About the 4C Program

In preparation for major construction in the Center City area, SDOT has developed the Center City Construction Coordination Program. The acronym is 4C, and we mean it to signal our intention to foresee challenges and issues rather than just be reactive. This program was established to coordinate and sequence major construction projects in a way that maintains a vibrant, accessible and functioning Center City.

Helping the 4C Program succeed is a plan to implement 25 improvement projects that remove physical choke points to downtown so that transit and freight can move better. These projects support growth, help mitigate Viaduct construction impacts and complement the 4C Program. To learn more visit our Center City Access Strategy Web page.

SDOT is doing everything possible to keep Seattle's central core vibrant and accessible as an impressive array of projects become reality.

Specific aspects of the 4C program are:

Construction Scheduling
The City of Seattle has not invested in major infrastructure for 40 years, but that is changing. Over the next 10 years billions of dollars are being invested to create a 21st century transportation network. We are reconnecting our streets so that transit, trucks, bikes and cars can move better, adding alternatives to driving, such as light rail, streetcars and monorail, and replacing damaged structures like the Alaskan Way Viaduct. Schedule management is key, because not all projects are run by the City. Some are SDOT's alone, some are managed by an outside agency, and some are being accomplished in partnership with three to four other agencies.

As projects move into construction stages, the schedule will be more detailed so that you those along construction routes can find out what will be happening. The schedule is useful for planning and to let us know how upcoming construction will affect you.

Right-of-Way Permitting Program
In order to maintain mobility in the Center City area while major projects are under construction, we are aggressively managing and anticipating demand. SDOT has developed new tools that improve the City's ability to plan, coordinate and communicate use of our streets and sidewalks.

To date most attention has been on the pending transit tunnel closure. The program will expand and shift as other transportation projects progress. If you are planning to build, invest, or begin tenant improvements in the next five years in Center City Seattle you should contact SDOT immediately.

We must also consider sidewalk uses. Sidewalks will be monitored to confirm current permitted uses like sidewalk cafes do not cause situations like overcrowding. To find out more read our Frequently Asked Questions . To see which streets and sidewalks are affected by the new permitting restrictions view our Transit Emphasis Street Map.

You may also learn more about our Right-of-Way Management Program which includes ten projects focused on providing the tools and processes necessary to achieve our vision for Right-of-Way Management.

Options to Driving Alone
SDOT has partnered with the Downtown Seattle Association (DSA) and Metro King County to create the Urban Mobility Group. This group works personally with businesses to customize a program that gets you and your employees into a carpool or onto the bus. These programs can even reduce your tax burden. If you are not familiar with the programs visit www.urbanmobilitygroup.com to learn more.

Partnerships
Soon to open is "The Transportation Connection" - an outlet for commuters and other downtown travelers. Located right downtown in the Rainier Tower for easy access, Metro will sell bus passes and give out schedules, and the Urban Mobility Group and the 4C Program will have offices there.

More information coming soon.

Communication
Key to a successful program is communication. We have developed a comprehensive Communications Plan. Each major project already has its own extensive community outreach. We will not duplicate those efforts. Our plan fills the gaps and makes sure communication and construction coordination happens.
