Developer Ethan Collier plans to convert the Hillocks Farms development in Hixson to almost all residential, adding 430 housing units.
His application with the Planning Commission lists 105 townhouses and 325 single-family homes as the initial Planned Unit Development is amended to add 110 acres.
Townhomes will occupy 25 acres and single-family homes 50 acres.
There will be 25 acres of open space.
The planned commercial section at Hillocks Farms will shrink to 10 acres.
Hillocks Farms was first announced in early 2016 by a Florida development firm. The $100 million development was to focus on high-end apartments and commercial.
The property is bounded by Highway 153, Boy Scout Road and Sandswitch Road.
The commercial will be a maximum of 75,000 square feet.
The overall density is 3.92 units per acre.
The property is the former Jack Lonas farm.
