Land Grading Services That Drain Right and Clear Review
Water goes where you grade it, whether the plan intended it or not. Magrym delivers land grading services and drainage design across Midland and the Permian Basin, engineered to move water correctly, balance the earthwork, and meet the stormwater requirements for approval.
Site Grading and the Design That Decides Where the Water Goes
Grading and drainage design shapes the ground so the site drains the way it should. It sets the elevations, the slopes, the swales, and the stormwater features that carry water off the pads and away from the buildings. Done right, the site stays dry and passes review. Done wrong, water ponds where it should not and the problem shows up the first time it rains.
The cost of a grading plan is rarely the design. It is the fix. A drainage design that does not work in the field turns into a change order after the dirt is already moving. A plan that misses the stormwater requirement gets kicked back and loses weeks. Magrym engineers the site grading to drain correctly and to clear the reviewing authority the first time.
Because we survey the parcel and know the terrain, the grading starts from accurate existing conditions, not a guess at where the water sits today. Our licensed engineers deliver grading, drainage, and stormwater plans coordinated with the survey, so the design fits the real ground. You talk directly to the engineer on your project.
Grading and Drainage System Design, Start to Finish
We cover the grading and drainage system design your site needs, from the earthwork balance to the stormwater approval, built on real survey data.
Grading Plans
We set the finished grades, slopes, and pad elevations so the site drains, meets the access and ADA requirements, and works for the buildings on it.
- Finished grade and pad elevations
- Slope and access design
- Spot grades and contours
Drainage Design
We provide surface water drainage design, engineering the swales, inlets, and storm systems that collect the runoff and carry it off the site to the right outfall without flooding anything downstream.
- Swales and channels
- Inlets and storm sewer
- Outfall and downstream analysis
Stormwater and Detention
Our detention pond design work sizes the storage and water quality features that hold and release runoff at the allowable rate, the piece the reviewer looks for first.
- Detention pond sizing
- Release rate and outlet control
- Water quality features
Earthwork and Cut-Fill
Our earthworks design balances the cut and fill so the site moves as little dirt as possible, which controls the biggest cost driver on most grading jobs.
- Cut and fill optimization
- Earthwork quantities
- Balanced site design
Erosion and Sediment Control
We design the erosion and sediment control plan that keeps soil on the site during construction and satisfies the stormwater permit.
- Erosion and sediment plans
- Best management practices
- Stormwater permit support
Modeling and Review Support
We build the hydrologic and hydraulic models that back up the design, and we respond to the AHJ review so the drainage report gets accepted.
- Hydrologic and hydraulic modeling
- Drainage reports
- AHJ review responses
Who Relies on Our Grading and Drainage
Anyone shaping ground for construction needs a grading plan that drains correctly and satisfies the stormwater review.
Developers and Builders
Commercial and residential sites need grading and drainage that clears the stormwater review and drains right after it is built. We design to both, on real survey data.
General Contractors
Contractors need a grading plan that balances the earthwork and can actually be built. We optimize cut and fill so the dirt work is efficient and the plan holds up in the field.
Energy and Industrial
Pads, laydown yards, and facility sites across the Permian Basin need grading and drainage that handles the terrain and the runoff. We know this ground and the storms.
Municipalities and Public
Public and institutional projects carry strict drainage criteria. We deliver the grading, drainage, and detention design and the reports these projects require.
Real Survey Data From Your Drainage Engineer
Drainage design fails when it starts from bad topography. Magrym is the Midland firm that surveys the site and engineers the grading, so the plan reflects the real ground and one firm stays accountable from the topo to the approved plan, with the same drainage engineer involved throughout.

- Headquartered in Midland, working West Texas every week
- In-house survey means accurate existing conditions
- You talk directly to the engineer on your job
- HUB and DBE certified, Minority-Owned
A clear path, run by the same engineer, built to drain right and clear review.
Survey and Scope
We survey the existing grade and confirm the drainage criteria for the jurisdiction, so the design starts from real conditions. You get a fixed-fee proposal up front.
Grading Concept
We set the pad and finished grades, balance the earthwork, and confirm the site drains before we detail the storm system.
We design the stormwater management system and detention, model the hydrology and hydraulics, and prepare the drainage report that supports the submittal.
Submit and Approve
We seal and submit the plans, respond to the AHJ review, and deliver an approved grading and drainage set the contractor can build to.
Frequently Asked Questions
Grading and drainage design is the civil engineering that shapes the ground so a site drains correctly. It sets the finished grades, slopes, and pad elevations, and designs the swales, storm sewer, and detention that carry runoff off the site at the allowable rate. The plans have to drain the site and satisfy the stormwater requirements of the reviewing authority.
Developing a site adds pavement and roofs, which increases runoff. Cities and counties require a drainage study, and usually detention, to make sure the developed site does not send more water downstream than the undeveloped land did. Detention holds the extra runoff and releases it slowly. It is one of the first things a reviewer checks.
Earthwork is often the biggest cost in site construction, and grading design drives it. A plan that balances cut and fill moves less dirt and does not haul material on or off site, which saves real money. We optimize the cut and fill in the grading design so the earthwork is as efficient as the site allows.
The common reasons are a drainage study that does not meet the detention or release-rate requirement, runoff that is directed onto a neighbor without an easement, or an erosion control plan that is missing or incomplete. We design to the jurisdiction’s criteria and prepare the supporting report so the submittal clears review the first time.
Yes. We survey the existing grade with our own crews, so the grading design is built on accurate topography rather than an old or incomplete survey. Drainage design is very sensitive to the existing grade, and starting from good survey data is the single most reliable way to avoid a design that does not work in the field.
Yes. Our civil engineer drainage work is part of the civil engineering we provide alongside land surveying and construction services. The same firm can survey the parcel, design the site and the grading, stake it for construction, and test the compaction, which keeps the whole project coordinated on one set of data.
