The current plan calls for a single, primary conveyance from the National Forest boundary on the westside of the Switchback neighborhood, crossing Hwy. 89 and extending to an area east of the East Valley Baptist Church. The construction of this large storm drainpipe system in a very limited space within a residential area will require substantial and special shoring so proposals should include experience with not only constructing a very large storm system but also experience with substantial and special shoring.
