As used in this article, the following terms shall have the following meanings:
ALTERATIONA change in the size or shape of an existing sign, provided that a change in the copy or color of an existing sign or the changing or replacing of a sign face or pane on an existing sign, without any change in the size or shape of the sign, is not an alteration.
ANIMATED SIGNA sign employing actual motion, the illusion of motion, or light and/or color changes achieved through mechanical, electrical or electronic means, which are differentiated from changeable signs as defined and regulated by this Code, including the following types:
A. ENVIRONMENTALLY ACTIVATEDAnimated signs or devices motivated by wind, thermal changes, or other natural environmental input. Includes spinners, pinwheels, pennant strings, and/or other devices or displays that respond to naturally occurring external motions.
B. MECHANICALLY ACTIVATEDAnimated signs characterized by repetitive motions and/or rotations activated by a mechanical system powered by electric motors or other mechanically induced means.
C. ELECTRICALLY ACTIVATEDAnimated signs producing the illusion of movement by means of electronic, electrical or electromechanical input and/or illumination capable of simulating movement through employment of the characteristics of one or both of the classifications noted below:
(1) FLASHINGAnimated signs or animated portions of signs whose illumination is characterized by a repetitive cycle in which the period of illumination is either the same as or less than the period of nonillumination. For the purposes of this article, flashing will not be defined as occurring if the cyclical period between on-off phases of illumination exceeds four seconds.
(2) PATTERNED ILLUSIONARY MOVEMENTAnimated signs or animated portions of signs whose illumination is characterized by simulated movement through alternate or sequential activation of various illuminated elements for the purposes of producing repetitive light patterns designed to appear in some form of constant motion.
AWNINGAn architectural projection or shelter projecting from and supported by the exterior wall of a building and composed of a covering of rigid and/or nonrigid materials and/or fabric on a supporting framework that may be either permanent or retractable.
AWNING SIGNA sign displayed on or attached flat against the surface or surfaces or an awning.
BANNER SIGNA flexible substrate on which copy or graphics may be displayed.
BUILDING FACADEA portion of any exterior elevation of a building extending vertically from grade to the top of a parapet wall or eaves and horizontally across the entire width of the building elevation.
CANOPY (ATTACHED)A multisided overhead structure or architectural projection supported by attachment to a building on one or more sides and either cantilevered from such building or also supported by columns at additional points.
CHANGEABLE SIGNA sign with the capability of content change by means of manual or remote input, includes the following types:
A. MANUALLY ACTIVATEDChangeable signs whose message copy or content can be changed manually on a display surface.
B. ELECTRICALLY ACTIVATEDChangeable sign whose message copy or content can be changed by means of remote electrically energized on-off switching combinations of alphabetic or pictographic component arranged on a display surface. Illumination may be integral to the components, such as characterized by lamps or other light-emitting devices, or it may be from an external light source designed to reflect off the changeable component display.
CONFORMING SIGNA sign that is legally installed in conformance with all prevailing jurisdictional laws and ordinances.
DIRECTIONAL SIGNAny sign that is designed and erected for the purpose of providing direction and/or orientation for pedestrian or vehicular traffic.
DISPLAY TIMEThe amount of time a message and/or graphic is displayed on an electronic message sign.
ELECTRONIC MESSAGE CENTER OR SIGN (EMC)An electronically activated changeable sign whose variable message and/or graphic presentation capability can be electronically programmed by computer from a remote location.
FOOTCANDLEAn English unit of measurement of the amount of light falling upon a surface (illuminance). One footcandle is equal to one lumen per square foot.
FREESTANDING SIGNA sign principally supported by one or more columns, poles or braces placed in or upon the ground.
ILLUMINANCEThe amount of light falling upon a real or imaginary surface, commonly called "light level" or "illumination." Measured in footcandles (lumens/square foot) in the English system and lux (lumens/square meter) in the SI (metric) system.
ILLUMINATED SIGNAny sign which has characters, letters, figures, designs or outline illuminated by electric lights or luminous tubes, or LED (light-emitting diode) technology as a part of the sign proper.
NONCONFORMING SIGNA sign that was legally installed by permit in conformance with all municipal sign regulations and ordinances in effect at the time of its installation, but which no longer complies with subsequently enacted laws and ordinances having jurisdiction relative to the sign.
ON-PREMISES SIGNA sign erected and maintained for the purposes of the display of commercial or noncommercial messages appurtenant to the use of products sold on, or the sale or lease of the property on which it is displayed.
OFF-PREMISES SIGNA permanent sign erected, maintained, or used in the outdoor environment for the purpose of the display of commercial or noncommercial messages not appurtenant to the use of, products sold on, or the sale or lease of, the property on which it is displayed.
PORTABLE SIGNAny sign not permanently attached to the ground and that can be removed without the use of tools.
PROJECTING SIGNA sign other than a wall sign that is attached to or projects from a building face or wall or from a structure whose primary purpose is other than the support of a sign.
ROOF SIGNA sign mounted on the main roof portion of a building or on the uppermost edge of a parapet wall of a building and which is wholly or partially supported by such building. Signs mounted on mansard facades, pent eaves, and architectural projections such as canopies or marquees shall not be considered to be a roof sign.
SIDEWALK SIGNA portable sign located on private property in front of the business it advertises.
SIGNAny device visible from a public place whose essential purpose and design are to convey either a commercial or noncommercial message by means of graphic presentation or alphabetic or pictorial symbols or representations.
SIGN AREAThe area upon which the lettering, illustration or display is presented, included within the frame or edge of a sign, including the frame. Where the sign has no such frame or edge, the area shall be computed as specified in Attachments 6, 7 and 8. The area of any double-sided or V-shaped sign shall be the area of the largest sign face only. The area of a sphere shall be computed as the area of a circle. The area of all other multiple-sided signs shall be computed as 50% of the sum of the area of all faces of the sign.
TEMPORARY SIGNA sign intended to display either commercial or noncommercial messages only displayed for a brief permitted time frame. Portable signs or any sign not permanently embedded in the ground, or not permanently affixed to a building or sign structure that is permanently embedded in the ground, are considered temporary signs.
WALL SIGNA sign that is in any manner affixed to any exterior wall of a building or structure and that projects not more than 18 inches from the building or structure wall. Signs affixed to architectural projections that are parallel to the facade are also wall signs.
WAYFINDING SIGNSA sign specifically design to provide directional or destination information.
WINDOW SIGNA sign affixed to the surface of a window with its message intended to be visible to the exterior environment.
