Zoning
CPS-4
Intensive Mixed-Use Phased Bayside Commercial District
The commercial performance standards districts are designed to accommodate a range of business, commercial, office and hotel uses, as well as medium to high density residential development pursuant to performance standards which control the permissible type, density or intensity, and mix of development. Performance standards development will allow for modification of requirements affecting certain individual lots; greater flexibility, particularly for large-scale development; large commercial, medium to high density residential and mixed use developments in phases over time where the overall development at a single point in time or in a single instance by private owners would not be practical; providing incentives for provision of certain amenities and for conformance with specified objectives, thereby encouraging more flexible and innovative design and development in accordance with the goals and objectives of the comprehensive plan and the redevelopment plan.
