Red Line Extension

Supplemental Environmental Assessment (EA) and Section 4(f) Evaluation

Overview

The Federal Transit Administration (FTA) and the Chicago Transit Authority (CTA), in cooperation with the Federal Highway Administration (FHWA), finalized the Red Line Extension (RLE) Supplemental Environmental Assessment (EA) and Section 4(f) for the RLE Project on January 4, 2022. The agency coordination and outreach associated with the Supplemental EA have influenced the design refinements incorporated into the Preferred Alignment and analyzed in the Final Environmental Impact Statement (EIS).

The National Environmental Policy Act (NEPA) requires evaluation of potential environmental impacts associated with federal projects and actions. 

In 2020, a Supplemental EA was determined to be required for the RLE Project to evaluate the three project changes that have occurred since the publication of the Draft (EIS) in 2016. The project changes are:

  • 130th Street station relocation
  • 120th Street yard and shop refinement
  • 107th Place cross-over

On January 31, 2022, the FTA and CTA announced the availability of the Supplemental EA and Section 4(f) Evaluation for the RLE Project. This document evaluates the three project changes that have occurred since the publication of the Draft EIS in 2016. The purpose of the Section 4(f) Evaluation is to discuss mitigation and enhancement measures proposed for Beaubien Woods Forest Preserve. These mitigation and enhancement measures were developed in consultation with the Forest Preserves of Cook County.
