The preparation of a Specific Plan, and concurrent Zoning and General Plan Amendment(s), may be started by an applicant or property owner. The use of a Specific Plan is appropriate where site-specific regulation would be beneficial based on site features or unique characteristics of the property, such as infill and unusually configured sites. Such properties will benefit by a Specific Plan designation to facilitate innovative development in the form of buildings, construction, design, or use combinations otherwise not achievable inconsistent with the established provisions of this section.
