[Ord. 1998-5, 7/20/1998, § 6.300; as amended by Ord. 2000-9, 6/19/2000, § 4; by Ord. 2002-7, 9/16/2002, §§ 4, 5; by Ord. 2006-8, 8/29/2006, § 3; by Ord. 2003-3, 5/5/2003, § 6; and by Ord. 2009-2, 3/3/2009, §§ 2-4]
1. Landscaping Requirements, Front Yards. Landscaping along the frontage of every tract, except for area devoted to accessways shall be provided. The landscaped area shall extend toward the interior of the lot for a minimum distance of 25 feet from the proposed right-of-way line or for 1/2 the distance of the front yard setback as per this chapter. In addition to what may be required by §
27-602, low shrubbery, other landscaping, and street trees shall also be required. Street trees shall be planted at a minimum equivalent of 20 feet on-center, with a minimum diameter of 3 1/2 inches at time of planting. Additionally, landscaping between the proposed right-of-way line and the curbline or edge of roadway shoulder shall be encouraged, recognizing that such landscaping may need to be removed in the future for roadway improvements; landscaping in this area, therefore, is encouraged to represent a low financial investment and/or be capable of relocation. In all instances, landscaping shall be so installed to preserve a clear and unobstructed view of oncoming traffic.
2. Landscaping Requirements, Side and Rear Yards. A vegetative ground cover shall be required on at least 50% of all side and rear yards in order to facilitate groundwater absorption and to reduce the adverse effects of soil erosion and stream sedimentation. Buffer yards shall be 100% landscaped with a combination of ground cover, trees and shrubs according to an approved landscape plan.
3. Landscaping Requirements for Off-Street Parking Areas. Requirements are as follows:
A. Interior Parking Lot Requirements for Lots with More than 20 Parking Spaces. For purposes of traffic channelization, definition of parking areas, reduction of visual monotony, and the provision of amenities, an area equivalent, at minimum, to 10% of all surface parking areas shall be devoted to interior parking lot vegetative cover. Such areas shall be in addition to any other landscaping or buffering requirements of this chapter. The location of the vegetative cover may be concentrated or clustered, however, to meet other specified open space and pedestrian needs such as a sitting area.
B. Screening Requirements for All Off-Street Parking Areas. Off-street parking areas and parking structures shall be screened as follows:
(1) Parking lot screening must be provided within 10 feet of the perimeter of the parking lot to be screened or at a distance greater than 10 feet of the perimeter of the parking lot if requested by the applicant and approved by the Board of Supervisors.
(2) Parking lot screening must consist of a single compact hedge row of evergreen and/or densely twigged deciduous shrubs spaced to ensure closure into a solid hedge at maturity. Said hedge must be a minimum of three feet and maximum of four feet in height as measured from the adjacent finished surface of the parking area. It shall be the responsibility of the property owner to maintain said hedge so that it does not exceed four feet in height, and one or more of the following if requested by the applicant and approved by the Board of Supervisors:
(b) An opaque wall or fence of architecturally suitable style and finish satisfactory to the Board of Supervisors.
(3) Parking lot screening shall be in addition to a minimum five-foot wide landscaped buffer strip pursuant to footnote (e).2 of Schedule 27-II and/or a minimum twenty-five-foot-wide buffer strip pursuant to footnote (e).1 of Schedule 27-II, unless otherwise approved at the discretion of the Board of Supervisors.
(4) Off-street parking area or structure screening requirements under this section may be waived, reduced or modified at the discretion of the Board of Supervisors in circumstances where other screening is provided, such as under footnote (e) of Schedule 27-II, where screening may be problematic for property maintenance, such as snow storage, or where the elevation of the parking area relative to the elevation of the street or adjacent property would make the screening ineffectual as determined by the Township Engineer. The applicant, developer or property owner shall provide plans and other data required by the Township Engineer to make such determination.
