Such frontage shall be in accordance with that specified in the part pertaining to the particular district in which such lot is located.

In the event that a zoning district under this Part allows only one principal use per lot, the following uses shall be allowed on the same lot despite such a restriction:

A. Conversions of existing buildings in accordance with Part 26: SPECIAL PROVISIONS.
B. Single-family detached residential dwelling and agricultural use.

Minimum Lot Width. Where a minimum lot width is specified, no principal building shall be erected on any part of a lot which has a width of less than required under the applicable zoning district, except as provided in Subsection 5, below.

Exceptions to Minimum Lot Areas and Widths. The provisions of Subsections 1B and 4 shall not prevent the construction of a building on any lot in the RA and RB Districts which was lawful when created and which, prior to the effective date of this chapter, was in single and separate ownership duly recorded by plan or deed, subject to the provisions of Part 26. However, the above shall not prevent the erection of a one-family dwelling upon a lot existing on or before July 29, 1956, of less area and less minimum width at the front building line, and in such case, the total width of the two side yards may be reduced in the proportion that the width of the lot is less than 160 feet; provided, however, that no such dwelling shall be erected upon a lot having an area of less than 10,000 square feet and a width of less than 70 feet.

A. Exceptions to Minimum Lot Areas and Lot Widths in the Carversville Village Commercial (VC-C) or Carversville Village Residential (VR-C Districts. The provisions of Subsection 1B and 4, shall not prevent the construction of a building on any lot with nonconforming size or width located in any Village Commercial or Village Residential District which existed prior to June 21, 2011.

Minimum Floor Area
Except as provided in § 27-2602, Subsection 1F(5), every dwelling shall have a minimum covered and enclosed net floor area of 500 square feet excluding the areas of basements. Attached garages or similar attached structures shall not be considered in computing floor area in any case.

Narrow Lots, Standards for
All plans submitted for land development or subdivision of land shall have a well-designed street system to serve interior lots. Narrow lots are permitted only when no other practical design layout is possible, and in compliance with the Subdivision and Land Development Ordinance [Chapter 22] narrow lots provisions, including § 22-502.

Natural Resource Protection Standards
1. Natural resource protection standards shall be applied as follows:

A. Determine the site area.
B. Determine, based on the site area, all land area required to be protected under this Part, and all land area required to be kept as open space or to otherwise be protected under the Township's ordinances.

2. Setbacks from Natural Resources. Minimum building setbacks shall be measured from the limit of the below-specified protected natural resources rather than from the lot lines so that the required minimum yard is free from protected natural resources. Resources requiring these setbacks are: floodplains, wetlands, slopes of 25% or greater, ponds, and lakes. Where a conflict arises between provisions, the stricter provision shall control.

3. All areas required to be protected under this Part and all land area required to be kept as open space or to otherwise be protected under the Township's ordinances shall be restricted from future development and/or subdivision, whether through deed restriction, easement, or other instrument that runs with the land in perpetuity and puts future landowners and occupants on notice of the restrictions and land to be protected. The document evidencing the restriction shall also state whether any conditional use approval was granted under § 27-2207, and the details of such approval, including the date of the approval and approval terms and conditions. Requests to amend or alter such restrictions by future landowners to disturb natural resources protected by this Part beyond that which is permitted in the restriction shall require conditional use approval from the Board of Supervisors under § 27-2207.

See § 27-2205: Natural Resource Standards for complete, detailed information.

Noise Control
Environmental Performance Standards.

Maximum Permissible Sound Levels by Receiving Zoning District.
No person shall operate or cause to be operated on public or private property any source of continuous sound in such a manner as to create a sound level which exceeds the limits set forth for the receiving zoning category in the following table when measured at or within the property boundary of the receiving zoning district. Sound levels exceeding the limits set in the following table are hereby declared to be a nuisance.
For a table of Continuous Sound Levels Within Receiving District see table.

Standards.
For the purpose of measuring sound in accordance with the applicable provisions of these regulations, test equipment methods and procedures shall conform to the latest approved standards as published by ANSI or its approved equivalent.

