There is a driveway leading from a parking lot next to the Baldwin school, which crosses Oxford St sidewalk (see schematic attached). Every morning that sidewalk is a high traffic area with pedestrians and kids on scooters and bicycles passing by and crossing the driveway. Yesterday a car driving out on that driveway almost hit a kid from my son's class while he was riding his bike, steps away from his father. Can you please add a "stop" sign and ideally a speed bump to remind cars to stop? Currently there are no signs of any kind. We were inches away from a tragedy yesterday. Please help prevent those for the future!
