It’s election season, which means Texas local governments are, once again, asking voters to approve huge quantities of new debt.

In fact, according to the Bond Review Board’s bond election database, Texas cities, counties, school districts, and special districts are seeking voter-approval for 231 separate propositions, which are worth a combined $30.86 billion. If these bonds all pass, that would bring the total debt held by local Texas governments to a staggering $530.59 billion. As in years past, school districts represent the bulk of governmental entities looking to borrow, with 129 of the 231 propositions on behalf of the ISDs. Celina ISD is responsible for the largest proposition, requesting $2.28 billion to fund new school buildings and buses. Collin and Fort Bend counties together are responsible for 46 propositions, totaling $7.6 billion for 26 propositions and $4.2 billion for 20 propositions, respectively.
