Warehouse and Storage Building Construction in Afton, Wyoming

Warehouse, cold storage, shop and dry storage buildings in Afton, Wyoming, engineered for Star Valley snow loads and US Highway 89 truck access.

Eighty-eight inches of snow a year, a record low of minus 46 F and one main highway through the valley: Afton is a place where a warehouse is judged in January. Afton sits at 6,240 feet in Star Valley, a 56 mile long valley in Lincoln County that ranges from 5,600 to 7,000 feet in elevation. US Highway 89 runs the full length of the valley, through Afton as four lanes spanned by the town's elk antler arch, and Wyoming Highway 236 connects Fairview and Afton. We build storage, shop and distribution buildings for operators on that single corridor, with roofs and slabs sized for the weather.

Afton averages about 87.8 inches of snow a year, with the heaviest snow from November through January. Anyone who has watched a roof carry that load knows the building has to be right the first time. We design for drifts at the dock and the roof edges, give snow somewhere to go besides the truck court and choose finishes that survive the temperature swings of a high mountain valley.

Valley freight is local freight. Feed, propane, building materials, groceries, auto parts and farm supply move on trucks that serve Star Valley and return the same day, so the building at Afton works as a spoke rather than a hub. Operators who also serve Jackson or Kemmerer use it as a stocking point for the western corridor.

A valley economy built on milk and now on mixed trades

Afton is in the Upper Valley of Star Valley, where dairy farming was once central. The valley had 600 dairies in 1947 and about 175 farms by 1982, and the Thayne Creamery closed in 2005. The change from a dairy-centered economy to a mixed one left buildings that were designed for agriculture and a market that is still looking for the next use.

For a builder, that history means two things. First, the valley has people who understand food handling, cold storage and refrigerated trucking, even though much of the processing has gone. A food-grade warehouse or a small cold room still has a logical customer base. Second, some of the old agricultural buildings are worth examining for reuse. We assess a structure's slab, frame and utilities before recommending a rebuild or a new shell.

Cold-weather numbers and local plan review

Design snow, wind and frost values are set locally in Wyoming and vary widely. Evanston, to cite one Wyoming example, requires a 40 psf minimum snow load and footings at least 54 inches below finished grade. Those numbers are not Afton's, and a mountain valley may differ from both, so we obtain the local jurisdiction's published design criteria before the engineer starts.

The International Code Council notes that Wyoming has no single statewide building code, and the state's 2024 codes were adopted on June 28, 2024. We confirm which edition the local building office is enforcing and when it adopted it. We list the confirmation in the drawing notes, so a plan reviewer and an owner work from the same set of rules.

Who builds in Star Valley

Agriculture and light manufacturing are the traditional users. The valley's dairy tradition and its mix of small farms still support feed dealers, equipment shops, hay storage and a handful of specialty food producers. We build for them with cold-chain food standards when the product requires it, including insulated panels, vapor retarders and sanitary floor finishes.

Building materials suppliers and general contractors are the other steady users. A town with long winters sells a lot of insulation, windows and roofing in the fall and has to hold the stock until spring. A covered, dry warehouse with a dock and a lumber rack beats a fenced yard every time, and we design those with a roll-up door at each end so a flatbed can drive through.

Highway frontage on a four-lane main street

US 89 through Afton is a four-lane street that carries tourists, locals and freight. A commercial driveway needs to be placed to keep trucks from backing into traffic. We design the truck court so that a delivery truck can enter, turn and leave facing forward, and we coordinate the approach with the town and the state highway agency as needed.

Because Star Valley has one main road, any lot with direct access commands attention. We walk the parcel, check the setbacks and check for utilities along the frontage before we complete a plan. If a lot's best frontage is on a side street, we may suggest a design that works with the town's pattern rather than fights it.

Cold, ice and the work around them

Working at 6,240 feet in winter calls for thought. We stage cold-weather work, use heated enclosures for concrete and masonry, and rely on spotters and traction on icy ground. Equipment is kept plugged in overnight, and a pre-engineered metal building erected in a short dry window goes up with its snow load already engineered, and we monitor the forecast daily so we can shift crews to interior work when the weather turns.

After the building opens, safety continues in the details. We recommend canopies over personnel doors, heat-traced drains at the dock apron and roof snow guards over entries, so an owner does not face ice falling on a customer. Those items cost little during construction and avoid expensive fixes later.

Tell us the freight and the snow

Send the lot, the products you handle and the trucks that serve you. We will check the snow load, the permit path and the US 89 approach and come back with a building you can plan around.
