Strategic Restoration Conceptual Engineering — Final Design Report This report presents engineering design concepts for a suite of 36 potential nearshore restoration actions identified collaboratively by PSNERP and the larger Puget Sound restoration community of lead entities, tribes, conservation groups, local governments and others. PSNERP will use this conceptual design information to assess the costs and benefits of each restoration action. Feasible, cost-effective, community supported actions with high ecological benefits will be advanced for implementation, contributing to objectives established by the Puget Sound Partnership to recover the health of Puget Sound. While broadly advancing nearshore restoration, these conceptual designs will also allow the U.S. Army Corps of Engineers (Corps) to identify sites which best fit the requirements of their restoration programs and authorities. The ecological benefits of restoration will be calculated in terms of change in ecosystem outputs. The Corps will use this information to select a portfolio of restoration actions that meet federal cost-effectiveness criteria. The selected actions will be evaluated further to verify their suitability to be authorized for implementation by the Corps. All of the restoration actions described in this conceptual engineering design report have the potential to provide important ecological benefits regardless of whether they are deemed appropriate for federal authorization. Some of the actions may be more suitable for implementation at the local level through non-federal programs or partnerships. Report authors and PSNERP team members anticipate that the design information provided by the report will support not only potential implementation of projects through Corps authorities, but also implementation through other federal and non-federal programs, authorities, and funding sources.
