It goes into effect July first for ten years.The Western Dubuque School District hopes to get some of those Vision Iowa funds to make a school bond issue more appealing to voters.The district is applying for a million dollars from Vision Iowa. In December, a six-point-four million-dollar bond issue was rejected. It would’ve provided a new elementary school and more classroom space. The Vision Iowa funds could only be used if the bond issue passes later this year.
