The following standards shall apply to the TC Town Center District. 1142.302 Town Center Design Standards.The purpose of this Subsection is to provide guidance and direction in the development and redevelopment of lots within the Town Center Zoning District. The long-term viability of materials, visual character and sense of place of the Town Center Zoning District are important attributes to the high quality of life in our community. The design of existing and new structures shall be complementary and of high quality. The design standards have been developed for the following purposes: To ensure new development compliments the established character of the Town Center Zoning District; To set clear standards for the development and redevelopment that reinforces the small town feel and character of the Town Center Zoning District; To implement the community goals of the Comprehensive Plan; and To guide developers and property owners on expansions, renovations, or new construction. 1) Applicability. The design standards and the design review procedure per (3) below apply only to the building(s) being developed or altered including: a. All new commercial or mixed-use buildings. b. Any renovation, expansion, or exterior changes to existing commercial or mixed-use structures. i. Existing façades and building features that are not compatible with the style and period of the building shall be removed to the extent feasible. These may include, but are not limited to, wood or plastic shake mansard roofs, plastic or oddly shaped awnings, window opening infills, or surrounds designed to reduce the size of window openings, modern siding materials inconsistent with the original façade, and light fixtures inconsistent with the building’s original style or a traditional downtown aesthetic. Masonry buildings shall be cleaned as necessary to lighten the overall color. New masonry work shall match the color and materials or the original façade. Wherever practical, façade renovations shall not destroy or cover original details on a building. Brick and stone facades shall not be covered with artificial siding or panels. Original window and door openings shall be maintained wherever practical. New window and door openings shall maintain a similar horizontal and vertical relationship as the original. 2) Exemptions.

Building additions of less than 50% gross floor area. 3) Review Procedure. In addition to the site plan review information required under Subsection 1150.100 the following items shall be submitted for review and approval: a. Elevations. Complete exterior elevations of all proposed buildings and existing buildings if they are joined to new development. Elevations should be drawn at an appropriate scale (usually ¼” = 1’) and should show: i. Designations of materials and colors proposed for all exterior facades; ii. Percentage breakdown by material for each façade; and iii. Proposed style, size, and location for all signs. b. Materials Sample. Materials samples should be presented, including color and material type for all walls and roof. c. Color Samples. Samples of all principal and accent colors to be used. d.

Sloped roofs should only be used when the project abuts residentially zoned lots. Sloped roofs on projects not abutting residentially zoned lots shall only be used if concealed by a parapet or false front. 5) Screening. Utility service structures such as utility meters, transformers, above-ground tanks, refuse handling, loading docks, maintenance structures and other ancillary equipment must be inside a building or be entirely screened from abutting property views by a decorative fence, wall, or screen of plant material of sufficient height. Fences and walls shall be architecturally compatible with the primary structure. Loading docks or doors should always be located on a side or rear elevation.
