Road transportation in the Four Creeks/Tiger Mtn area

A number of years back, FCUAC decided to capture comments about transportation in the area.  Shortly after, this data was projected so that it could be used on maps.


This is a list of transportation locations in the FCUAC service area.  It consists of points (intersections), lines (roads and road segments), and polygons (areas).  With some minor exceptions, every item is mapped.


Four Creeks has a program that builds maps for residents and communities.  One set of those maps are focused on transportation.

Some of the maps in the set are:

  • King County Roads priorities
  • FCUAC interests
  • Transportation (roads, bikes, transit, bike, pedestrian)
  • Corridors
  • Special area focus

All the transportation maps are on the Atlas site in the Maps>Gallery under the Thematic group. [broken link; add map links to this page]

King County Roads visit to Four Creeks

King County Roads visits the FCUAC November 2018 meeting

King County Roads Strategic Plan (2014): The Strategic Plan includes a detailed discussion of the financial constraints faced by King County Road Services, their effect on our ability to maintain the road system, and the strategic priorities that guide our investment of Roads’ limited funds.

King County Roads 2016 Transportation Needs Report (2016): The TNR is a list of improvements to serve unincorporated King County’s transportation needs, projected to the year 2031. It is a component of the King County Comprehensive Plan.

Regional Transportation System Initiative (2017-2018): This partnership between the Sound Cities Association, King County cities, the Puget Sound Regional Council, the Washington State Department of Transportation, and King County identified the critical connecting roads that comprise the regional road network and their unmet maintenance, operations, and capital needs. The regionally significant roads include SE May Valley Rd, Issaquah-Hobart Rd SE, and SE 128th St. The final report and a large format regional road network map are at the link below.

Regional Transportation Service Initiative (RTSI)

Regional Arterial Network (RAN)

In 1998-1999, King County proposed designating certain roads as part of a Regional Arterial Network, and then create a funding mechanism that included all jurisdictions. Roads like Issaquah-Hobart Rd would have been included. That mechanism was envisioned to more equitably fund road use, recognizing, city residents use the RAN but the cities make no contribution to its funding.

The proposal didn’t initially get enough traction to move forward, however, in 2016-2017, the Regional Transportation Services Initiative (RTSI) involving all jurisdictions in King County began.

As of early 2018, there was insufficient consensus amount leaders to move forward.

KUOW Radio program on rural roads in King County

Broadcast in April, 2015, it does a good job of showing some of the causes of the rural road situation. In a sense, the proposal is similar to the RAN proposal, although the KUOW broadcast focuses on the creation of a funding district.

Issaquah-Hobart Rd/Front St corridor study

A joint study by Issaquah and King County of the section of Issaquah-Hobart Rd corridor from Gilman Blvd to SR-18

The study was reported to the Issaquah Committee of the Whole on April 24, 2018

May Valley Rd east truck traffic

Valley residents engage with King County Roads regarding probable impacts to the eastern portion of May Valley Rd due to the Issaquah decision to ban certain sized trucks from Front Street.

There was an increase in truck traffic on the SR-900 and May Valley Rd route that resulted from the Issaquah decision.
