§ 161.242 DEFINITIONS.
   ABANDONED SIGN. A sign that no longer identifies or advertises an ongoing business, product, location, service, idea, or activity conducted on the premises on which the sign is located or a sign having no sign copy or a sign in disrepair or an off-premise sign for which the permit has expired.
   ALTERATION. A change in the size, height, or shape, or type of an existing sign. A change only to the copy or color of an existing sign is not an ALTERATION. Changing or replacing a sign face or panel is not an ALTERATION if no change in size, height, or type accompanies said change or replacement.
   ANIMATED SIGN. A sign employing actual motion, the illusion of motion, or light and/or color changes achieved through mechanical, electrical, or electronic means. ANIMATED SIGNS, which are differentiated from changeable signs as defined herein, include the following types:
      (1)   ENVIRONMENTALLY ACTIVATED. Animated signs or devices motivated by wind, thermal changes, or other natural environmental input. Said signs include spinners, streamers, pinwheels, pennants on a string, and/or other devices or displays that respond to naturally occurring external motivation.
      (2)   MECHANICALLY ACTIVATED. Animated signs characterized by repetitive motion and/or rotation activated by a mechanical system powered by electric motors or other mechanically induced means.
      (3)   ELECTRICALLY ACTIVATED. Animated 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:
         (a)   FLASHING. Animated 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 non-illumination. For the purposes of this ordinance, flashing will not be defined as occurring if the cyclical period between on-off phases of illumination exceeds four (4) seconds.
         (b)   PATTERNED ILLUSIONARY MOVEMENT. Animated signs or animated portions of signs whose illumination is characterized by simulated movement through alternate or sequential activation of various illuminated elements for the purpose of producing repetitive light patterns designed to appear in some form of constant motion.
   ARCHITECTURAL PROJECTION. Any projection from a building that is decorative and/or functional and not intended for occupancy and that extends beyond the face of an exterior wall of a building but that does not include a sign, sign face, or sign copy as defined herein.
