Approving the increase were board member Roy Angst, Anthony DeMarco, Michelle Markovich, Irene Genther, and Board President Jeff Markovich.
Opposed were Dan Heaney, Bill Hunsicker, Brian Dolena and John Williams.
Initially a 3-mill increase was proposed but that was defeated by a 6-3 vote. In favor were Hunsicker, Heaney, and Dolena.
