Bothell · Snohomish County
Excavation Contractor in Bothell, WA
Foundation digs, footings, utility trenches and building pads in Bothell, dug to spec by an owner-operated crew with its own excavators and dump trucks. Serving Downtown, Canyon Park, Thrasher's Corner and Westhill and the rest of Bothell.
What the ground is like for excavation in Bothell
The Sammamish River valley runs through downtown, with North Creek cutting north through Canyon Park. Westhill and the north end climb onto upland plateaus with some steep side slopes. That shapes every excavation job here: where the machine can sit, how trucks get in and out, and where the spoil goes before it is hauled away.
Valley bottoms are soft river deposits with a high water table. The hills are glacial till, firm to dig but slow to drain. On a Bothell foundation that decides how deep we go to reach bearing soil, whether unsuitable material has to be over-excavated and replaced with compacted structural fill, and how we keep water out of the hole while forms go in.
The Sammamish River, North Creek and their tributaries are salmon-bearing streams with wide buffers, and much of the North Creek corridor is protected wetland. If your footprint, trench or driveway lands near any of that, the excavation plan has to respect the buffer, and erosion control goes in before the first bucket.
Common excavation projects in Bothell
New home and ADU foundations
Footprints for new houses, ADUs and garages on infill and teardown lots around Downtown and Canyon Park, dug to the elevations on your plans and ready for forms.
Shop, barn and arena pads
Stripping topsoil, building a compacted rock base and grading for drainage so a shop, barn or arena on Bothell acreage sits dry and level.
Hillside cuts and daylight basements
Excavation on sloped Bothell lots, with spoil hauled off as it is dug instead of stockpiled on the slope, and temporary erosion control in place first.
Over-excavation and structural fill
Where Bothell ground is soft, we dig out the unsuitable material and place compacted structural fill in lifts so the footing bears on something solid.
Utility and water line trenches
Trenches for water, power, sewer and gas service from the street to the house or shop, backfilled and compacted, anywhere from Thrasher's Corner to the edge of Bothell.

Permits & Rules
Excavation permits and utility locates in Bothell
Inside city limits, the City of Bothell handles building and grading permits. Properties outside city limits fall under Snohomish County Planning and Development Services (PDS). Foundation excavation is usually covered by the building permit, while grading or fill over set volumes, or any work in a critical area, can need its own approval.
Before any digging, Washington law requires a utility locate through 811 at least two business days ahead. We place that call on every job, and we pothole near marked lines instead of trusting paint alone.
Cost & Timing
What affects the cost of excavation in Bothell
We do not publish flat prices because no two Bothell sites are the same. These are the things that move the number most here.
Slope and access
Steep Bothell lots take smaller machines, more careful staging and sometimes engineering, which adds time compared with flat, open ground.
Soft ground
Where Bothell soils are soft or wet, over-excavation, fabric and imported rock are often part of the job, and we price that in up front.
Size of the property
On Bothell acreage, longer haul distances inside the property and bigger volumes change the math. Bigger jobs often cost less per unit.
Haul-off and disposal
How much material leaves the site, and what it is, drives cost. Our own trucks keep that predictable on Bothell jobs.
When to schedule excavation in Bothell
Excavation in Bothell goes best in the drier months, when soil compacts properly and trenches stay open. Wet-season work is doable with erosion control and the right material, and we plan for it in the quote.
Bothell's till soils hold water through the winter, which is when drainage problems show up. That is a good time to see where water goes, and the dry season is the time to fix it.
Where We Work
Excavation across Bothell
Bothell straddles the King and Snohomish county line, and the City of Bothell handles permitting on both sides. Downtown has been almost completely rebuilt in the last decade, and the north end around Canyon Park and Thrasher's Corner keeps adding homes on former wooded parcels.
We dig foundations, ADU and garage footprints, septic and utility trenches, and building pads across Downtown, Canyon Park, Thrasher's Corner, Westhill, Maywood, Queensborough and Country Village. A mix of older homes near downtown and Westhill, 1980s and 90s subdivisions in the north end, and new construction on subdivided acreage.
Our trucks run in and out on I-405, SR 522 and SR 527 (Bothell-Everett Hwy), so spoil haul-off and fill delivery happen on our schedule instead of a subcontractor's.
We also do excavation nearby in Kenmore, Woodinville, Brier and Lake Forest Park. See everything we do in Bothell, read our full guide to excavation, or browse all service areas.

Questions
Excavation Contractor in Bothell: FAQs
What kind of soil will you hit digging in Bothell?
+
Valley bottoms are soft river deposits with a high water table. The hills are glacial till, firm to dig but slow to drain. We read the ground on the site walk and spell out in the quote how footing depth, over-excavation and imported fill are handled, so there is no surprise invoice.
Who issues excavation and grading permits in Bothell?
+
Inside city limits it is the City of Bothell. Outside them it is Snohomish County Planning and Development Services (PDS). We confirm which applies to your parcel before quoting and flag anything that needs extra review, like a stream buffer or steep slope.
Can your trucks and excavator get onto my Bothell site?
+
Almost always. We run compact and full-size tracked excavators and size the machine to the access. On tight lots we protect driveways and lawns with mats and stage trucks so the street stays open.
How much does excavation cost in Bothell?
+
It depends on the site, so we quote after a free site walk rather than guessing on the phone. The biggest drivers in Bothell are usually slope and access, soft ground, size of the property. You get a written number with inclusions and exclusions spelled out.
When is the best time to schedule excavation in Bothell?
+
Excavation in Bothell goes best in the drier months, when soil compacts properly and trenches stay open. Wet-season work is doable with erosion control and the right material, and we plan for it in the quote.
Is Bothell in King or Snohomish County for permits?
+
Both. The city limits cross the county line, but inside city limits the City of Bothell is the permitting authority either way. Outside city limits, the county your parcel sits in takes over.
Can you clear a wooded lot near North Creek?
+
We can clear what the rules allow. Land near North Creek or its tributaries usually carries a stream buffer that has to stay vegetated. We map the buffer on the site walk so the clearing plan and the quote match what can actually be done.
What happens if you hit rock?
+
Rock, groundwater and buried debris are excluded from every quote, because no one can price what they cannot see. If we hit it, work stops and we price the additional scope before continuing. You are never billed for a surprise you did not approve.
