I did some primary empirical research today to build more solid facts into this Greenway discussion. What I chose to focus on was not the Greenway parks themselves, but the
uses that currently front these Greenway parks on Atlantic, Surface, Cross, etc.
Methodology:
My focus is on the Greenway "median" from Summer Street on the south side to New Chardon/Stillman Streets on the North side. Note therefore that Chinatown parks, for example, are excluded. I walked this corridor multiple times over the past few weeks cataloging the uses, and used Google Earth to estimate distances along the curb of the different uses I noted.
I split uses into four categories:
- Active: active uses including storefronts or cafe seating. Obvious examples include the Panera at High Street and the North End shops along Cross Street by Hanover and Salem. I counted this generously, including for example things like the tourist trolley vendors in the Marriott Long Wharf that face Atlantic.
- Curb-cut/Parking: Where the pedestrian experience is interrupted by curb cuts (e.g. in front of hotels), garage entrances, parking lots adjacent to the sidewalk, harbor tunnel chasms or first-floor garages up against the sidewalk.
- Public park/Open space - Examples include Columbus Park, as well as currently-undeveloped empty block along Blackstone Street.
- Blank wall: Built up streetscapes that are neither active nor parking. Examples include the International Place perimeter, the wall keeping the proles out of Harbor Towers, and so forth.
Results:
I tallied the harbor side and the FD side separately and counted the total sidewalk length on each side (meaning that cross streets are excluded from the total length).
FD side (total sidewalk length 4000 feet):
- Active use: 11.4%
- Curb-cut/parking: 22.7%
- Public park/open space: 9.4%
- Blank wall: 56.5%
Harbor side (total sidewalk length 4700 feet):
- Active use: 17.4%
- Curb-cut/parking: 25.1%
- Public park/open space: 11.7%
- Blank wall: 45.8%
Greenway total along the "median" corridor:
- Active use: 14.6%
- Curb-cut/parking: 24.0%
- Public park/open space: 10.6%
- Blank wall: 50.7%
Analysis:
The results speak for themselves. More than half the sidewalk surrounding the Greenway abuts blank walls. In addition, more than a quarter of it is curb cuts, parking lots, and other uses that degrade the pedestrian experience. Thus,
75% of the surrounding sidewalk abuts no active use. Some of the remainder is open space.
Tallied generously, only 15% of the building facades by length fronting the Greenway present an active use.
My measurements are not definitive, and some of my judgments were to an extent subjective. I wouldn't mind if anyone wants to independently verify this. I don't think the result would come out radically different.
