A. 
Special developments are a distinct zoning district and are appropriate where a development project is proposed to be large-scale and constructed in multiple phases.
B. 
Special development designation is appropriate where a development project is proposed on a lot or, when combined, a series of lots which total at least three (3) acres in size and is unable to meet the established zoning criteria due to unusual circumstances in project size, phasing, configuration or particular design features. The special development process provides the flexibility needed to encourage efficient use of land and resources, promoting greater efficiency in public and utility services while encouraging innovation in the planning and building of a large-scale development which involves a multi-phased, multi-year timeframe.
C. 
The special development process is to enable compatible development, provide a public benefit as itemized in Section 405.1190 and achieve the following objectives:
1. 
Allow for a complex, large scale project to be phased in a manner advantageous to the City, developer and adjacent neighborhoods;
2. 
Development of a large tract of land which is vacant or underutilized in a coordinated manner;
3. 
Creation of a more desirable environment than would be possible through strict application of other City land use regulations designed for smaller projects;
4. 
Promotion of a creative approach to the use of land and related physical facilities resulting in better design and development, including aesthetic amenities;
5. 
Combination and coordination of architectural styles, building forms and building relationships covering different phases within a single development project;
6. 
Preservation and enhancement of desirable site characteristics such as natural topography, vegetation and geologic features and the prevention of soil erosion;
7. 
Preservation of buildings which are architecturally or historically significant or contribute to the character of the City;
8. 
Use of design, landscape or architectural features to create a pleasing environment;
9. 
Inclusion of special features;
10. 
Elimination of deteriorated structures or incompatible uses through redevelopment or rehabilitation; and
11. 
Facilitate implementation of the recommendations of the Business Districts Master Plan, where applicable.
