Overall, the general consensus was that improvements to State Route 117- a sidewalk or multiuse path, and widening the shoulder for bikes- was essential. Also agreed on was the potential for a multiuse path alongside the train tracks, running from Pleasantville to Chappaqua to Mount Kisco. A sharrowed system of bike paths could also run on local roads with minimal 117 use.
One neighbor mentioned the need for a safe bike path to the North County Trailway entrance in Pleasantville; another mentioned the lack of bus shelters or safe access to bus stops.
I'm in the process of contacting town planners for Chappaqua to find out the status of the sidewalk project, which has already been partially planned and is waiting to be implemented. We discussed the potential for starting a multi-town petition, in the case that the State DOT is in charge of the project, or that the planning board dismisses our ideas.