Correction for Character of Sound.
or any source of sound, which emits a pure tone, the maximum sound level limits set forth in Subsection 5B(1) shall be reduced by 5dBA. For any source of sound which emits an impulsive sound, the excursions of sound pressure level shall not exceed 20dBA over the ambient sound pressure level, regardless of time of day or night or receiving land use, using the "fast" meter characteristic of Type II meter, meeting the IEC-651 and ANSI S1.4 Type 2 Specification.

Sound Measurements.
The sound meter shall be operated in accordance with the manufacturer's instructions. The sound meter shall be calibrated with each use. The sound meter shall be operated using the "A" weighting and fast response settings. Readings shall be taken in such a way that traffic noise is factored into the reading.

Excessive Noise Prohibited.
In addition to the above, it is hereby declared to be a nuisance and shall be unlawful for any person, firm or business entity to make, cause, suffer or permit to be made or caused upon a property owned, occupied or controlled by him or it or upon any public land, street, alley or thoroughfare in the Township any excessive noises or sounds, by means of vehicles, machinery, equipment (including sound amplification equipment and musical instruments) or by any other means or methods which are physically annoying to the comfort of any reasonable person or which are so harsh, prolonged, unnatural or unusual in their use, time and place, as to occasion physical discomfort, or which are otherwise injurious to the lives, health, peace and comfort of the inhabitants of the Township or any number of residents thereof.

Special Prohibitions.
The following acts and causes thereof are hereby declared to be a nuisance and in violation of this chapter:

(1) Possessing, harboring or keeping an animal or bird which makes any noise continuously and/or persistently for a period of 15 minutes or more, in such a manner as to disturb or annoy any person at any time of the day or night, regardless of whether the animal is situated upon private property.

(2) Operating, playing or permitting the operation or playing of any radio, television, audio equipment, sound amplifier, musical instrument or other such device between the hours of 10:00 p.m. and 9:00 a.m. in such a manner as to cause annoyance to persons in the vicinity.

This provision does not apply to domestic power tools or vehicles which are duly licensed, registered and inspected for operation on the public highways of this commonwealth.

(4) Repairing, rebuilding, modifying, testing or operating a motor vehicle, motorcycle, recreational vehicle or powered model vehicle in such a manner as to cause annoyance to persons across a real property boundary from the noise source.

(5) Operating or permitting the operation of any mechanically powered saw, drill, sander, grinder, lawn or garden tool or similar device used out of doors between the hours of 10:00 p.m. and 7:00 a.m. in such a manner as to cause annoyance to persons across a real property boundary from the noise source.

See § 27-25125 for complete, detailed information.

Nonconforming Buildings or Structures by Dimension
Expansions of or changes to dimensionally nonconforming buildings or structures are not permitted except to the limited extent set forth below only.

A. Expansions or changes of a totally nonconforming building or structure that has one or more dimensional nonconformity may be changed or expanded in order to fully, or more fully, conform with all applicable dimensional requirements for the zone in which such nonconforming building or structure is located. The total area of the totally nonconforming building or structure may, at the same time, be increased provided that the expanded area shall not exceed a cumulative maximum of 50% of the footprint of the totally nonconforming building or structure.

(1) Illustration. If a building or structure is located on a property in such a way that the building or structure is totally nonconforming, dimensionally (i.e., e.g., where the structure is entirely within the scenic road set-back) the building or structure may be modified to such that the nonconforming area is reduced. For example, a porch area that is encroaching into the setback by 20 feet may be modified such that the encroachment is lessened to 10 feet. If the totally nonconforming building or structure has a footprint area of 500 square feet, the total, cumulative maximum expansion shall not exceed 250 square feet. In no instance may the dimensional nonconformity be increased, meaning that the encroachment shall not be increased. Therefore, where a porch area that is encroaching into the setback by 20 feet, it may not be expanded so that any portion of the porch area encroaches 21 feet.