C. Raised Islands Shall Be Required for Traffic Channelization. To further assist in traffic channelization, raised islands shall be placed at the ends of parking bays, such that the end of the bay adjacent to a driving aisle or ring road is clearly delineated. The island surface, preferably covered with vegetative material, designed so as not to impair traffic access visibility.
4. Revegetation. Revegetation shall be required as part of mine reclamation and may be required by the Supervisors as part of the site alteration as follows:
A. Revegetation, if required, shall provide for a diverse, effective and permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession at least equal in extent of cover to the natural vegetation of the area. Introduced species may be used in the revegetation process where desirable and necessary to achieve the approved post-mining land use plan. Vegetative cover shall be considered of the same seasonal variety when it consists of a mixture of species of equal or superior utility for the approved post-mining site alteration and/or logging land use, when compared with the utility of naturally-occurring vegetation during each season of the year.
B. Revegetation when required shall provide a quick germinating fast-growing vegetative cover capable of stabilizing the soil surface from erosion.
C. Revegetation shall be completed in compliance with the landscape plan submitted for the proposed mining, site alteration, logging and/or other use.
5. Landscape Plan. A landscape plan, prepared by a registered landscape architect or a landscape professional, shall be required, showing all pertinent information for buffer areas, frontage landscaping, interior parking lot landscaping and other landscaping required pursuant to this chapter. Pertinent information includes all individual trees and shrubs to be planted or to be preserved.
6. Landscape Maintenance.
A. Material Maintenance. The property owner must maintain all landscaping and screening materials required by this chapter or shown on the approved landscape plan. Required or approved landscaping materials that are dying, dead, diseased or removed for any reason within one year of initial planting shall be replaced within three months or at the beginning of the next planting season if frost conditions are evident within three months. Such requirement shall become part of the terms of any development agreement as provided for in the Subdivision and Land Development Ordinance [Chapter
22].
B. Structure Maintenance. Landscaping and screening structures such as fences and walls must be maintained in good condition, free of graffiti, peeling paint, decay or warping; must be repaired if damaged and replaced periodically to maintain a structurally sound condition.
C. Surety. To ensure that landscaping is installed as proposed and survives for one year from the time of planting, a landscape performance surety must be submitted to the Township prior to issuance of a zoning occupancy permit for any project where landscaping is required. The landscape surety amount shall be set by the Board of Supervisors. The surety shall consist of a bond, an irrevocable letter of credit, cash deposit or other instrument approved by the Township Solicitor which provides an adequate performance guarantee to the Township.
7. Landscaping of Communications Service Facility. Landscaping shall be required for any new communications tower and/or communications equipment building as follows:
A. Communications towers shall be landscaped with evergreen trees suitable to provide an immediate visual screening at least six feet in height. In addition, tree species and placement shall be such that long term screening of the tower at heights in excess of 30 feet can be expected. In most cases this will require a mixture of columnar and cone-shaped species planted no more than 20 feet on-center in staggered rows.
B. Communications equipment buildings shall be landscaped with a mixture of evergreen trees to screen the building from adjacent properties and/or streets and shade trees, shrubs, and ground cover to restore any cleared area between the building and adjacent properties or streets to a natural condition.
C. The Board of Supervisors may offer relief from the above requirements if the Township Engineer makes a recommendation that existing vegetation will meet the intent of this section throughout the year.
8. Foundation Landscaping. Foundation plantings shall be provided along the front or sides of any nonresidential buildings which face a public road, is adjacent to a parking lot or other area which provides access to the building(s) by the general public. Foundation planting areas shall be integrated into the sidewalk system, where provided (between the front or sides of the building and the parking area and/or associated driveways) adjacent to the building. Foundation planting areas shall contain at a minimum, five shrubs per 35 lineal feet of applicable building frontage. The minimum width of the landscape strip shall be four feet as measured from the foundation.
9. Landscaping and Screening Limitations.
A. Plant and screening materials shall not obstruct clear site distance or triangles.
B. Any tree, plant, shrub, flower, vine or grass species which has been classified as invasive, noxious or destructive by any local, county, state or federal agency shall be specifically prohibited for use in landscaping and ground cover.
