Water leaves a site correctly only when the grading, the pipes and the basin were designed together and built to the same survey. In Kennedale we build drainage from the outfall backward: first confirm where the water is allowed to go, then size and shape the basin or channel that holds it, then set the pad and pavement elevations so every surface drains to a structure. That order prevents the common mistake of finishing a pad and then discovering it has nowhere to shed water.
Kennedale sits on State Highway 496 in southeastern Tarrant County, ten miles southeast of Fort Worth, according to the Handbook of Texas. The 2025 estimate is 10,626 residents, compared with 8,517 counted in 2020. A town that has grown that quickly turns pasture into rooftops and pavement, and each acre of new impervious surface needs a plan for the extra runoff.
We schedule, coordinate, supervise and inspect the earthwork, pipe and concrete trade partners so the grading plan, the detention volume and the pavement elevations stay in agreement from first stake to final stabilization.
Excavation, slopes and open basins
Detention basins and channels mean deep, open excavations with sloped sides, standing water in wet weather and heavy equipment working near the edge. We set slope limits by soil type, keep spoil piles back from the edge and fence or mark open basins at night. Equipment operators work from a plan that shows overhead lines and buried utilities.
Wet weather raises the risk. Slopes that were stable in dry soil may slump after rain, so we inspect them after storms and before work resumes. Pumps, hoses and dewatering equipment are staged where they do not create trip hazards.
Close to Arlington, Mansfield and Burleson
Kennedale lies near Arlington, Mansfield and Burleson, so the material yards, haul routes and testing labs we use elsewhere in the area cover it. Short hauls help with earthwork, where trucking cost is a large part of the price.
A rail line has long been part of Kennedale: the Handbook of Texas records a Southern Pacific station and section house in the town. Rail corridors leave berms, ballast and utility crossings, so on any parcel near the old line we check easements and probe for fill.
Buildings that need a drained site
The sites we grade include light industrial and fabrication buildings, schools, offices and retail pads. Industrial buildings with truck yards need grading that keeps water off the dock and out of the trailer lot. Schools and offices need accessible routes and parking that drain without ice or ponding.
For manufacturing plants and flex and light industrial buildings, we also shape yard areas for outdoor storage and equipment, with base and drainage that tolerate heavy loads.
Soil, rain and the grading balance
Cut and fill should balance on most sites, because hauling dirt off and bringing it back costs more than moving it across the site. We calculate quantities from the survey, plan haul routes and stage stockpiles. If the soil is clay-rich, we also plan moisture conditioning so the fill can be compacted to density.
Rain is the main variable. A site that has been stripped and left open will erode, and a prepared pad that is soaked needs drying or lime. We schedule grading in sections, stabilize each as it is finished and keep silt fence and inlet protection maintained.
Employers that need yards and floors
The city's 2024 annual financial report names Sabre Industries (Fort Worth Tower) as the largest employer at 450 to 500 people, with Kennedale ISD next at 400 to 450. A large manufacturer needs outdoor storage, truck routes and heavy slabs, while a school district needs buildings, bus lanes and playgrounds, and both depend on good drainage to keep their grounds usable.
Other listed employers include steel, compounding and contracting businesses of fifty to one hundred workers each. Smaller industrial users like these often add yards or buildings in stages, and we plan grading so a later expansion can tie into the first phase without regrading what was already finished.
Moisture under buildings is the other link to drainage. A building pad that sits low or shares a swale with a parking lot can stay wet for weeks, and a wet clay subgrade swells and softens. We raise pads where the plan allows, drain the base to a daylight outlet and keep construction water away from the footprint so the subgrade is dry when the slab crew arrives.
Survey, shape, test, stabilize
We begin with the survey and the drainage report, set grade stakes to the design and build in lifts that are tested for density. Basins are cut to the volume and slopes the engineer specified, and outlet structures are set at the correct elevation before the embankment is closed.
We then stabilize. Seeding, blankets and rock lining go on soon after final grade, and we keep records of inspections and rain events so the owner can show the city the site was managed properly.
Owners who rely on dry, stable ground
Industrial and manufacturing owners, school districts and commercial developers are the usual owners. Each has different priorities: an industrial owner wants a durable yard, a district wants a safe campus and a developer wants an approved plan with the least land used for detention.
General contractors also bring us in to handle the grading and drainage package on a larger project, so the building trades do not inherit a poorly drained pad.
Drainage review and inspections
The city reviews drainage plans for runoff rates, outfalls and erosion control, and the reviewer may ask for calculations, easements and maintenance responsibility for the basin. We help the design team understand what the reviewer will look for, so permits are not delayed by missing information.
During construction, inspectors check erosion controls, pipe installation, outlet structures and final grading. We keep a checklist for each visit, take photographs and share the results, so the final acceptance has a clear record.
If the project disturbs a large area, the stormwater pollution prevention plan sets inspection intervals and record-keeping rules. We assign one person to walk the controls after every significant rain and write down what was repaired, so the file is complete if the site is audited.
Send us the Kennedale survey
Send the survey, the drainage report and your schedule for the Kennedale site. We will return a price that separates mass grading, basins, pipe and structures, and paving. If the pad needs special subgrade work, we can review over-excavation and recompaction with your engineer.
Common Questions
How do you decide between a detention pond and underground storage?
A pond is usually cheaper per cubic foot but uses land. Underground storage uses less land and costs more. The engineer decides based on the site, and we price both so the owner can compare.
What happens if the soil is too wet to compact?
We dry it by spreading and turning it, mix it with lime or cement, or replace it with select material. The engineer approves the method, and density tests confirm the result before we build on it.
Who maintains a detention basin after construction?
The owner usually does, under the terms of the approved plan. We give the owner an as-built survey and a list of the outlet structures and slopes to inspect after storms, so maintenance is straightforward.
Can you regrade an existing industrial yard that floods?
Yes. We survey the yard, identify where water collects, and propose new slopes, inlets or channels. Work can be done in phases, leaving part of the yard in use while another is rebuilt.
