What it means: The St. Vrain Valley School District is asking for a $739.8 million bond issue to pay for five new buildings. The plan includes three new schools to handle expected enrollment growth over the next 10 years in the Carbon Valley, Erie and Mead areas, as well as a second Career and Technical Educational Center for those students. There also would be a new building for Longmont's St. Vrain Community Montessori, a charter school. Along with new buildings, the proposal includes money for maintenance, repairs and safety improvements at existing schools, and money to add classrooms and reconfigure outdated spaces. To raise the money, the district would extend mill levy increases authorized by voters for previous bond issues. Property taxes would not increase. With interest, the estimated total repayment cost is $998.9 million.

What supporters say: The bond issue is needed to address enrollment growth and expand access to career and technical education offerings. Delaying maintaining schools as buildings age and major systems reach their end of life also will allow buildings to deteriorate and costs to increase. Bond spending will be overseen by a public accountability committee, ensuring the money is spent as intended.

What opponents say: Taxes are too high, and property owners, especially those on fixed incomes, would benefit from a tax reduction if the measure isn't approved. The district should use its operating money for building maintenance instead of going into debt and should require developers to cover the cost of new schools needed because of growth.
