Specifications include, but are not limited to: A. All trails are located conceptually per the plan. 1. The qualified Bike Park/Trail Building contractor shall ground truth and flag the plan to achieve the design intent described in the following trail descriptions and from attached concept feasibility plans. Each trail shall consist of rollers, berms, jumps, drops, and some wood or stone features to achieve the conceptual plans and description of each trail and trail user experience. B. A designed grade reversal or constructed rolling grade dip should occur approximately every one hundred feet (100’). 1. Any grade reversal must be strongly anchored with a significant landscape feature, boulder, or large tree or trees, to discourage short-cutting or social trails. 2. In mountain bike-specific trails, grade reversals also double as flow elements, such as rollers, jumps, and pump/rhythm sections. 3. In this context grade reversal shape, size, and placement should reflect the specifications for its location within the system. C. The vendor shall be responsible for the existing trails within proximity of the conceptually located new trails. 1. Whereas if existing trails are to be part of the new trails, the vendor must ensure that the trail meets project specifications. 2. If existing trails are not included in the new trail system, the vendor is responsible for removing clear access to close and not conflict with trail users. D. While the exhibits following these specifications conceptually depicts the location, configuration and length of the trail, the vendor shall include a GPX of final flagging to demarcate the proposed locations of each trail which must receive written approval from the City prior to construction. E. The vendor shall ensure that reasonable precautions are always taken to protect the public where work is being performed. 1. Not limited to signs, yellow or brightly colored construction caution tape and more will be utilized to keep the general public out of active trail construction sites. F. These trails are to be built with minimal impact on the overstory trees and the surrounding forest. 1. Only brush and small trees shall be removed from the trail corridor. 2. Trees larger than 4” require permission from the City before they are removed. 3. Removal of healthy trees approaching this size shall be avoided and only done when there is no better option. 4. Dead, dying, and rotted trees can be removed to open the trail corridor as necessary for grading or if they present a clear hazard to trail builders or trail users. G. Wood material such as stumps, logs, roots, and brush shall be removed from the trail tread. H. Debris shall be cut and scattered or hauled off. 1. All branches, roots, and brush to have a maximum pile or stack height of eighteen inches (18”) above grade. 2. No debris shall be left within ten feet (10’) of the trail measured from the center line of the trail. 3. Cut brush and slash must be disposed of in a location out of streams, gullies, swales, low areas, and suspected wetlands.
