Firefighters from Leetsdale, Fair Oaks Volunteer Fire Protective Association in Leet and Big Sewickley Creek Volunteer Fire Department in Bell Acres all voted this month to move discussions forward. “We’re still new to this,” said Tom Kuny, president of Big Sewickley Creek Volunteer Fire Department in Bell Acres. He said the Quaker Valley School District is about 21 square miles and includes 11 communities, including Leet, Leetsdale and Bell Acres. Leetdale and Leet firefighters unanimously voted to move discussions forward on Jan. 12. The number of volunteer firefighters in Pennsylvania plummeted almost 90% from 1970 to this year, according to the Pennsylvania Fire and Emergency Services Institute.
