F. 
Pedestrian walkways. Where parking spaces on a property are located in excess of 140 feet from the building they are designed to serve, a pedestrian walkway shall be provided in the parking area not less than four feet in width connecting the parking spaces to the entrances to the building. Such pedestrian walkways may occur between rows of parking spaces where the spaces are at right angles to the building or along the ends of rows where the spaces are arranged parallel to the building. A walkway along the edge of the parking area adjacent to the building, raised six inches above the parking area, shall be provided, connecting to the building entrances. A handicapped ramp or ramps shall be constructed between the parking area and raised walkway adjacent to the building.

Such lighting may be from freestanding lampposts within the parking areas, from nearby street lights or from lights mounted on buildings.
(2) 
Lighting shall be shielded or aimed so as not to create glare conditions on adjacent streets or properties. The provisions of Article VI, Generally Applicable Provisions, § 300-28, Performance standards, Subsection G, Glare, of Chapter 300, Zoning, shall be applicable to all exterior lighting.
(3) 
Light standards in parking areas shall be protected from accidental damage by vehicles through the installation of concrete-filled bollards, raised islands or planted areas.

Landscaping.
(1) 
All areas of the property not paved or occupied by buildings shall be landscaped and maintained. At least 5% of the area of the property lying between the abutting street and the principal building or buildings on the property shall be set aside for landscaping. Where the property abuts two streets, at least 8% of the area between the streets and principal building or buildings shall be set aside for landscaping. Lot areas not covered by buildings, sidewalks, pavement or other improvements shall be seeded with grass or other appropriate ground cover material compatible with the landscape and architectural design and condition of the surrounding areas.
(2) 
Landscaping may take the form of grassed areas, shrubbery, trees, ground cover, mulching materials, boulders or other features in combination and shall conform to accepted minimum standards. Landscaping materials shall not obstruct sight distances at access points to the property. Existing vegetation shall be considered as meeting the minimum standards for planted materials in this subsection when identified on the site plan.
[Amended 12-21-2009 by Ord. No. 846]

Where properties abut residentially zoned lots, the following requirements shall apply:
(a) 
All sites in a "C" classified zone having a common boundary with an "R" classified property shall erect and maintain a view-obscuring fence or dense coniferous hedge to a height of not less than six feet along such common boundary for purpose of controlling access and providing visual and noise buffers between the dissimilar uses.
(b) 
All sites in an "M" classified zone having a common boundary with an "R" classified property shall have planted and maintained along such common boundary a view-obscuring coniferous greenbelt of shrubs, trees and native vegetation not less than eight feet in height nor less than 10 feet in width, for screening purposes and controlling access.
(c) 
In any zoning district, sites approved for development of nonresidential uses, whether permitted as uses by right, conditional uses or special exceptions, and which share common boundaries with residentially zoned lots, shall be required to erect and maintain a view-obscuring fence or dense coniferous hedge to a height of not less than six feet along such common boundary for purposes of controlling access and providing visual and noise buffers between the dissimilar uses.
(4) 
Where plantings are used as a screen, they shall be not less than three feet in height above ground level when planted and arranged to create a dense hedge when mature. The Board of Commissioners may modify these requirements where topography or existing natural growth to remain on the property after development will serve the purpose of a screen.
(5) 
The developer shall post a performance bond and a maintenance bond or other security satisfactory to the Township Solicitor in an amount approved by the Township Engineer, equal to the estimated cost of the landscaping to guarantee implementation of the landscaping bond to be held for two complete growing seasons to assure stabilization and growth of the landscaping materials.
J. 
Garbage and trash containers. All organic rubbish and discarded materials shall be placed in tight vermin-proof containers on the property and shall be secured in side or rear yards screened from public view by means of a solid-face fence or wall.

Where several commercial or industrial buildings occupy the same property or several commercial or industrial enterprises occupy the same building, there shall be an architectural continuity in the design of the facades of the building or buildings facing the street or streets to which the property has access. Evidence of continuity may be shown by the use of a common wall finishing material, common size, height and lettering style of signs, and similar window and door sizes, heights and arrangements. Unpainted concrete block walls will be permitted only where they are hidden from public view and from the view from nearby residential properties.
L. 
Use of trailers on a commercial or industrial property. No vehicle towed to a site or driven there shall be used for purposes of storage or materials or goods, for temporary expansion of a business or for sales or display of goods.
