An Arizona-based developer got the green light Thursday to get bulldozers moving again on a 53-acre Flowery Branch subdivision that had been killed by the Great Recession. Flowery Branch City Council gave its OK to a rezoning ordinance that allows Meritage Homes to revive Park Walk, a subdivision approved for up to 134 lots by the South Hall city in 2005. Construction could begin in the fall on the subdivision off Jim Crow Road between Lakeside Water Treatment Plant and Stephens Road.
