Owyhee County, ID Gravel and Landscape Rock Delivery
Idaho Rock Supply handles gravel, stone and aggregate delivery in Owyhee County, ID for two kinds of buyers. Contractors building drives, pads and shop floors order road mix by the load.
Homeowners in Homedale, Marsing, Grand View, Murphy and Bruneau order the same material in smaller amounts for a driveway, a path or a garden bed.
Road mix is the base material this part of Idaho runs on, and it is the same load whether you call it 3/4 road mix, road base or 3/4 minus. Ground here is thin desert soil with hard caliche layers underneath, so what goes on top matters.
Materials Delivered in Owyhee County
Road mix is crushed base with the fines left in, so it locks up under a roller and holds a firm surface. Idaho writes base material two ways.
State highway work follows the ITD Standard Specifications, where Section 703.04 covers Aggregate for Untreated Base, Treated Base and Road Mix and is the source of the 3/4 inch minus gradation, and Section 703.11 covers aggregate for granular subbase.
City, county and highway district work is usually written to the Idaho Standards for Public Works Construction, whose Section 802 covers crushed aggregate in Type I and Type II and Section 801 covers uncrushed aggregate. Those are how material is described on Idaho plans, nothing more.
Road mix goes under driveways, parking pads, shop floors and shed slabs. Order it as 3/4 Road Mix and you get the same gradation a contractor means by 3/4 minus.
Below and beside the base, the other materials do their own jobs.
- Pit Run is unprocessed gravel straight from the pit, rock and fines mixed at whatever sizes the pit gives. Idaho uses it as sub base under road mix, as structural fill and for filling holes and raising grade, never as a finished surface.
- Drain Rock, also called washed rock or 3/4 clean, is clean angular rock for french drains, foundation drains, drywells, septic drainfields and downspout runs. It comes in 3/4 inch, 1 1/2 inch and 2 inch.
- 3/4" Crushed Stone, called 3/4 chip or 3/4 clean chips, is angular rock that stays put. It surfaces drives and beds pipe where drainage is wanted.
- 3/8 Chip is a finer angular chip for pathways, leveling course and topping over a compacted base. Chips knit together, so unlike Natural Pea Gravel they stay where they are put.
- RipRap armors creek banks, culvert outlets, canal banks, pond edges and cut slopes against snowmelt and cloudburst runoff.
- Top Soil, sold screened and clean, is for lawns and bed prep over thin desert soil, basalt ground and stony mountain ground.
- Washed Sand, also called C33 sand or concrete sand, beds pavers and slabs, backfills and mixes into concrete.
- Snake River Rock, known locally as round rock, is round stone for decorative beds, borders, dry creek beds and water features.
Choosing the Right Material
Two neighbours share the ground Owyhee County sits on, and one does not. Ada County and Canyon County both sit in the Treasure Valley and the western Snake River Plain, the same ground region as this county.
That means the base and drainage choices you make here hold in Ada and Canyon County too. A base course over caliche behaves the same way on either side of the line.
Twin Falls County is different. Its ground is a thin blanket of loess and wind-laid silt loam over fractured basalt, with rock often within a few feet of the surface, plus river gravel and sand along the Snake and rimrock and talus at the canyon edges.
Rock that shallow changes drainage.
Ground Conditions Across Owyhee County
Across the Treasure Valley and the western Snake River Plain, the ground is old lake silt, sand and clay with basalt beneath, worked into irrigated silt loam on the valley floor.
Sandy and gravelly terraces run along the rivers, and hard caliche layers sit under thin desert soils on the benches and out into the Owyhee country.
A thin base over caliche is where drives fail first. Water that gets through the soil stops at the caliche and sits on top of it, so the base softens and ruts under a wheel.
Clay lenses and shallow basalt perch water under yards and drives here. Irrigation canals and laterals hold the summer water table high across the valley floor, and summer cloudbursts run straight off crusted desert soil instead of soaking in.
Runoff off the Boise Front after fire and cloudbursts, canal and ditch bank scour, furrow erosion on irrigated ground and spring wind moving dry bare soil are the erosion drivers to plan around. Riprap on banks and outlets, and a stone layer where water collects, both answer that.
This is the mildest of the southern Idaho zones. Cold nights and mild days give many shallow freeze and thaw cycles through the winter rather than one deep freeze.
