, and our supervisor walks the work daily to correct problems while they are small.
Who we build for around High Point 67 and beyond
Most of our Cedar Hill work serves logistics and warehouse developers who need pads graded and drained on a short schedule, and commercial developers bringing retail and office parcels out of raw land. Both want a single point of contact who understands that earthwork and concrete are one critical path. Industrial owners expect truck courts that drain away from dock doors.
Public owners also buy this work, since road, parks and drainage improvements share the same soils. We coordinate with their engineers on inspection and testing, and we provide the documentation public clients expect for payment and closeout. The same approach carries to projects in Grand Prairie and Arlington, where the clay and the drainage questions look familiar.
Joe Pool Lake, the state park and the shape of local ground
Joe Pool Lake was impounded in 1986 and covers 6,469 acres, with Cedar Hill State Park taking up 1,826 acres at its northeast corner. Land near the water changes how we drain a site, because outfalls, setbacks and erosion controls all have to respect a protected shoreline. Buyers along that edge want grading that keeps sediment out of the lake from the first day.
Up on the ridge the ground runs higher and drier, and the earthwork is more about shaping slopes than managing a high water table. Knowing which part of the city a site falls in lets us price rock, clay and drainage realistically before the first bid goes out.

Common Questions
Why does a Cedar Hill pad need a drainage plan before a slab design?
The slope of the pad, the location of inlets and the size of the detention basin set finished floor and paving elevations. If those are not fixed first, slabs end up too low or too flat. We review the civil drawings with the engineer before we price the foundation.
How do you handle gumbo clay under a building?
We read the geotechnical report, compare it with test pits, and then choose treatment such as lime or cement stabilization or removing and replacing the clay with engineered fill. The goal is a subgrade whose moisture stays steady until the slab is poured and cured. We recheck it before each pour.
Can you build the detention basin and the building pad together?
Yes. Cutting the basin supplies fill for the pad on many sites, so the earthwork is planned as one balance. We sequence the outlet structure, pipes and grading so the basin works before the pavement is placed.
Who inspects the work on a site near Joe Pool Lake?
The city reviews grading and stormwater controls, and independent testing firms check compaction and concrete. We place each inspection on the schedule and keep the records by pour and by lift of fill.
What do you need to give a firm price on a Cedar Hill site?
Send the civil drawings, the geotechnical report and the target schedule. With those we can quote grading, drainage and concrete as one scope and identify where extra borings or soil treatment might be needed.
