Materials for Park City Projects

Decorative rock carries a lot of the landscaping work in the Wasatch Back. Beds, borders, park strips and dry creek beds all need stone that holds its place and sheds snowmelt.

Large River Rock, sold as 4 to 6 inch cobble, suits dry creek beds, swales and slope cover where fast runoff would move a smaller stone.

Wasatch Cobble works for decorative beds, borders and mow strips. Both are rounded stone, so they cover ground and look finished rather than bearing load.

Natural Pea Gravel finishes walkways, dog runs and play areas where a smaller rounded stone is wanted. It also surrounds pipe and helps drainage.

Every bed or landscape build still starts with a compacted base. Road Base is the untreated base course, or UTBC, that goes under driveways, parking pads, shed bases and paver work.

Utah yards and crews size it by top size, such as 3/4 inch minus or 1 1/2 inch minus.

For drainage, Drain Rock handles French drains, footing drains, window wells and downspout runs. Washed rock means the fines are gone, so water moves through it.

Ground and Conditions in Park City

Across the Wasatch Back and the mountain valleys, soils are thin and stony over bedrock on the slopes, with stream and glacial gravel in the valley bottoms and pockets of heavy clay in old meadow ground.

Rock sits close to the surface in a lot of places, which decides how deep anything can be dug. A shallow base over that ground will move, so depth and drainage matter before surface material goes down.

Snowmelt dominates the year. A deep snowpack releases over a few weeks and saturates the valley bottoms while the subsoil is still frozen, and steep ground sheds fast onto the floors and driveways below.

That runoff gullies cut slopes and drives and scours stream banks. Riprap and coarse clean stone armor those edges, while drain rock and washed stone move water away from structures.

The building season is short. Compaction is not practical on frozen ground, so base and paver work fits into late spring through early autumn.

Gravel drives take a beating from plowing all winter.

Freeze-thaw is severe as the ground opens in spring. Summit County frost depth is 36 inches under the 7/1/2026 design criteria, and deeper at the highest elevations.

Each jurisdiction sets its own figure.
