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

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

A handful of bond support campaigns are supported by community members and organizations who have donated thousands of dollars. No organization appears to have reported fundraising in opposition to the bond measures.

Here’s what their latest campaign finance filings show.
