The Alaska Department of Transportation and Public Facilities (DOT&PF) and Federal Highway Administration (FHWA) published a Final Environmental Impact Statement (EIS) and Final Section 4(f) Evaluation on March 9, 2018. The Final EIS and Final Section 4(f) Evaluation comment period runs from open March 9 to April 16, 2018. DOT&PF and FHWA will consider comments received as they prepare a Record of Decision.

The Final EIS is a large document with many components. The Executive Summary is intended as a short and easy-to-read synopsis of the entire EIS, but it necessarily leaves out detail. The full text of the Final EIS provides detail, and still more detail may be found in Related Reports published separately.

All build alternatives would use land from protected properties in the greater Cooper Landing area, so FHWA is required to select the alternative that has the least overall harm. This chapter presents a Least Overall Harm Analysis that drives FHWA decision making.
