76-174. Landscaping requirements. |
(a)
General requirements.
(1)
Whenever any front, side or rear yard is not designated for
building, off-street parking, loading and unloading, storage or other
purpose within the terms and requirements of a given zoning district,
the yard shall be landscaped with either approved natural materials
or living plant materials which shall be maintained in an aesthetically
pleasing condition.
(2)
All landscaping shall consist either of approved natural materials
or living plant materials. All landscaped areas shall be protected
from the encroachment of vehicles by curbing or other suitable device,
as approved by the planning commission. The installation of sprinklers
shall be required to ensure the maintenance of all landscaped areas.
(3)
A detailed landscape plan for all yard areas shall be submitted
to the planning commission showing the common and botanical names,
location, spacing, starting size and planting and staking details
of all plantings to be installed, and the location and types of all
natural materials proposed to be included in the landscape treatment
of the yard areas. This provision shall apply to all landscaped yards
including those expanded beyond the minimum setback requirements of
this article. This landscape plan shall be reviewed and approved by
the planning commission.
(4)
Existing significant trees, tree stands, natural vegetation and wildlife habitat shall be integrated into the site landscape plan to the maximum extent possible and shall meet the standards of section 76-173.
(5)
Undeveloped open portions of the site and subsequent phases
of the site shall be seeded, mowed and maintained.
(6)
The planning commission may approve constructed features of
other materials such as masonry walls or brick, stone and cobblestone
pavement as a supplement or substitute, upon a showing by the applicant
that general plantings will not prosper at the intended location.
(7)
Landscaping shall be planted, landscape elements shall be installed,
and earth moving or grading performed in a sound workmanlike manner
and according to accepted good planting and grading procedures, with
the quality of plant materials and grading as described in subsection
(c) of this section. A copy of current acceptable standards is available
from the township building department.
(8)
The owner of property required to be landscaped by this section
shall maintain such landscaping in good condition so as to present
a healthy, neat and orderly appearance, free from refuse and debris.
All plant materials shall be continuously maintained in a sound, weed-free,
healthy and vigorous growing condition and shall be kept free of plant
diseases and insect pests. All unhealthy and dead material shall be
replaced within one year or the next appropriate planting period,
whichever comes first.
(9)
Plant and grass materials shall be of acceptable varieties and
species, free of pests and diseases, hardy in the county, and shall
conform to standards of the American Association of Nurserymen and
the township, and shall have passed any inspections required under
state regulations. Standards shall be in written form and made available
by the building department. No plant materials used to satisfy some
or all planting requirements of this section shall be comprised of
nonliving materials, except as provided here in this section.
(10)
Approved ground cover used in lieu of grass, in whole or in
part, shall be planted in such a manner as to present a finished appearance
and reasonably complete coverage after one complete growing season,
with at least three plants per square foot.
(11)
Grass areas shall be planted in species normally grown as permanent
lawns in the county. Grass may be plugged, sprigged, hydroseeded,
seeded or sodded, except that rolled sod, erosion reducing net or
suitable mulch shall be used in swales or other areas subject to erosion.
Grass, sod and seed shall be clean and free of weeds and noxious pests
or diseases.
(b)
Design objectives. The following general design objectives and criteria
shall be considered in the evaluation of landscape plans:
(1)
Ample variety and quantity of ornamental plants, trees and shrubs
should be provided. A few dominant types are usually chosen with subordinate
types interspersed for accent. Repeating some types creates unity,
but no types should be overused. Variety should be achieved with respect
to seasonal changes, species selected, texture, color and size at
maturity.
(2)
Landscaping should be encouraged that will serve the functions
of enhancing the visual environment, ensuring public safety, moderating
the microclimate and minimizing nuisances.
(3)
Landscaping should serve to integrate the project with the site,
with a particular sensitivity to the natural topography, drainage
and existing native vegetation. It should enhance the architecture
of surrounding structures, when possible, by being of similar scale.
(4)
Preservation of the existing landscape material and landforms is mandatory, particularly where mature trees are a part of the site to the standards of section 76-173.
(5)
Visual variety should be the aim of landscaping treatment. Landscaping
should be used to break up large expanses of pavement.
(6)
Local soil, water, and other climatic conditions should be considered
when choosing landscape materials to create optimum conditions for
their survival and to ensure that they will thrive with a minimum
amount of maintenance.
(7)
Landscaping should be protected from vehicular and pedestrian
encroachment. Raised planting surfaces and the use of curbs are ways
of achieving this objective.
(8)
Species that are a public nuisance or that cause litter should
be avoided. When landscaping is to be installed in areas that children
will frequent, trees and bushes with sharp needles shall be prohibited.
(9)
The aesthetic and functional aspects of the proposed landscaping,
both at installation and at maturity, shall be a paramount consideration
in review and approval by the planning commission.
(c)
Plants and materials.
(1)
All plant materials used shall be placed in fertile soil with
good surface drainage and shall be given reasonable maintenance necessary
to ensure their healthy existence and survival. All natural materials
shall be maintained, refurbished or replaced, as necessary, to ensure
a positive aesthetic quality.
(2)
All proposed landscaped plantings shall meet the minimum size
requirements specified in the following table:
Editor's Note: The table entitled "Plant Material Size" is
included as an attachment to this chapter.
(d)
Prohibited plant materials. Where a landscape plan is required, the
following plant materials are specifically prohibited:
(1)
Boxelder.
(2)
Soft maple (red silver).
(3)
Elm.
(4)
Poplar.
(5)

Horse chestnut (nut bearing).
(7)
Tree of heaven.
