Mass Excavation and Earthwork in Sunnyside, WA

Mass Excavation · Sunnyside, WA

Big cuts and fills for shops and commercial sites

Mass excavation is earthwork on a big scale: large cuts and fills that reshape a whole site. Bedrock Excavation and General Contracting does this work for shops and commercial sites. We take dirt off the high ground and place it on the low ground until the grades are right. When a site has extra dirt or runs short, we haul dirt and gravel in or out ourselves.

Sunnyside sits at the center of our service area, and we work about 50 miles around it. That reaches Yakima and the Tri-Cities, and bigger mass excavation jobs farther out in Washington are quoted on request. Smaller digging jobs fall under our excavation work in the Sunnyside area. Call or text (509) 439-2533, and we look at the site and put the quote in writing.

What does cut and fill earthwork involve?

Cut and fill starts with the finished grades the site needs. Topsoil and roots come off first, so the fill rests on firm ground. Then the high ground gets cut down, and that dirt fills the low spots.

Fill goes down in layers, and each layer is compacted before the next one goes on. What goes into the fill matters too. Outside city limits, Yakima County allows dirt and rock as fill, but not tree stumps or asphalt.

When the cut and the fill come out close to even, little dirt has to leave the site. When they do not, the difference gets hauled in or out. The earthwork ends at rough grade, and the site is ready for the building pad.

Commercial excavation and site excavation for shops

We work for businesses that need a shop or a commercial site prepared. Commercial excavation shapes the building area and the yard around it to the grades on the site plan.

Yakima County's grading permit asks for a site plan with the existing contours and the finished grades. It also wants the largest cuts and fills, and where any removed dirt will go. The county figures the job's size by adding up the cubic yards of every cut and fill. Inside Sunnyside, the city's commercial checklist asks for a soils report too.

Site excavation for a shop is the first half of the project. When the dirt work is done, we can put up the shop building itself. Utility lines are another trade's work, and they go in once the site is ready.

Dry soil and earthmoving rules from Sunnyside to the Tri-Cities

USDA soil maps show Warden soils under much of the ground around Sunnyside. Warden is deep, well-drained soil: wind-blown silt over old lake deposits. On the slopes north of town, USDA soil data show a cemented hardpan about two feet down in places. In Pasco, the most common soil is Quincy loamy fine sand.

The Benton Clean Air Agency warns that high winds can raise dust from dry, disturbed soil. The Yakima Regional Clean Air Agency wants a dust control plan for sites that could raise significant dust. That plan goes to the agency 15 days before work disturbs the soil.

In Benton County, the clean air agency wants a soil destabilization notice before soil-disturbing work starts. The county and its cities ask for a copy before they issue permits. In West Richland, a grading job over 500 cubic yards also needs a SEPA checklist for state environmental review.

FAQ

Mass Excavation Questions, Answered

Common questions about mass excavation around Sunnyside and the towns out to Yakima and the Tri-Cities. If yours is not here, call or text and ask.

Call (509) 439-2533

How is mass excavation different from site prep?
Mass excavation moves dirt across a whole site, with big cuts and fills. Site prep gets one lot ready for a building, from clearing through the backfill around the foundation. A large project can call for both, and we handle both.
How much does mass excavation cost?
The amount of dirt that moves sets most of the price, along with how far it travels. Hauling dirt off or bringing fill in adds to it, and so do dust and erosion control. Hardpan or rock in the cut changes the digging, and tight access slows the work. We look at the job and put the quote in writing.
Can you haul dirt in or out of the site?
Yes, we haul dirt and gravel ourselves. Extra dirt from a big cut goes out by the load, and fill comes in for the low spots. The written quote shows what leaves the site and what comes in.
Do I need a permit for cut and fill work?
Inside Sunnyside city limits, most cut and fill work needs an erosion and sedimentation control permit. The city's Public Works Director reviews the plan for a cut and fill design that limits erosion. The City of Yakima requires a grading permit whenever cuts or fills are proposed. Elsewhere, the city or county permit office answers that question, and we point you there.
Does a big earthwork job need a stormwater permit?
The Washington State Department of Ecology requires construction stormwater coverage when work disturbs one acre or more. The rule applies if runoff could reach surface water, and Ecology says that is true almost everywhere. Around Sunnyside, ditches lead to the Sulphur Creek Wasteway, which flows into the Yakima River. The application goes in at least 60 days before stormwater leaves the site.
Who calls 811 before the digging starts?
Washington's dig law puts the 811 notice on whoever does the digging. The notice goes in two to 10 full business days before work starts. Since January 1, 2026, digging cannot start until every utility in the area has responded. The marks expire 45 days after the notice, so a long job needs a new one.
