Landscaping in the King County RIght-of-Way

King County Parks recommends the use of native plants and plant types specified in the Regional Trails System Development Guidelines, Landscape Characterization Study. Native plants provide many benefits: they do not need fertilizers, herbicides, pesticides or watering, thus benefiting the environment and reducing maintenance costs. Please visit King County's GO NATIVE website to learn more about native landscaping.



Project Summary

The East Lake Sammamish Master Plan Trail (ELST) project includes design and construction of an alternative, non-motorized transportation corridor and a multi-use recreational trail along 11 miles of the former Burlington Northern Santa Fe (BNSF) railroad corridor on the east side of Lake Sammamish, from Redmond to Issaquah. The trail will provide access to recreation, employment and retail in the cities of Redmond, Sammamish and Issaquah.

The ELST is the missing link in a 44-mile urban regional trail system linking Seattle to the hub of East King County and on to the Cascade Foothills.

This project has developed in two stages:
Interim Use Trail and Resource Protection Plan
The Interim use Trail, which was completed in 2006, originally extended south from NE 70th Street in Redmond to Gilman Boulevard in Issaquah and features a crushed gravel surface.

Master Plan Trail
The ELST is being constructed in phases as funding allows. Construction includes a 12-foot-wide asphalt trail with two 2-foot soft surface shoulders and two 1-foot clear zones on each side of the trail. Additionally, construction includes; retaining walls, improved intersections, improved drainage systems, fish passable culverts, bollards, fencing and other trail amenities. The Master Plan Trail also includes plans to construct a total of 3 parking lots (2 parking lots with restrooms) for trail users; NE 70th St in Redmond, Inglewood Hill in Sammamish and SE 33rd St in Sammamish.

Segment Details

North Sammamish Segment (187th to Inglewood Hill Rd.) 2.6 miles
Redevelopment of the North Sammamish segment of the East Lake Sammamish Trail (ELST), from NE 187th St. to Inglewood Hill Road, will begin April 2014.  Safety is King County’s top priority. Due to the extensive amount of work, steep topography, and limited access, the entire trail segment will be closed for approximately one year. Trail safety and accessibility will be improved with a new 12-foot-wide paved corridor with two-foot soft surface shoulders on each side with enhanced intersections, open sightlines, and improved drainage.
Funding for the ELST North Sammamish segment is provided by the 2008–2013, voter-approved Open Space and Trails Levy (Proposition 2; August Primary Election 2007) and grant funding provided by the federal Surface Transportation Enhancements Program and the state Washington Wildlife and Recreation Program.
