Shoreline · King County
Excavation Contractor in Shoreline, WA
Foundation digs, footings, utility trenches and building pads in Shoreline, dug to spec by an owner-operated crew with its own excavators and dump trucks. Serving Richmond Beach, Innis Arden, Richmond Highlands and Echo Lake and the rest of Shoreline.
What the ground is like for excavation in Shoreline
Upland plateau falling steeply west to the Sound at Richmond Beach and Innis Arden, cut by ravines like Boeing Creek. 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.
Glacial till over the uplands, with sand and silt layers and landslide hazard areas on the western bluffs. On a Shoreline 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.
Puget Sound shoreline, Boeing Creek, Thornton Creek headwaters, McAleer Creek and Echo Lake carry critical-area buffers. 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 Shoreline
New home and ADU foundations
Footprints for new houses, ADUs and garages on infill and teardown lots around Richmond Beach and Innis Arden, dug to the elevations on your plans and ready for forms.
Hillside cuts and daylight basements
Excavation on sloped Shoreline 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 Shoreline 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 Richmond Highlands to the edge of Shoreline.

Permits & Rules
Excavation permits and utility locates in Shoreline
Inside city limits, the City of Shoreline handles building and grading permits. Properties outside city limits fall under the King County Department of Local Services. 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 Shoreline
We do not publish flat prices because no two Shoreline sites are the same. These are the things that move the number most here.
Slope and access
Steep Shoreline lots take smaller machines, more careful staging and sometimes engineering, which adds time compared with flat, open ground.
Soft ground
Where Shoreline 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 Shoreline's rivers, creeks, lakes or shoreline can need permits and limits on where machines go. That affects scope and schedule more than price.
Haul-off and disposal
How much material leaves the site, and what it is, drives cost. Our own trucks keep that predictable on Shoreline jobs.
When to schedule excavation in Shoreline
Excavation in Shoreline 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.
Shoreline'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 Shoreline
Shoreline sits just north of Seattle, with Puget Sound bluffs on the west side and established neighborhoods across the middle. The new light rail stations are bringing a wave of redevelopment and townhome infill.
We dig foundations, ADU and garage footprints, septic and utility trenches, and building pads across Richmond Beach, Innis Arden, Richmond Highlands, Echo Lake, North City, Ridgecrest, Ballinger and Parkwood. Mostly 1950s and 60s ramblers, larger view homes on the west side, and new townhomes near the light rail stations and Aurora.
Our trucks run in and out on I-5, SR 99 (Aurora Ave N), NE 175th St and NE 145th St, so spoil haul-off and fill delivery happen on our schedule instead of a subcontractor's.
We also do excavation nearby in Mountlake Terrace, Lake Forest Park, Brier and Edmonds. See everything we do in Shoreline, read our full guide to excavation, or browse all service areas.

Questions
Excavation Contractor in Shoreline: FAQs
What kind of soil will you hit digging in Shoreline?
+
Glacial till over the uplands, with sand and silt layers and landslide hazard areas on the western bluffs. 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 Shoreline?
+
Inside city limits it is the City of Shoreline. Outside them it is the King County Department of Local Services. 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 Shoreline 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 Shoreline?
+
It depends on the site, so we quote after a free site walk rather than guessing on the phone. The biggest drivers in Shoreline are usually slope and access, soft ground, buffers and permits. You get a written number with inclusions and exclusions spelled out.
When is the best time to schedule excavation in Shoreline?
+
Excavation in Shoreline 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.
Can you remove the old foundation and trees for a Shoreline townhome project?
+
Yes. We demolish the existing house, remove the foundation, take out the approved trees, protect the ones staying and excavate for the new building, all on one schedule.
Do you work on Richmond Beach and Innis Arden bluff properties?
+
Yes, with care. Bluff properties need controlled drainage, light equipment near the edge and often a geotechnical review.
How long does a foundation excavation take?
+
A straightforward residential foundation on an accessible site is typically one to three days of machine time. Add days for haul-off, difficult access, over-excavation or weather. We give a realistic window with the quote rather than a best case.
