What's at risk
King County Road Services manages approximately 1,500 miles of county roads and 181 bridges that carry more than 1 million trips per day. The 250,000 residents of unincorporated areas receive roadway, drainage, shoulder, and right of way maintenance and operations services directly from King County. These systems are aged and deteriorating.
The total assessed property value in unincorporated King County fell by almost 40 percent after the recession from 2010 to 2013, and future growth in revenues is limited by state law.
The current Capital Improvement Program has shrunk significantly, now funding only a very small portion of needed maintenance and preservation of the road system.
Below is a map of bridges and roads listed in King County's Transportation Needs Report.

The funding gap
The Roads Services Division is supported by local property tax, gas tax and grant funding. Average assessed residence value in unincorporated King County fell by almost 40 percent after the recession from 2010 to 2013, and future growth in revenues is limited by state law.
Estimates show that it would cost $350 million annually over 10 years to fully address the current backlog of needs and bring the system into a state of good repair. Forecasts say the county will generate $90 million annually under the current revenue structure – a structural funding gap of $260 million a year.
