Four Questions

Understand the proposal in 60 seconds

Question 1

What's the building?

The Arch — spanning 705 Pike Street and 800 Pike Street. 435,000 square feet of convention space between Boren Avenue and 7th. The building you've walked past for decades, with the glass skybridge spanning Pike Street. Three blocks from Westlake Station. Eight blocks from Pike Place Market.

Question 2

Why is it empty?

The Washington State Convention Center opened a $1.9 billion expansion — the Summit — in 2023. Conventions moved there. The Arch hosts roughly 25 public events a year now, against operating costs it can't cover. The CEO has called the situation "fragile" and "scary." Reserves have dropped from $200M+ to $25M since 2022.

Question 3

What could it be?

Seattle Commons. The city buys the Arch and Seattle Center operates it as a year-round public commons — markets, maker spaces, performance venues, community programming, food halls, co-working, events. The SCC leases it back for the convention days it still needs.

Question 4

Why now?

The SCC can't afford to hold the Arch. The city solves the problem by actually running the building full. International convention bookings are in structural decline — the projections the Summit was built on no longer hold, and the window to act narrows with every reserve dollar spent. Sound Transit's Crosslake expansion just connected Bellevue and Redmond directly to this block.

The Argument

Activate the Arch 365 days a year

The convention center corridor — ten blocks of Pike Street between Boren and Pike Place Market — is the dead zone in downtown Seattle. The Cheesecake Factory closed. The Homewood Suites next door converted to AVIA Apartments because the visitor market couldn't sustain it. Three corners at 5th & Pike are vacant simultaneously.

The cause is the building. A 435,000-square-foot building with no public programming 250 days a year cannot sustain the street around it. Every store that closes makes the next lease harder. Every empty corner signals to the next tenant: don't.

Activate the Arch 365 days a year. Not a new building. Not a demolition. Turn a building that hosts 25 public events a year into a public asset that operates every day — markets, performances, maker spaces, food halls. The same building, used differently.

Pike Place Market proves the model. Over a century of daily activation sustaining two blocks of the most valuable street-level retail in the Pacific Northwest. Seattle Commons extends that proof ten blocks east.

An empty convention center on one end. A 15-million-visitor market on the other. And between them, ten blocks waiting for the thing that makes streets work: people, every day, with somewhere to go.

The Commons

Where Seattle meets itself

The Arch sits three blocks from Westlake Station, the light rail node connecting SeaTac Airport to Capitol Hill. Eight blocks from Pike Place Market. On the transit corridor that links the ferry terminal to every hotel, stadium, and neighborhood in the city. When the Crosslake extension opened, the Eastside gained direct rail access to this block.

The Commons doesn't compete with anything around it. It's the reason to stop.
