• Roofs and Parapets: Slope and planes. The 2012 Housing DG establish only guidelines regarding roofs and parapets. The proposed amendments establish two standards: (1) multifamily development up to 40 feet in height provide a roof sloped greater than 3-inches to 12-inches at the perimeter of the building and these sloped roof areas must be provided at a minimum length of at least 60 percent of the length of the building perimeter; and (2) roof planes must be subdivided to correspond to variations in building massing with use of bays, gables, dormers, and strong eave elements. • Materials and Character: Inside corner. "Materials and character" is another topic where the 2012 Housing DG provide only guidelines, and the proposed amendments seek to establish standards, while also maintaining some guidelines. The proposed amendments would require that changes in building wall material or color occur at inside corners (instead of side corners). A diagram to illustrate an inside corner has been added. • Materials and Character: Trim/architectural molding and high-quality materials. The standards would require trim and architectural molding to be made from a different material than the surrounding wall. Secondly, high-quality materials such as brick, stone, masonry, tile, and architectural panels would be required for at least two percent of the total exterior area of all exterior facades and for at least 20 percent of ground- floor exterior facades. • Mixed-use and Live/work Active Frontages: Visibility. The proposed amendments would add a requirement of mixed-use storefronts to be glazing for a minimum of 75 percent, allow up to 20 percent of the cumulative window area to be frosted or fritted, require that the average window sill height not exceed two feet from adjacent grade; and require that interior partitions greater than four feet in height be setback at least 10 feet from exterior glazing. • Form, Proportion, and Scale: Significant architectural element. The 2012 Housing DG include a section called, Gateway Corners, that includes design guidelines related to buildings located on, for example, the corner of two public streets. This section is proposed to be called, Form, Proportion, and Scale, and would establish a standard that would require buildings provide a "significant architectural element4" when located: (1) at the corner of two public streets; (2) at any terminus of a paseo connecting to adjacent properties; and (3) at the terminus of a viewshed extending greater than one block beyond the limits of the project site. • Building Signage: Type of signage. The proposed standard would prohibit box signs and backlit signs and require that interior signage obstruct no more than 20 percent of window area. • Compatibility with Surrounding Development: Development guidelines. The 2012 Housing DG include guidelines regarding compatibility with surrounding development. 4 Defined in the proposed glossary as: (1) a corner tower or elevated corner roof volume that is at least five feet taller than the adjacent building elements; (2) an open space plaza dedicated for public use that has a minimum dimension in each direction of 10 feet; or(3) a change in architectural features, including change in materials, window patterns, or building facade plane.
