Developers broke ground yesterday (Wednesday) on a much-discussed new senior living community in Great Falls. Slated to open in the summer of 2022, The Residence of Colvin Run at 1131 Walker Road will be a 53,000 square-foot facility set on 2.8 acres. It’s about a half-mile from the Colvin Run Mill historic site. The senior living facility will offer 62 single and double occupancy units for adults 65 and older. That includes 44 assisted living apartments and 18 memory care residences. Amenities will include an art studio, a theater designed for the hearing-impaired, several dining venues, an open-hearth brick oven, and a trail connecting to neighborhood businesses.
