Finding of No Significant Impact

  • Finding of No Significant Impact [4.2MB]
    MassDOT and the MBTA have received full federal environmental approval for the Green Line Extension project. The Federal Transit Administration released a Finding of No Significant Impact (FONSI) for the project, reaffirming the myriad environmental, mobility, economic development, and community-building benefits of the project. Federal environmental clearance is the culmination of several years of technical work done by MassDOT and the MBTA with close cooperation from the Cities of Cambridge, Somerville, and Medford, as well as the participation of hundreds of individuals and local organizations. The FONSI document contains a description of the federal environmental process, mitigation measures proposed for the Green Line Extension project, and an explanation of the public outreach efforts associated with the environmental process.
