Mass Grading and Earthwork in Amarillo and the Panhandle

The first stage of a $253 million beef plant in Amarillo needed no building permit. According to a trade report from August 2025, the city issued the permit only after the site work was done, and everything before it was dirt work. That detail is worth knowing if you are planning a large parcel on the high plains. Grading is the one trade that can start moving money into the ground before the permit office has seen a drawing, which makes it the trade where good planning pays back fastest.

Mass grading is the cut, fill, compaction and shaping that turns a raw tract into a buildable pad, a truck court or a parking field. In the Panhandle it is also where the soil, the wind and the drought show up first. The ground can be hard caliche one week and a sticky clay the next, and the surface can leave the site as dust if nobody is watching the water truck.

We grade commercial, industrial and institutional sites across Potter and Randall counties and out into the Panhandle. This page covers how we read a site before we price it, what drives the number, how we sequence the work around weather and what the drawings should say before the first scraper starts.

Two soils shape most of the grading we see around Amarillo. The first is the Pullman series, a clay with 35 to 50 percent silicate clay, slow permeability and vertic properties. USDA describes cracks at least 5 millimeters wide reaching down about 84 centimeters, which tells you the ground swells when wet and opens when dry. A pad built on that clay without moisture control will move, and the movement shows up later as floor cracks and door frames that stop closing. The cure is a moisture plan for the pad that the foundation design assumes.

The second is the shallow caliche layer found on the Southern High Plains. The Kimberson series puts an indurated, fractured, platy caliche layer 4 to 20 inches below the surface. Cutting through it takes a ripper, a heavy dozer or sometimes a hydraulic hammer, and the excavated rock does not make fill that compacts like clean soil. We ask for borings before we commit to a cut and fill balance, because the balance on paper often changes once the caliche is found.

Earthwork pricing in this market turns on haul distance, rock, water and moisture. A balanced site, where cut roughly equals fill, is the cheapest to build. An import site needs trucks and a borrow source, and the nearest approved material may be a long haul on a plains county road. An export site needs a place to put surplus soil, which is not always free.

Water is its own line item. Dust control and moisture conditioning both depend on a source, a truck and a plan for when the supply is short. In May 2022 nearly all of the Texas Panhandle was in extreme drought and as much as 97 percent of topsoil was rated very short of moisture, according to USDA crop figures reported at the time. In a year like that, bringing clay to optimum moisture can cost real money. We carry water in the number and show it as its own line so you can see what it takes to compact in a dry year. Logistics and distribution owners with long, flat pads feel this most, because they buy the most acres of compacted fill.

Our mass grading scope covers clearing, stripping, topsoil handling, cut and fill, proof rolling, subgrade preparation, lime or cement stabilization where the geotechnical report calls for it, and fine grading to the tolerance a slab or paving contractor needs. We also build the temporary measures that go with it: construction entrances, silt fence, inlet protection and a perimeter berm that keeps stormwater from walking off the job.

The finished surface has to drain. The City of Amarillo residential code asks for lot grading that falls 6 inches within the first 10 feet away from a foundation. Commercial sites follow the engineer of record, but the idea carries over: water has to leave the building edge fast. Where the grade feeds a basin or a playa edge, we coordinate the work with stormwater and drainage construction so the pad, the inlets and the outfall are built to the same elevations. Paved areas follow the same grades, and our parking lot construction picks up where the rough grade ends. For roads, utilities and lots in one package, our site development and utilities work covers the full sequence.

Grading schedules in the Panhandle are weather schedules. Wet clay stops compaction, so a stretch of rain can cost a week. Hard freeze stops it too, and a thaw leaves a soft crust. Summer wind dries the surface quickly, which helps for a day and then turns into a dust problem. We build float into the earthwork schedule rather than hiding it in the later trades.

The best use of that float is to start early. Because dirt work can begin before the building permit, an owner who has the plat and the drainage approval in hand can have the pad rough graded while the permit drawings are still in review. That works well for logistics land such as the acreage near CenterPort Business Park and for large industrial pads for warehouse buildings, where the grading is the longest single task before the steel. We confirm with the city what counts as permitted work on each parcel before we mobilize.

Wind and dust are safety issues here, not just housekeeping. The National Weather Service recorded a record 83 mph gust at the Amarillo airport on March 14, 2025, with blowing dust cutting visibility below a quarter mile and a multi-vehicle pileup south of Canyon. On a graded site next to a highway, bare soil is a hazard to everyone on the road. We stage water trucks, phase the stripped area so no more ground is open than we can control, and shut down earthmoving when the forecast shows gusts that make dust uncontrollable.

The USDA research lab at Bushland was set up in 1938 to address wind erosion on the Southern Great Plains, and the problem has not gone away. We use stabilized entrances, seeded or mulched slopes where the schedule allows, and haul routes that keep trucks out of public streets whenever possible. Pads near the interstate, such as those along the I-27 corridor, are the ones where this matters most. Crews working near live roads get flaggers and a written traffic plan, and heavy equipment operators work with spotters wherever people are on foot.

Give us the address, the survey and any boring logs. We will walk the ground, mark what looks hard, and return a grading outline with the water, haul and rock assumptions written out.

Can we start grading before the building permit is issued?

Often yes. On a large beef plant in Amarillo the early work was classed as dirt work that did not need a permit, and the building permit came later. Rules differ by jurisdiction and by parcel, so we confirm the rule with the city or county before moving a machine. Platting, floodplain and drainage approvals still apply.

What does caliche do to a grading budget?

It slows production and wears equipment. A hard layer a few inches below the surface calls for ripping or hammering, and broken caliche is often poor fill. We recommend borings across the pad footprint so the cut and fill estimate is based on what is actually there rather than a guess.

How do you control dust on a dry site?

We limit the stripped area, run water trucks on a schedule, stabilize haul roads and entrances, and stop work when winds are too high to hold the surface. On a record wind day like March 14, 2025, nothing holds, so the answer is to shut down and protect neighbors.

How much does grading cost per acre?

There is no honest single figure, because haul distance, rock, water and import or export all move it. We price from borings, a survey and a drawn pad elevation. A site that balances on its own and has soft soil costs far less than one that needs imported fill across a long haul.

Do you handle stabilization of clay subgrade?

Yes. Where the geotechnical report calls for lime or cement treatment, or a moisture conditioned and compacted layer, we build it and coordinate testing so the slab or paving crew gets a subgrade that meets the report.
