The combined Final Environmental Impact Statement (FEIS) and Record of Decision (ROD) was signed in January 2021. The FEIS, which began in March 2018, following the completion of the Draft Environmental Impact Statement (DEIS) process, further identifies environmental and community impacts and commits to specific mitigation and minimization actions to eliminate or reduce negative effects. The ROD is the official decision document of the Federal Transit Administration (FTA) for KOP Rail to continue into further engineering and construction of the project. After the FEIS/ROD phase, preliminary engineering will continue to approximately 30% of the design. You can read the KOP Rail FEIS/ROD.
Environmental Impact Statements are required by the National Environmental Policy Act of 1969 (NEPA) when a federally funded project is determined to significantly affect the quality of the human environment.
