Excavation in Yavapai County
Soil regimes, rock depth, haul logistics and the contractors who work Yavapai County, Arizona — the local ground data behind every bid.
Yavapai County is home to roughly 252,013 people, part of the Prescott Valley-Prescott, AZ metro area, growing about 7.2% over the last five years, covering about 8,123 square miles of land — a metropolitan-adjacent county of Arizona where site work scales with the building cycle.
Ground conditions
The Colorado Plateau's stripped-bedrock terrain, mesas, buttes, and dissected tablelands across northern Arizona, puts shallow sandstone, shale, and limestone saprolite under thin eolian and residual soils. Median restrictive depths of 12 to 24 inches are normal; mass excavation becomes rock excavation quickly, and pad building means benching into flat-lying sedimentary strata. Sandstone rips with a big hoe where fractured; shale weathers to a slick, expansive clay that swells under slabs and eats subgrade uniformity. Fine eolian sand and loess cap the mesas, stable when dry, instantly unstable when saturated, with caving trenches and spongy subgrade after storms. Water tables are hundreds of feet down; the water challenge is surface flow, with summer monsoon runoff concentrating in slot canyons and arroyos. Utility trenching crosses intact rock ribs that require hammer work; plan mobilization for rock breakers and expect crushed-rock borrow to dominate backfill economics.
Dominant soil textures include loam, sandy loam, clay loam; 53.4% of the county has bedrock or a restrictive layer within 50 inches of the surface — rock clauses belong in every bid; the median water table sits about 30 inches down, so dewatering is routine on deeper cuts; 50.4% of the land slopes steeper than 15%, which narrows machine choices and raises erosion-control stakes.
| Soil regime | Colorado Plateau Mesa & Canyon Shallow Soils |
|---|---|
| Dominant soils | Loam, Sandy loam, Clay loam |
| Shallow bedrock (≤50 in) | 53.4% of county |
| High shrink-swell soils | 9.5% of county |
| Median water table | 30 in deep |
| Slope >15% | 50.4% of county |
Haul costs & materials
Haul distance moves county prices more than machine rates do. Here, the nearest major aggregate source is Fain Pit, about 3.8 miles out (with 11 active quarries within 50 miles).
Construction demand
Construction demand sets how busy crews are and how far out they book. 1,335 single-family permits were issued in the last 12 months (a -8.4% three-year trend), and 1,706 total housing units across all types, and About 4,633 residents work in construction, and 66 site-prep establishments are registered in the county.
Rough cost estimator
Bulk excavation is commonly priced per cubic yard — roughly $2 to $8 for ordinary soil and far more where rock must be hammered, which applies to a meaningful share of this county. Use the table for ballpark volumes, then confirm with line-item bids from Yavapai County crews.
| Project volume | Typical range | What it covers |
|---|---|---|
| 100 cubic yards | $200 – $800 | Pool hole or small trenching job, easy soil |
| 500 cubic yards | $1,000 – $4,000 | House pad cut or driveway cut on easy ground |
| 1,000 cubic yards | $2,000 – $8,000 | Basement dig or modest site cut, before hauling |
| Rock excavation | $40 – $100+ / cubic yd | Hammered or blasted rock, priced separately |
| Machine + operator | $100 – $250 / hr | Hourly rate for mid-size excavator or dozer |
National ranges, not a quote: bulk excavation is usually priced per cubic yard, roughly $2 to $8 for ordinary soil and $40 to $100 or more where rock has to be hammered or blasted. Rock, groundwater and haul distance move the number most.
