SEATTLE C.A.P.
Lot Size: 45 acres Location: Seattle, WA Project Type: Master Plan
Project Narrative: “C.A.P. proposes to insert topography and public park space into the chasm created by Interstate 5” A narrow swath of land between Lake Washington and Elliott Bay is situated in the remote upper northwest corner of the United States – here sits the City of Seattle. Populated by Douglas fir and Red cedar trees until settlers started turning the isthmus into a fast growing metropolis just over 150 years ago. The first major industry in the city, logging, was successful in turning the tall forests into an urbanized landscape. As the growing city met topographical challenges, the topography was simply removed, relocated or filled-in to create a more suitable environment for euro-centric city building. This approach to city building was so successful that by the mid-1900’s the city of Detroit, MI had more trees and greenspace downtown than Seattle, WA. The Seattle Commons took an underutilized portion of the city within close proximity of the downtown core and turned it into a Central Park-esque feature in the middle of proposed development on the periphery. Despite generous support from Paul Allen to create the Seattle Commons as a public amenity to balance out the proposed development, the City of Seattle said no thank you to a 45 acre downtown park. 25 years of impressive growth have built-out South Lake Union as well as many other neighborhoods around the city. As the urban core densifies opportunities for significant public green space downtown are becoming difficult to imagine. Interstate 5 occupies an immense swath of land through downtown Seattle, slicing the isthmus in two pieces with the cut occurring along the edges between the International District/Downtown Core/South Lake Union to the west and First Hill and Capitol Hill to the east. Minor attempts to connect the city with itself are tenuous at best. The C.A.P. proposal solves multiple issues, our growing city can thrive from the complexity of the challenges facing its citizens. We can have a beautiful public park, a destination convention center, a downtown sports arena and affordable housing. Each of the neighborhoods have multiple opportunities to tie the city back together at large and small scales. Focus on the public amenities, public input and evolutionary process that the C.A.P. infrastructure supports will allow the development of the concept over time.

Growing With the Population Seattle is one of the fastest growing cities in America. With limited land to expand on, we’ve built vertically for housing and office space, but we’re running low on potential places for green space. Seattle CAP would provide the city with much needed amenities by utilizing the space above I-5.
