Arlington · Snohomish County
Excavation Contractor in Arlington, WA
Foundation digs, footings, utility trenches and building pads in Arlington, dug to spec by an owner-operated crew with its own excavators and dump trucks. Serving Downtown Arlington, Smokey Point, Arlington Heights and Kent Prairie and the rest of Arlington.
What the ground is like for excavation in Arlington
Flat river valleys along the Stillaguamish forks, with the Arlington plateau and Smokey Point to the south and west and wooded hills rising to the east. 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 river silts and sands with high groundwater. The plateau is largely glacial outwash, sandy and gravelly and well-draining, which is good digging. On a Arlington 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.
Both forks of the Stillaguamish and their tributaries carry wide stream buffers and floodplain rules. Many rural parcels also have wetlands or ditches to work around. 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 Arlington
New home and ADU foundations
Footprints for new houses, ADUs and garages on infill and teardown lots around Downtown Arlington and Smokey Point, 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 Arlington acreage sits dry and level.
Over-excavation and structural fill
Where Arlington 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 Arlington Heights to the edge of Arlington.
Private roads and long driveways
Cutting and building gravel access roads and long private drives on Arlington properties, with ditches and culverts so water leaves the road.

Permits & Rules
Excavation permits and utility locates in Arlington
Inside city limits, the City of Arlington 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 Arlington
We do not publish flat prices because no two Arlington sites are the same. These are the things that move the number most here.
Soft ground
Where Arlington soils are soft or wet, over-excavation, fabric and imported rock are often part of the job, and we price that in up front.
Buffers and permits
Work near Arlington's rivers, creeks, lakes or shoreline can need permits and limits on where machines go. That affects scope and schedule more than price.
Size of the property
On Arlington 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 Arlington jobs.
When to schedule excavation in Arlington
Excavation in Arlington 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.
On Arlington's floodplain ground, the river sets the calendar. Low-lying work is planned for the dry season, after high water has dropped.
Where We Work
Excavation across Arlington
Arlington is where the north and south forks of the Stillaguamish River come together, and the area around it is farms, horse property, timber and fast-growing neighborhoods near Smokey Point and the airport. Pasture clearing, big tree removal and site prep for shops and new homes are everyday work here.
We dig foundations, ADU and garage footprints, septic and utility trenches, and building pads across Downtown Arlington, Smokey Point, Arlington Heights, Kent Prairie, Bryant and Oso area. A historic downtown, new subdivisions toward Smokey Point, and a lot of acreage with barns, arenas, shops and pastures.
Our trucks run in and out on I-5, SR 530, SR 9 and 172nd St NE (SR 531), so spoil haul-off and fill delivery happen on our schedule instead of a subcontractor's.
We also do excavation nearby in Marysville, Lake Stevens, Everett and Snohomish. See everything we do in Arlington, read our full guide to excavation, or browse all service areas.

Questions
Excavation Contractor in Arlington: FAQs
What kind of soil will you hit digging in Arlington?
+
Valley bottoms are river silts and sands with high groundwater. The plateau is largely glacial outwash, sandy and gravelly and well-draining, which is good digging. 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 Arlington?
+
Inside city limits it is the City of Arlington. 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 Arlington 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 Arlington?
+
It depends on the site, so we quote after a free site walk rather than guessing on the phone. The biggest drivers in Arlington are usually soft ground, buffers and permits, size of the property. You get a written number with inclusions and exclusions spelled out.
When is the best time to schedule excavation in Arlington?
+
Excavation in Arlington 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.
What jobs has DirtRaptor done in Arlington?
+
Among others, we cleared leaning alders from a horse pasture and pulled a large Douglas fir root ball and stump, leaving the ground graded and usable. Both are on our Projects page with photos.
Do I need a forest practices permit to clear trees on my Arlington acreage?
+
Sometimes. Cutting a few trees for a home site usually falls under local clearing rules, but larger timber harvests can trigger a Washington DNR forest practices application. We help you figure out which applies before work starts.
Do I need a permit to excavate on my property?
+
Often yes. Snohomish County and most cities require a grading permit once you move more than a threshold volume of earth, and separate permits apply near critical areas, steep slopes or wetlands. Foundation work is permitted as part of the building permit. We can tell you which apply during the site walk.
