Green to Cedar Rivers Trail
PROJECT UPDATE - King County Parks is proposing to develop a 2-mile-long section of the Green to Cedar Rivers Trail (G2C Trail) to connect SE Kent-Kangley Road to the Black Diamond Open Space. This project is part of a larger vision to improve mobility and access to high-quality regional trails for people of all ages and abilities to enjoy. King County Parks recently created a public input survey to hear from community members. Click here to view results.
The Green to Cedar Rivers Trail is currently in design. Once completed it will be a north-south connection for cyclists, pedestrians and equestrians, weaving through the best of an exceptional landscape connecting south King County communities to rivers, lakes, creeks, and natural areas. This 11-mile trail will improve a section of existing soft-surface trail to a full standard shared-use trail and eventually extend it, connecting the Cedar River Trail to Flaming Geyser State Park on the Green River.

The Green to Cedar Rivers Trail, much like all of our Regional Trails System trails, is a work in progress requiring constant management and upkeep. We always welcome constructive suggestion about trail maintenance, or safety from our users. Be sure to let us know if you see something on the trail that you think we can improve.
A trail from Seattle to Flaming Geyser State Park – The vision for the trail was originally proposed in the 1992 King County Regional Trails Plan as the “Maple Valley-Flaming Geyser Trail”. The County has been in discussion about the trail vision with the cities of Black Diamond, Maple Valley, and Covington, as they are primary stakeholders within the corridor. In 2012, King County conducted a feasibility study for the trail corridor that identified key opportunities and constraints for future development. Funding for the preliminary design of the entire corridor and construction of the North Segment was proposed as part of the 2014-2019 King County Parks, Trails, and Open Space Replacement Levy.
Why is King County developing the Green to Cedar River Trail? – The Green to Cedar River Trail is part of a larger vision of mobility and access to all residents of King County. Not only does our Regional Trails System provide a connection between locations, it also connects people to healthy living, recreational opportunities, mental health, stress reduction and much, much more.
A trail for the community – By 2018, design of the 3.3-mile north segment portion of the paved trail is expected to be approved, and in the years following, the southern portion of the trail along Black Diamond to Flaming Geyser State Park is anticipated.
Design and construction of each portion will continue to adhere to the agreements made during the early planning phase to provide a safe, multi-use regional trail for bicyclists, pedestrians, joggers, skaters, strollers, wheelchairs, and users of all ages and abilities.
Project Information by Segment:
Location: 3 miles beginning at the Cedar River Trail to SE Kent Kangley Road
Project update: King County Parks is moving forward with this important trail project that will upgrade the Green to Cedar Rivers Trail to Regional Trail standards, including a 12-foot wide paved trail. This upgrade will make the trail accessible for all ages and abilities while connecting communities, inspiring healthy living and supporting a sustainable future. The north segment of the trail is currently a 10-foot wide gravel trail that is accompanied by a narrower side trail in some sections of the corridor.
SEPA was completed in summer 2018. The timeline for final design and construction of the north segment is not yet determined, pending funding and permitting.

South Interim Trail
Ravensdale Fish Barrier Removal
The contractor will complete the majority of the work on the Ravensdale fish barrier removal project at SR 169 and the Black Diamond Open Space by the end of September 2022. The new bridge at SR 169 was completed early this year. More recently, a new pedestrian bridge along the Green to Cedar River Trail was installed after the existing culvert within the railroad embankment was removed. In total, three fish barriers (culverts) were removed and the stream channel was improved for fish habitat. Water is once again flowing within Ravensdale Creek as the contractor preps the project site for landscape planting and restoration, which will begin in October. This project will be complete by December 2022.
