​I-5 Corridor Reinforcement - Draft EIS

Links to the draft EIS are below. Useful information to have before reading the EIS is included in Notes to Reader. Below, you may click on specific files you wish to view. BPA accepted comments on the draft EIS from Nov. 13, 2012 to noon March 25, 2013.

Maps are not embedded in the chapters and are listed in their own files. Maps are named by the chapter in which they appear. For example, Map 2-1 appears in Chapter 2. Some maps appear in a series, for example, Maps 5-1A through 5-1D. These maps split the project area into four sections to show greater detail.

Files vary in size. Large files are split into several smaller ones, but some files are over 30 megabytes and may take a few minutes to load onto your screen.
