Bothell Riverside Cleanup Site

The state Department of Ecology is ready to formally adopt a cleanup plan and related report and study by the City of Bothell for a cleanup the city completed earlier this year.

Public comment period

Ecology seeks public comment on the documents Oct. 20 through Nov. 20, 2017.

Even though City of Bothell removed petroleum-contaminated soil at a property it acquired for its Downtown Revitalization Plan, the state’s cleanup law requires Ecology’s formal adoption of the plan. Bothell's two-acre parcel lies within the realigned State Route 522 (Woodinville Drive) at NE 180th St.

The City removed the soil at part of the site that once contained a gas station. Bothell is also pumping and treating groundwater contaminated by solvents under another part of the site.

Bothell signed a cleanup agreement with Ecology, called an agreed order, in 2009 that describes the cleanup process for the site. The City has received approximately $500,000 in Ecology grants to offset the cleanup costs. The funding, called Remedial Action Grants, helps local governments clean up contaminated sites for redevelopment.

We want your comments

We're looking for your comments on: A feasibility study and cleanup action plan for solvent-contaminated groundwater at the other portion of the site are under development. Ecology will seek public comment on them at a later date.
