The Des Moines School District is taking a $70-million loan in order to make improvements to facilities.
The school board recently approved the first step in selling $70-million in sales tax revenue bonds.
The bonds will be paid off using the one-cent local option sales tax.
In 2013 Des Moines will collect $27-million from the tax.
Planned improvements include new buildings, new windows, electrical upgrades, and security measures.
Construction will begin next year.
