Responding to a business owner’s request, town officials are re-designating an area of Locust Avenue as 30-minute parking. The areas directly in front of the Post Office and Joe’s Pizza across the street long have been two-hour parking, as is the rest of downtown New Canaan. Yet town officials recently confirmed with parking enforcement officers “that the people that were parking on that street were not frequenting businesses like Joe’s Pizza or the Post Office—they were using that area to park and go to an office or other places of work,” Parking Manager Stacy Miltenberg told members of the Police Commission during their regular meeting last week. The town long has urged employees of downtown New Canaan businesses to park in municipal lots and leave coveted on-street parking for those seeking to shop and dine here. Last year, the Parking Bureau issued a new type of permit, in Morse Court and the Park Street Lot, specifically to that end.
