A plant with 2,100 employees puts a lot of cars on pavement twice a day, and the lot has to work through January. Fort Morgan's beef plant is described as employing around 2,100 people, and the same operator opened an 81-unit employee apartment complex in December 2025. Shift change at that scale concentrates demand on a few entry points, so the lot is a flow problem before it is a paving problem.
Industrial parking differs from retail parking. Shift change creates a surge, not a steady trickle. Visitor, contractor and truck-driver parking must be separated from employee lanes. Emergency vehicles have to reach the building face without crossing a queue. We design lots around those flows, then specify a stabilized base and surface that will survive the snow removal equipment, delivery vans and the occasional overloaded truck that ends up where it should not.
Where a lot sits next to a truck court, we separate the two with curbs, grade breaks or barriers, and coordinate the interface with truck courts and trailer yards so trailers do not cut across employee entrances. That separation is also a safety measure, and it keeps heavy wheel loads out of light-duty pavement.
Flow, shift change and snow storage
The first drawing we ask for is a shift-change diagram: how many vehicles enter in the 15 minutes before a start time, where they queue and where they turn. Entry throat length, gate controls and the distance from the lot to the employee door all follow from it. Denver averages about 49 to 54 inches of snow a year depending on station and period, which means the lot must also hold plowed snow somewhere that does not block lanes or pond against the building.
We allocate snow storage on the plan, usually along an edge that drains away from the building, and we set the grading so melt does not cross a walking route and refreeze. Light poles, bollards and curb islands are placed to survive a plow blade. Those details look minor on a drawing and decide whether the lot works in the third week of a cold February.
Pavement section, drainage and the local review
Colorado commercial codes are set city by city and county by county. The Home Builders Association of Metro Denver tracker dated January 20, 2026 shows Adams County, Arvada and Castle Rock on the 2018 I-codes, Aurora and Arapahoe County on 2021, and Boulder, Golden and Cherry Hills Village on 2024. Parking counts, landscape islands, lighting levels and stormwater treatment are local rules, and we read them against your parcel before layout begins.
The pavement design follows the geotechnical report: subgrade preparation, aggregate base thickness and asphalt or concrete surface selected for the traffic mix. In expansive clay, subgrade moisture conditioning matters as much as base depth. Detention and water-quality requirements usually push parking onto a drainage plan shared with stormwater detention and drainage, so the two are designed together.
What we build inside the curb line
Scope covers clearing and subgrade work, base placement, curb and gutter, asphalt or concrete paving, striping, signage, accessible stalls and routes, wheel stops where required, and inlet structures. We coordinate with the lighting package so conduit crosses the base before paving, and we leave sleeves under drive lanes for future irrigation or communications work. Retrofitting these later means saw-cutting new pavement, which is a waste on a job we have already built.
Accessible routes and curb ramps are built to meet the standards that govern them, and we integrate them with the sidewalk network described under site concrete and ADA compliance. For distribution sites, we add trailer drop areas, bike and EV charging provisions where the owner calls for them, and a clear way to the visitor entrance.
Where these lots serve best
Fulfillment sites feel the demand sharply. A roughly one million square foot fulfillment center on Smith Road in Aurora was announced with about 1,000 full-time jobs, and a site that size runs multiple shifts with overlapping parking demand. Our design for those facilities handles shift overlap, staging for temporary seasonal staff and the separation of van and employee traffic. See how we approach logistics and fulfillment centers in detail.
Manufacturing plants need the opposite emphasis: fewer vehicles, more contractor and visitor parking, and cleaner separation from hazardous material routes. Small-bay flex buildings such as the 133,133 square foot Compark470 pair in Parker need a ratio of stalls to bays that suits many small tenants. We size the lot from the use, not from a default ratio.
Pairing the lot with the rest of the site package
Parking is rarely a separate contract in practice. The same grading plan sets elevations for the lot, the building pad and the detention basin, and the same utility trenches cross all three. We carry the parking work inside the site package so those pieces are scheduled in order, not discovered against each other. The lot is also where temporary construction parking lands, so many owners ask us to build the permanent base first and use it during construction.
If the project serves e-commerce operations, our work for ecommerce fulfillment buyers shows how we combine dock, yard and parking into one traffic plan. For overall site lighting that supports night shifts, yard lighting and electrical site work is the natural companion scope.

Common Questions
Asphalt or concrete for an industrial parking lot?
Passenger-car parking usually performs well in asphalt, and it is faster and cheaper to place and repair. Concrete earns its cost where trucks turn, where fuel or hydraulic oil may drop, or where the owner wants minimal maintenance. We price both against the traffic mix and the life-cycle your finance team uses.
How many stalls does an industrial building need?
The local zoning code sets a minimum, and it varies by city and by use category. Many municipalities count warehouse area differently from office or manufacturing area. We read the parcel's rules first, then compare the code minimum against your shift count, because a code minimum sometimes falls short of real shift overlap.
Can we phase the lot so part is available during construction?
Yes. We often build the permanent base for employee and contractor parking early so workers have a firm place to park. The final wearing course goes down last, which protects it from construction traffic and gives the cleanest finish.
How do you handle drainage on a flat site?
Flat grades demand careful slope design, because even small errors create birdbaths. We hold minimum slopes in the pavement design, use inlets and valley gutters where needed, and tie into the detention plan. We survey finished grades before paving so corrections are made while the base is still open.
What does it cost to restripe and maintain?
Stalls and arrows typically need refreshing as traffic wears them, and crack sealing extends asphalt life. We provide a maintenance outline in the turnover package so your facilities team can budget the work.
