Good Catch, John !
That Reach Distance is critical in Winter Months for Pedestrians in
Wheelchairs, for Pedestrians using a Walker to go to Hannaford's or Market
Basket, or going to a METRO Bus Stop, - All of those objectives will require
activating 1 or more Pedestrian Signal Crosswalks, which may have frozen Snow
and Ice, blocking normal Reach Distance to the controls, to Stop Traffic.

Subject: [wsmac] Pedestrian signal guidelines
Hello again, WSMAC,
Local architect and Discover Downtown Westbrook Design Committee member Jill
Johanning recently followed up with her DOT ADA contact on a question we had
about pedestrian request buttons. It was mentioned in the DOT plans for the
William Clark Drive project this summer that the push button "maximum allowable
reach distance" shall be 24" (Sheet 10, "Pedestrian Signals and Push Buttons",
Our first question was, what does "maximum allowable reach distance" mean?
It is the length you have to reach to get the button. In this diagram from ADA
guidelines, it is the measurement at the bottom, recommended to be 255 mm max,
Since the DOT plan says 24" instead of 10", the DOT ADA contact that Jill spoke
to promised she would have it changed to 10" in the project plan. I'll note
this in our WCD Project Notes Document.
Jill included a link to this "Public Rights Of Way Guidelines" (PROWAG)
document from the federal government, which includes lots of information about
recommended dimensions of pedestrian infrastructure in Sections 3 and 4,
