Bonneville Power Administration (BPA) proposes to remove an existing 7-foot-tall chain-link fence surrounding the Tacoma Substation and replace it with a new 8-foot-tall chain-link fence (2,632 linear feet). Four (4) 4-foot-wide pedestrian gates, three 10-foot-wide gates, one 15-foot-wide double gate, and five 20-foot-wide double swing gates would also be installed.
