Having set up a process for neighborhoods to request 20 mph zones, the city Department of Transportation has sparked a citywide discussion about appropriate traffic speeds on residential streets. That discussion will come to Park Slope this weekend in a public forum held by the Park Slope Civic Council weighing the merits of a slow speed zone and how it might be implemented in that neighborhood.
