Plywood Mill, WA
The industrial plywood mill in Anacortes, WA has been repurposed into a public use wetlands recreation area created by the Custom Plywood Sites Phase II Interim Redial Action Project. eTrac performed the high resolution hydrographic and terrestrial surveys for Pre-Construction information and Post-Construction as-built conditions. The Pre-Construction data proved valuable for the removal of hundreds of piling and other abandoned structures as well as the bathymetrical conditions for the Pre-Dredge surface. The hydrographic surveys were conducted using Real-Time Kinematic (RTK) GNSS Positioning for high-level accuracy horizontal and vertical positioning. The pre-construction survey showed in high resolution the existing bottom conditions in addition to all the submerged structures that could not be accounted for using traditional topographic techniques.
