By Sara QuamLocal taxpayers will help Rock County Senior Citizens with some building expenses.Representatives of Rock County Senior Citizens Eileen Kopp and Alyce McClure asked Rock County Commissioners last week to find a way to give to the group.Kopp said, "The building is used by Rock County a lot. … We were wondering if you can do anything to help us."Commissioners voted to give a one-time donation of $1,500 and to revisit the amount it pays in rent during the budget process. The county pays $500 a month rent for Extension Service, 4-H, Retired Senior Volunteer Program and storage. The group has had an expensive couple of years: a new roof cost $18,000, termite treatment cost $3,800, and a refinished floor cost $1,493.The group is anticipating a major purchase of a furnace and air-conditioning system within the next few years. It has $73,000 in investments and savings.Senior Dining is a separate entity from Senior Citizens. The meal service earns Senior Citizens 8 cents per meal served, which amounted to $3,500 last year.
