Emergency stabilization efforts occurred in 2016. The current channel stabilization design represents input from National Marine Fisheries Service, Regional Water Quality Control Board, as well as NPS technical staff (geomorphologist, aquatic ecologist) and engineering hydrologic consultants. The specifications and drawings call for stabilizing the footprint of the culvert failure and head cut with an engineered rock ramp, construction of three rock step pools to provide for some habitat for aquatic animals, and the removal of a buried and rusted corrugated metal culvert (80 ft). Work would occur along up to 250 ft of creek. In addition, an adjacent gully (75 ft) that is actively contributing sediments to downstream Redwood Creek would be stabilized and filled to reduce future contributions of fine sediments. Existing bank and bed materials would be re-used either in the channel or as fill for the adjacent gully. Rock slope protection would need to be purchased and transported to the site.The Contractor shall provide all supervision, labor, equipment, testing, and supplies necessary to complete the work as identified in the project specifications and associated documents provided as attachments to the solicitation.
