Downtown Seattle core

One Center City

One Center City will bring together many communities, perspectives and partners to create a 20-year plan for how we move through, connect to and experience Seattle’s Center City neighborhoods. It is a public/private partnership between the City of Seattle, King County, Sound Transit and the Downtown Seattle Association.


One Region. One Plan. One Center City.

Seattle is one of the fastest-growing cities in the U.S. and much of that growth is happening in Center City.

How we get around is changing too. From more light rail to growing transit ridership to innovations like car sharing, and, someday, driverless cars.

To keep Center City moving and make sure that it continues to be a great place to live, work, and play, we’re planning ahead.

That’s why the City of Seattle, Sound Transit, King County, and the Downtown Seattle Association have come together to create the One Center City plan.

By working collaboratively, we will build an integrated plan that makes it easier to get around and enjoy Center City both in the near-term and over the next 20 years.
