Requirements

  • Interested firms must be able to provide all management, tools, supplies, parts, materials, equipment, transportation, and trained labor necessary for the construction of a new flood diversion system and to maintain the existing system. The new structural components to be constructed upstream from the existing dam and tunnel include a diversion structure; an 18-foot diameter tunnel capable of conveying approximately 8,500 cubic feet per second of flow lined with granite pavers. A 150-foot-long new tunnel outfall extends over Lowell Point Road and discharges directly on the east side of the road near Resurrection Bay. The plan includes the selective removal of larger trees in the Lowell Creek Drainage upstream that could potentially become part of the debris flow and cause a blockage of the tunnel. The new diversion system essentially captures all the creek flow originating in the drainage; however, this also refurbishes the existing tunnel so it can provide backup for the new diversion system, or to accept diverted flow during inspection and maintenance of the new tunnel.
