The estimated levy rate increase is derived from the total cost of work included in the final bond package. That is, in order to raise $619.7 million through a 20-year general obligation bond, the current levy rate would need to increase by an estimated $1.24 per $1,000 of assessed value. Community polling indicated support for a property tax increase between $1.51 and $2.50 per $1,000 of assessed value. For this reason, we understand your question to be, “How did the School Board arrive at the final bond package total?” The Bond History page provides a summary of how the bond package was developed. In short, the School Board directed district staff to create a package that addresses as many facility needs as possible, to incorporate the feedback heard in a community phone survey and keep the package total under $620 million.
