CITY OF SANTA ANA <br />RFP NO.: 20-139 <br />DESIGN, CONSTRUCTION, MAINTENANCE AND MANAGEMENT <br />OF DIGITAL BILLBOARDS AND MANAGEMENT OF BUS SHELTERS AND STOPS <br />viii. Billboards projecting over a pedestrian walkway shall have a minimum clearance of <br />twelve (12) feet between the lowest point of the sign and the walkway grade. <br />ix. All billboards not projecting over drive areas or pedestrian walkways shall have a <br />minimum clearance of twelve (12) feet between the lowest point of the billboard and <br />ground level. <br />f. Lighting and Display Requirements <br />The following lighting and display requirements apply to the digital billboards: <br />i. Signs shall produce a maximum 0.3 foot-candles over ambient light levels. <br />ii. The display brightness shall be controlled by a photocell or light sensor that adjusts the <br />brightness to the required level based on ambient light conditions without the need for <br />human input. Use of other brightness adjustment methods, such as timer- or calendar - <br />based systems, shall only be used as a backup system. <br />iii. The display shall be factory -certified as capable of complying with the above brightness <br />standards. Such certification shall be provided to the satisfaction of the Executive <br />Director of the Planning and Building Agency, or his/her designee. <br />iv. The sign owner shall provide to the City, upon request, certification by or compensation <br />for an independent Company to verify that the brightness levels of the electronic <br />billboard are in compliance with the requirements of this Section. <br />v. All signs shall be equipped with a control system that, in the event of a display or control <br />malfunction, "freezes" the display on either a single, unchanging message, or a blank <br />screen. <br />vi. Any sign area not comprising the electronic display panel is prohibited. This area <br />includes, but is not limited to, static sign area, appendages, cutout letters, and figures. A <br />frame surrounding the display panel up to twelve (12) inches in width shall be permitted; <br />it shall not contain any sign copy or graphics and shall not count toward the sign area. <br />vii. Where screen transitions are used, such transitions shall not give the appearance of <br />moving text or images, and should use smooth effects, such as fades, rather than abrupt <br />transitions. The sign copy shall not use flashing, intermittent or moving lights or produce <br />the optical illusion of movement. <br />viii. Each sign copy shall be displayed for a minimum of four (4) seconds. The still images <br />may not move or present the appearance of motion and may not use flashing, <br />scintillating, blinking, or traveling lights or any other means not providing constant <br />illumination. Transition or blank screen time between one still image and the next may <br />not exceed one (1) second. <br />Page 5 of 18 <br />
