Trail Construction Scenario.pdf

Description of Work

Trail history and condition:

Trail 102 new construction is a full bench contouring trail open to mountain bikes. The new construction segment is tight flagged every 10’ along the entire alignment. Most of the trail is side hill construction through moderate to heavy brush. This area was burned in 2017 and there are many downed trees that will need to be bucked or moved during construction. The contouring alignment shall be constructed with grade reversals every 200-300’ and must achieve a reverse grade which will be verified by clinometer. Special qualifications for construction of mountain bike trails apply.

Trail Design Parameters (from TMO):
