SYDNEY, N.S. — A decision from Cape Breton Regional Municipality on a rezoning application from Kent Building Supplies is expected in August. Kent is seeking a land use by-law amendment that would allow it to purchase a 100-acre tract between the Mayflower Mall and a housing subdivision. The company, a private holding of the Irving family, hopes to build a new store on the lot, with the possibility of further commercial and residential building down the road. Municipal planner Karen Neville told the Cape Breton Post that further development would have to wait for the longer term. The question is complicated by a provision in the Municipal Planning Strategy insisting that new developments be accessible by traffic light. Kent is pushing a roundabout as an alternative option.
