What is a large building in Flagstaff?

Flagstaff's transect zoning provides a list of building types that may be used. There are several residential building types, one live-work building type and the commercial block type.

Commercial block buildings in the lower intensity urban transect zones, T4N2-Open (Neighborhood) and T5( Main Street), are described as smaller than those in the higher intensity downtown transect zone, T6. This graphic compares the sizes of existing commercial block buildings in the T5 and T6 zones with the Hub, which is also proposed as a commercial block building.

Is the Hub a commercial block building that belongs anywhere in the transect zone area?
