I'm a bit suprised that they are proposing both residential towers as rental (which is a good thing).
I'd forgotten that only new condos need to meet IZ rules and that purpose-built rentals have no requirement. I guess the 32 affordable units weren't required at all (and thus a bonus)... but less than 4% of the residential total still seems low (maybe the huge scale of the office/residential development makes that number seem artificially low).
"The application proposes 832 dwelling units all of which are currently proposed as rental units. The applicant has offered to provide 32 affordable rental dwelling units through a Section 37 contribution with the City as a community benefit."
