The Seattle Department of Transportation (SDOT) is a municipal government agency in Seattle, Washington that is responsible for the maintenance of the city's transportation systems, including roads, bridges, and public transportation. The agency is funded primarily by taxes that are supplemented by voter-approved levies from other sources; its budget in 2017 was $450 million. ^[1]

History

The Seattle Transportation Department was formed in 1996, as part of the re-organization and eventual dissolution of the Seattle Engineering Department. ^{[2] [3]} The division was renamed to the "Seattle Department of Transportation" in 2004. ^[4]

Administration and management

Director

The department is managed by the Director of Transportation, a position appointed by the Mayor of Seattle and confirmed by a majority vote from the Seattle City Council. The position is subject to re-appointment and re-confirmation every four years. ^[5]

Since 1997, nine people have held the office of Director of Transportation. ^[6] Greg Spotts was nominated in 2022 for the position. ^[7]

Funding

In 2015, SDOT had an adopted budget of $429 million. The largest portion of the budget, approximately $186 million, is allocated to major capital projects, including collaborations with regional and state agencies. ^[8]

Transportation levies

Much of SDOT's long-term funding comes from voter-approved funding levies and other taxes. In 2006, the $365 million "Bridging the Gap" levy was approved by Seattle voters, using property taxes and parking fees to fund nine years of transportation improvements. ^{[9] [10]} The levy was replaced in 2015 by the voter-approved "Move Seattle" levy, funded by a new property tax, that will provide $930 million over a nine-year period. ^[11]

Programs

Seattle Streetcar

SDOT maintains the citywide streetcar network, which consists of two lines, as of 2016 ^[update]: the South Lake Union Streetcar, opened in 2007; and the First Hill Streetcar, opened in 2016.

Transit funding

In addition to road funding, SDOT also provides funding for public transit improvements through partner agencies. The 2015 "Move Seattle" levy includes funding for expansion of King County Metro's RapidRide system into Seattle, replacing existing bus routes.

Cycling infrastructure

Since the passage of "Bridging the Gap" levy in 2006, SDOT has funded $36 million in bicycle infrastructure, including 129 miles (208 km) of bicycle lanes and sharrows, 98 miles (158 km) of signed bicycle routes, and 2,230 bicycle parking spaces. ^[12] A bikeshare system, Pronto Cycle Share, debuted in 2014 and was initially operated by a non-profit organization until it ran into financial issues a year later. SDOT took over operations until the system was shut down in early 2017. ^[13] It was replaced with a permitting system for private companies operating dockless bikeshare that launched in 2017. ^[14] The permitting system was expanded beyond its initial pilot to several companies with bicycles distributed across the city; ^[15] dockless scooter-sharing was allowed beginning in 2019. ^[16]

Autonomous vehicles

In November 2022, SDOT introduced a permitting system for autonomous vehicle operators in the city that would allow them to use public streets with a driver. Zoox, Nvidia, and Cruise have since begun testing their vehicles in the city. ^[17]

Facilities

As of 2015 ^[update], SDOT has an estimated $20 billion in transportation assets within the city of Seattle. It maintains 3,954 miles (6,363 km) of streets, 122 bridges, 609 stairways, 158 traffic cameras, 1,061 signalized intersections, and 29,073 curb ramps. The Urban Forestry division maintains over 41,000 street trees, as well as 110 acres (45 ha) of managed landscape areas. ^{[8] [18]}
