Voters will decide Tuesday on a referendum on the possibility of renovating the Polk County court-house system.
Voters turned down a $132-million plan in 2008 that involved building a courthouse.
The new plan would cost $81-million. The old Wellmark building, main jail and current court-house would be renovated.
The referendum must be approved by 60 percent of the vote. If approved, property taxes would rise about $18 a year for a $150,000-home.
