JANESVILLE Cedar Crest retirement community is finally expanding after a year in which it earned city approval and waited out the coronavirus pandemic. Cedar Crest officials decided earlier this month to proceed with their planned expansion, which will add six 10-unit apartment buildings on 9.6 acres of land between Waterâs Edge Drive and the Rock River on the cityâs south side. The development also includes multiple villa homes with a clubhouse and a pier. The Janesville Plan Commission approved rezoning for the projects last September, and the city council gave them a green light in November. The expansion also will add 24 more apartments in the Waterford Place independent apartment section of Cedar Crest and 60 assisted living and 18 memory care units in a new four-story building, all by the end of 2023.
