It would be nice to have a clean version of this whole thing to get started with, optimized. No anything SOUTH, no tearing down of churches, no making the homeless problem in NYP even worse by eliminating places outside Penn that help them. Plus a parallel project to fix things in and around Penn economically, such as rebuilding the pedestrian passage from Penn to PATH / 6th Ave subway. Make Penn work better, and then do a careful non-political planning process. In the meantime start the tunnels, do Portal the best way possible (whatever that is), and get tunnel repairs underway for real.
