Why noW?In Seattle, nearly 30 collisions occur on our streets every day.

People walking and biking are involved in collisions daily. Each year, more than 150 people sustain life-changing serious injuries and approximately 20 people die on our streets. People over age 50 are particularly vulnerable and have made up 70 percent of pedestrian fatalities in the last three years.

While Seattle is consistently recognized as a safe city, it’s time to do more to prevent crashes.

Seattle considers safety for people walking and biking a top priority since the likelihood of injury is nearly 100 percent if they are hit. And it’s important to note that safety projects benefit all travelers – people driving, biking, and walking. Through context sensitive engineering and thoughtful enforcement patrols, we will redesign our streets to reduce risk and improve conditions for everyone.

Vision Zero provides an opportunity to integrate our safety efforts by combining the street design recommendations of our Pedestrian, Bicycle, Transit, and Freight Master Plans with targeted enforcement patrols and educational outreach to address behavioral issues.

Now is the time to coordinate our safety efforts and commit to a goal of zero fatalities by 2030.

NEED TO MOVE

Existing electrical, gas, water, and sewer lines in the street are in conflict with the tunnel location and need to be relocated. The top of the tunnel would be within 1.42' of the top of the street elevation which does not provide enough cover for utilities.Sewer line would need to be lowered by 1-foot or more, and reconnect existing side sewers.

In the street: • Relocate sanitary sewer line • Horizontal excavation with

hydraulic ram tunnel (4 week closure) from Olympic Tower side.

Requires shoring and excavation of Olympic Tower • Waterproofing of tunnel on

exterior is not possible, so it will leak

Existing building: • Min. 24" for shoring and

underpinning around footings • Min. 18" thick walls at tunnel

and elevator walls to withstand footing loads

• 30' working clearance required for drill rig to install shoring
