Provisions of § 450-1901 and Articles IV through XVI shall not prevent the construction of a Single Family Detached Dwelling Use B1 on any lot that was lawfully created under a previous zoning ordinance of West Rockhill Township that does not meet the lot area or lot width requirements of this chapter, subject to the provisions of § 450-1902B. However, the lot shall meet all yard requirements for the use within the applicable District.

This exception shall not apply to any two or more contiguous lots in a single ownership as of, or subsequent to, the effective date of this chapter. These lots shall be consolidated to minimize the nonconformity.

No principal building shall be erected on any part of a lot which is not as wide as the minimum required lot width specified in Articles IV through XVI, except as specified in § 450-1902 or 450-1904.

Every principal building shall be built on a lot with frontage on a public street or street improved to meet the Township's standards for public streets.

A lane lot may serve one detached single-family dwelling only.

Each lot must have a separate lane.

Lane lots may not be used in a subdivision of lots containing any new streets.

If the proposed lane lot is not large enough to further subdivide under the zoning requirements at the time the subdivision is proposed, then the "lane" shall have a minimum width of 25 feet at the street line of a public street and shall not narrow to a lesser dimension. However, if the proposed lot is large enough to further subdivide under the zoning requirements at the time the subdivision is proposed, then the minimum lane width shall be 50 feet at the street line and shall not narrow to a lesser dimension; provided, however, that should the property owner agree by plan notation and recorded document that the lot will not be further subdivided, then the lane lot of 25 feet in width shall be sufficient.

The area of the lane shall not be included in the calculation of the minimum lot area.

Only one tier of lane lots will be permitted on a tract, as determined from the street to which the lane lot takes access.

The front yard setback for a lane lot shall be a distance equal to the front yard requirements for the district in which the lot is located and shall be measured from the point where the lot first obtains the minimum lot width measurement.

The length of the lane shall be limited to a maximum length of 1,000 feet.

The improvement requirements of Chapter 365, Subdivision and Land Development, shall be met.

A subdivision of three or more lane lots will not be permitted if a public street could feasibly be constructed.

Where two lane lots are proposed in a single subdivision, access lanes should be located side by side.

Ultimate right-of-way widths are established for those roads wherein the existing legal right-of-way is less than that indicated below for the particular class of road. The center line of each ultimate right-of-way shall be considered the same center line as the existing right-of-way.

Unless otherwise specified by the right-of-way requirements of the VC Village Center and VR Village Residential Districts, streets and their future rights-of-way shall be as follows:

There shall be existing buildings on the lots on either side of the lot which would contain the proposed building.

The proposed building would front on the same side of the same street in the same block as the existing buildings on lots on either side.

The existing buildings on the lots on either side are no greater than 100 feet from the property line of the lot on which the dwelling is proposed.

The proposed building may be constructed at a front yard depth that is not less than the average of the front yard setbacks of the existing buildings on the lots on either side.

In no case shall the front yard of the proposed building be less than 20 feet.

No accessory buildings or structures shall be located in front yards. School bus shelters may be located in front yards but not closer than 12 feet to any street line.

Completely detached residential accessory buildings for residential dwellings on lots less than two acres in size and school bus shelters (provided that any of these detached accessory buildings occupy a building area of less than 120 square feet) may occupy an area of a required side or rear yard, but shall not be located closer than 12 feet to a side or rear lot line, nor closer than 12 feet to the rear or side of the principal building. All accessory buildings shall be constructed completely of a durable material and shall be neatly maintained.

Decks and patios on multifamily buildings or attached dwelling units may be located within five feet of the rear or side property line except for a side party wall line of attached dwellings, in which case the deck or patio may extend to the side party wall lot line. A fence six feet in height, and extending the length of the deck or patio along the side party wall lot line, and attached to the deck or patio, is permitted. However, decks and patios may not encroach within buffer yards or utility/drainage easements which have been established in accordance with this chapter's regulations and approved subdivisions and/or land development plans.

Decks and patios attached to single-family dwellings may project into the required minimum rear yard area no more than 15 feet. However, decks and patios may not encroach within buffer yards or utility/drainage easements which have been established in accordance with this chapter's regulations and approved subdivision and/or land development plans.

The provisions of § 450-1905 shall not apply to hedges, walls or fences, less than seven feet high above the natural grade in the required yard in agricultural or residential districts, nor to terraces, steps, uncovered unenclosed porches, nor to other similar features less than three feet above the level of the floor of the ground story.

In the case of nonresidential uses in the PC, PC-2, PI and IS Districts, the provisions of § 450-1905 shall not apply to hedges, walls or fences, less than eight feet high above the natural grade in the required yard. A fence height of eight feet may additionally have a maximum of three strands of barbed wire.

The height of buildings, as defined in § 450-201, is regulated to prevent loss of life or excessive property damage through the inability of fire equipment to reach upper stories or roofs. Therefore, no building except as provided in §§ 450-1911 and 450-1604 and Articles IV through XV shall exceed a height of 35 feet.

Residential accessory buildings shall be limited to a maximum height of 18 feet.

A walk-out basement (a basement with at-grade access to the outside of the rear of a building) shall have a maximum height of 10 feet, as measured from grade level of the basement to the average finished grade of the first floor.

Church spires, belfries, silos, water towers, smokestacks, solar panels, cellular, telecommunications facilities, wind energy facilities, wind energy conversion systems, antennas, transmission/relay tower, masts, aerials, or flagpoles may exceed 35 feet in height, subject to maximum height regulations for specific uses as may be provided for in § 450-1604, provided they are not used for human occupancy and are setback a minimum of 1.5 times their height (from ground level to the top of the structure) from a building or property line, but shall not exceed a height of 150 feet.

