Updated 8:15 a.m., Oct. 25 A $691 million bond on the November ballot is expected to pay for a number of projects within Frisco ISD, including building new schools, maintenance projects and facility expansions. The bond is lumped into one proposition. According to state law, school districts are not required to break up bonds into multiple propositions. In a previous article, FISD board of trustees President John Classe explained the bond is under one proposition so the school district has the flexibility to adjust the cost of projects as needed. Changes in student enrollment growth, construction costs and other factors can also affect projects in a bond program, according to the district. The projects with the largest allocation of bond dollars include new facility construction, preventive maintenance and facility upgrades.
