Bridge and Trestle Program
There are 86 bridges and trestles in King County's Regional Trails System, including 15 spans that are now more than 90 years old. King County Parks inspects, monitors load rates, repairs, and replaces these structures on an on-going basis.
in our 2014-2019 Levy we committed to repairing or replacing 14 bridges and trestles on our regional trails. By the end of 2016 we will have completed repairs and replacements on 10 of these 14 bridges including:
- A major rehabilitation on the 400-foot Tokul Creek bridge
- Replacement of the Snoqualmie Valley Trail #40 bridge near Mt. Si Golf Course
- Significant stringer and cap repairs to the numerous trestles along the Snoqualmie Valley and Cedar River Trails
- A significant scour repair project on the Sammamish River Trail
For the remainder of the levy, we will continue our inspection program, as well as completing at least 4 more repairs and replacements, including:
- Replacement of the trail bridge that leads into Remlinger Farm near Carnation
- Design of a replacement structure for the #2 bridge on the Preston-Snoqualmie Trail (near Lake Alice Rd.)
- Tolt-MacDonald Park Additional Suspension Bridge Repair
Burke-Gilman Trail - Lake Forest Park Improvements

Derby Creek Flood Reduction and Habitat Enhancement
This project will alleviate seasonal flooding of the Northshore Athletic Fields and remove two fish barriers by reconstructing approximately 800 feet of sediment-laden stream channel and replacing failing, undersized, fish barrier culverts, one under the Sammamish River Trail and another in the athletic fields. Similar stream channel reconstruction has already occurred in Derby Creek upstream. This project will complete the downstream portion of Derby Creek, connecting it all the way to the Sammamish River.
The project is currently in design, which is funded in part by the King County Flood Control District. King County Parks is pursuing additional grants and partnerships to fund construction of the project in 2019 or 2020.Project Manager: Lindsey Miller
Dockton Park Dock Rehabilitation

East Lake Sammamish Trail
King County Parks is initiating the design and construction of a one-mile segment of the Foothills Trail (formerly known as the Enumclaw Plateau Trail) along right-of-way owned by King County Parks. The trail segment begins at 252nd Avenue South, just outside and south of Enumclaw, and continues along a former railroad route to its terminus just north of Mud Mountain Road. King County Parks is working with the Cities of Enumclaw and Buckley to construct a bridge across the White River to connect both sides of the Foothills Trail.
King County Parks completed Phase I in 2010 of Foothill Trail development, constructing a soft surface trail on a one-mile segment of the trail from 252nd Ave S to just north of Mud Mountain Road near Enumclaw. Phase I also included improving the crossing at 252nd Ave S and installing a new pedestrian footbridge over a small stream that bisects the trail.

Maury Island Natural Area Remediation
King County Parks is coordinating with Washington State Department of Ecology to clean-up contaminated soil at Maury Island Natural Area. Air pollution from the Tacoma Asarco smelter settled on parts of King, Pierce, Kitsap, and Thurston counties, creating the Tacoma Smelter Plume. High concentrations of arsenic and lead from the smelter operations have been found in the Natural Area.
