Issue: Some improvements made by easement holder, including drainage outlets and asphalt, are unsustainable. Recommendation: Work with easement holder to identify appropriate re-engineering / re-construction necessary for sustainability. DC-1, Lilac Trl-2,3,4,5. Issue: Damaged Asphalt. Recommendation: Following consultation with easement holder, repair road surface and replace with suitable road base to maintain vehicle access. DC-3, North Ridge Trl-1. Issue: Trail closed due to landslide / slope failure. Road not necessary because vehicle access can be maintained via the Telegraph Canyon Trl. Recommendation: Install a foot bridge over landslide, and convert the road segment to a trail. DC-4, Telegraph Canyon Trl, Corridor. Issue: Trail parallels Telegraph Creek and is frequently inundated and washed out in places. This trail is a controlled access road that crosses Telegraph Creek in multiple locations. Crossing the creek in a vehicle is often difficult and causes streambank erosion. Recommendation: Minor re-routes and re-engineer where needed and feasible to improve sustainability and maintain vehicle access.
