Waterfront Seattle 
Seattle, Washington
Client: ​City of Seattle
Partner: CH2M Hill

Waterfront Seattle is responsible for planning and designing a new dynamic public waterfront, including a surface Alaskan Way Boulevard connecting Seattle’s downtown east-west streets. The area will be transformed into a world-class public place with open space, new development, and public amenities after the elevated Alaskan Way Viaduct is demolished in 2015. Parametrix is leading the transportation effort, which involves working with City staff and the urban design team to provide facilities for vehicles, pedestrians, bicyclists, and transit. The transportation plan is exploring options to develop a flexible street space to accommodate different user groups during peak, off-peak, and weekend time periods.
