Pete Stidman of the Boston Cyclists' Union explains the city should have talked to local residents first, because the lanes just showed up while they were looking at angled parking on Main Street as a way to increase parking for stores there:
Normally, when two competing interests arise like this, the neighborhood has a chance to talk them through and see options on designs that attempt to address both concerns. This happened recently in the St. Mark's neighborhood of Dorchester when the plan for a bike lane on Talbot Avenue also came up against some interest in angled parking. In that case, the Union brought the neighborhood and city planners together and it was found that angled parking would not create a significant number of new parking spaces due to the configuration of the street, and the neighborhood agreed that a bike lane might also be a way to get more customers into their shops. Talbot is now painted and appreciated and the St. Mark's neighborhood is on its way to becoming a very bike-friendly place.
But in this case in Charlestown, that competing interest was not identified or discussed with the Charlestown Neighborhood Council beforehand.
