Broadway survey: analysis

A roundup of the Broadway surveys from the 1/2-mile stretch between Foster and Bryn Mawr:
Broadway: 5200 block
Broadway: 5300 block
Broadway: 5400 block, west side
Broadway: 5400 block, east side
Broadway survey: 5500 block, west side
Broadway survey: 5500 block, east side

The only existing structure that is over the 4-story limit for B1-2 is St. Ita's. Of the 57 buildings in the survey area, two are four stories tall, one on the 5400 block, and one on the 5500 block. Here is a complete distribution of building heights (in stories):

Block	1 story	2 stories	3 stories	4 stories	>4 stories
5200	5	1	2	0	0
5300	4	3	1	0	0
5400	5	10	4	1	0
5500	6	7	6	1	1

The question that has been asked is whether Broadway should be zoned B1-2 or B1-3. The former would only allow for 4 story buildings, while the latter would allow buildings as tall as 6 stories. Clearly, the existing scale falls predominantly within the requirements of B1-2; St. Ita's bell tower is the sole exception. If a B1-1 zoning were being considered, I'd note that 94% of the existing structures are short enough to meet the B1-1 height requirement; however, some of these buildings, such as the Jewel supermarket, would likely fall outside B1-1 based on other factors.

In addition to height, there are also some questions of usage. For instance, how many residents know that there is a plastic parts manufacturer on the 5400 block of North Broadway? I would categorize this as an industrial use that does not fit in a retail zone.
