MEMO TO: HONORABLE MAYOR, CITY COUNCIL MEMBERS
FROM: BRUNO RUMBELOW, CITY MANAGER 19—
SCOTT WILLIAMS, DEVELOPMENT SERVICES DIRECTOR
MEETING DATE: MARCH 5, 2013
SUBJECT: AM13-01 ®® PROPOSED AMENDMENTS TO APPENDIX G,
HISTORIC PRESERVATION
RECOMMENDATION:
Council to receive public input and discuss proposed amendments to Appendix G,
Historic Preservation relative to design requirements for residential structures within
historic districts and take any necessary action.
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.

ITEM #1
These amendments were reviewed by the Historic Preservation Commission at their
December 19, 2012 and January 23, 2013 meetings. 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). Therefore, unless directed otherwise, staff will make changes to the
ordinance, notify all property owners in all historic districts as well as the Historic
Grapevine Township, and schedule another public hearing.
