Mixed-Use Planned Development District
The purpose of the Mixed-Use District is to encourage the development of a compatible mixture of land uses which may include residential, retail, offices, recreational, entertainment, research oriented light industrial, water oriented or other related uses. The compatibility and interaction between mixed uses is to be insured through adoption of Master Plan (defined in subsection 30-4.20f) and development plan site plan (defined in subsection 30-4.20h), which indicate proper orientation, desirable design character and compatible land uses to provide for: A more pedestrian-oriented nonautomotive environment and flexibility in the design of land uses and structures than are provided by single purpose zoning districts, including but not limited to shared parking; The enhancement and preservation of property and structures with historical or architectural merit, unique topographic, landscape or water areas, or other features requiring special treatment or protection; Recreation areas that are most accessible to both the M-X district's inhabitants and other City residents; Environments that are more conducive to mutual interdependence in terms of living, working, shopping, entertainment and recreation; and Flexibility in the design, lay-out and timing of build-out of large-scale mixed use projects in order to respond to market demands while ensuring that development is in conformance with adopted standards, procedures and guidelines. In order to accomplish this purpose, the City may establish Development Standards, Procedures and Guidelines (which govern, among other items, processing procedures, project-wide design guidelines addressing architecture, site planning, parking, circulation, streetscape, open space, landscaping, lighting, project identification and signage, and specific use design guidelines) as part of the Master Plan to which the Development Plans must then conform.
