Materials delivered in Grand County
Untreated base course is the base course of natural gravel, crushed rock or crushed slag placed on a prepared subbase or subgrade.
City and county work follows the APWA Utah Chapter Manual of Standard Specifications, where the matching section is 32 11 23 Untreated Base Course. Utah yards shorten the material to UTBC and sell it by top size, 3/4 inch minus or 1 1/2 inch minus.
Road base is the catalogue name for the same compacting material.
Below that, the supporting materials split by what the ground and the drainage need.
Natural Pea Gravel and 3/8 inch chip cover the finer work: walkways, play areas, dog runs, pipe bedding, paver joints and a thin topping over a compacted base. Rounded landscape cobble goes into decorative beds, borders, park strips and dry creek beds.

Ground conditions across Grand County
Across the Canyon country and the Castle Valley shale, the ground is red sandstone derived sand and thin rocky soil over slickrock.
In the shale country it turns to deep shale clay that swells when it is wet and shrinks and cracks as it dries, and it runs alkaline, low in organic matter and gypsum bearing in places.
Summer monsoon cloudbursts run straight off slickrock and hardpan into the washes, and shale clay sheds almost everything that falls on it. Water standing on shale clay is what ruins a base here, so a thin base shows its failure first at the edges and in the low spots.
The fix is a compacted base course over ground that drains, with a clean stone layer where water collects. Flash flooding in the washes and arroyos, gullying in the shale badlands and wind moving sand off the benches are the erosion drivers to plan around.
Frost moves a lot with elevation here. No single figure applies across the county, and footing depth is set locally by the building official, so confirm it for your site before you build.
Choosing the right material
Emery County and San Juan County both sit on the same ground region as Grand County, red sandstone derived sand and thin rocky soil over slickrock, with deep shale clay in the shale country. The ground is the same, so the base and drainage reasoning carries over.
What changes on any of it is elevation and how much water a site takes. A pad on thin sand over slickrock drains fast; a pad on shale clay holds what falls on it.
Match the material to that.
Compact your base over ground that drains, and put clean stone where water collects. On the fines side, crusher fines bed pavers and surface paths, while washed sand levels under pavers and slabs.
Questions about gravel and base in Grand County
How deep should a gravel driveway base be in Grand County?
Depth is set by what the driveway carries and by the ground under it, not by a single county figure. Thin sand over slickrock and deep shale clay behave differently, and the clay holds water that a base has to shed.
Set the base over ground that drains, and put clean stone where water collects. Your project's own plans or engineer settle the number.
