The intent of this article is to strike a reasonable balance between the need or desire to display public information on signs with the need or desire to minimize visual conflicts that can occur when placement of signs is not adequately controlled. Appropriate design, placement and maintenance of signage can complement the visual appeal of the community and facilitate safe and efficient travel within the Township. Absence of appropriate standards can allow development of signage that distracts or competes excessively for visual attention or that detracts from the desirable appearance of the community.
In addition to the words and terms included in § 220-6, Definitions, pictorial descriptions of certain sign types defined in this section are provided by Exhibits XXV-1 through XXV-2.[1]
[1]
Editor's Note: Exhibits XXV-1 and XXV-2 are included as an attachment to this chapter.
A. 
No sign shall be placed, erected, altered, enlarged or relocated until a permit for doing so has been issued by the Zoning Officer. A construction permit shall also be required unless the sign proposal satisfies exemption criteria listed in Chapter 70, Building Construction and Safety Standards. Signs listed in § 220-251 herein are exempt from zoning permit requirements, provided that the use of such signs is in accordance with other provisions of this article. Applications shall be submitted on forms provided by the Township, shall indicate consent of the owner of the premises upon which the sign is to be located and shall be accompanied by supporting information that is sufficient to determine compliance with this article and any other relevant ordinances. Examples of supporting data that may be required include a scale drawing with relevant dimensions noted to illustrate the proposed height, area, size and sign copy; a plot plan of the property on which the sign will be located to illustrate the position of proposed signs relative to buildings, structures, lot lines and rights-of-way; illumination method and materials; and support systems, structural loads, stresses and anchoring details. Compliance with performance criteria may require certification by a registered design professional.
B. 
Signs and sign components may be removed for repair and maintenance, provided that they are restored to the same height, size, area and location authorized by permit. Repair and maintenance activities that do not affect the height, size, area or location of a sign do not require a zoning permit, however, if these activities affect structural or electrical components of the sign, a construction permit may be necessary.
C. 
No sign may be erected or maintained that may be confused with any authorized traffic control device.
D. 
Animated signs are not permitted in any district.
E. 
Changeable message signs are permitted in all zoning districts, subject to limitations contained in § 220-252D herein.
F. 
Every sign permitted by this article shall be kept in good condition and repair. When the Code Official determines that a sign is unsafe, unsecured, is a menace to the public or has been installed, erected or maintained in violation of any provision of this chapter, written notice shall be given to the owner of the sign, in accordance with § 220-268 herein. Said notice shall set forth a reasonable time period in which violation(s) shall be corrected. Immediate action may be required in the case of imminent danger to the public.
G. 
Any off-premises directional sign associated with a use that is no longer active, and any on-premises sign copy that no longer relates to a use conducted at the property on which it is located, except memorial signs, shall be covered or removed by the sign owner or property owner within 30 days after receipt of written notice from the Code Official, in accordance with § 220-268 herein. Any obsolete sign structure that is not reused for a new sign within one year of such notice shall be deemed abandoned. Any abandoned sign and structure and any temporary sign that is displayed beyond the permitted time limit shall be removed by the sign owner or property owner within 30 days of receipt of written notice from the Code Official, in accordance with § 220-268 herein. Upon failure to comply with a notice regarding an obsolete or abandoned sign or a temporary sign that remains in place after expiration of the display time period, the Code Official is hereby authorized to cause removal or covering of obsolete sign copy or removal of temporary and abandoned signs. Any expense incident thereto shall be assessed to the property. When an obsolete or abandoned wall sign is removed, the wall of the building or structure on which it was attached shall be restored to resemble the appearance of the wall surrounding the sign location.
A.

A. 
Any sign lawfully existing at the effective date of this chapter that does not conform to the requirements of this chapter shall be considered nonconforming, and the nonconforming use, location, area, height and/or size may be continued until such time as replacement or rebuilding becomes necessary. Replacement of copy or panels upon which copy is displayed does not constitute replacement or rebuilding of the sign, provided that the structure supporting the copy or copy panels is not rebuilt or replaced and the new copy or copy panels are not larger in any dimension than those being replaced.
B. 
When a nonconforming sign is replaced or rebuilt, the following limitations shall apply:
(1) 
A nonconforming sign damaged by fire, explosion, windstorm or other sudden natural or criminal act may be reconstructed or restored, provided that the reconstruction or restoration does not conflict with any regulation of the Commonwealth of Pennsylvania and the degree of nonconformity of the original sign is not increased.
(2) 
When the land upon which a nonconforming sign is located is taken for public purposes through eminent domain proceedings, the nonconforming sign may be relocated or replaced elsewhere on the residual property, provided that the degree of nonconformity of the original sign is not increased.
(3) 
All other nonconforming signs may only be replaced with or rebuilt as conforming signs, in accordance with all applicable provisions of this chapter.
A. 
The area of a sign shall be the area of the smallest geometric figure or the sum of the combination of regular geometric figures which comprise the sign face. The area of any double-sided or V-shaped sign shall be the area of the largest single face. Any portion of the sign face that displays a street address for the building to which the sign is associated shall not be included in the area calculation.

