existing tree assessment that identifies the type and size of all
canopy and evergreen trees within the preservation strip.
D. Site perimeter buffer requirements are not superseded by the landscaped
berm setback requirements.
E. Exception. The site perimeter buffer is not required where the development
of two or more adjoining lots are being master planned together and
the property line to be buffered falls within a logical location for
a parking lot, drive aisle, or other paved area.
12. Use Buffer.
A. All development of nonresidential uses that are contiguous, abutting,
or adjacent to any residential zoned property shall maintain a fifty-foot
nondisturbance development buffer from the lot line abutting any residential
zoning district. The fifty-foot development buffer area shall not
be cleared of vegetation or graded, except that vegetation may be
disturbed to the extent that additional landscaping within the nondisturbance
buffer will enhance the buffer area.
B. The buffer area shall provide an adequate buffer to visually screen
the proposed nonresidential use from off-site view. The nonresidential
buffer shall be planted with the following plants for every 100 linear
feet of lot line to be buffered. The plantings shall be planted in
staggered rows to provide an effective visual screen.
C. Existing Vegetation. Where existing stand of trees sufficient to
serve as a visual screen occurs along the required buffer area, a
fifty-foot preservation strip may be substituted, in lieu of the nonresidential
buffer.
(1)
Development activity shall not disrupt the root network of existing
vegetation within any preservation strip. The root zone of vegetation
located in a preservation strip shall be shown on the landscape plan
and correspond with the limits of disturbance.
(2)
The applicants seeking a fifty-foot preservation substitute
shall provide an existing tree assessment that identifies the type
and size of all canopy and evergreen trees within the existing stand
of trees.
D. The use buffer, when required, supersedes the site perimeter buffer
requirements.
E. The use buffer is not superseded by the landscaped berm setback requirements.
13. Nonresidential Landscaped Berm.
A. Where parking, interior drive aisles, loading areas, building service
entrances, trash enclosures, or loading docks in a nonresidential
zoning district adjoin residential zoning districts, they shall provide
a landscaped berm along the lot line adjoining the residential zoning
district.
B. Berm. The required earth berm shall be a minimum of five feet higher
than the finished elevation of the area to be screened. The berm must
have a crown width of at least three feet and may not have a slope
steeper than a 3:1 ratio.
C. Landscaping. The landscaped berm shall provide an effective planting
screen with a staggered row of trees planted 15 feet on center.
(1)
The landscape berm shall have an equal mix of deciduous and
evergreen trees.
D. Sliding Scale Options for a Required Landscaped Berm.
(1)
The sliding scale options, illustrated in Attachment 9, Drawing
Z-4, may be used only in the Convenience Commercial (C-1) and
Highway Commercial (C-2) zoning districts.
(2)
Use of a sliding scale option where the nonresidential development
is a conditional use shall be permitted only upon a showing of how
the proposed use will impact the adjacent site and how that impact
will be mitigated through the implementation of a sliding scale option.
(a)
Use of the sliding scale will be approved only upon showing
that the proposed buffer is a more efficient, attractive, and harmonious
design solution.
14. Landscape Island Maintenance.
A. A landscape maintenance agreement shall be in place for island areas
in Township or PennDOT rights-of-way if requested by the Township.
