Stabilized Parking Lots for Wyoming Industrial Sites

Snow decides how a Wyoming parking lot gets built. Gillette averages 55.7 inches of it a year, and the plows that clear it scrape, gouge and stack it on whatever edge is nearest. A lot designed for a mild climate lasts a few winters here. A lot designed for plows, freeze-thaw and heavy trucks lasts a lot longer.

We build stabilized parking lots for plants, shops, warehouses and offices. Some carry employee vehicles. Many carry loaded trucks, forklifts and service rigs that behave nothing like a passenger car. We size the pavement for the heaviest thing that will actually cross it, not the average vehicle on the traffic count.

Stabilized means the ground under the pavement is made to behave. We treat or replace weak subgrade, give every square foot of surface a path for water, and place base that stays dry through a spring thaw. Whether the finish is asphalt, concrete or an aggregate surface, the structure under it does the work.

What a plow season does to pavement

Laramie sits at about 7,165 feet and gets roughly 11 inches of precipitation and 48 inches of snowfall a year. That is a dry climate with a hard winter. Meltwater is the problem. It gets into cracks at noon and freezes at midnight, and each cycle opens the crack a little wider. Pavement edges, joints and low spots fail first.

Sun and wind help, but neither is a plan. On a large lot we decide where the snow goes before we decide where the cars go. Storage areas sized for a heavy winter and pushed away from drains and inlets prevent the April flood that undermines the pavement edge. Owners who skip this step end up hauling snow off site at their own cost.

Lots we build for industrial owners

Employee lots, visitor lots, truck parking, trailer staging and service-yard pavement all fall under this work, and each gets its own section. A staff lot may take a light asphalt section. A lot where loaded trailers park and turn needs concrete landing pads or a much thicker asphalt section, because standing wheel loads rut asphalt in summer heat. For those areas the design ties into our truck courts and trailer yards work.

Beyond the pavement we build the pieces that make a lot usable: curb and gutter, wheel stops, striping, accessible stalls, sidewalk connections, lighting conduit and signage. Accessible routes follow the rules covered under our site concrete and ADA compliance work, and we build them in the same earthwork sequence so slopes and cross-slopes get checked once, at the right time.

Codes, drainage and the permit counter

The International Code Council states that Wyoming has no single statewide building code. Cities and counties adopt and enforce their own, so requirements vary by jurisdiction. The Department of Fire Prevention and Electrical Safety adopted the 2024 International Codes on June 28, 2024, and Laramie County adopted them with amendments effective January 1, 2025. We call the local building and planning office before we draw a lot, because parking counts, drainage rules and accessibility requirements differ from one place to the next.

Paving a large lot changes how water leaves the site, and most jurisdictions want to see that on paper. Expect a grading plan, a drainage calculation and, on bigger disturbances, erosion control. We prepare that package with the lot design so review comments arrive once, not three times.

Subgrade first, pavement second

We open every parking project with a test pit and a proof-roll. Native soil near a plant can be anything: dense gravel, silty clay, old fill from a previous building. The answer drives the plan. Silty soils that pump water get a geotextile and a thicker base. Clays that swell get lime or cement treatment or an over-excavation. Granular soils can go quickly with a modest section.

Compaction is tested, not assumed. We take density readings on each lift of base and check thickness before paving starts. Asphalt goes down in the warm months on a compacted, dry base, because a cold mat does not compact and a wet base does not stay put. In shoulder seasons we use concrete or a stabilized aggregate surface and schedule paving for the next window.

Work that goes with the lot

A new lot almost always brings other site work. Conduit for poles goes in before the base is closed, which is why we coordinate with yard lighting and electrical site work instead of trenching through finished pavement. Concrete from dock aprons and loading zones often runs beside an asphalt car lot, and the transition has to be designed, not improvised.

Logistics and distribution sites run around the clock, and a closed gate costs real money. We cut the lot into sections, keep one truck route open and swap sections in the order that keeps the dock doors busy. Phasing takes longer on paper and saves days on the ground.

Where the money goes

Aggregate haul comes first, then pavement thickness, then drainage. Cheyenne Business Parkway shows what a prepared site looks like: 900 acres just east of central Cheyenne with high-volume natural gas, electricity and redundant fiber already in place. Site work there is mostly grading and paving. A remote site with nothing in the ground spends more on the base than on the surface.

Owners of flex and light-industrial buildings often ask whether concrete is worth the higher first cost. If the lot sees loaded trailers or forklifts turning on a fixed spot, it usually is. If it only sees cars, asphalt on a good base does the job. We give both prices with a maintenance outlook and let the traffic decide.

Send us the lot size and the heaviest truck

Give us the site address, the approximate area and the heaviest vehicle that will use it. We will review the soil and drainage conditions, propose a pavement section and return a price with a schedule that accounts for the weather.

Common Questions

Asphalt or concrete for a lot that sees loaded trucks?

Concrete wins where trailers park, turn or stand under load, because asphalt ruts under steady weight in summer heat. Asphalt wins for employee lots and long drive lanes where traffic keeps moving. Most industrial sites end up with both, joined by a designed transition. We price each zone separately so the owner can see what each choice costs.

Can the lot stay open while you work?

Usually yes. We break the lot into sections, keep a truck route and employee access open and rotate closures. Shift changes and dock peaks set the schedule. The tradeoff is more mobilizations and a longer calendar, which we state in the bid.

Does a new lot need stormwater detention?

Often. Adding impervious area increases runoff, and many jurisdictions limit how much can leave the site. The answer comes from the local drainage rules and the size of the surface. We check that early because detention takes land, and land is cheaper to set aside before the layout is fixed.

When is the best time to pave in Wyoming?

Late spring through early fall, on a dry base. Cold mix does not compact and a wet base will not hold. If the schedule forces a winter finish, we build the full base and a temporary surface and complete the paving when the weather allows.
