The requirements of this chapter apply to parking, access, and circulation facilities in all zones, except those specifically exempted, whenever any building is erected or enlarged, parking, access or circulation is expanded or reconfigured, or the use is changed. B. The City may require a study prepared by a qualified professional to determine offsets in parking demand, access, circulation, and other transportation impacts, pursuant to this section. C. All required parking, access, and circulation facilities shall be constructed when a use is intensified by the addition of floor space, seating capacity, or change in use, or when an existing building or dwelling is altered or enlarged by the addition or creation of dwelling units or guest rooms. D. Exceptions and Variances. Requests to depart from the requirements of this chapter are subject to chapter 18.5.5 Variances, except that deviations from the standards in subsections 18.4.3.080.B.4 and 5 and section 18.4.3.090 Pedestrian Access and Circulation are subject to 18.5.2.050.E Exception to the Site Development and Design Standards. E. Variance to Parking Standard for Commercial Buildings in the Historic District. In order to preserve existing structures within the Historic District overlay while permitting the redevelopment of property to its highest commercial use, the Staff Advisor, through a Type I procedure and pursuant to section 18.5.1.050, may grant a Variance to the parking standards of section 18.4.3.040 by up to 50 percent for commercial uses within the Historic District overlay. The intent of this provision is to provide as much off-street parking as practical while preserving existing structures and allowing them to develop to their full commercial potential. The City, through this ordinance provision, finds that reuse of the building stock within the Historic District overlay is an exceptional circumstance and an unusual hardship for the purposes of granting a variance.
