The purpose of the landscaping requirements in this chapter
is to enhance health safety and quality of life by providing for screening
and buffering; aiding in the reduction of noise, heat, and glare;
minimizing erosion and sedimentation; and a healthier environment.
These requirements are designed to promote sustainable landscapes
within the Township, conserve and restore healthy soils, reduce the
use of irrigation for landscapes, improve the quality of surface waters,
reduce energy consumption, provide wildlife habitat, and protect and
restore native plant communities. They will likewise assist York County
with cleaning up impaired waters in both MS4 and non-MS4 municipalities,
and meeting the countywide target water quality thresholds.
As used in this chapter, the following terms shall have the
meanings indicated:
BUFFER
A landscape area, or an area of preserved vegetation, intended
to be used as a means of limiting the potential adverse effects created
by a use, on adjoining properties or streets.
CRITICAL ROOT ZONE (CRZ)
Portion of the root system that is the minimum necessary
to maintain vitality or stability of the tree. Encroachment or damage
to the critical root zone will put the tree at risk of failure. The
CRZ equals 12 inches of radius from the trunk for each inch of trunk
diameter measured at 4 1/2 feet (4.5) above ground level.
DRIPLINE
An area on the ground defined by the outermost circumference
of tree canopy.
HEDGEROW
A row of dense vegetation in a linear design for the purpose
of wildlife habitat, pollinator food and habitat, windbreak, or to
limit spray drift.
INVASIVE PLANT
A nonnative plant that reproduces more rapidly, out-competes,
and displaces native plants in the landscape. Invasive plants are
listed in the PA DCNR publication "Invasive Plants in Pennsylvania,"
including watch list species, and "Invasive Plants of Pennsylvania
Fact Sheets."

and fences.
B. Existing plants may be used for the screening, as long as the height,
opacity and evergreen requirements are met.
C. Screens shall provide a 100% visual barrier to the element at a height
of four feet at the time of installation. Screens shall provide a
100% visual barrier to the element at a height of six feet within
two years. Landscape plants shall be placed in multiple staggered
rows.
Meadows may be used in place of ground cover (see §
280-8, Plant material) or turf in any area required to be landscaped, according to the following:
A. All plants installed in a meadow shall be native plants. No plants
on the DCNR "Invasive Species List," including Watch List species,
or the PA Department of Agriculture "Noxious Weeds List," shall be
allowed to grow in the meadow.
B. Meadows shall consist of a minimum of three grass species and four
flowering perennial species. Meadows may be installed using seed or
plants.
C. A meadow planting shall have a minimum four-foot-wide mown turf border
along any road or property line. A minimum four-foot-high visual barrier
may be used in place of the turf border between the meadow and a property
line.
D. The mature height of a meadow must meet all requirements for plant
material in a clear sight triangle.
E. Meadows may not be mown more than twice per year; once in March or
April to cut stems that were left standing through the winter, and
once more if needed to control invasive species.
The estimated, or if known, the actual cost of all landscape
materials depicted on the approved landscape plan and installation
costs shall be provided and be financially secured, guaranteed and
maintained consistent with the following subsections. For the purposes
of Section 014 only, the term "landscape plan" shall also apply to the
required landscape vegetation and elements depicted on a subdivision
plan.
A. All landscape improvements to be provided shall be installed and
maintained by accepted practices as recognized by the ANLA. Planting
and maintenance of vegetation shall include, as appropriate, but not
necessarily limited to, provisions for surface mulch, staking and
guying, tree straightening, irrigation, fertilization, insect and
disease control, pruning, mulching, weeding, and watering.
B. The applicant shall make arrangements acceptable to the Township
that all landscape improvements installed in accordance with this
chapter shall be guaranteed and maintained in a healthy and/or sound
condition, or otherwise be replaced by equivalent improvements, for
a period of 18 months following their installation, except as may
otherwise be required by this section.
C. After installation and prior to commencement of the guarantee period
required above, the Township shall perform an inspection of the finished
site for compliance with the approved landscape plan. Following this
inspection, an as-built landscape plan shall be furnished to the Township
by the applicant. Provided the finished site is found to be in compliance,
the first eighteen-month guarantee period shall commence five days
from the date of inspection. All plants shall be in a vigorous and
thriving condition at the end of the eighteen-month period as determined
above. Final inspection of the site following the eighteen-month period
will be made by the Township. It is recommended that trees and shrubs
be planted between September 15 and November 1 or between March 1
and May 1.
D. Plants found to be in poor health during the eighteen-month guarantee period shall be replaced with nursery-grown plants, in accordance with the approved landscape plan, within 30 days of being notified by the Township. If notification is made out of season, replacements shall be made during the next planting season. If the original plants declined due to poor species selection, substitute plants, determined by the Township to be more suitable for the site's environmental conditions or planting scheme, shall be used, and a modified landscape plan shall be filed with the Township. Replacement plants shall be inspected by the Township after installation. All replacement plants shall be subject to a new eighteen-month guarantee period and inspections by the Township as prescribed in Subsections
B and
C above.
E. Where accidental damage or vandalism of plants occurs, the applicant
shall replace the damaged plant material in accordance with the original
or an approved modified landscape plan.
F. The applicant shall be required to post financial security for the
maintenance and/or replacement of the proposed vegetation, including
compensatory plantings, during the eighteen-month guarantee period.
The amount of the financial security shall be equal to 110% of the
amount of the cost estimate submitted with the approved landscape
plan. In addition, financial security shall be required for existing
trees to remain where soil disturbance is within the dripline, if
the trees are counted toward any requirement of the Sustainable Landscaping
Ordinance. Financial security is not required for existing preserved
trees outside the construction limits or for material not being used
to satisfy the minimum requirements of this chapter.
G. The applicant shall make arrangements acceptable to the Township
for the long-term landscape maintenance of common lands and facilities.
The applicant shall provide the names, addresses and telephone numbers
of those persons or organizations who will be assuming such responsibilities.
Landscape improvements required by this chapter shall be the subject
of suitable restrictive covenants and, if practicable, rules and regulations
governing the use and maintenance of common land and facilities, which
covenants, rules and regulations shall be in form and substance acceptable
to the Township Solicitor and, in the case of covenants, recorded
as encumbrances running with the land on which the improvements are
installed. The covenants, rules and regulations shall, without limiting
the forgoing, require the maintenance and replacement, and prohibit
the destruction or removal, of all landscape materials and improvements
depicted on the approved landscape plan, empower the Township to enforce
said obligations, and prohibit the amendment or termination of any
of the mandatory terms thereof without the express joiner of the Township.
Upon presentation of proper credentials, the Township may enter
at reasonable times upon any property within the municipality to inspect
the condition of the landscape in regard to any aspect regulated by
this chapter.
