Gainesville City Council gave its initial approval Tuesday for the Roman Catholic Archdiocese of Atlanta to proceed with building a church campus on Smith Road near the corner of McEver and Browns Bridge roads. A second and final approval is scheduled for later this month. The church campus will include a 1,000-seat sanctuary in its first phase, which could take about 14 months to complete once construction begins, and is meant to serve a growing population of Catholics in and around Gainesville.
