Gwinnett County commissioners on Tuesday approved a change to their land-use plan that would encourage more research and development businesses along Ga. 316.

The change extended an area known as the research and development corridor east of Dacula to the Barrow County line. The shift will allow the county to better articulate its vision of Ga. 316 as a destination for technology and development companies.

The Tuesday vote will change Gwinnett County’s future development map and its planning documents to reflect that county leaders want a larger Research and Development Character Area. The expansion was made following a request at commissioners’ strategic planning session in May.

They also agreed Tuesday to extend a moratorium on applications for new adult entertainment establishments until late October, while the planning department continues to study the effects of adult entertainment. The study was originally supposed to be completed this month.
