Rain on a master-planned community has to be collected, slowed and released without flooding the streets or the foundations, so grading and drainage come first when we plan work in Heartland. We shape pads, build detention areas, set inlets and pipe and then place the slabs, walks and paving that depend on the finished grades. The goal is a site that drains from the first storm and keeps its slabs dry.
Heartland is a community of about 2,000 acres roughly 25 miles east of Downtown Dallas, and four of the five schools planned there sit within its boundaries. That mix of homes and campuses means grading plans have to serve streets, lots, parks and school sites at once, with shared ponds and channels. We read the civil plans for the whole development so a pad we pour fits the system around it.
Growth is steady and school-driven. The 2020 census counted 8,509 residents in the community, which Crandall Independent School District serves. Voters in that district approved a $365 million bond on May 7, 2022 that pays for a new middle school, a transportation building, a career and technical or STEM facility, an addition to the high school and a pair of elementary campuses. An earlier $125 million bond from May 2017 expanded the high school to 1,550 students and planned a second middle school for 1,600 to 1,800 students, at about $48.3 million. We schedule, coordinate, supervise and inspect the trade partners who carry out the earthwork, pipe and concrete for these kinds of owners.
Buildings that depend on a dry site
School buildings are the most visible example: classrooms, gyms, cafeterias and bus lanes, all slab-on-grade, all sensitive to moisture under the floor. Retail pads, clinics, child care centers and amenity buildings for homeowner associations are also common in a community of this kind.
Each building has a finished floor elevation set against the drainage plan, and we survey that elevation before the footings are poured. A floor a few inches too low can flood in a heavy rain, and a floor too high can cause awkward ramps and steps at every door.
Athletic fields and play areas next to the building need their own drainage. We coordinate sub-drains, inlets and swales with the field contractor so water leaves the grass without undercutting the paved edges around it.
Working around homes, buses and buried pipe
A site beside occupied homes and school routes needs careful controls. We fence work areas, post signs, use flaggers where trucks enter and keep streets clean. Open excavations and detention basins are barricaded, since children and pets find them quickly.
Trenches are sloped or shored, and a competent person inspects them every day and after rain. Hot-weather pours get shade, water and rest breaks for finishers, and we begin early in summer to avoid the worst of the heat.
Neighbors deserve notice, too. Before a large pour or a night-time delivery, we tell the district or the association, so residents are not surprised by trucks or pumps on their street.
Grading, ponds, pipe and slabs
A drainage package includes clearing, stripping, mass grading, fine grading, storm drain installation, inlets, outfalls and detention and retention ponds, followed by slab and paving work that follows the finished grades. We survey at each stage so a late correction does not touch finished concrete.
For subgrade moisture, we use proof rolling, lime or select fill where the report calls for it and compacted base to give uniform support under slabs. Moisture control continues through curing, since a slab that dries from the top only will curl at the edges. Erosion control is installed before the first scrape and maintained until the site is stabilized.
Drainage and erosion reviews
Drainage plans, detention sizing and erosion control are reviewed by the city or county and, for school sites, by the district's engineer. Stormwater permits require inspection logs and repairs after storms, and we keep those logs with the project file.
Slab work adds reinforcement checks, concrete testing and special inspections. We notify inspectors ahead of each placement, hold the pour if one is missing and compile the reports into a closeout set for the owner.
Because the development has several owners, a pond built for one phase may serve another. We confirm capacity and outfall with the engineer of record before we close any basin, so a later builder finds a working system.
Matching the school calendar
A campus opens on a fixed date, so the schedule is built backward from it: grading, utilities, foundations, framing, roofing and finishes, with each hold point named. Concrete is rarely the longest task, but it is the one that every other trade waits for.
Rain delays are common in the spring, and we plan float for them. A pond or channel built in the wrong season can erode before grass takes hold, so we sequence stabilization with the weather as well as the calendar.
Concrete pours follow the same logic. We watch the forecast three days ahead, set pumps and trucks the evening before and call off a placement if a storm line is close. A pour that is rained on is worse than a pour that is moved.
Serving Kaufman County from the east side of the metro
Heartland is close to Forney, Mesquite and Balch Springs, which lets us stage equipment and ready-mix supply across the east side. Owners with several parcels, such as a developer or a district, can package work to cut mobilization costs.
Schools and healthcare owners get a dedicated project manager who understands the reporting required, and developers get cost breakdowns by phase. We check traffic and plant locations before setting pour times, and we keep a spare plant on call for larger placements. Early in the project we also confirm where each plant is, how long its trucks take to reach the site and what the cutoff time is for next-day orders.

Common Questions
How do you protect a slab from groundwater and surface water?
We set the finished floor above the surrounding grade as the plan requires, slope the ground away from the building, compact a uniform base and place a vapor barrier where specified. Gutters and downspouts discharge to pipes or splash blocks that carry water away from the footing.
What does a detention pond need during construction?
Erosion control around the basin, a stable outlet and a plan for sediment cleanout. We build it early so it can catch runoff while the rest of the site is under construction, and we clean it before final grading.
Can you work on a school site while students are nearby?
Yes, with fences, planned truck routes, noise control and a clear schedule. The principal or facility office gets the plan before we mobilize, and we adjust the routine as the school asks.
What if soil tests show expansive clay?
The engineer will specify treatment, which may include lime, select fill, deeper footings or a post-tensioned design. We build to that design and keep moisture steady during construction.