[1]
Editor's Note: Exhibits XXV-3 and XXV-4 are included as an attachment to this chapter.
B. 
Height.
(1) 
The height of any building sign is limited to the actual height of the building. The height limit for a freestanding sign shall be established in the specific regulations for the district in which it is located, but in no case may it be greater than the maximum permitted building height of the respective district.
(2) 
The height limit of any freestanding sign shall be measured relative to the surface elevation of the road from which the freestanding sign is intended to be viewed. If the center-line elevation of the road cartway has a higher elevation than the ground elevation at the proposed sign location, when measured along a line connecting these two points and running perpendicular to the intersecting lot line, the sign height limit may be increased by the resulting difference in elevation. If this same measurement methodology indicates that the ground at the proposed sign location has a higher elevation than the center-line elevation of the roadway from which the sign is intended to be viewed, then the sign height limit prescribed by the appropriate section within this article may not be adjusted, and any lot elevation increase achieved by mounding the proposed sign location shall be subtracted from the maximum allowable sign height. When a proposed sign will be readable from multiple roads, the greatest sign height resulting from application of this section shall be permitted.
The following signs shall be exempt from zoning permit requirements, but must conform to all other requirements of this article. Construction permits may be necessary.

A. 
General regulations for temporary signs.
(1) 
Placement, public rights-of-way. The only temporary signs permitted in a public right-of way are those classified as traffic control devices or emergency signs. They may only be installed by, or at the direction of, the authority having jurisdiction over the right-of-way.
(2) 
Placement, private property. All other temporary signs must be located on private property. In the case of off-premises temporary signs, written permission of the private property owner must be obtained, and the signs must bear the name, address and telephone number of the person responsible for placement of the sign.
(a) 
Temporary signs may be freestanding or attached to permanent buildings or structures.
(b) 
All temporary signs must be located at least 5.0 feet from any adjacent property line.
(3) 
Permits. A zoning permit shall be obtained prior to displaying any temporary sign except opinion, election campaign, real estate and on-premises residential sale signs.

Illumination. The only temporary signs that may be illuminated are on-premises commercial signs and community event signs that are located on properties used for nonresidential purposes. Illumination must be in accordance with § 220-248C.
(5) 
Durability and wind resistance. Temporary signs need not be constructed of permanent materials, but they must be constructed so that the sign and its message remain intact for the duration of the display period. The placement of a temporary sign must include a method of attachment to a structure or the ground that provides sufficient resistance to uplifting, overturning or transporting of the sign by wind forces. Freestanding temporary signs must either be fastened to a support structure that is embedded into the ground or displayed on a portable structure that is anchored to the ground.
(6) 
Height limits. Attached temporary signs may not exceed the height of the building upon which they are fastened and may not be installed as projecting signs. Freestanding temporary signs are limited to 3.5 feet in height when installed within 10.0 feet of the dedicated public right-of-way line. When installed greater than or equal to 10.0 feet from the dedicated public right-of-way line, they may be up to 6.0 feet in height if located on a property used for residential purposes, and up to 10.0 feet in height if located on a property used for nonresidential purposes.
(7) 
Off-premises outdoor advertising. These temporary sign regulations are not intended to preclude or limit the legitimate use of off-premises outdoor advertising signs, commonly referred to as "billboards."

Commercial signs. This type of temporary sign provides an opportunity for businesses to replace or supplement permanent signs on a short-term basis. They also provide an opportunity for businesses to display public information regarding special events, new products and services, changes in ownership or management, employment opportunities and similar messages. Temporary commercial signs shall be on-premises signs and must be placed and maintained in accordance with the general regulations for temporary signs. Home occupations are excluded from using this type of sign.
(a) 
Freestanding temporary commercial sign limitations.
