Parent Anna Caruso, whose children have attended Franklin Hill Elementary school for the past seven years, said building a new school on the property would mean some 1,400 children, hundreds of parents, and dozens of school buses would pass through the suburban area every day.
"It's unfair and it's a lack of planning," she said.
