228th St SE/SR 9 Area Projects

The projects listed below were completed as part of a 2005 agreement between King and Snohomish counties related to the construction of the Brightwater Wastewater Treatment Plant. The agreement secured $70 million - provided by King County - to construct community assets in Snohomish County.

The projects included sidewalks, bike lanes, three county parks, land for a regional trail, the construction of other trails, a variety of habitat restoration projects, and the Brightwater Community Resource and Education Center.

At a November 2013 ribbon-cutting ceremony, Snohomish County residents and officials celebrated the completion of the projects with a ribbon-cutting ceremony at Miner's Corner Park, at the corner of 228th St SE & 45th Ave SE.

Speakers included Snohomish County Executive John Lovick, County Councilman Dave Gossett, Public Workjs Director Steve Thomsen, and Parks Department Director Tom Teigen.

Snohomish County Public Works constructed sidewalks and bike lanes along the north and south sides of 228th Street SE, between State Route 9 and 39th Avenue SE. Construction was completed in 2013.
