Hall County’s population might double by 2040, not triple, as is forecast in Hall’s current long-term transportation plan. Pond & Co., a Norcross consultant hired to help develop the plan, projects that Hall’s population will rise to 372,000 by 2040, not the 561,812 estimated in the 2040 Metropolitan Transportation Plan released in 2011. The updated numbers are important because “we need to make our recommendations and our plans for our transportation network based on the most accurate data possible that we can,” said Brian Bolick, Pond vice president.
