The trail section under construction will be closed to trail users, and construction on the two phases will overlap for approximately 12 months.
- 29 new retaining walls to provide slope stability and reduce the trail footprint, resulting in less impact on environmentally sensitive areas and adjacent residents.
- 10 reconstructed intersections with improved sight lines and safety features like concrete warning bands, bollards, striping and consistent signage. Warning bands provide a visual and textural difference from the paved trail’s surface and along with improved signage, indicate an intersection is 75-feet ahead.
- 5 new rest stops for trail users to sit and enjoy views of Lake Sammamish and the surrounding area.
- Approximately 700 new native trees and more than 11,000 shrubs providing erosion control, providing increased visual and aural screening of East Lake Sammamish Parkway, wildlife protection and habitat connectivity, and a continuous park like setting along the corridor.
- Over 6,000 linear feet of new chain link fence, installed for safety above steep slopes.
- Over 3,500 linear feet of split rail fence to protect and delineate critical natural areas.
- Over 600 linear feet of guard rail to protect and separate the trail from vehicles.
- Almost 1.5 acres of wetland, buffer, and shoreline mitigation area restored to increase fish and wildlife habitat and improve biological diversity.
- Features like habitat logs and brush piles as well as a variety of native plant species that will create multiple vegetation strata as they mature.
- Improved storm water conveyance systems along and across the trail to ensure they can accommodate a 25-year storm event.
