Draft Trail Master Plan and Environmental Impact Statement released! 

King County is planning 16.7 miles of new regional trail that will connect the Eastside like never before and provide the cities of Renton, Bellevue, Kirkland, Woodinville and Redmond with new opportunities for non-motorized recreation and transportation.  The opportunities are many, whether it is expanding our transportation options, creating economic and cultural opportunities, protecting natural resources, maintaining access to scenic vistas, or providing recreation around the beautiful Northwest. Alternatives under consideration in the Draft Master Plan and Environmental Impact Statement (EIS) include placement of the trail on or off of the existing railbed in the corridor, with consideration of the impacts and benefits of each alternative. 

We welcome your feedback and engagement as we move into the next phase of this exciting project. For ways to review the document and provide comments please see below.

The Eastside Rail Corridor is part of a 42-mile rail line once owned by Burlington Northern Santa Fe Railway Company (BNSF). When BNSF decided to sell, King County joined with other partners to preserve this valuable corridor and place it in public ownership. 

The ERC is owned and managed by King County, the cities of Kirkland and Redmond, Sound Transit, and Puget Sound Energy. These owners work together through the Regional Advisory Council to maintain a collaborative, regional planning process for the ERC, with the goal of achieving connectivity and multiple uses in the corridor.
