Where a minimum lot width is specified in the applicable district regulations or other regulations of this chapter, no principal building or use shall be erected or established on any part of a lot which has a width less than is specified.

The lot width for a single-family semidetached dwelling or end unit of townhouses shall be measured from the side lot lines to the center line of the wall in common with an adjoining dwelling.

Existing nonconforming lots. In any district where a nonconforming lot exists as a separate entity at the time of passage of this chapter and where the owner of the nonconforming lot does not own an adjoining lot, then the following development is permitted:

Height limitations. District height limitations for church spires, cupolas and domes, monuments, water towers, chimneys, smokestacks, antennas, farm structures, silos and flag poles may extend to a maximum height of 150 feet. Required utility and radio and television station transmitting or receiving towers which are permitted under the requirements of this chapter may exceed the district height limitations by 35 feet. Although exempted from structural height limitations, these structures should not impair solar access of buildings or solar collector locations.

Front yard exception. When an unimproved lot is situated between two improved lots, each having a principal building within 25 feet of the side lot line of the unimproved lot, and where the lot is not located on a major state or federal highway, then the required front yard may be reduced to a depth equal to that of the greater front yard of the two adjoining lots; provided, however, that it may not be reduced to below 15 feet in Residential Districts R-1 and R-2.

Projections into yards. Projections into required yards may be permitted as follows, except that no such projection shall be located closer than three feet to any side lot line or 10 feet to any rear lot line or 15 feet to any front lot line, except as may be provided for in § 170-92 for existing nonconforming lots:

Changes to conforming uses and buildings. Any conforming use or building may be repaired, maintained, restored or rebuilt up to the same dimensions existing at the time of the effective date of adoption of this chapter.

Any enlargement of an existing conforming use or structure on the same lot must comply in all respects with the regulations of this chapter.

In all districts, no structure, fence, planting or other obstruction shall be maintained between a horizontal plane two feet above curb level and a horizontal 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 (rights-of-way) 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 or 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.

Where, in the opinion of the Borough Engineer, the literal application of these standards in certain cases would work undue hardship or be plainly unreasonable, the Borough Engineer may recommend to the Borough Council such reasonable exceptions as would not be contrary to the public interest. The Borough Council may modify or adjust the standards to permit reasonable utilization of property while securing substantial conformance with the objectives of the regulations.

The standards included in these regulations are minimum design requirements. The Borough Council reserves the right, in any case, to request that the requirements listed herein exceed these standards if conditions so warrant.

Nonconforming uses. Whenever there is a nonconforming use, the nonconforming use must comply with the most restrictive landscape requirements for either the land use or the zoning district in which it is located or the zoning district which would normally permit the nonconforming use.

A minimum of one deciduous shade tree shall be required for every 10 off-street parking spaces.

Where a parking lot is to include 30 or more parking spaces, a maximum of 15 parking spaces shall be permitted in a row with a landscape island of 15 feet in width. Where required, this island shall contain not less than 290 square feet of planting area.

The use of salt tolerant species is encouraged.

When parking areas are located within 100 feet of a public street, the perimeter of the parking area that is adjacent to the public street shall be softened by a continuous low hedge around the outside perimeter. Required softening or screening buffer shrubs may be used to meet this requirement, so long as the hedge is to be located within the area where the buffer yard is required.

Shade trees: (2 1/2 to 3 inches caliper minimum) 14 to 18 feet high, eight feet minimum spread, clear trunk to seven feet zero inches above the ground and full branching structure.

Evergreen trees: minimum eight feet high, four feet minimum spread (NOTE: Spread may be less than four feet for upright or columnar varieties.) single leader, symmetrically branching to the ground.

Ornamental/flowering trees: minimum eight feet high, five feet minimum spread, symmetrically branched to within four feet from the ground.

Deciduous shrubs: 30 inch minimum height, twenty-four inch minimum spread and symmetrically branched to the ground.

Evergreen shrubs: twenty-four-inch minimum height, eighteen-inch minimum spread and symmetrically branched to the ground.

Ground cover plants:

Any person, corporation, firm or association intending to erect a fence shall, before work is commenced, make application to the Code Enforcement/Zoning Officer as required below and by this chapter, and no work on such a fence shall be commenced before receipt of a permit from the Code Enforcement/Zoning Officer.

Fences may be either a natural living fence or a fabricated materials fence, as defined in Article III.

Well-maintained and safe trees, shrubs or hedges and other appropriate plant material which do not constitute a natural living fence, as defined herein, and which are designed to enhance the livability and attractiveness of any lot may be located in any yard or court, provided that they do not encroach on adjoining properties or uses.

All fences shall be located completely on the owner's property and shall not overlap property lines. Fence designs and locations must permit the fence to be maintained completely from the owner's side of the property.

Location of property lines will be the responsibility of the applicant to verify, through a surveyor's account, the precise location of the lines.

All fences shall be designed and constructed to serve as permanent fences which are solidly constructed and which are capable of resisting the effects of weather and which are permanently affixed in place, except as provided below.

The following fences or fencing materials are specifically prohibited:

All chain link fences erected shall be erected with the closed loop at the top of the fence.

All entrances or gates shall open into the property.

All fences or walls must be erected so as not to encroach upon a public right-of-way or easement.

If the fence is wood cover on wood frame, the framework must face onto the interior of the lot, unless the fence is designed to provide equal frame and cover area to adjoining yards.

If the fence is open metal mesh, supported by posts and frames of either pipe or wood, the posts and frames must be on the interior of the mesh.

If the fence is of masonry construction, a finished surface must be provided on the exterior side.

Such change shall be permitted only as a special exception by the Zoning Hearing Board.

The applicant shall show that a nonconforming use cannot be reasonably be changed to a conforming use.

The applicant shall show that the proposed change will be less objectionable in external effects than the existing nonconforming use with respect to:

General nuisances. Upon a complaint registered by the Zoning Officer from 50% of the property owners within 200 feet of a nonconforming use which is considered to be a general nuisance or a hazard to the health, safety, welfare and morals of persons residing or working in or using the area, the Council shall hold a hearing and make a finding with respect to the nuisance or hazardous condition which exists and shall determine the necessity of terminating such nonconforming use. Such uses shall be terminated within such reasonable time as shall be determined by the Council after consideration of the time required for the reasonable amortization of the capital investment in such uses or as may be provided for by the laws of the Commonwealth of Pennsylvania.

Advertising signs. All nonconforming advertising signs shall be terminated within two years of the adoption of this chapter.

The exact purpose, nature and location of the proposed temporary use, including all private and public lands and rights-of-way involved.

The relationship of the temporary use to other uses permitted in the zoning district.

The number of employees, spectators, participants or other persons or agencies, equipment or other paraphernalia to be involved or used in such temporary use.

Evidence that the Borough will be held harmless from any unforeseen adverse consequences resulting from such temporary use and evidence of the availability of sufficient insurance coverage.

An evaluation of the traffic impact of said use based on the requirements of § 170-85.

The length of time for which a temporary use permit is requested.

Any special requirements, hardships or conditions to be imposed on the Borough or its residents or to other uses which may be affected by the temporary use.

Operations subject to state regulation.

Other excavations.
