I finally heard back from the county as to WHY I would be isolated and earmarked for future suburban development in their 2045 Land Development Plan.

Who would like to read this document with me to find out why only my farm is earmarked for this? Document can be found at this link: https://www.gwinnettcounty.com/web/gwinnett/departments/planningdevelopment/services/landuseplanning/2045unifiedplan
