Hall County schools needs the dominos to fall just right in the next two years as part of its effort to accommodate growth in South Hall County. The school district announced last winter that it plans a reshuffling of schools — moving three schools back to facilities they formerly occupied — and opening its seventh high school inside the current Flowery Branch High School building. That new school, which would initially house sixth-12th grades, would use the Flowery Branch building that was built as a combination middle and high school before that plan was scrapped with the Great Recession’s slower growth.
