At a recent MBTA board meeting, it became alarmingly clear that the MBTA is behind in its planning for climate resiliency. Add that challenge to the challenges of catching up on maintenance, assuring safety, and expanding service. Andrew Brennan, Senior Director for Energy and Environment, explained to the board that the MBTA completed a “high-level” vulnerability assessment of the system in 2017. His presentation materials are here and his talk begins at 2:55 in this livestream of the June 10 board meeting. The 2017 high level assessment revealed the obvious: Namely, that the most exposed asset is the Blue Line and that the greatest risk to the Blue line comes from flooding due to sea level rise. Only months after the assessment, the winter high tide of 2018 flooded Aquarium station. As to the lowest lying assets on the Blue line (Aquarium station and the Orient Heights Maintenance Facility), more detailed engineering studies have been completed to identify just how they would be flooded and what can be done to protect them: for example, raising openings like vent shafts and raising the most water sensitive components like transformers.
