Abstract:

A salt marsh development project originally planned for Rennie Island in Grays Harbor, Washington, was terminated after a detailed baseline analysis. These studies indicated that extremely high wave energy conditions at the site would make marsh development infeasible without a substantial protective and retaining structure. Foundation analyses indicated a weak, unstable condition that made a conventional rock or earthen dike unsuitable. An evaluation of various alternative structures revealed that no economically feasible options were available, so the marsh development project was terminated. Author
