Document Description
The proposed project involves pulling the MX Track area back from the river to an existing parking/picnic area, reducing the chances offload damage in the future. The existing parking area, picnic tables, and trials area would be moved to the east side of the river bar. Fill from the old track would be used to build bank turns and jumps on the level portions of the relocated track. After boulders are removed from the slope of the Trials Area, fill would be used to incorporate additional turns, minimizing the need for fill placement. Because this area is adjacent to the ascending canyon flank, the track would be engineered to effectively control surface runoff from the upslope terrain. The track would be fenced to prevent access during non-operating days.
