RFP: Heavy Lift Helicopter Services for Stream Restoration

East Fork Grays River and Tributaries –  Heavy Lift Helicopter Services for Stream Restoration.

General Scope of Work: 

The Cowlitz Indian Tribe (Tribe) has secured grant funding through the Washington Recreation and Conservation Office (RCO), from Washington Coastal Restoration and Resiliency Initiative (WCRRI), and the Salmon Recovery Funding Board (SRFB), specific for  a large-scale 3.1 mile instream habitat restoration project on the East Fork Grays River and adjacent tributaries (including Mitchell Creek & Left Bank Tributary) in Pacific County, Washington.  To obtain materials for the proposed projects, the Tribe purchased 40 acres of timber on Rayonier property, located along the Lower East Fork Grays River approximately 10 miles up Fossil Creek Road (7000 Road) from the Highway 4 intersection.

The Tribe contracted with a logging company to harvest the timber. The contractor excavated (tipped), removed, and banged clean each whole tree and decked them within the harvest units for helicopter delivery to the project sites. On average, the whole (full length) trees are 11 – 13” DBH, have rootwads attached, and are approximately 70-80 feet long. Additionally, the Tribe has several additional decks of larger key logs, including approximately 15 – 24-inch DBH trees that are between 40-80 feet long with rootwads. The Tribe also anticipates the heavy lift helicopter contractor will fly pre-made boulder collars (two boulders drilled and connected with wire rope/cable and epoxy) to several designated large wood habitat structure locations.

The legacy of an ancient people in southwest Washington is rich with descendants who manage a growing portfolio of health, education, scientific research, housing, transportation, development, elder care, conservation and legal issues. The Cowlitz Tribe is a growing force in community building in what are now Clark, Cowlitz, Lewis and parts of Pierce, Skamania and Wahkiakum Counties, a vast territory occupied by numerous Cowlitz villages prior to non-Cowlitz exploration and seizure. Today, an elected Tribal Council is composed of professionals adept at managing multiple programs and projects.
