Archaeological fieldwork consisted of pedestrian survey, shovel probe excavation, magnetometer survey, completion of geotechnical cores, and mechanical test pit excavation. Six archaeological sites and one isolate were recorded during fieldwork. These include 45KP252 (Pre‐contact Shell Midden), 45KP253 ( Historic Dump), 45KP254 (Babcock Dairy and Port Gamble Dance House), 45KP255 (Port Gamble Chinese Laundry and Residences), 45KP256 (Port Gamble Workers Housing Debris Scatter), 45KP257 (an isolated historic bottle base), and 45KP258 ( Culturally‐Modified Cedars). In addition, probable historical debris was identified in many of the excavations. Sites 45KP252 (Pre‐contact Shell Midden), 45KP254 (Babcock Dairy and Port Gamble Dance House), 45KP255 (Port Gamble Chinese Laundry and Residences), 45KP256 (Port Gamble Workers Housing Debris Scatter), and 45KP258 ( Culturally‐Modified Cedars) are recommended eligible for listing in the National Register of Historic Places (NRHP). Sites 45KP253 ( Historic Dump) and 45KP257 (an isolated historic bottle base) are recommended not eligible by the Washington State Department of Archaeology and Historic Preservation. Adoption of the Port Gamble Historic District boundary as delineation of an archaeologically sensitive area is also recommended along with development of a plan for inadvertent discovery of archaeological or human remains. Development of a management plan for future treatment of both potential and known archaeological resources during for the project is recommended, as well.
