Bothell Demolition on Hills and Creeks

Bothell is a city of hills, creeks and two counties, and demolition contractors here have to plan for all three. Glaciers cut north-south channels that now form Bothell's seven hills, and the highest point, Nike Hill, reaches about 510 feet. The city straddles King and Snohomish counties; in 2020, 60 percent of its 48,161 residents lived on the King County side.

Slopes and landslide areas

Wikipedia notes that some areas south of the Sammamish River are prone to landslides. On sloped lots, demolition is not just knocking a house down. Basement walls, rockeries and retaining walls can be holding soil in place, and removing them without a plan can cause the hill to move. We identify anything structural on the slope, ask whether a geotechnical report exists, and leave walls in place when they need to stay until the new foundation is built.

Creeks and erosion control

Most of the city drains to the Sammamish River or its tributaries, North Creek and Swamp Creek, and part drains through the Juanita Creek basin to Lake Washington. A bare demolition site near any of these creeks can put sediment in the water quickly during a fall storm. We use silt fence, rocked construction entrances, catch basin protection and covered stockpiles, and we time the work to the weather when we can.

Permits and the Clean Air Agency

The City of Bothell issues demolition permits through its permit center for both the King and Snohomish county parts of town. Before demolition, the side sewer is capped and the water service is cut under the serving utility's rules; parts of Bothell are served by special districts rather than the city, so we confirm the provider first. The Puget Sound Clean Air Agency covers both counties, which means an AHERA asbestos survey, a demolition notification for any structure over 120 square feet of roof area, and a 10-day wait after filing.

A rebuilt downtown

Bothell incorporated as a town on April 14, 1909. Its $150 million downtown redevelopment program began in 2010 with the realignment of State Route 522 at its intersection with the Bothell-Everett Highway, completed in 2013. Around that rebuilt core and the University of Washington Bothell campus, older houses and small commercial buildings continue to come down for new housing. We handle residential teardowns and small commercial demolitions, including slabs and parking areas.

Bothell Questions

Can you demolish a house on a steep lot in Bothell?

Yes, with planning. We identify walls and foundations that may be holding the slope, ask for any geotechnical report, and leave critical walls until the new foundation is in.

Does it matter which county my Bothell house is in?

The city permit applies on both sides, and the Clean Air Agency covers both King and Snohomish counties. The main difference is often which water and sewer district serves the lot.

How do you protect North Creek and Swamp Creek?

With silt fence, a rocked entrance, catch basin protection and covered stockpiles, kept in place until the site is stable.
