Start with crushed base for drives, shop pads and lanes. On this open plains ground, wind moves anything loose, so the material under the surface does the real work.

Materials Delivered in Platte County

Crushed base is the standard Wyoming base material. In this state, and Section 803.4.3 covers the material itself.

Gradings in Table 803.4.4-1 are lettered J, GR, L, K and W rather than numbered. Grading W is the common one-inch-top-size base and Grading GR is the 3/4 inch gradation, which is why you hear 3/4 minus on a job.

City and county work is usually written against Section 02190 of the Wyoming Public Works Standard Specifications, which uses the same grading letters and states that base shall be crushed base unless otherwise specified.

Pit run is a separate pay item from crushed base in both spec books. Order it for deep fill, raising grade and sub-base, never as a finished driving surface.

Sand and soil round out the list: Washed Sand for bedding under flatwork and pavers, Mason Sand for block work and joints, and Garden Soil for raised beds where native clay will not do.

Choosing the Right Material

Platte County sits on the Southeast high plains, and so do Laramie and Goshen counties. Silty, wind-laid soils over soft Tertiary sandstone, siltstone and Ogallala gravel show up across all three, with gravelly terraces and shrink-swell clays where Cretaceous shale reaches the surface.

Laramie County shares that ground region, so the base and drainage choice there follows the same reasoning as here. Crushed Stone from the hard-rock quarry west of Cheyenne turns up in yards around Laramie County, and it is not something you see elsewhere in Wyoming.

Albany County is the real difference. Its ground runs to the Laramie Basin, the Snowy Range and the southern basins, with alkaline and saline lake-bed soils and coarse granite grus washed off the ranges.

Saline ground changes the drainage call. Where salts sit in the soil, a clean washed stone that lets water move beats a fines-bearing material that holds it.

On Platte County ground, the wind-laid silt and shrink-swell clay push the same way: drainage first, then base.

Ground Conditions Across Platte County

Start with water and where it goes. Across the Southeast high plains, late spring and summer cloudbursts fall on hard, dry ground and run off fast instead of soaking in.

Snowmelt comes off subgrade that is still frozen, and clay lenses hold water under a drive rather than releasing it. A clean drainage layer under the surfacing gives that water somewhere to go.

Wind is the other driver on this open plains ground. It blows dust off bare lots and strips unbound surfacing, so a material that knits together holds better than loose stone.

After wind comes gully cutting in the draws and bank scour at high water.

The freeze-free season runs about 125 days in the farmed valleys. Base, drive and paver work goes in from spring breakup into autumn, and frozen ground stops compaction through the winter.

Winters here are cold, dry and open, with wide day-to-night swings. Chinooks off the Laramie Range thaw the surface and let it refreeze inside the same week, so gravel drives cycle all winter and heave in spring.

Frost depth is about 36 inches in Cheyenne and Laramie County, and the local building department sets footing depth. No frost figure was researched for Platte County, so treat the number as a regional reference and let your building official set footings here.
