Water has few places to go in a compact, flat city, and a site that does not drain will ruin a slab as surely as a bad mix. In Jacinto City we grade, shape and drain commercial and industrial sites so rain leaves the pad and the parking field without standing near the building, and we finish the inlets, swales and detention features in concrete that holds its slope.
The city covers about 1.9 square miles of land at an elevation of about 30 feet, in central Harris County. With that little relief, every tenth of a foot of fall counts, and a small survey error becomes a puddle at a loading door. We set grade stakes from the civil plans, check them against the as-built surface and correct problems before paving, not after.
We schedule, supervise and inspect the earthwork, pipe and concrete partners, and we keep one set of survey and test records for the owner. Subgrade moisture is the other half of the story, and we cover it in the sections below.
Sites where drainage decides the design
Several kinds of sites in the city live or die by grading. A retail shopping center needs a parking field with a slope sufficient to carry water to inlets without a trip hazard at the sidewalk, and a flex or light industrial building needs a dock apron that falls away from the doors.
Office and service buildings are less demanding but just as sensitive to ponding at entries. We review the civil plan with the architect, mark the drainage divides and tell the owner early if the proposed finished floor is too low for the site.
Redevelopment lots deserve a closer look. A paved lot that is rebuilt with more impervious area sheds more water than the old one did, and the reviewing office may require storage that the original owner never provided. We raise that possibility at the first meeting, size a basin or underground option with the engineer and show its cost beside the paving, so the budget is complete before the lease or loan is signed.
Owners and contractors we work for
The primary buyers are commercial developers and owners of small industrial properties who want a finished pad with clear acceptance numbers. They need a contractor who can give a price on grading, storm structures and paving in one proposal.
General contractors also bring us in for the site package behind a building. They want a single schedule, test reports in the format they need for closeout and a partner who answers calls. We provide a pour calendar and weekly progress notes.
Keeping a tight city site safe
Small parcels leave little room for equipment, so we plan the site layout before mobilization: a controlled entrance, a marked haul route, a laydown area and a washout. Neighbors are close, so we manage dust with water and sweeping, and we keep mud off the street.
Open excavations get a daily inspection and a barricade, and detention basins are fenced or sloped to a safe angle until they are finished. Daily logs record weather, headcount and the inspections performed, and we correct any condition that could harm a worker or a passerby.
Grade first, then pour
We begin with the survey and the geotechnical report. From those two documents we plan stripping, cut and fill, proof rolling and compaction, and we decide where the site needs moisture conditioning or treatment. The pour only starts when the subgrade is firm, true to grade and checked by the owner's testing agency.
Throughout the work we keep a running survey of the surface. If a rain event moves silt or softens the base, we regrade and retest before the next phase. That discipline is why our drainage structures meet the design elevations and our slabs lie flat.
Permits, drainage review and testing
Grading and drainage work normally needs a permit, and the local building department or city engineer reviews the plans for runoff, detention and erosion control. We prepare the stormwater pollution prevention plan, install silt fence and inlet protection and keep inspection logs as the permit requires.
Testing is part of every phase. Compaction tests confirm the fill, concrete cylinders confirm the strength, and a final survey confirms that the finished grade matches the plan. We keep the reports organized for the owner and the reviewing office.
Services that fit a drainage project
Grading usually comes with a short list of related scopes. Mass grading creates the pad and the surrounding slopes, while storm drain installation collects the water and carries it to the outfall. Where the site needs a basin to hold runoff, we excavate and finish it.
Concrete flatwork completes the system, and owners with sites in Houston, Channelview or Deer Park get the same coordination. The flatwork includes curb and gutter, inlet aprons, flumes and parking. A site that was graded by one firm and paved by another often has mismatched elevations, which is why we prefer to coordinate all of it.
Why subgrade moisture matters at this crossroads
Three major roads, U.S. Highway 90, Interstate 610 and Interstate 10, converge at Jacinto City in central Harris County, and a railroad line also crosses the city. That mix of freight and commuter traffic makes the area attractive for service and light industrial uses, and it also means that sites are often small, odd-shaped and surrounded by established development.
The community grew from a 1941 subdivision filled with shipyard workers and employees of nearby steel mills and war plants, and it still functions as a bedroom community for local industry. For a builder, that history means older lots, older utilities and clay that has dried and wetted repeatedly. Controlling moisture under a new slab is the key to keeping it level.

Common Questions
How do you control moisture in the soil beneath a new slab?
We follow the geotechnical report, which may call for moisture conditioning, lime treatment or select fill. We also grade the site so water leaves the pad, and we place a vapor retarder under the slab. The testing agency verifies each step before concrete is placed.
Can you correct a site that already ponds?
Often, yes. We survey the surface, find the low areas and decide whether regrading, new inlets or a small detention feature will fix it. In some cases the answer is a concrete flume or a revised slope at the pavement edge.
What does a stormwater permit involve?
The reviewing office checks the drainage plan, and we install erosion controls such as silt fence and inlet protection. We keep inspection logs and make corrections the inspector requests.
Do you handle both grading and concrete on small parcels?
We coordinate both under one schedule. Having the same team plan grading and paving means the elevations match, and the owner has one point of contact.
How do you schedule work on a crowded site?
We plan entrances, laydown and haul routes first, then sequence earthwork, pipe and concrete so partners do not block one another. A weekly update keeps the owner informed.
