General standards and criteria for signs.
The regulations of this section specify the area and heights of signs that are allowed within the Township and which require a permit.
A. Determination of sign area. The following criteria shall be used to determine the area of a sign:
(1) The entire face of the sign (one side only) including all lettering, wording, and accompanying designs and symbols, together with the background, whether open or closed, and any framing, bracing, or wall work incidental to its decoration shall be included (see Figure 9-12).

(2) Where a sign structure has more than one sign face, one sign face shall be used to calculate the sign area. Where sign faces on the same sign structure differ in size, the largest sign face shall be used to determine the sign area.
(3) Where the sign face consists of individual raised and/or recessed letters, logos, symbols, and/or graphics, the sign area shall be the area of the smallest rectangle that can encompass those letters, logos, symbols, and/or graphics (see Figure 9-13). Where the sign consists of a sign face of irregular shape, the sign area shall be the area of the smallest rectangle that can encompass the sign face, background, and frame. However, if a sign is a perfect circle, the sign shall be allowed to be measured based upon the square feet within the circle. An irregular sign may be measured based upon two rectangles. Such calculation shall also apply to a sign placed on a canopy or awning.

Sign Area = total width multiplied by total height within a rectangle.
In the above examples, the sign area would be A multiplied by B, and C multiplied by D.
B. Determination of sign height. Sign height shall be based upon the vertical distance from the "grade level" (as defined by this article) and the total height of the sign. If a sign is directed towards an adjacent street and the nearest segment of that street has an elevation of pavement that is more than 10 feet higher than the grade level under the sign, then the sign height may be measured from that elevation of pavement.
General sign requirements.
All signs shall meet the following additional requirements:
A. Sign materials and construction. All signs shall be constructed and installed in compliance with the current construction code(s).
B. Maintenance. Every sign, including signs that do not need a permit, shall be maintained in good repair and in a safe, clean, and attractive condition.
C. Design. Except as otherwise allowed herein, no part of a sign or other commercial display shall contain or consist of pennants, ribbons, streamers, spinners, or other similar moving, fluttering, or revolving devices. No sign shall utilize mechanical movement or sequin or sparkle effects, unless otherwise allowed by this article.
(1) Fluorescent and/or neon signs. No sign shall be permitted that is comprised of exposed fluorescent tubing or neon or similar lighting, except that an allowed principal commercial use may have a single neon sign if it is located in a window in compliance with this article and where allowed under Schedule I (see § 090-080A).
(2) Sign emissions. No sign which emits smoke, visible vapors, particles, sound, or odor shall be permitted.
(3) Sign projections. Except as otherwise permitted by this article (such as for a projecting sign), signs shall have no projecting elements greater than 18 inches.
(4) Mirrors. No mirror-type device shall be used as a part of a sign.
(5) Holographic images. Signs shall contain no parts that are holographic or that are able to produce any holographic image.
(6) Clear sight triangle. No sign shall be located within a clear sight triangle or shall otherwise create a traffic visibility hazard.
D. Setbacks and signs in the right-of-way and on public property.
(1) Except as otherwise permitted by this article, all signs shall be set back at least 10 feet from a street right-of-way line, or from a street cartway where a right-of-way line does not exist. Only official governmental signs and signs authorized under PennDOT regulations to be located within a public right-of-way shall be allowed within a public right-of-way.
(2) Public property.
(a) A person or nongovernmental entity shall not post any sign upon public property without written permission from the governmental entity that owns or controls that property, except for customary information utility companies place on utility poles. Political and commercial advertising signs shall not be allowed on public property except for:
[1] Political signs on election days where allowed outside of a polling place; and
[2] Signs authorized by a governmental entity to recognize a sponsor of a festival or recreation association, provided such signs are not designed to be readable from a public street or dwelling.
(b) A sign posted on Township property or within a public street right-of-way without governmental permission may be removed and discarded.
(3) Freestanding signs of more than 10 square feet in sign area shall be set back a minimum of 10 feet from any adjacent lot line of a lot that is not in common ownership with the lot where the sign is located.
E. Signs on private property. No person shall post a nongovernmental sign upon private property without permission from the property owner. A nongovernmental sign posted on private property without permission of the property owner may be removed and discarded by the property owner or his/her designee.
F. Signs and traffic safety. All signs shall meet the following minimum traffic safety standards:
(1) No sign shall be erected so as to obstruct any of the following:
(a) The clear sight triangle at any street intersection;
(b) Safe sight distances at vehicle driveways; or
(c) Views of a traffic control sign or a traffic signal.
(2) No signs or outdoor graphics shall by color, location, or design resemble or conflict with traffic control signs or traffic signals.
Sign illumination.
Sign illumination applies to all signs and shall be subject to the following regulations:
A. Prohibited sign illumination. The following types of sign and graphic illumination are prohibited in all areas:
(1) Bare bulb illumination;
(2) Flame illumination; and
(3) Beacons or strobe lights.
B. Types of sign illumination.
(1) Indirect illumination. Indirect illumination of signs is permitted in all districts.
(2) Internal illumination. Internal illumination of signs is permitted only in C1, C2 and I districts. Where allowed, internal sign illumination shall involve one of the following methods:

(3) Floodlight illumination. Floodlight illumination is permitted only in C1, C2 and I districts.
C. Regulations on sign illumination, electronically changeable message signs, and movement of signs.
(1) Lighting shall be aimed and shielded so that no light directly shines on residential properties.
(2) Lighting shall be aimed and shielded so that no light shines in the eyes of motorists or pedestrians.
(3) The lighting shall not be located more than 15 feet from the sign.
(4) Shielding shall be provided to prevent glare. All sign illumination must comply with regulations of this article regarding glare. See §
100-080.
(5) On-premises signs may be illuminated whenever a business is open plus 1/2 hour prior to opening and 1/2 hour after closing; provided, however, there shall be no restriction on illumination necessary for the security and/or safety of the facility in question and its premises.
(6) Signs shall not include electronically or digitally moving or flashing or animated or flickering images or letters. Electronically changing messages shall not change more often than once every 15 seconds, except that signs with an electronically changing image of more than 30 square feet shall not change more often than once every 30 seconds. An off-premises sign shall not be an electronically changeable message sign.
(7) An electronically changeable message sign shall not have an illumination level between sunset and sunrise of more than 250 nits, except the maximum level shall be 150 nits if such sign is a pre-existing nonconforming sign located in any zoning district other than the C1, C2 and/or I district. The maximum luminance between sunrise and sunset shall be 5,000 nits. Such sign shall have a light-sensing device that will automatically adjust the brightness of the display as the natural light conditions change, to comply with this lighting level. Prior to receiving a final permit for the sign, the applicant shall provide written evidence from a qualified independent professional that these maximum lighting levels are being met. The qualifications of such professional shall be submitted in writing.
(8) No two electronically changeable message signs shall be spaced less than 500 feet apart along any public road within the Township. The spacing requirement applies to signs located on both sides of the road.
(9) Maximum sign area for an electronically changing message sign is 40 square feet per face.
(10) No more than one electronically changeable message sign shall be permitted per lot, subject to the restrictions and requirements of this chapter.

On-premises signs.
Sign bonus for signs that appear to have relief-cut wood. The maximum sign area for any sign may be increased by 20% for a sign that has an appearance of relief-cut wood, and which is not internally illuminated. (Note: The Construction Code may require the use of artificial materials for fire safety purposes.) This sign bonus and the sign bonus provided in Subsection
C may be added together if the requirements for each are met.
