Saying there’s an increased need for quick visits to downtown New Canaan restaurants and shops, and that delivery trucks often double-park anyway, town officials this month approve a proposal to convert three loading zones to 15-minute spaces. The Police Commission at its March 16 meeting voted 3-0 to convert loading zones on Forest Street (just past the diner), on Main Street at East Avenue and on Elm Street near the intersection with Park Street into 15-minute spaces. Laura Budd presented the concept to the Commission in her dual roles as executive director of the New Canaan Chamber of Commerce and chair of the Parking Commission, which adjudicates parking ticket appeals. “Obviously our number-one goal is always public safety,” Budd said during the meeting, held via videoconference. She said there are some loading zones in downtown New Canaan that get frequent use and “should not be touched,” such as one on South Avenue at Elm Street, and another on Burtis Avenue.
