The R-4 High-Density Residential zone is designed to implement the comprehensive plan by providing areas for high-density residential use and is intended to provide an opportunity for a dense living environment. The R-4 zone must ensure that public facilities and services will be provided in a timely manner to adequately serve the projected demand. The R-4 zone is also intended to provide a limited range of non-residential uses to help provide services for residents and enhance the quality of the high-density residential area.
