<p>I thought the potential sites for new colleges were at the corner of Prospect Street, adjacent to the engineering buildings. I think the College Street site would be reserved for major academic or cultural buildings. But, as you point out, the College Street site would obviously be better if Yale wants to retain the title of having the most compactly-located undergraduate dormitories in the Ivy League (a fact which directly translates into it having the best undergraduate social scene, by far, because everyone can visit or party with each other in a matter of two or three minutes). If Yale built them up on Prospect, it still wouldn’t be as bad as Harvard, but it would still be a negative.</p>
<p>I don’t think it will happen in the immediate future, because Yale is simply expanding too rapidly (spending close to a half billion dollars in new construction every year) to add additional $100+ million projects. From what I hear, the campus this summer looked like one massive construction site, with almost every street blocked off for new buildings.</p>
