The two-story, 70+ year old restaurant was located in an active slide area along ChuckanutDrive.   The structure had experienced significant movement and cracking over its life as the earth movement caused the northern portion of the building to move laterally and settle.   The team of Shannon & Wilson, geotechnical engineers, MLA Engineering, structural design, and Fisher & Sons, general contractor, provided a system of micropiles, post-tensioned tiebacks, a reaction beam, and concrete outriggers to stabilize the lateral and vertical movement of the foundations.  The damaged CMU walls and wood framing were re-built to provide code-compliant resistance to wind and seismic loading.  Construction, which occurred unimpeded during the winter, included measures to protect the sensitive oyster-spawning stream that flowed within 50 feet downhill of the work.
