(a) Construction.
(1) The construction, erection, safety and maintenance shall comply with all applicable building codes.
(2) All signs shall be constructed in a professional manner in conformance with the appropriate building code and other applicable requirements of the City and shall be structurally sound to withstand wind pressures of at least thirty pounds per square foot of surface area.
(3) Signs shall be constructed of durable materials which are of appropriate quality and which are compatible with the materials of the building upon which such signs are placed. Wood or metal shall have a durable finish able to withstand routine environmental wear.
(4) No sign shall have more than two faces, which must be parallel to one another and within twenty-four inches, unless a specific provision of this chapter requires a lesser dimension.
(5) Electric signs and all permanent signs involving structural requirements of the building code shall be installed, repaired, altered and serviced only by a contractor licensed to perform such tasks.
(b) Placement.
(1) No sign shall be erected, relocated or maintained so as to prevent free ingress or egress, or block any light or ventilation openings. No sign shall be located or attached so as to obstruct emergency facilities or equipment.
(2) No sign shall be erected within the area of any sight triangle unless it is no greater than three feet in height and does not otherwise obstruct free and clear vision within the sight triangle.
(3) No sign shall interfere, or otherwise cause visual conflict, in whole or in part, with any authorized traffic control sign, signal or device by virtue of the placement, color, or illumination of the sign.
(4) Every sign shall be located on the same lot as the business or use to which such sign pertains; entrance and exit signs may be located off site, provided that such signs are located on drives providing direct access to the lot and parking area of the business to which they pertain.
(c) Illumination and Brightness.
(1) Artificial illumination for signs shall be concentrated on the area of the copy.
(2) Where permitted, signs that are internally illuminated and electronic message centers shall not exceed 100 candelas per square meter (cd/m2) from dusk until dawn.
(3) Signs that are internally illuminated and electronic message centers shall have a manufacturer's certification that their luminance will not exceed the
limits set forth in subsection (2) above. Certification is required to be made in conjunction with permit application pursuant to Section 1293.11 and is subject to field inspection once installed. Luminance limits are for the sign's maximum output (e.g., white screen in the case of electronic message centers) and shall be measured from a distance of thirty feet from the sign face at not more than a ninety degree angle from the sign face.
(4) No sign shall have any lights or illumination that flash, move, rotate, scintillate, blink, flicker, vary in intensity or color, or use intermittent electrical pulses.
(5) No sign shall be illuminated so as to cause objectionable brightness or glare into or onto any adjacent property or any right-of-way.
(6) Use of search lights, floodlights, and other such manner of directed light into the atmosphere is prohibited.
(d) Lighting Tubes.
(1) The use of lighting tubes is permitted on a sign solely as a design or accent element for the copy area. It may not be used as a border.
(2) No sign in excess of four square feet may be constructed solely of lighting tubes.
