I think I have the solution: Transfer the Level 4 Biolab there from the South End. There's already a perfectly good hole for building subterranean labs for studying Ebola and Black Death and other deadly microbes. There are hardly any residential neighbors to form committees to complain about safety concerns. It will be so convenient for scientists and technicians to leap off the Orange and Red Lines right into their basement (formerly The Basement, sob) labs. And when it's time to evacuate, what could be easier?
