Why Beaverton Homeowners and Builders Choose Us

Beaverton is not a one-grade town. The city sits on the eastern edge of the Tualatin Valley, but it also climbs toward Cooper Mountain, Sexton Mountain, Highland, and the West Slope. That elevation relief changes excavation: pads need cut-and-fill, drainage has to catch water coming off high ground, and access can matter as much as the soil.

The low ground has its own story. Beaverton was once called Beaverdam, and the older wetland pattern still shows up in clay that holds water near Fanno Creek, Beaverton Creek, and Johnson Creek. We know when a site needs drainage first, when fill needs compaction in lifts, and what the City of Beaverton and Clean Water Services expect before disturbed soil leaves the property.

Straight, itemized quotes. You get a written estimate that spells out scope and cost. No surprise change orders.
We show up. Crews arrive when scheduled and keep you posted if weather moves the plan.
Drainage done right. We build water management into every grade, which matters more here than almost anywhere.
Permits handled. Grading permits, erosion control, and DEQ 1200-C coverage when the job needs it.
Clean sites. Spoils hauled, debris gone, grade left ready for the next trade.
Licensed and insured. Proof of coverage before we break ground.

How Much Does Excavation Cost in Beaverton, OR?

For most Beaverton homes, an excavation project lands between $1,500 and $6,500, and where it falls comes down to the volume of material moved, how steep your lot sits, what the soil and rock throw at us, and how easily equipment can reach the work. Figure on roughly $110 to $190 per hour for an excavator and operator, plus about $60 to $120 per cubic yard to truck spoils away. The ranges below reflect what we typically see around Washington County, so you can set a budget before we ever roll up.

Project	Typical size	Typical Beaverton cost
Residential site prep (home pad)	1/4 – 1/2 acre	$2,500 – $8,000
Land clearing (light brush)	per acre	$1,500 – $3,500
Land clearing (wooded, stumps)	per acre	$3,500 – $9,000
French drain / drainage system	100 – 150 ft	$1,800 – $5,500
Utility trenching	per linear foot	$12 – $30
Foundation / footing excavation	average home	$2,000 – $6,500
Gravel driveway (build)	16 ft × 100 ft	$2,500 – $6,000

Ranges are typical for the Beaverton / Washington County area and include excavation, basic grading, and cleanup. Rock, steep slope, poor access, or heavy winter saturation can raise costs. We give a firm, itemized quote after a free site visit — no obligation.

Frequently Asked Questions

How much does excavation cost in Beaverton, OR?

Most Beaverton residential excavation projects run $1,500 to $6,500. Equipment-and-operator time is commonly $110 to $190 per hour, spoil haul-off is often $60 to $120 per cubic yard, and home-pad site prep usually falls between $2,500 and $8,000. Slope, clay, rock, access, and drainage decide the final number.

Do I need a permit to excavate or grade in Beaverton?

Often, yes. Significant grading may require a City of Beaverton or Washington County permit, Clean Water Services erosion control applies to most disturbed sites, and Oregon DEQ 1200-C coverage is required for one acre or more of disturbance. We check the scope and handle the permit and erosion-control pieces.

How long does an excavation project take?

Many Beaverton grading or site-prep jobs take one to three working days once permits and layout are ready. Wooded clearing, drainage systems, hillside cut-and-fill, or wet clay can extend the schedule to three to five days or more. Weather matters most from October through May.

Do you work in winter and the rainy season?

Yes, with wet-season methods. Beaverton clay holds water, and hillside runoff can move fast, so we plan access, drainage, compaction, and erosion control before opening the ground. If a storm window would damage the site or prevent proper compaction, we tell you before forcing the work.

Are you licensed and insured?

Yes. Beaverton Excavation Co. is licensed and insured for excavation work in Beaverton and Washington County, and we can provide proof of coverage before work begins. That protects you, the site, and the other trades working around the excavation.
