Columbia invested money in a new Athletics building on the site (weight rooms, offices, etc) They haven't invested anything new into the football stadium, which in current form hold ~15,000. They could do a deal where they rehab the stadium and long term lease/facility share as the football team only plays there 5 times a year plus practice. But for that kind of dual use, they prob play on turf. Not ideal. The soccer stadium holds 5K and not much room to build that out unless they ate up some practice field space. As far as travel, it's 5 minute walk from 1-train, A-train and MetroNorth but abosultely no car parking spaces at all. Might make for an interisting interim solution until a permanent space is found.
totally self-centered in my support of this solution as I'd walk out my front door, cross the street and be on my club's grounds. Just a short stumble home post game as well....
