What is the logic of determining the allocation of IZ set-aside units (50% and 80% AMI) by zone instead of by construction type (steel/concrete and stick-built)?
The Zoning Regulations essentially permit steel and concrete construction in any applicable zone, and any construction in the denser zone districts to have a reduced affordability requirement. For instance, stick construction in a C-2-C zone would have the reduced affordability requirement. The minimum set-aside requirement of 8% of the gross floor area being devoted to residential use does not appear to recognize common area space. Also, what if there is common area space that is shared with a commercial use? The gross will be converted to a net leaseable/saleable requirement as part of the CIZC application. A gross calculation was necessary to compare the minimum requirement to the potential maximum requirement which is based on gross bonus density. The addition of share common space to the gross residential space will be weighted proportionally based on the square footage of commercial and residential space with access to the common area.
