Round Rock's got it all figured out – at least according to S&P Global, which reaffirmed the city's AAA bond rating. Citing "very strong" management, budgetary performance, and a booming economy, the ratings agency is giving its seal of approval for the city's latest financial maneuvers. The AAA rating is the highest on the charts, and it spells out lower interest rates and big savings for Round Rock's upcoming projects.

On the back of this good news, announced in April, Round Rock's City Council is on a green-light spree. They approved a series of debt issuances that include $20 million in GO bonds for parks and recreation, and public safety projects. Another $20 million in COs is earmarked for road work and expanding the Bob Bennett public works complex, and let's not overlook the $8 million in limited-tax notes for new fleet assets. But thanks to their top-notch rating, the city stands to save about $875,000 in interest compared to if they'd been saddled with a mere AA rating, says Garry Kimball, the city's financial advisor, according to Round Rock's website.

So, what's cooking in Round Rock that's got S&P seeing stars? For one, it's their proximity to Austin and a slew of educational hubs that's drawing a bevy of brainy types to the high-tech fields there. This brain gain is driving economic growth that just won't quit. And, there's something to be said for the city's financial gurus, with their lauded "robust management policies and practices" that keep the fiscal ship steady.

"Round Rock has historically used operating surpluses and excess reserves to fund additional discretionary transfers and large one-time capital expenditures that would otherwise be funded with debt," as stated by the Round Rock Texas. These financial power moves give the city extra wiggle room, which they can tighten or cut loose if money gets tight.
