(1) Purpose and intent. The Township recognizes that billboards are, by their nature, different in scope and purpose from other types of signage in the Township. Among other matters, billboards advertise or communicate goods, services or messages not conducted, sold, or generated on the lot where the billboard is located. Billboards are significantly larger in size than other types of signage allowed in the Township, and their principal purpose is to dramatically attract the attention of the traveling public. The potential impact of a billboard on adjacent areas is significantly greater than other types of signage. Recently, more businesses desire to utilize advancements in technology which permit signs (including billboards) to change copy electronically (e.g., utilizing an LED or digital type of sign). These newer technologies exacerbate the potential impact of a billboard in terms of adversely dominating the environment in which they operate due to light spillover and light pollution, unless regulated in a reasonable fashion. The intent of this section is to establish size, location and operating standards and regulations for billboards, including addressing those utilizing these newer technologies, in order to minimize the secondary effects that can accompany the unregulated display of these types of signs, preserve the character and repose of adjacent areas (with a principal focus on residential neighborhoods), protect property values in all areas of the Township, and reduce traffic and similar hazards caused by undue distraction.
(2) General requirements.
(a) For purposes of this section, the words "billboard," "digital sign" and "sign" shall have the same meaning as provided in this chapter, as amended from time to time. "Digital billboard" shall mean a billboard which incorporates, in whole or in part, a digital sign.
(b) Any double-faced billboard having back-to-back surface display areas, no part of which is more than two feet apart, is considered to be a single billboard.
(c) Billboard structures having more than one surface display area which are tandem (side-by-side) or stacked (one above the other) are considered two billboards and are prohibited.
(d) The installation or use of a billboard is permitted only to the extent authorized by, and subject to, the provisions of this chapter, as amended from time to time.
(e) No billboard may be installed or erected at any time when there are 20 or more existing billboards located in the Township.
(3) Spacing.
(a) No more than three billboards may be located within any linear mile along a street, notwithstanding the fact that such billboards may be located on different sides of the street. This distance requirement shall include in its calculation any billboards located outside of the boundaries of the Township.
(b) No billboards may be located within a radius of 1,000 feet of another billboard regardless of geographic jurisdiction or within 200 feet of existing or future residential uses.
(c) If a billboard is illuminated, the minimum distance from an existing or future residential use shall be 300 feet.
(d) No billboards may be located within 75 feet of a property line adjoining a street or 30 feet of any other boundary lines of the property on which the billboard is located.
(e) All distances as provided for in this section shall be measured radially from where the surface display area is visible.
(f) No billboard may be located on top of, cantilevered over or otherwise suspended above any building or structure.
(4) Billboard surface display area; measurement.
(a) The maximum allowable surface display area for a digital billboard is 672 square feet if the sign is within 100 feet of U.S. 131. The maximum allowable surface display area for all other billboards at any location is 300 square feet.
(b) The surface display area of a billboard shall be measured to include the entire area within a regular geometric form or combinations thereof comprising all of the display area of the billboard, including all of the elements of the matter displayed. Frames and structural members, excluding necessary supports or uprights, shall be included in computation of surface display area. In the case of a sphere, spheroid, or similarly shaped billboard (e.g., a ball), the total surface display area shall be divided by two for determining the maximum surface display area permitted.
(5) Height of billboards. The height of a billboard may not exceed 35 feet above the natural grade of the ground on which the billboard is located.
(6) Illumination. A billboard may be illuminated, provided such illumination is consistent with the requirements for a digital billboard as set forth herein, or is concentrated on the surface of the billboard and is located so as to avoid glare or reflection onto any portion of an adjacent street or highway, the path of oncoming vehicles or any adjacent premises.
(7) Appearance. Except for time and temperature signs or digital billboards as otherwise regulated herein, all billboards must be stationary and may not contain any visible moving parts, alternating or moving messages or have the appearance of having moving parts or messages. Under no circumstances may any type of billboard contain a message or display that appears to flash, undulate, pulse, move, or portray explosions, fireworks, flashes of light, or blinking lights or otherwise appears to move toward or away from the viewer, expand or contract, bounce, rotate, spin, twist or make other comparable movements.
(8) Construction and maintenance. A billboard shall be constructed in such a fashion that it will withstand all wind and vibration forces that can normally be expected to occur in the vicinity and in compliance with all applicable codes. A billboard shall be maintained so as to assure proper alignment of structure, continued structural soundness and continued readability of message.
(9) Display.
(a) The display or message on a digital billboard, of any type, may change no more frequently than once every eight seconds, with a transition period of one second or less.
(b) The display or message must otherwise comply with Subsection Q(7), and the digital billboard must have installed an ambient light monitor which shall continuously monitor and automatically adjust the brightness level of the display based on ambient light conditions consistent with terms of this chapter. Since property size differs from billboard site to site, the ambient level should be measured at the property line, like we would do for site lighting.
(c) Maximum brightness levels for digital billboards shall not exceed 0.2 footcandle over ambient light levels measured within 150 feet of the sign. Certification must be provided to the Township demonstrating that the sign has been preset to automatically adjust the brightness to these levels or lower. Reinspection and recalibration shall be annually required by the Township, in its reasonable discretion, at the permittee's expense to ensure that the specified brightness levels are maintained at all times.
(d) Brightness of digital billboards shall be measured as follows:
[1] At least 30 minutes following sunset, a footcandle meter shall be used to obtain an ambient light reading for the location. This is done while the sign is off or displaying black copy. The reading shall be made with the meter aimed directly at the sign area at the preset location.
[2] The sign shall then be turned on to full white copy to take another reading with the meter at the same location.
[3] If the difference between the readings is 0.2 footcandle or less, the brightness is properly adjusted.
(10) Other applicable laws. A billboard must comply with all applicable provisions of federal and state law.
(11) Permitting. Every billboard requires a Township sign permit before installation or modification. Permits shall be reviewed and issued consistent with the terms of this section as well as all other applicable ordinances of the Township including, without limitation, this chapter, as amended from time to time. Every applicant for a billboard permit shall file with the application a certificate of insurance, certifying that the applicant is insured against bodily injury and for property damage arising out of the erection, maintenance, repair, and replacement of the billboard. Each applicant, if the permit is granted, shall be required to maintain said insurance and keep a certificate of insurance currently effective on file with the Township so long as the billboard or billboards are in existence. The certificate shall provide that the Township shall receive 10 days' written notice in case of cancellation of the policy. Any billboard in violation of the insurance requirements of this section shall be removed immediately and the cost of such removal shall be charged against the owner of the billboard.
(12) Other requirements. Billboards must otherwise comply with all other relevant regulations and ordinances of the Township.
