The following sign design principles should be used as criteria for review and approval of sign permits and Master Sign Programs.
A. Architectural Compatibility. A sign, including its supporting structure, if any, should be designed as an integral design element of a building's architecture and be architecturally compatible, including color and scale, with any building to which the sign is to be attached and with surrounding structures. A sign that covers a window or that spills over "natural" boundaries or architectural features and obliterates parts of upper floors of buildings is detrimental to visual order and will not be permitted. Common indicators of compatibility include:
1. Quality sign design and construction;
2. Proportional size and scale; and
3. Use of materials, shapes and colors that complement the building's architectural style and the surrounding environment.
B. Legibility. The size and proportion of the elements of the sign's message, including logos, letters, icons and other graphic images, should be selected based on the average distance and average travel speed of the viewer. Sign messages oriented towards pedestrians may be smaller than those oriented towards automobile drivers. Colors chosen for the sign text and/or graphics should have sufficient contrast with the sign background in order to be easily read during both day and night. Symbols and logos can be used in place of words. Substantial contrast should be provided between the color and materials of the background and the letters or symbols to make the sign easier to read in both day and night.
C. Readability. A sign message should be easily recognized and designed in a clear, unambiguous and concise manner, so that a viewer can understand or make sense of what appears on the sign.
D. Visibility. A sign should be conspicuous and readily distinguishable from its surroundings so a viewer can easily see the information it communicates.
E. Placement. Often, a building's architectural details create logical places for signage. Signs should not cover or interrupt architectural details or ornaments of a building's façade. On buildings with a monolithic or plain façade, signs can establish or continue appropriate design rhythm, scale and proportion. Well-designed and well-located retail signs create visual interest and continuity with other storefronts on the same or adjacent buildings. Signs should not obstruct windows or doors.
