The marina bulkhead's proposed replacement consisted of a sheetpile bulkhead tied back to a concrete deadman anchor.

To evaluate subsurface conditions, Shannon & Wilson supplement existing explorations by drilling four borings. The borings indicated the presence of approximately 35 feet of liquefiable soils over beach and glacial deposits. Shannon & Wilson calculated static earth pressures and performed seismic analyses to evaluate dynamic pressures on the new bulkhead for several design ground motions.  Working closely with the structural engineer, Shannon & Wilson provided recommendations for an anchored bulkhead design that would meet the economic and performance criteria established by the Port. During construction, Shannon & Wilson provided consultation as needed by the Port for Segments A and B of the bulkhead replacement.

Under a separate contract, Shannon & Wilson provided conceptual design recommendations for the adjacent Landing North Wharf to the south and west. This evaluation included providing recommendations for a new sheet pile bulkhead as well as a riprap buttress slope.
