Updates to the plan are critical due to dramatic changes to Sandy Springs’ economic, residential, and industrial profile since the 1990s, said Christina Pastore, a traffic engineer and planner for Kimley-Horn and Associates, who is consulting on the project.

North Fulton’s population density has more than doubled since then — from 168,000 to 380,000 residents — with substantial growth up to the Ga. 400 corridor. Baby boomers and millennials are half of the population in the North Fulton area, and their incomes and lifestyles dictate transportation choices, Pastore said.

“Maybe they want to be able to live in a place where they can walk out of their house, and to a restaurant, or a grocery store, and to not have to drive everywhere,” she said.

Kathryn Hardy has lived in Sandy Springs since the 1970s, and has seen the city go from “small and laid-back” to an area that is swelling with high-priced apartments. That means more cars and more people — two things Hardy fears Sandy Springs can’t sustain.

“I think it's pretty grim,” Hardy said. "We're worried about the values of our homes going down ... it's too much for this little area."
