The meeting, sponsored by the East Cobb Civic Association, is scheduled for 7 p.m. at the East Cobb Government Center, 4400 Lower Roswell Road, Marietta. It is open to the public.
Joe Brywczynski, a WellStar senior vice president, will be the featured speaker.
WellStar is planning a 250,000-square-foot facility - about the size of a Super Walmart - on 23 acres it owns at 3624 Providence Road, near East Cobb Park.
Providence Road is a two-lane street that leads to Dodgen Middle and Walton High schools, and is surrounded by residential subdivisions. A Goodard School day-care center now sits at the corner.
Although the design is not complete, WellStar expects one building of about three stories visible from Roswell Road. Driveways will likely be on Roswell Road.
"The architects are just now beginning the preliminary site planning process, so the number of stories, as well as the number of buildings, has not yet been determined," said Keith Bowermaster, a WellStar spokesman. "However, we envision no more than a single, three-story building visible from Roswell Road with the possibility of an additional level below grade."
Current projections are for 1,250 surface-level parking spaces, though an underground garage is also possible. WellStar estimates that 350 to 700 doctors and support staff will work at the site.
The health park will likely house doctor's offices, imaging and laboratory services, a sleep center, an urgent care center and a retail pharmacy.
Last September, WellStar received approval for an outpatient surgery center there from the state department of community health in what's known as a certificate of need.
Northside Hospital, though, has challenged that certificate, and the first appeal hearing before an administrative law judge is set for the middle of April, Bowermaster said.
The outpatient surgery center is the only aspect of the health park that requires a certificate of need. Knee and ankle surgeries, tonsillectomies and Lasik eye surgery are some of the more common types of surgeries that could be performed there, according to the health system.
