Mansions Senior Living is proposing a new 35,000-square-foot assisted living and memory care facility near its Sandy Springs residential complex on River Exchange Drive near Spalding Drive.

Mansions did not return a phone call. According to the city’s website, the plan requires rezoning. A preliminary community meeting is slated for Tues., Feb. 9 at 6 p.m. at the existing Mansions residence at 3175 River Exchange Drive.
