Downtown Contaminated Soil & Groundwater Clean Up
Project description
This project is a component of Bothell's Downtown Revitalization Plan and is identified in the Capital Facilities Plan as T47. The environmental assessment and cleanup of several contaminated downtown Bothell city-owned properties needs to occur prior to their redevelopment. Since early 2008, the City has implemented environmental assessment efforts which entail conducting historic research and field investigations aimed at determining the presence, nature and extent of contamination in soil and/or groundwater on the various properties. This assessment work was followed by cleanup work beginning in summer 2010.
Contaminated parcels
Four contaminated parcels lie along the pathway of the new Crossroads roadway alignment. These are under Agreed Orders with the Department of Ecology, and one is also under a Cooperative Agreement with the U.S. Environmental Protection Agency (EPA). The Ultra Cleaners site is also under an Agreed Order. In the northern part of downtown, the City cleaned up another contaminated property in the area formerly occupied by the Northshore School District’s (NSD) Bus barn and transportation/maintenance facility.
Grant funding & assistance
The City has secured some grant funding and assistance to perform this work, including:
- A $3,520,000 Remedial Action Grant from the Department of Ecology for assessment and cleanup of the four Agreed Order sites (Bothell Landing, Bothell Riverside, Bothell Paint & Decorating, Bothell Hertz, and Bothell Ultra Custom Cleaners). Ecology will pay for 50% of eligible costs incurred by the City up to $3,520,000.
- A $200,000 Brownfields Cleanup Grant from the U.S. Environmental Protection Agency’s (EPA) to clean up the Bothell Landing site.
- The King County Brownfields Program also continues to assist the City by conducting environmental investigations to better understand groundwater impacts caused by former dry-cleaning businesses in the downtown area. This work was funded by an EPA Brownfields grant.
