Excuse me, but this upzone was not about housing.  That's how they sold it, but they know that current economics aren't going to make any residential high rise development pencil out in the University District.  They're doing it to support the UW's ambitions for a "high tech incubator" district, and they evidently hope for high rise office buildings.  Full of well paid high employees who will need places to live - that's the housing connection.
