Because state law allows the district to borrow a total of $333,479,613, Glenbard Twp HSD 87 has reached 23.2 percent of its debt capacity.
The state limits how much school districts can borrow, capping their debt at a percentage of the district's property wealth, as determined by county and township assessors.
Community unit school districts are able to borrow up to 13.8 percent of their total property value, or Equalized Assessed Value (EAV). Elementary school districts are able to borrow up to 6.9 percent of their EAV.
However, school districts exceeding these debt caps are not punished or sanctioned, as the state has no enforcement mechanism in place.
