Aubrey Davis Park Master Plan

WSDOT/City of Mercer Island

Mercer Island, WA

Aubrey Davis Park is a 2.8-mile long park along I-90 that is primarily owned by the Washington Department of Transportation (WSDOT) and managed by the City of Mercer Island. The park consists of the Park on the Lid, the Mountains to Sound Greenway Trail, the Boat Launch, and the Greta Hackett Outdoor Sculpture Gallery which are all part of Aubrey Davis Park. The purpose of the master planning process was to establish a long-term vision for the amenities, trails, and open space areas within park limits. The Master Plan was divided into three main categories: Vegetation Management, Trail Improvements and Amenity Improvements. The master plan provided recommendations for vegetation management to maintain the park’s natural character and longevity into the future. Master Plan recommendations for Trail Improvements were primarily limited to re-establishing sight-lines and clear zones along the existing Mountains to Sound Trail, renovation of the trail to the east of the Town Center due to disturbance from the King County Sewer Upgrade project, improving safety for all trail users and integrating wayfinding into the corridor. Amenity improvements for the park were focused on user safety and ADA access improvements to existing park elements. The Mercer Island Arts Council drafted a vision and core tenets to guide how art could create and maintain a sense of place in Aubrey Davis Park. HBB lead a team of consultants through this master planning process, helped develop prioritization criteria and provided rough order of magnitude cost estimates to help understand costs associated with proposed improvements. Master planning process was summarized in a master plan report.
