C. 
All plantings shall be installed and maintained for the full length and width required for the Buffer Planting Strip in a particular district. Only the following Structures may be located within the Buffer Area:
(1) 
The required landscape treatment such as Berms, fences, or walls that aid in screening and do not conflict with the character of adjoining properties or block the Sight Distance required at intersections.
(2) 
Appurtenant landscaping Structures, such as tree wells, tree guards and tree grates, and retaining walls used to preserve stands of existing trees or used for other functional purposes.
(3) 
Roads and/or driveways that provide direct ingress/egress for the Lot, including appurtenant Structures within such Road Rights-of-Way such as curbs, sidewalks, and Signs, which shall be landscaped in accordance with the requirements of this chapter.
(4) 
Underground utilities.
(5) 
No Structures other than those set forth in this Subsection C shall be placed within a Buffer Area, and no parking of any kind shall be permitted within the required Buffer Area.
D. 
The intent is to preserve existing trees wherever possible. Areas in which trees are to be preserved shall remain at original grade level and in an undisturbed condition.

§ 135-186 Landscaping requirements.

A. 
All required landscaping shall be installed and maintained in accordance with a Landscape Plan Approved by the Board of Supervisors. A Landscape Plan shall depict all proposed plantings as required within Buffer Areas in the form of a Buffer Planting Strip, and in other Landscaped Areas that relate to, complement, screen or accentuate Buildings, Roads, parking areas, sidewalks, walkways, sitting areas, service or maintenance Structures, courtyards, and other Lot features.
B. 
The Landscape Plan shall be submitted when all other required applications and/or Plans are submitted. It shall be based on and reflect the following:
(1) 
The functional and aesthetic factors that relate to the property, and to the Principal and Accessory Building and other Structures.
(2) 
Concealing views to the property.
(3) 
Enhancing views from and within the property.
(4) 
Screening and complementing proposed Buildings and other Structures.
(5) 
Creating visual interest for the users and/or residents of the proposed project.
(6) 
Using plant materials that are hardy and acclimated to the conditions of the property and within the Township.
C. 
The Landscape Plan shall include notes, diagrams, sketches, or other depictions to present the consideration and analysis of the following:
(1) 
An analysis of the site in terms of the existing views to and from the areas that are proposed for Development, existing topography and Vegetation conditions, and other existing conditions that are relevant to the Lot.
(2) 
An analysis of proposed planting and other landscaping needs as related to screening views of Buildings, storage areas, site utilities, parking areas and other areas where vehicles are parked, and other areas that would appropriately be screened.
(3) 
The consideration of locations where plantings and other landscaping is needed to provide visual interest; define outdoor spaces; complement the proposed architectural style; and achieve other functional and aesthetic requirements for Buffer Areas, Buffer Planting Strips, and other Landscaped Areas.
(4) 
The intent is to preserve existing trees wherever possible. The protection of trees 12 inches or more in DBH (measured at a height 4 1/2 feet above the original grade) shall be demonstrated as a factor for determining the location of Buildings, Open Space, Structures, underground utilities, walks, paved areas and other Structures. Areas in which trees are to be preserved shall remain at original grade level and in an undisturbed condition.
D. 
A preliminary and final Landscape Plan shall reflect the following detailed criteria, unless more specific criteria are provided for in other articles of this chapter:
(1) 
Buffer Planting Strips shall be installed and maintained in the Buffer Areas at the width required in this chapter to form a Continuous Visual Buffer. The Buffer Planting Strip shall be located in the most advantageous position within the Buffer Area in order to provide maximum screening, and provide the most suitable growing conditions for the plants within the Buffer Planting Strip. A preinstallation inspection of the proposed location of the plantings within the Buffer Planting Strip shall be conducted by the Township in order to ensure the most suitable location for the plantings has been selected. In addition to ground covers, and evergreen shrubs at a minimum height of three feet at the time of planting in two alternating rows spaced on ten-foot centers, the Buffer Planting Strip shall include evergreen trees (such as spruce, pine or hemlock) that are a minimum of eight feet in height at the time of planting and shall be spaced in two alternating rows on ten-foot centers. The combined evergreen shrub and tree plantings shall constitute a continuous visual screen at the time of Occupancy of any Buildings, and/or at the time of initiation of any use. In the event such plantings do not provide a Continuous Visual Buffer, the plantings shall be placed upon a Berm at a height from three feet to five feet to enhance their effectiveness.
(2) 
Shade trees shall be provided along all Streets and shall be located at least three feet beyond the Right-of-Way line. No fewer than one three-inch to 3 1/2-inch in Caliper shade tree shall be planted for each 30 feet of roadway length.
(a) 
Such trees shall be planted in alternating rows whereby trees on one side of the Street are placed at intervals of 60 feet. However, such trees may be grouped in certain cases to achieve a particular design objective when Approved by the Board of Supervisors. Further, if there are any existing viable shade trees on either side of the Street that will be retained and protected, the location of these existing shade trees shall inform the placement of new shade trees to be provided along the Street.
(3) 
The outer perimeter of all parking areas shall be screened.
(a) 
Effective screens may be accomplished through the use of plant materials, fencing or walls and/or mounding through the use of earthen Berms.
(4) 
Parking lots shall be landscaped as required in Article XXIV and Article XXV.
(5) 
All Buildings in the B, B-1, POC, BPO, PBC, PBC-1, LI, LI-1, MC, R-MA, CC and PRD districts shall be landscaped in accordance with the following criteria:

(b) 
At least one three-inch to 3 1/2-inch Caliper deciduous tree shall be planted for every fifty-foot length of Building perimeter measured from end to end of Buildings, without regard to indentations and the like in the Buildings, and excluding any enclosed walkway connectors and elevator cores. Such trees shall be planted in close proximity to the Building perimeter, and shall be a minimum of 11 feet to 13 feet in height at the time of planting; and one eight- to ten-foot evergreen tree shall be planted for every 50 feet of length of Building perimeter.
(c) 
Five evergreen and/or deciduous shrubs at a minimum height of 30 inches shall be planted for every 20 feet of length of Building perimeter.
