Baker Bay – West Sand Island Historic Navigation Structures

Project Overview:

The Baker Bay West Sand Island pile dike system was constructed in the 1940’s. With the system being over 50 years old, it meets the minimum age requirement for the National Register of Historic Places (NRHP). USACE originally constructed the Lower Columbia River (LCR) Federal Navigation Channel (FNC) in the mid-1920s. USACE has maintained the LCR FNC since original construction with dredging, in-water placement, upland dredge material placement sites in the Lower Columbia River and constructing navigation structures (pile dikes and islands).

Scope of Work:

PanGIS PI led a team of qualified staff providing services to support the rehabilitation. They performed a cultural resource inventory of the pile dike system (4 pile dikes) with approval to Oregon Archaeological Records Remote Access OARRA), recorded the pile dikes on Oregon Inventory of Historic Properties Section 106 Documentation Forms, evaluated the pile dike system for the NRHP, and prepared a National Park Service (NPS) 10-900 form for the pile dike system.
