B. 
Handicapped Parking. Handicapped parking spaces shall be provided in accordance with the requirements of the Americans with Disabilities Act (ADA) and the Pennsylvania Department of Labor and Industry.
C. 
Parking Area Traffic Control. All parking areas which are laid out in more than two rows of parking stalls shall have traffic control structures for the safe and efficient flow of internal vehicular and pedestrian traffic. Such structures shall consist of concrete curbs, sidewalks or parking aisle separators, extending not less than six inches above the finished surface of the lot, or planted and landscaped areas, or other equivalent devices as may be approved by the Planning Commission. Any such planted area shall be protected by poured concrete curbing to prevent vehicle encroachment thereon.
D. 
Access. Access to parking areas shall be provided in accordance with the following requirements:
(1) 
Where an existing lot does not adjoin a public or private street, alley or easement of access, an access drive shall be provided leading to the parking area.
(2) 
Access to off-street parking areas shall be limited to defined driveway locations, and in no case shall there be unrestricted access along the length of a street. In any Zoning District, other than a Residential District, the street frontage shall be curbed to restrict access to the lot, except where access drives are proposed.
(3) 
The number of access drives from a single lot or development to any public street shall not exceed two for every 400 feet of street frontage.
(4) 
Access drives entering State highways are subject to a highway occupancy permit issued by the Pennsylvania Department of Transportation (PennDOT).

Access to Borough streets shall be graded to conform to existing topography and shall be designed so that drainage will not adversely impact the street or adjacent properties.
(5) 
Each parking space shall have access directly to an aisle. Interior circulation of traffic shall be designed so that no aisle providing access to parking spaces shall be used as a through street. Interior traffic circulation shall be designed to ensure safety and access by emergency vehicles.
E. 
Safety Requirements. Borough Council upon recommendation of the Planning Commission and Borough Engineer, shall consider whether safety requirements are warranted to reduce traffic hazards which endanger public safety. The developer shall be responsible for construction of any required islands, acceleration, deceleration or turning lanes and shall bear the cost of installing any required traffic control devices, signs or pavement markings on public streets within and adjacent to the boundaries of the development site.
F. 
Marking. In parking areas which contain five or more spaces, all parking spaces shall be clearly delineated by painted lines or markers. Parking spaces shall be provided with bumper guards or wheel stops, where necessary, for safety or protection to adjacent structures, walkways, roadways or landscaped areas. All vehicular entrances and exits to parking areas shall be clearly marked for all conditions. Short-term visitor parking spaces shall be differentiated from long-term employee parking spaces by suitable markings. Handicapped parking shall be appropriately marked.
G. 
Shared Garages. Shared garages in joint ownership, having party walls along common property lines, shall be permitted provided each space is separately owned or an easement or other agreement for a shared driveway is recorded with the deed.
H. 
Parking Areas Containing Five or More Spaces.
(1) 
Parking areas containing five or more spaces shall be paved, striped and curbed and shall be designed in accordance with the requirements of this chapter. In parking areas containing more than five spaces, all driveways and parking spaces shall be paved with an eight-inch base and an asphalt or concrete top of two-inch minimum, or a design of higher strength and shall be graded with positive drainage to dispose of surface water in a manner that shall not affect adjacent properties.
(2) 
Where five or more parking spaces are required by this chapter, the parking spaces shall be located on the same lot with the principal use, unless approved by Borough Council upon recommendation of the Planning Commission, provided the off-site parking area is located within 300 feet of the structure or building which it is intended to serve.
(3) 
No parking area containing more than five parking spaces shall be located closer than 10 feet to any adjacent property line. Parking areas containing five or more spaces shall not be permitted in the required front yard in any "S" Conservancy or "R" Residential Zoning District. Parking shall be permitted in the required front yard in any "I" Zoning District provided the parking shall be located at least five feet from the public street right-of-way line.
I. 
Screening and Landscaping.
(1) 
Parking areas containing more than five parking spaces shall be effectively screened by a compact evergreen hedge at least six feet in height along any property line which adjoins any dwelling in an S, R-1 or R-H Zoning District.
(2) 
In addition, a planting strip at least five feet wide shall be provided between the edge of the right-of-way and any parking area authorized in any yard which fronts on a street. Planting strips between the right-of-way and the parking area shall be suitably landscaped and maintained in grass, ground cover or other landscaping material not in excess of three feet in height which shall not obstruct visibility for traffic entering or leaving the lot or traveling on the public street.
(3) 
In parking areas containing more than 20 spaces, at least 5% of the interior parking area shall be landscaped with plantings and one tree for each 10 parking spaces shall be installed.
J. 
Lighting. Lighting of parking areas shall be permitted only if the parking area contains five or more spaces. Any lighting used to illuminate off-street parking areas shall be designed to reflect the light away from the adjacent premises and away from any streets or highways. Spillover lighting on adjacent residential properties shall not exceed 0.2 footcandle. The lighting system shall furnish an average minimum of 1.0 footcandle distributed throughout the site during hours of operation and shall be designed with shields and cutoff luminaries that have a cutoff angle of 60° or less.
