BACKGROUND INFORMATION: Several months ago, staff was asked to draft an ordinance that would provide the Historic Preservation Commission tools to prevent large, out of scale, and inappropriate residential structures from being built in the historic districts. The attached amendments will help to ensure that new structures and additions are compatible with the fabric of the existing neighborhoods, especially when they are next to modest vernacular homes. The proposed ordinance amends Appendix G Historic Preservation, Section 7 Certificates of Appropriateness in the Code of Ordinances. Significant elements of the amendments include: Requirement for applicant to submit drawings showing the proposed structure and showing the structures on each side of it. Height of structure not to exceed the tallest house within 300 ft, and never to exceed 35 ft. Maximum floor area not to exceed the largest house within 300 ft, but never to exceed 3,400 sq. ft. Total area of the second floor shall not exceed 65% of the area of the first floor A side yard setback plane shall be established s o t hat the maximum all height (measured at the required side yard setback), shall not exceed 14 ft in height. Beyond 14 ft in height, the structure shall slope away from the setback plane at a 45 degree angle.

At the January 23, 2013 meeting, the commission voted in favor of the changes, with a recommendation that Council adopt the ordinance. The document contains input from the Jackson Walker Law Firm, Convention and Visitors Bureau staff, Development Services, and the Historic Preservation Commission. It has been reviewed by Assistant City Attorney, Matthew Boyle. City Council reviewed these amendments at their February 19, 2013 Workshop. Following the review, City Council stated that they wanted these provisions to apply to aII residential structures not only within the historic districts, but also throughout the entire township (including commercial uses that are housed in former residential structures).
