Ediz Hook Nearshore Restoration
DNR is working in partnership with the Lower Elwha Klallam Tribe to restore more than 1,200 linear feet of shoreline along central Ediz Hook.
This project is the third of three phases of restoration of central Ediz Hook.
- Restored 1,800 linear feet of shoreline to the west of the proposed site and included grading and placement of 22,000 cubic feet of sand, installation of large woody debris (LWD), and re-vegetation with native dune grass and wildflowers.
- The second phase, conducted at the proposed site in 2008 removed an "A-frame", a derelict 770-foot long creosote-treated structure.
The historic natural processes have been cut off to the Hook, a naturally occurring spit. In addition to an existing fill pad, the damming of the Elwha River, feeder bluff armoring west of Ediz Hook, and extensive armoring of the north side of the spit in order to protect Ediz Hook Road, have all contributed to a loss of sediment supply to the site.
This third phase will restore habitat-forming processes along an additional 1,200 linear feet of shoreline where the "A-frame" once stood and is adjacent to a documented sand lance spawning area. The long-term presence of the hardened elements and unnatural steepness of this shoreline have resulted in continuous undercutting of the filled areas and loss of fine sediments and gravels.
Project elements will include: removal of fill material and regrading; concrete debris demo and removal; asphalt demo/removal; riprap salvage/removal; removal of pile stubs and bulkheading. Restoration elements will include placement of LWD for stabilization along with buried riprap to protect the adjacent road from continued erosion; placement of gravel and sand to replace fill material and backfill between road edge and LWD; and plantings of native vegetation.
DNR and the Tribe each contributed funds in 2009 to develop a feasibility study and design for the project. The Tribe then applied for and received a grant from the EPA to support the restoration. It is anticipated that construction will begin in early summer of 2011 and be completed by the fall.