B. Buildings and structures with partial dimensional nonconformities, that is, if a building or structure is located on a property in such a way that the building or structure is only "partially" conforming and "partially" nonconforming, (for example where a setback line runs "through" the building or structure), the partially nonconforming building or structure may be expanded to a cumulative maximum of 50% of the footprint area of that portion of the building or structure that is partially dimensionally nonconforming, provided that no new nonconformities are created by the expansion or change. Buildings or structures with more than one floor will be permitted to expand vertically provided that the second floor has a footprint equal to, or less than the footprint of the first floor. Those areas or portions of buildings and structures with partial dimensional nonconformities that are not within the dimensionally nonconforming area may be expanded in conformity with all other limitations in this chapter without area limitations.

(1) Illustration 1. If a building with a 1,000 square foot footprint is encroaching in the side yard set back by 10 feet, with the area of encroachment being 500 square feet, the nonconforming structure may be expanded by up to 250 square feet (i.e., 50% of the 500 square feet), (not 500 square feet 50% of the total area of the building including the conforming areas), provided that the expansion stays within the existing ten-foot encroachment and all other limitations in this chapter are also met.

(2) Illustration 2. If a building with a 1,000 square foot footprint has a second floor, each of which is encroaching in the side yard set back by 10 feet, with the area of encroachment being 500 square feet, each floor of the nonconforming structure may be expanded by up to 250 square feet (i.e., 50% of the 500 square feet per floor) provided that the expansion stays within the existing ten-foot encroachment and all other limitations in this chapter are also met.

(3) Illustration 3. If a building is encroaching in the front yard set back by 10 feet, the rear portion of this partially nonconforming structure may be expanded without limitation in area so long as the expanded area is in total conformity with all other limitations in this chapter.

C. No expansions or extensions otherwise permitted hereby may be made within or into dimensionally restricted areas if the expansion will be in greater violation of the dimensional limitation.

(1) Illustration 1. If a building is encroaching in the side yard by 10 feet, a proposed expansion of the nonconforming structure shall be prohibited if the expansion will encroach greater than 10 feet even if the maximum expansion has not been met or exceeded.

(2) Illustration 2. If a building encroaches into a ten-foot side yard by two feet, no expansion can encroach further than two feet.

D. A building or structure that is dimensionally nonconforming because of its height shall not be expanded to increase its height.

E. Any expansion of a structure that has multiple floors will be reviewed on a floor by floor basis for conformity.

(1) Illustration 1. If a nonconforming building encroaches by 10 square feet on each of three floors, the building may not be expanded by more than five square feet on each of the three floors; the total expansion cannot be accumulated and the total of 15 square feet of expansion cannot be applied to one or two floors of the structure. Each floor is to be examined separately and has a cumulative maximum expansion of five feet per floor.

F. A lot or parcel of land that is nonconforming by number of dwelling units may not be expanded with the addition of a building or structure containing more dwelling units.

Nonconforming Lot by Area or Width
A nonconforming lot or parcel of land by area or width may not be expanded by consolidation with other parcels, provided, however, that a nonconforming lot by area or width may be consolidated with other contiguous parcels in order to more fully conform with the applicable requirements for area or width regulations for the zone in which such lot or parcel is located even though the resultant lot is still not conforming.

Nonconforming Uses
A. A nonconforming use conducted entirely outside of a building or structure shall not be changed to another nonconforming use.

B. A nonconforming use that is partially or completely conducted within a building or permanent or temporary structure or building may be changed to another nonconforming use by way of a special exception granted by the Zoning Hearing Board, upon proof that the proposed new use will be no more detrimental to its neighborhood and surroundings than the use it is to replace. In determining relative "detriment," the Zoning Hearing Board shall take into consideration, among other things: traffic generated; sanitary sewage disposal; parking requirements; nuisance characteristics, such as noise and the emission of odor, dust and smoke; fire hazards; the hours and manner of operation; water consumption and any other issues deemed to be in the public interest. Any applicant for a special exception shall have the affirmative burden of proving that there shall be no detriment to the proposed change and shall present evidence addressing traffic generated; sanitary sewage disposal; parking requirements; nuisance characteristics, such as noise and the emission of odor, dust and smoke; fire hazards; the hours and manner of operation; water consumption and any other issues deemed to be in the public interest. The applicant shall further provide proof that there shall be no additional burden on existing infrastructure within the Township or services provided by other governmental entities. All other changes of nonconforming uses that are partially or completely conducted within a permanent or temporary structure or building are expressly prohibited.

