Any part of the site which is not used for buildings, other
structures, loading or parking spaces and aisles, sidewalks and designated
storage areas shall be planted with an all-season ground cover approved
by the Board of Supervisors (e.g., grass, ivy, vetch, pachysandra,
etc.). It shall be maintained to provide an attractive appearance,
and all nonsurviving plants shall be replaced promptly.
[Amended 6-14-1990 by Ord. No. 90-06]
In all cases where screening is required by this chapter, design
standards shall be as follows:
A. An earthen berm two to four feet in height planted with a combination
of evergreen and deciduous trees and shrubs, so as to provide a minimum
opacity of 60% in winter and 80% in summer (between ground level and
six feet above the finished ground level) within two years of installation
shall be provided.
B. The Board of Supervisors may grant substitution to this requirement
when the applicant can prove that the general public interest and
adjoining properties would better be served by one of the following
substitutions: evergreens (trees, hedges, shrubs) planted at existing
grade level, fences or a combination of the above materials.
C. One substitution that is acceptable, if approved by the Board of
Supervisors, is composed of evergreen shrubs and/or trees arranged
in two staggered rows within a twenty-foot-wide strip. The height
of the plant material shall be a minimum of six feet, and it shall
be spaced at intervals of not more than 10 feet on center.
D. All screens shall be permanently maintained to assure the minimum
opacity requirements.
Any use requiring an off-street parking lot containing more
than 100 parking spaces shall require the preparation of an overall
landscape plan. Such plan shall be subject to review by the Township
Board of Supervisors or its designee.
