FORSYTH COUNTY, Ga. â The Forsyth County Commission approved a slew of updates to its conservation subdivision ordinance at its April 15 meeting that aims to preserve some undisturbed areas amid the countyâs extensive growth. Conservation subdivisions generally allow for higher residential density on a site, but as a trade-off, the developer agrees to keep more land undisturbed or provide amenities like open spaces or play fields. âWe really need this (zoning) category,â Commission Chairwoman Cindy Jones Mills said. âWe have land we need to conserve. I think it will really help reduce some of the mass grading.â The updates include calculating minimum lot sizes by average square-footage versus a set minimum that was previously included in the code on lower density residential developments. The maximum residential lot coverage was also set at 50 percent in all zoning districts. The county chose to retain its 25-acre minimum size for any conservation subdivision developments with at least 5 acres of contiguous open space.
