8A retardant, longer lasting and lighter in weight than a standard roofing system. On August 14, Page 2 2007, staff brought this item to the Architectural Review Committee (information item). The committee generally supported the SSMR concept for environmental reasons, however the committee cautioned about the issues of architectural compatibility, form, details and context (Attachment 6). Since that time, staff has done extensive research on metal roofs and investigated potential alternatives. A survey of other cities was also conducted on the matter (under separate cover). Regulatory Context The Architectural Permit Process is defined in Article 45 of the Zoning Ordinance and includes general standards by which the design characteristics of specific applications, including single-family dwellings can be evaluated: . Article 45.1 states the following purpose iI...tO provide a means through architectural control to protect and enhance the natural beauty of the environment, to provide for the orderly and harmonious appearance of structures and grounds..." . Article 45.6 adds that the reason for this review process exists iI...in order to insure that the functional arrangement and the general appearance of the structures from the street or other public place will be in keeping with the purposes outlined in Section 45. 1. .. J~ . Article 45.8 sets the general standards by which applications get reviewed, more specifically the following subsection: ':...C. The extent to which the structure conforms to the general character of other structures in the vicinity insofar as the character can be ascertained and is found to be architecturally desirable. . ." Design Criteria for Standing Seam Metal Roofs for Single Family dwellings In 2002, the Zoning Administrator approved an Architectural Permit for a single-family residence which incorporated an SSMR to the overall application (Attachment 7). Staff was able to make the determination that this application was in compliance with the visual compatibility standards set forth in Article 45.8 and because the property met the following criteria: . The addition to the single family residence contained a flat roof design (where the SSMR was used). . The flat roof was not visible from the public-right-of-way and of a drab earth-tone color with a matte finish . Neighborhood visual impact of the flat roof was negligible . Quality finishing materials were used in the addition · Significant and quality landscaping was used to blend the roof into the neighborhood . There were different architectural style homes in the neighborhood . The particular home contained a blend of modern design which conformed to the neighborhood (the flat roof portion was secondary to the primary pitched roof composition of the dwelling). With the continued interest in the development of "green building" practices and promotion by metal roof manufacturers, requests from property owners, designers, architects and/or developers for the use of metal roofs in single-family residential applications are expected to increase over time. Typically, SSMR's, have been reserved for commercial and industrial areas for various uses such as commercial offices, storage facilities, auto repair operations, fast food restaurants and hotels and motels etc. One of the most obvious benefits favoring the use of SSMR's has been their ease of installation. In contrast to the concrete, clay, metal or composite tile roofs which have to be installed one tile or section at a time, SSMR's are manufactured in rolls which are precutto sheet size (typically 10 or 12 inches wide) and