C. Expansions. The nonconforming use of a building, structure or parcel of land may be extended or expanded by no more than a total of 50% of the total area of the building, structure or parcel of land that was exclusively used in a nonconforming fashion at the time the nonconformity first arose. Areas of buildings, structures or lot or parcels of land not exclusively used in a nonconforming fashion shall not be considered in the calculation of the maximum expansion. All dimensional limitations on the expansion of the use, including setbacks and buffers shall be fully respected. This is a cumulative maximum.

(1) Illustration 1. In a 1,000 square foot building, where 100 square feet is devoted exclusively to a valid nonconforming use, the total area so used, in whole or in part, on all floors of the building, may be expanded a total maximum of 50 square feet so that the cumulative total of area devoted to a valid nonconforming use is a total of 150 square feet.

(2) Illustration 2. On a one acre parcel of land, with 1/2 acre of the land totally devoted to a valid nonconforming use, the area devoted to the nonconforming use may be expanded by a maximum of 1/4 acre, for a cumulative total of 3/4 acre that may be used in a nonconforming fashion. The expansion of the area may not be made onto adjacent parcels of land even if the parcels have common ownership and common nonconformity and all dimensional limitations on the expanded use, including set-backs and buffers, shall be fully respected.

(3) Illustration 3. A one acre parcel of land totally devoted to a nonconforming use may not be expanded to adjacent parcels of land even if the parcels have common ownership.

Abandonment. If a nonconforming use of a building or land is voluntarily abandoned and ceases for a continuous period of one year, or more, as determined by the Zoning Hearing Board, all subsequent uses of such building, structure or land shall be in conformity with the provisions of this chapter.

(2) The release of air-borne toxic matter shall not exceed one-thirtieth of the threshold limit value beyond a district boundary line of the district in which the use is located.

Traffic Control
A. No activity shall occur which would adversely affect traffic flow and/or present traffic controls within the Township by creating a level of service below that which is specified in this subsection.

B. To minimize potentially adverse conditions, the level of service for traffic along any road within 1,500 feet of the points of ingress and egress of a tract or lot shall be a level of service "C" or better. The term "level of service" and the categories thereof are used herein in accordance with the definitions or meanings ascribed thereto in the document entitled: Trip Generation, An Institute of Transportation Engineers Informational Report (most current edition).

C. The determination of levels of service shall be made after an experienced Transportation Engineer/Traffic Consultant conducts a traffic study, the cost of which shall be borne by the owner of the tract or other property owner. Said study shall be based in part on the aforementioned report, and in part on the Pennsylvania Department of Transportation Handbook of Vehicle Code Regulations, in particular the following chapters: 471-610 pertaining to Engineering and Traffic Studies; 471-611 pertaining to Maintenance and Protection of Traffic; and, 471-615 pertaining to Official Traffic Control Devices. Said study shall indicate compliance with the requirement for a level of service "C" or better as set forth above, and shall include the data upon which the conclusions of said study are based, including, without limitation, traffic counts, the hours thereof, the dates thereof, and the types of motor vehicles comprising such counts.

D. Any activity which would result in a level of service below "C" shall be considered deficient and shall not be permitted unless improvements are made to the streets and/or intersections which raise the level of service to "C." The improvements shall include, but not be limited to, the following elements: internal circulation design, site access location and design, external street and intersection design and improvements, traffic signal installation and operation, including signal timing.

Vegetation
Disturbance of vegetation shall be in compliance with all applicable provisions of this chapter. The purpose of this chapter is to provide reasonable controls governing the disturbance of vegetation associated with all site alterations, grading, filling or clearing of vegetation and all subdivision and land development activities. The following standards shall apply to all vegetation disturbance.

(1) No more than 20% of vegetation shall be disturbed. The Board of Supervisors, in their sole discretion, may grant conditional use approval to no more than 50% of vegetation to be disturbed, provided that the additional vegetation disturbance is offset by additional preservation of productive agricultural soils. All requirements of the Landscape Conservation and Improvement Plant shall be met.

