The new guidelines will likely address issues such as access at street crossings for pedestrians who are blind or have low vision, wheelchair access to on-street parking, and constraints posed by space limitations, roadway design practices, slope, and terrain. The town is trying to figure out where to install curb ramps to provide access to the town hall.
