Image for Sounder South Parking & Access Improvements Design-Build Project Management Rendering by Mithun

Due to a steady increase in ridership on Sounder South and anticipated growth, Sound Transit embarked upon the Sounder South Access Improvement Project, with the goal of not only expanding capacity, but also improving the rider experience. As part of this project, Sound Transit plans to provide structured parking at the Puyallup, Sumner, Kent and Auburn stations. 

The team of HNTB and Watry Design, Inc. were selected to provide procurement, preconstruction and construction management services for the design-build garages.

The team is working closely with Sound Transit to provide procurement and design support for the Puyallup Garage. This includes ensuring the structure’s design meets Sound Transit standards, adheres to building codes and follows parking industry best practices. 

The structure will feature 503 stalls and is being designed to fit within the context of downtown Puyallup. Pedestrian infrastructure upgrades include a covered bridge to safely escort passengers over heavily trafficked areas.

The Watry Design team will also be designing bridging documents and preparing the RFP for the Auburn and Kent parking garages.
