Start with road mix. It is the crushed base with the fines left in, and it locks up under a roller.
It goes under drives, parking pads, shop floors and shed slabs across Nez Perce County.
Materials for Lapwai Projects
Road mix carries the base work here. Idaho yards call crushed base road mix, and a contractor asking for 3/4 minus means the same load.
Both names point to one product: 3/4 Road Mix.
On public works plans in Idaho, that base is written as crushed aggregate and called out by type rather than by a class number. Same material, different paperwork.
Under the base, pit run does the structural work. It is unprocessed gravel straight from the pit, rock and fines at whatever sizes the pit gives.
Use Pit Run as sub base, as fill, or to raise grade before a base course goes on. It is not a finished surface.
Where water has to move, drain rock is the clean angular option. Idaho sells it as washed rock or 3/4 clean, in 3/4 inch, 1 1/2 inch and 2 inch sizes.
It suits french drains, foundation drains, drywells, septic drainfields and downspout runs.
For a walking surface, 3/8 chip knits together and stays put. Natural Pea Gravel is round and uncrushed, so it rolls underfoot; use it for patios, dog runs and play areas instead.
Sand and soil round out a yard build. Washed concrete sand beds pavers and slabs, mason sand handles brick and block work and paver joints, and garden soil fills raised beds where the native ground is too thin or too alkaline to plant into.
Ground and Conditions in Lapwai
Across the Palouse hills and the Clearwater and Snake canyons, the ground is deep windblown loess lying on Columbia River basalt. Silt loam over loess seals under rain and sheds water instead of taking it in.
That is the whole drainage problem in one sentence. Long slopes push runoff onto roads, drives and yards, and water perches where the loess sits on basalt.
So a drive here needs a base that stands up to water moving past it, and a drainage layer where water has nowhere to go. Sheet and rill erosion on cropped loess slopes in this part of the state runs heavy, and canyon roads, culverts and creek banks scour under spring runoff and summer cloudbursts.
Rip rap armors creek banks, culvert outlets, canal banks, pond edges and cut slopes against that. Cobble and large river rock do similar work in dry creek beds and swales at a smaller scale.
Timing matters as much as material. Sticky loess mud through the wet months is the real constraint, and hauling and compaction go best from late spring through fall.
The canyon towns get a longer window than the prairie above them.
Winters on the prairie are cold and wet, with frequent freeze and thaw cycles. No published frost depth was found for these counties, and Idaho code leaves the frost line to the local jurisdiction, so the building official sets it.
