Session Title

Bulkhead Removal - Putting goals into practice

Description

This oral presentation will present three recently constructed shore armor removal projects. These projects were selected to represent different conditions in the Washington State shores of the Salish Sea and the varying type of landowners participating in shore armor removal. Pre-project, construction, and post project pictures will be shown as well as specific design and construction constraints.

The first project was completed in summer 2015 on a private residence in Kingston, WA on Puget Sound. The project was initiated through outreach by Kitsap County Department of Community Development. This project removed 110 linear feet of rockery bulkhead on a feeder bluff and a large protruding boat ramp. The project site had an adjacent bulkhead on one side and a very concerned owner on the other side. Fall 2015 storms eroded the bluff toe to produce renewed sediment input and wood recruitment.

The second project was completed in 2014 at a new city park along the Strait of Juan de Fuca in downtown Port Angeles. The property was unused prior to the creation of the park, which anchors one end of a revitalized central waterfront with trails, public places, and other amenities. The project removed substantial amounts of historical fill and a large portion of a 20-foot-high armor stone revetment to construct two pocket beaches. Rock was reused to build drift sills to contain the imported beach nourishing gravel. Two gravel beaches with sandy backshore and native plantings were created.

The final project finished construction in fall 2015 on a Squaxin Island Tribal parcel in Mason County for SPSSEG. A private boat basin was filled, the associated 15-foot-high concrete jetty walls that blocked littoral transport and a private boat ramp were removed. A short time lapse of project installation will be shown.
