(Audubon, Iowa) – Patrons of the Audubon Community School District are heading to the polls Tuesday, Sept. 14th, to cast their ballot on a Special Election for a Bond Referendum with regard to the district’s facilities.  Voters are being asked to approve a Revenue Purpose Statement (RPS), that would allow them to bond for up to $7.6 million in additional funds — with just under $2 million of that going to refinance a 2013 bond now at lower rates — against the district’s one cent sales tax revenue. Superintendent Eric Trager said the change in the district’s RPS was needed to make sure that there would be enough funding to complete the $10.8 million middle school/high school renovation project.
