Voters on Tuesday will decide whether 10 school districts in Sonoma County can borrow a total of $584.2 million in school bonds to make what they describe as critical updates to their schools.

Typically, bonds are required for large-scale projects such as new construction or building renovations. If approved by voters, a district would borrow money from a financial institution to be repaid by taxpayers with annual interest over the life of the bonds.

A handful of bond support campaigns are supported by community members and organizations who donate thousands of dollars. No organizations appear to report raising money against any of the bond measures.
