October 2014
The design team is working with our partners at the University of Washington to complete construction documents for bidding this winter.

The final design development plan was presented at the Multi-Use Trail project's final public meeting on February 27, 2014. (See presentation below.) Thank you to those who have participated in the public process for the project.

The multi-use trail was identified in the Arboretum master plan that was adopted in 2000. The trail was identified as a way to enhance the visitor experience of Washington Park Arboretum. Intended for use by both pedestrians and bicyclists, the curving path is designed to preserve vegetation and control speed.

The Berger Partnership was awarded the design contract after Parks conducted a Request for Proposal (RFP) and interview process. Construction is anticipated to commence in 2015.

This project initially provided scoping and conceptual design for a redeveloped North Entry to Washington Park Arboretum and a multi-use trail from the intersection of East Madison to the North Entry and the Montlake and University neighborhoods beyond. The Consultant Selection Committee recommended that the Berger Partnership be hired to provide design services for the project and Parks moved forward with that recommendation.

Meetings for the design of the North Entry and Multi-use Trail were held in 2011. The community provided input to assist the designers in developing a preferred alternative. For meeting presentations and notes please see below.

In June 2013 City Council approved $7.8 million from WSDOT to fund implementation of the multi-use trail, which does not include the North Entry Project. The Arboretum Botanical Gardens Committee held a well attended press conference to announce this funding in January 2013. Final design and permitting will take place in 2014 and construction is expected to start in 2015.

Project Description

This project provides a multi-use trail from the intersection of East Madison through the arboretum to the intersection of Foster Island Road and Lake Washington Boulevard. The city received $7.8 million dollars from Washington State Department of Transportation. The Berger Partnership was awarded the contract design contract after an RFP and interview process was conducted.

The master plan for renewing the Washington Park Arboretum was adopted by City Council and the University of Washington Board of Regents in May 2001. The University, City and the Arboretum Foundation are working together to continue implementing the master plan.