In all districts, no structure, fence, planting or other obstruction shall be maintained between a vertical plane two feet above curb level and a plane seven feet above curb level so as to interfere with traffic visibility across the corner within that part of the required front or side yard which is within a horizontal clear-sight triangle bounded by the two street lines (ultimate rights-of-way lines) and a straight line drawn between points on each such line 25 feet from the intersection of said lines or extension thereof. When one or both streets which form the intersection are classified as collector and arterial highways, the clear sight triangle bounded by the two street lines and a straight line drawn between points on such line shall be 50 feet from the intersection of said lines or extension thereof.

At each point where a private accessway intersects a public street or road, a clear-sight triangle of 10 feet, measured from the point of intersection of the street line and the edge of the accessway, shall be maintained, within which vegetation and other visual obstructions shall be limited to a height of not more than two feet above the street grade.

Unless otherwise specified by this chapter, minimum parking requirements for all uses listed in § 450-1604 shall be provided off-street.

The term "employee" in the minimum parking requirements is used as a measure of the number of parking spaces required. It shall refer to the maximum number of employees on duty at any time, whether the employees are full- or part-time. If shifts are involved in which two shifts overlap, it refers to the total of both shifts.

Ingress and egress for nonresidential uses shall be designed so that vehicles shall not be required to back out onto a street or another lot. Wherever possible, ingress and egress for residential uses shall be designed so that vehicles shall not be required to back out onto a street or another lot.

Parking areas for all uses except residences shall be designed to permit each motor vehicle to proceed to and from the parking space provided for it without requiring the moving of any other motor vehicle. Where possible, parking areas for residences shall be designed to permit each motor vehicle to proceed to and from the parking space without requiring the moving of any other motor vehicle.

Structures and uses in existence at the date of adoption of this chapter shall not be subject to the requirements of this section so long as the kind or extent of use is not changed, and provided that any parking facility now serving such structures or uses shall not, in the future, be reduced below such requirements.

Whenever there is an alteration of the structure or a change or extension of a use which increases the parking requirements according to the standards of this chapter, the total additional parking required for the alteration, change or extension shall be provided in accordance with the requirements of that section.

No parking area shall be used for any use that interferes with its availability for the parking need it is required to serve.

All required facilities shall be provided and maintained so long as the use exists which the facilities were designed to serve. Off-street parking facilities shall not be reduced in total extent after their provision, except upon the approval of the Zoning Hearing Board and then only after proof that, by reason of diminution in floor area, seating area, the number of employees, or change in other factors controlling the regulation of the number of parking spaces, such reduction is in conformity with the requirements of this article. Reasonable precautions shall be taken by the owner or sponsor of a use to assure the availability of required facilities to the employees or other persons whom the facilities are designed to serve. Such facilities shall be designed and used in such a manner as to at no time constitute a nuisance, hazard, or an unreasonable impediment to traffic.

Two or more uses may provide for required parking in a common parking lot if the total space provided is not less than the sum of the spaces required for each use, individually. However, the number of spaces required in a common parking facility may be reduced below this total by special exception it if can be demonstrated to the Zoning Hearing Board that the hours or days of peak parking needed for the uses are so different that a lower total will provide adequately for all uses served by the facility.

For nonresidential parking areas of three or more vehicles, the area not landscaped and so maintained, including driveways, shall be graded, surfaced with asphalt or other suitable material, and drained to the satisfaction of the Township Engineer to the extent necessary to prevent dust, erosion, or excessive water flow across streets or adjoining property. All off-street parking spaces shall be marked so as to indicate their location. Failure to keep parking areas in satisfactory condition (i.e., free from holes, clearly delineated, or properly graded) shall be considered a violation of this chapter.

On lots with a lot area of one acre or more, one school bus shall be permitted to be parked on a residential property when operated by a resident of the property. Additionally, on lots with a lot area of one acre or more, one tractor/trailer shall be permitted to be parked on a residential property when owned and operated by a resident of the property. However, no such vehicles shall be used for storage.

Attached single car garages shall not be utilized to meet off-street parking requirements for residential use as contained within the use regulations of § 450-1604 of this chapter. Attached multicar garages may be utilized to meet off-street parking requirements of this chapter less one vehicle bay.

The design of the parking lot, as indicated on the land development plan, must designate sufficient space to meet the parking requirements of this chapter. The plan shall also illustrate the layout for the total number of parking spaces.

The conditional reduction shall provide for the establishment of not less than 60% of the required number of parking spaces, as specified in this chapter. This initial phase of the parking provision shall be clearly indicated on the plan.

The balance of the parking area conditionally reserved shall not include areas for required buffer yards, setbacks, or areas which would otherwise be unsuitable for parking spaces due to the physical characteristics of the land or other requirements of this chapter. This parking area which is reserved shall be located and have characteristics so as to provide amenable open space should it be determined the additional parking spaces are not required. The developer shall provide a landscaping plan for the reserved area with the land development plan.

The developer shall enter into a written agreement with the Board of Supervisors that, additional parking spaces shall be provided at the developer's or owner's expense should it be determined by the Township that the required number of parking spaces are necessary to satisfy the need of the particular land development.

At the time of the above-stated agreement, the developer or owner may be required to provide sufficient escrow funds, with a time period to be determined by the Township, to cover the expense of installation of the additional parking if deemed necessary by the Township after the issuance of the last occupancy permit pursuant to Subsection D above. If the Board of Supervisors determine the additional spaces shall not be provided by the developer, the area shall remain as open space.

Land which has been determined and designated by the Board of Supervisors to remain open space rather than as required parking shall not be used to provide parking spaces for additional or expansion but shall remain as open space.
