Excavation & Tree Service in King County
In King County, DirtRaptor works the north end and the Eastside every day, from Shoreline and Lake Forest Park through Bothell, Kenmore, Woodinville, Kirkland, Redmond, Bellevue and Sammamish to the Snoqualmie Valley. South King County jobs are taken on where the scope justifies the mobilisation.
The Ground
Working the ground in King County
Ridges and hills between Puget Sound, Lake Washington and Lake Sammamish, with the Sammamish, Snoqualmie and Cedar river valleys cutting through and the Issaquah Alps and Cascade foothills to the east.
Soils
Glacial till over most of the urban and suburban area, with outwash sands in places, soft valley alluvium along the rivers, and coal mine hazard areas in parts of Renton, Newcastle and Issaquah.
Water and buffers
Lake Washington and Lake Sammamish shorelines, salmon streams like Bear Creek, Little Bear Creek, Lyon Creek and Issaquah Creek, and the Snoqualmie floodplain all carry shoreline, stream or floodplain rules.
Trees
Large Douglas fir, western red cedar and bigleaf maple across established neighborhoods. Many King County cities, including Kirkland, Redmond, Sammamish, Lake Forest Park, Shoreline, Mercer Island and Seattle, regulate removal of significant trees.
Typical work here
Teardown and rebuild prep, ADU site work, permit-driven tree removal, drainage on till soils, steep-lot excavation, and rural work in the Woodinville and Snoqualmie Valley areas.

Grading & Drainage
Retaining walls, RV and equipment pads, and drainage correction that actually moves water away from the structure.

Cities
Cities we serve in King County
Woodinville
Woodinville is known for its wineries in the Sammamish River valley, but the hills around it are full of horse properties, wooded acreage and large-lot homes. Pasture clearing, driveways, drainage and tree work are all common here.
Kenmore
Kenmore sits at the north end of Lake Washington where the Sammamish River enters it. Much of the city is steep, wooded hillside above the lake and the Burke-Gilman Trail.
Kirkland
Kirkland stretches along the east shore of Lake Washington from Houghton up through Juanita and Finn Hill to Kingsgate. It has some of the strictest tree rules on the Eastside and a lot of high-value homes on tight or sloped lots.
Redmond
Redmond runs from the Sammamish River valley and downtown up onto Education Hill, Grass Lawn and the Overlake tech campuses. It mixes established neighborhoods with a lot of new construction.
Bellevue
Bellevue covers a lot of ground, from lakefront and Bridle Trails horse properties to the steep hillsides of Somerset and Cougar Mountain. High-value homes, steep slopes and a careful permit desk make planning the most important part of any job here.
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.
Lake Forest Park
Lake Forest Park is a heavily wooded city at the north end of Lake Washington with salmon creeks running through deep ravines. It is one of the most tree-focused cities in the region, and work here is mostly careful, selective and permit-driven.
Sammamish
Sammamish sits on a plateau between Lake Sammamish and the Snoqualmie Valley. It is mostly newer, larger homes among tall trees, small lakes and wetlands, and the city has strong tree retention rules.
Duvall
Duvall overlooks the Snoqualmie Valley, a broad farm valley with the river winding through it. Around town the work is rural: pastures, long driveways, barns, outbuildings and big trees.
Seattle
In Seattle, DirtRaptor mostly works the north end, from Lake City and Wedgwood to Greenwood and Ballard. Seattle lots are tight, access is often by alley, and the city has detailed rules for trees and steep slopes.
Issaquah
Issaquah sits in a valley ringed by the Issaquah Alps, with the Highlands and Talus neighborhoods climbing the hillsides. Work here often means steep ground, big trees and careful permitting.
Snoqualmie
Snoqualmie is the historic railroad town below the falls plus the master-planned Snoqualmie Ridge above it. The two halves have very different ground: floodplain in the old town and engineered hillside lots on the Ridge.
North Bend
North Bend sits at the foot of Mount Si where the forks of the Snoqualmie River come together. Rural lots, big trees and floodplain rules define most of the work.
Carnation
Carnation is a small farm town in the Snoqualmie Valley where the Tolt River meets the Snoqualmie. Farms, pastures and rural homes make up most of the area.
Renton
Renton runs from the south end of Lake Washington up into the Highlands, Kennydale and Benson Hill. It mixes older homes, new subdivisions and plenty of hillside lots.
Newcastle
Newcastle sits on the western flank of Cougar Mountain and grew from a historic coal-mining town into a city of hillside neighborhoods. Steep lots, big trees and old mine hazard areas are part of the work here.
Mercer Island
Mercer Island sits in the middle of Lake Washington, with high-value homes on wooded, often sloped lots. Tree rules are strict and access is often tight, so planning is everything.
Also serving Kent, Auburn, Federal Way, Burien, Tukwila, Maple Valley, Covington, Enumclaw, Black Diamond and surrounding unincorporated King County.
Timing
When to schedule work in King County
Across King County, the drier months from late spring into early fall are the best window for excavation, clearing and grading, when soils compact properly and machines leave the ground in good shape.
Floodplain ground in King County's river valleys is worked once high water has dropped, and work near salmon streams can be limited to set months.
Tree work, hauling and demolition run year round. Hazard trees are best handled before the fall and winter windstorms.
Permits & Rules
Permits in King County
Outside city limits, the King County Department of Local Services handles clearing, grading, building and demolition permits. Inside a city, that city's permit desk takes over, and rules on trees and critical areas vary from city to city.
Demolition falls under the Puget Sound Clean Air Agency, which requires an asbestos survey and advance notice for most structures. Every dig starts with an 811 utility locate at least two business days ahead.
Questions
King County FAQs
Who issues permits in unincorporated King County?
+
The King County Department of Local Services handles permits outside city limits. Inside a city, that city handles them, and King County cities vary a lot on tree and clearing rules.
Are King County tree rules stricter than Snohomish County's?
+
Often, yes. Several King County cities require permits and replacement trees for removing significant trees on private property. We confirm what your city requires before scheduling.
Do you work in south King County?
+
For larger scopes, yes. North King and the Eastside are our daily radius; further south we take on jobs where the mobilisation makes sense.
Who handles asbestos surveys and demolition notices in King County?
+
King County is covered by the Puget Sound Clean Air Agency. Most demolition needs an asbestos survey by a certified inspector and advance notice, and we line both up before scheduling.
