Seattle Parks and Recreation has approved a pilot project at Cheasty to test bike trails, including mountain bike trails, in natural areas.  The first trail design is at the schematic stage and is under review.   As a community we are committed to making the mountain bike pilot project successful and advocating for a long range plan and a comprehensive trail design.   A comprehensive trail design would include several mountain bike and pedestrian trails connecting east-west across the greenspace.  This would provide for a variety of experiences, including a variety of progression opportunities for youth in the neighborhood.


Key Objectives of Mountain Biking Trails Plan

  • Create trails that are fun and safe for a variety of skill levels.
  • Provide access to nature for the health and benefit of all who live in the area.
  • Connect surrounding neighbors that surround Cheasty with each other, and provide a place to meet each other in a positive setting.
  • Provide a local venue for youth programs in Seattle to teach mt. bike riding and maintenance skills, encouraging lifetime bicycle skills and habits.
  • Facilitate opportunities for local youth to engage in a healthy outdoor activity, reducing their dependence on sedentary pursuits.
  • Create active opportunities that families can enjoy together.
  • Displace ecologically and socially destructive human activities with restorative and positive human activities.
Bicycle Trails

Mountain bike trails are designed to integrate with the land and flow around existing natural features.

Trail Concept

The original concept design for mountain bike trails, called “Beacon Bike Park” was made  with the assistance of the Evergreen Mountain Bike Alliance (EMBA).  EMBA has built mountain bike trails throughout the state including at Duthie Hill in Issaquah and Swan Creek in Tacoma.  By virtue of its size, dense urban surroundings, and multi-use orientation, Cheasty Greenspace will be smaller, less technical, and geared more towards families and skill progression than many parks designed solely for mountain bikers.  Our design goal is to have a sustainable trail system carefully planned to challenge a range of users and skill levels in order to ensure generations of positive use.  The following draft schematic design is one of the original proposed designs that included a variety of trail types as well as descending trails.

Draft Concept of Bicycle Trails

Draft concept of mountain bike trails  including downhill trails, freeride trails and a progressive jumps and drops zone.

Single-track mountain bike trails generally have a 24″ wide trail bed, on native soil, and are designed using the existing contours of the space to maximize sustainability and minimize erosion.  We intend to build the trails through volunteer effort and with a careful focus on the restored natural area.  As volunteers, we will not be performing any tree removal and when building native trails plants will be carefully transplanted.

Where trails incorporate technical features, a bypass will allow bikers and hikers to opt out and detour features that may be beyond their skill level or interest.

Finally, bicycles will not be allowed off-trail or on pedestrian-only trails, and bicycle trails are unidirectional.

The map shown here is our preliminary concept map and is subject to revision based upon public input, environmental and geotechnical review, and the location of natural features.

29- IMG_6221Public Input

The Project Advisory Team (PAT) prepared a schematic design for the outer-loop trail, plus metrics to measure the success of the project, and a mechanism for receiving public input and providing information to the public.  The PAT members overwhelmingly recommended that the Park Department prepare a comprehensive trail plan that includes trails crossing the greenspace.  The PAT process is now completed, but public input is still needed to the Park Board of Commissioners and the City Council — see our news page for more information.  

Please pledge your support by completing this very short Support Form.  We continue to use these pledges to gauge ongoing interest and to provide pledged match volunteer hours for pursuing grant funding.

In addition to coming to a public meeting you are welcome provide us direct feedback using the form below.  We will utilize this feedback to inform our approach throughout this project.