(2) All wooded areas which are required to be preserved shall remain in their natural condition with the natural forest understory and ground cover left intact.

(3) Wildlife Habitat. Wooded areas and/or specimen trees providing habitat for threatened and/or endangered species shall not be disturbed and shall be contained within a tree protection zone.

(4) Should any existing viable vegetation within the tree protection zone be irreparably damaged during construction or site preparation activities and, as a consequence thereof, die within two years of the conclusion of construction or site preparation activities, such trees shall be replaced in accordance with § 22-5201L, of the SALDO [Chapter 22: Subdivision and Land Development], whether or not an application for subdivision or land development is required.

(5) The removal or destruction of each viable tree within the tree protection zone is prohibited without approval from the Township or its appointed representative.

(6) Tree Replacement. Compliance with the requirements of the tree replacement provisions of § 22-520, Subsection 1L, Landscape Conservation and Improvement Plans, of the Subdivision and Land Development Ordinance [Chapter 22] shall be required when a zoning permit is issued for a building, structure, or use affecting an area greater than 2,000 square feet.

See § 27-2205: Natural Resource Standards for complete, detailed information.

Vibration Control
A. Vibration shall be measured at or beyond any adjacent lot line or residential district line as indicated in Table 27-25-1 below and such measurements shall not exceed the particle velocities so designated. The instrument used for those measurements shall be a three component measuring system capable of simultaneous measurement of vibration in three mutually perpendicular directions.

B. For maximum vibration values, see table.

C. For Maximum Ground Transmitted Vibration information, see table.

See § 27-25126 for complete, detailed information on vibration control.

Wetlands
(1) Wetlands perform the following functions:

(a) Serving natural biological functions, including food chain production; general habitat; and nesting, spawning, rearing and resting sites for aquatic, waterfowl or land species.
(b) Providing areas for study of the environment or as sanctuaries or refuges.
(c) Maintaining natural drainage characteristics, sedimentation patterns, salinity distribution, flushing characteristics, natural water filtration processes, current patterns or other environmental characteristics.
(d) Shielding other areas from wave action, erosion or storm damage.
(e) Serving as a natural storage area for storm and flood waters.
(f) Providing a ground water discharge area that maintains minimum base flows.
(g) Serving as a prime natural recharge area where surface water and groundwater are directly interconnected.
(h) Preventing pollution by not only filtering and removing pollutants, but also by assimilating and recycling them.
(i) Providing recreation.

(2) Wetlands shall not be altered, graded, developed, filled, piped, diverted or built upon. All requirements of Chapter 22: Subdivision and Land Development shall be met for wetland delineation.

(3) Crossing of wetlands is permitted as a conditional use provided that the crossing is designed so that disturbance, filling, and grading are the minimum needed to span the wetlands areas.

(4) The provisions of the Riparian Corridor Overlay District in § 27-2208: Riparian Corridors of this chapter shall apply in addition to the regulations set forth herein.

(5) Requirements for Exceptional Value Wetlands and Other Wetlands. Exceptional value wetlands deserve special protection.

(a) Exceptional value wetlands are those wetlands that meet one or more of the characteristics set forth in 25 Pa. Code § 105.17(1)(i) through (v).

(b) Exceptional value wetlands are subject to the following regulations: No disturbance or encroachments are permitted. An assessment of potential wetland impacts shall be required for any development located within 300 feet of exceptional wetlands and 100 of other wetlands because of the interconnectiveness of the landscape, the dependence of wetland functioning on the nearby upland area and the substantial potential for disturbances in reasonable proximity of a wetland. Disturbance of any area within 300 feet of exceptional value wetlands shall be prohibited where such disturbance would have a substantial adverse impact on the quality of the wetlands (see 25 Pa. Code §§ 105.14(b) and 105.15 for determination of adverse impact). All wetlands, regardless of size or quality, are an important part of the water budget based planning.

(c) All Other Wetlands. Disturbance of any area within 100 feet of other wetlands shall be prohibited where such disturbance would have a substantial adverse impact on the quality of the wetlands (see 25 Pa. Code § 105.14(b) and 105.15 for determination of adverse impact).
