Municipal bonds allow cities to fund major projects such as roads, parks, facilities and other capital expenses. Bonds are issued and repaid over an extended period of time, similar to the way many buyers finance the purchase of a home. This strategy helps keep costs more equitable between current and future residents - after all, many of the people who will enjoy these amenities haven’t even moved here yet!
Before issuing bonds which could potentially impact the tax rate, Texas cities are required to put any bond proposition to a vote. If a proposition receives more than 50% of the vote, bonds may be issued for the purpose specified on the ballot.
