2. On the map, the section at the end of the green trail, near the green square: This section was suffering <br />significant erosion. This was due to a relatively steep grade through looser soil, and a narrower corridor <br />area to work within for the design and build. <br /> The proposed solution identified a lower alignment reroute to soften the grade, resulting in a trail <br />more resistant to rider wear & tear and water erosion. <br /> Some volunteers discussed armoring the existing section to address erosion issues and <br />enhance the trail experience. It was acknowledged that armoring would increase the difficulty of <br />the section. <br /> The volunteers decided to explore the feasibility of a hybrid option to accommodate as many <br />riders as possible, while enhancing the riding experience at the trail as much as possible. <br /> Volunteers began work to repair the existing upper trail and construct a new lower trail in <br />August. <br /> The upper section was partially armored to prevent the identified erosion issues, and this trail <br />has been identified as the more advanced trail. <br /> The lower section includes a softer grading which is at or below 8% and will act as the bypass <br />trail for beginner riders. <br /> <br />3. On the map, the section at “F”: During the trail build, the contractor (Trail Source LLC) advised the Trail <br />Steward that the soil in this area of the park does not compact well. Dirt grade reversals were built, <br />some of them were armored. It was not feasible or within budget for the contractor to armor all of the <br />dirt grade reversal features, and the contractor advised the volunteers to observe the area and armor <br />when/where needed. <br /> The proposed solution was to provide additional armoring to better preserve the dirt in the area. <br /> Funding was secured in July to purchase rock to armor the identified issue areas and the <br />armoring reinforcement took place in late July. <br /> Beginner riders can roll over the rocks and more advanced riders can use them as jumps. <br /> The rock supports and preserves the existing engineered dirt rollers. <br /> During the work, the existing rock shelf in the area showed signs of riders attempting to bypass <br />the line, a bypass line was built to accommodate those riders and armored with flat rock to <br />prevent erosion. <br /> <br /> <br /> <br /> <br /> <br />
