In 2005, Sandy Springs outsourced almost all functions of the city government (with the exception of police and fire) to a single company, which runs the town. That company is in charge of running all the vital functions of government, from the running the parks, to paving the roads, and even 911 calls!
The town is run very efficiently, with zero backlogs in permit requests. Call the city, and you'll be surprised to find that you actually get a friendly person on the other line! The city has a 24/7 non-automated customer service hotline which fields about 6,000 calls per month. It also has a state of the art traffic system with cameras and a high tech command center.
