18.120.010 Purpose.

The elderly housing overlay (OV‑EH) zone is established to provide an area for elderly housing, including independent elderly housing, nursing homes, convalescent centers and assisted living centers adjacent to, or in proximity to, commercial centers, mass-transportation access, or community and civic centers. This overlay zone is not intended for hospitals, clinics, health care centers, or like uses. The OV‑EH zone may be permitted in any commercial or RM zone. The intent of this overlay zone is to provide adequate accommodation for Riverton’s elderly citizens, where the lifestyle is less burdensome and more convenient for residents to perform daily activities.
