Contra Costa County
Excavation in Contra Costa
Dig, trench, and move earth where the skid steer can't reach.
Mini-excavator work for jobs that need real reach and depth — utility and drainage trenches, footings and foundations, ponds, pools, large stumps, and tight-access earthmoving on lots full-size iron can't touch. Across Contra Costa County — from Concord, Walnut Creek, Antioch, and Brentwood — in the Diablo foothill towns the work is mostly fire mitigation and defensible space, while out in Brentwood and the East County it's land clearing for farmland and new home sites.

Local context
Why Contra Costa landowners need excavation
The grassy Diablo foothills above Lafayette, Orinda, and Danville sit squarely in the wildland-urban interface, and dry-season grass and oak woodland keep defensible-space compliance front of mind for hillside homeowners.

Common questions
Excavation FAQs
What's the difference between excavation and grading?+
Grading shapes the surface; excavation digs into it. A skid steer is great at spreading, leveling, and light cut-and-fill near the surface, but a mini excavator is what you want for trenches, footings, deep holes, and anything that needs to go down rather than across. Many operators bring both machines to a single job.
How much does excavation cost?+
Most mini-excavator work runs $90–$150 per hour with operator, while trenching is often quoted at $5–$15 per linear foot in normal soil. A small footing or foundation dig typically lands around $1,000–$3,000. Rock, high water tables, deep digs, and hauling spoil off-site all push costs up.
Do I need to call 811 before you dig?+
Yes — and any good operator handles it for you. California law requires a free 811 'call before you dig' utility locate at least two business days before breaking ground, on public or private property. It prevents strikes on gas, electric, and water lines. Never hire someone who skips it.
Will the machine fit through my gate or on my finished lot?+
Usually. Compact excavators in the 1.5–3 ton class fit through a standard ~36-inch gate and run on rubber tracks that spread weight to limit damage to lawns and driveways. For tight urban and finished-yard jobs, that small footprint is the whole advantage over a backhoe or full-size excavator.
Do I need a permit?+
It depends on the work. A private drainage trench often doesn't, but utility connections, septic systems, retaining structures, and anything in a creek setback or steep-slope area usually do. Your operator can tell you what's typical locally, but always confirm with your county or city before digging.
