Town officials this month upheld a $150 ticket issued to a Norwalk woman who’d parked in a disabled space on Main Street on a Tuesday morning in May. Kim Scavo told members of the Parking Commission during her July 8 appeal hearing that she was confused because the disabled space outside the New Canaan Fire Department is designated by a sign affixed to a nearby railing, not a curbside post. The blue paint on the street that normally indicates a disabled space also isn’t visible as it is for other such parking spots in town, she told the Commission during the hearing, held via videoconference. “I don’t feel it’s clearly marked and I did not do it intentionally at all and I just don’t understand and I don’t think it’s fair,” Scavo said. The commissioners said the space was clearly marked by the sign and that any motorist pulling into the spot should have noticed it.
