a.
A landscape plan for the development site shall be submitted b a
New Jersey Certified Landscape Architect to the Planning Board for
approval. The name, address, signature, certification number and seal
of the Certified Landscape Architect shall appear on the plan.
1.
The plan, drawn to scale on a topographic base, shall as a minimum,
include the following:
(a)
Show areas of woodlands. Any tree six-inch caliper or greater within
the limit of disturbance and extending 25 feet beyond the limit of
disturbance shall be shown on the survey. Note on the plan the understory
and overstory species present, range in caliper size, height and health.
(b)
Methods to be used to ensure protection of existing trees, and the
critical root zone of existing trees during construction.
(c)
Number and size of trees requiring removal and specific plans for
replacement.
(d)
Location, number, size, spacing and species of all new plantings.
(e)
Proposed plant material drawn to scale at mature size. The scale
used shall be sufficient to adequately show the overall concept.
2.
The requirements of the landscape plan set forth in paragraph a.1
above shall be appended to the checklist for completeness required
on applications for development and shall be distributed to applicants
together with the application for development.
a.
Every applicant for subdivision or site plan approval shall comply
with the following minimum standards. The Planning Board may require
additional landscaping to create an appropriate landscaping scheme
for the site given the nature of the site and the proposed development
with respect to any issue not addressed by the standards. New Jersey
and Pennsylvania trees are preferred.
1.
General. The overall purpose of site landscaping is to enhance the
natural characteristics of the site, create a sense of place, reduce
nonpoint source pollution runoff and facilitate storm water management.
These goals of site landscaping are accomplished by maintaining and/or
reestablishing the character and tone of the natural vegetation in
the area; lessening the visual impact of buildings, structures and
paved areas; providing for soil stabilization; and providing a diversity
of plant communities, including river corridors, wetlands, upland
fields, meadows and successional woodlands. Landscaping shall be designed
to improve microclimates around buildings.
2.
Character and Tone of Vegetation. Identifying and understanding the
character and tone of vegetation existing and surrounding the site
are paramount to achieving the landscape goals set forth above. The
character and tone of existing vegetation are determined by identifying
the environmental setting, e.g. forest, meadow, floodplain, in which
the site is located and the stage of development of the vegetation,
e.g., successional field, successional woodlands, etc.
An identification of the types of canopy, understory, shrubs
and ground cover further this understanding of the site. The landscape
design shall complement the character and tone of existing vegetation
indigenous to the area. Plantings shall be grouped and multilayered.
Plant species shall be repeated throughout the site to provide continuity
and cohesiveness in the landscape design. Plants' susceptibility
to disease, their colors, textures, shapes, blossoms, and foliage
characteristics shall be considered in the overall design of the landscape
plan.
3.
Soils and Water. Local soil conditions and water availability shall
be considered in the choice of landscaping. Soil preparation prior
to planting or lawn installation shall be completed to minimize the
need for fertilizer and pesticide use. In naturalized and open space
areas the native topsoil shall not be removed.
4.
Plant Size. In the design process, the mature size of the plant shall
be considered for its effect on circulation patterns, solar exposure,
site lighting, drainage, emergency access and relationship to buildings
and streetscape.
5.
Prohibited Vegetation.

them to be immediately pruned up to seven feet height upon planting.
2.
Naturalized Street Tree Planting:
(a)
Vary street tree species, spacing three to 10 feet from the
curb line and within the right-of-way. Provide trees that range in
size from 2 1/2 inches to 3 1/2 inches caliper. Use native
tree species that are indigenous to the area. The total number of
