The purpose of good site design is to create
a functional and attractive development, to minimize adverse impacts,
and to ensure a project will be an asset to a community. To promote
this purpose, a site plan shall conform to the following standards
which are designed to result in a well-planned community without adding
unnecessarily to development costs.
The intent of this section is to promote the
public's health, safety, and general welfare by minimizing noise,
air, and visual pollution; improving the appearance of off-street
parking and other vehicular use areas; requiring buffering between
incompatible land uses; regulating the appearance of property abutting
public rights-of-way; protecting and preserving the appearance, character
and value of the community and its residential neighborhood areas;
preventing soil erosion and soil depletion; and promoting groundwater
retention.
A. Application. These requirements shall apply to all uses, for which site plan review is required. No site plan shall be approved unless said site plan shall show landscaping, greenbelt buffers and screening consistent with the requirements set forth herein. Screening is the enclosure of an area by a visual barrier, which may include a landscape buffer, solid fencing or other materials as specified in Subsections
C,
D,
E and
H of this section.
B. Landscaping plan required. A separate detailed landscaping
plan shall be required to be submitted as part of a site plan review.
The landscaping plan shall include but not necessarily be limited
to the following items:
(1) Location, spacing, size, and root type [bare root
(BR) or balled and burlapped (BB)] and descriptions for each plant
type proposed for use within the required landscape area.
(2) Minimum scale: 1 inch = 100 feet.
(3) Existing and proposed contours on-site and 150 feet
beyond the site at intervals not to exceed two feet.
(4) Typical straight cross section including slope, height,
and width of berms and type of ground cover or height and type of
construction of wall or fence, including footings.
(5) Significant construction details to resolve specific
site conditions, such as tree wells to preserve existing trees or
culverts to maintain natural drainage patterns.
(6) Planting and staking details in either text or drawing
form to ensure proper installation and establishment of proposed plant
materials.
(7) Identification of existing trees and vegetative cover
to be preserved.
(8) Identification of grass and other ground cover and
method of planting.
(9) Identification of landscape maintenance program, including
statement that all diseased, damaged, or dead materials shall be replaced
in accordance with standards of this chapter.
C. Parking lot landscaping. Separate landscaped areas
shall be required either within or at the perimeter of parking lots.
There shall be one tree for every 10 parking spaces, with a minimum
landscaped space within a designated parking area of 50 square feet.
A minimum distance of three feet shall be established between proposed
tree or shrub plantings and the backside of the curb or edge of the
pavement.
D. Greenbelt buffers. A strip of land with a minimum
width, determined by the front yard setback of its zoning classification,
shall be located between the abutting right-of-way of a public street
or major thoroughfare and shall be landscaped with a minimum of one
tree not less than 12 feet in height or a minimum caliper of two inches
(whichever is greater at the time of planting) for each 30 linear
feet or major portion thereof of frontage abutting said right-of-way.
The remainder of the greenbelt shall be landscaped in berms, ground
cover, shrubs, and/or other natural living, landscape material.
E. Site landscaping.
(1) In addition to any landscape greenbelt and/or parking
lot landscaping required by this section, 10% of the site area, excluding
existing thoroughfare right-of-way, shall be landscaped.
(2) Areas used for storm drainage purposes, such as unfenced
drainage courses or retention areas in front or side yards, may be
included as a portion of the required landscaped area not to exceed
5% of the site area.
F. Landscape elements. The following minimum standards
shall apply:
(1) Quality. Plant material and grasses shall be of generally
acceptable varieties and species, free of insects and diseases, hardy
to Madison County, conform to the current minimum standard of the
American Association of Nurserymen and shall have proof of any required
governmental regulations and/or inspections.
(2) Composition. A mixture of plant material, such as
evergreen, deciduous trees and shrubs, is recommended as a protective
measure against insect and disease infestation. A limited mixture
of hardy species is recommended rather than a large quantity of different
species to produce a more aesthetic, cohesive design and avoid a disorderly
appearing arrangement.
(3) Berms. Berms shall be constructed with slopes not
to exceed a 1:3 gradient with side slopes designed and planted to
prevent erosion, and with a rounded surface a minimum of two feet
in width at the highest point of the berm, extending the length of
the berm. Berm slopes shall be protected with sod, seed, shrubs or
other form of natural ground cover.
(4) Existing trees.
(a)
If existing plant material is labeled "To Remain"
on site plans by the applicant or required by the Joint Zoning Board
of Appeals/Planning Commission, protective techniques, such as but
not limited to fencing or barriers laced at the dripline around the
perimeter of the plant material shall be installed during construction.
No vehicle or other construction equipment shall be parked or stored
within the dripline of any plant material intended to be saved. Other
protective techniques may be used, provided that such techniques are
approved by the Joint Zoning Board of Appeals/Planning Commission.
[Amended 11-8-2017 by L.L. No. 5-2017]
(b)
In the event that healthy trees which are used
to meet the minimum requirements of this chapter or those labeled
to remain are cut down, destroyed, damaged, or excavated at the dripline,
as determined by the Joint Zoning Board of Appeals/Planning Commission,
the contractor shall replace them with trees which meet ordinance
requirements.
[Amended 11-8-2017 by L.L. No. 5-2017]
(c)
Installation, maintenance, and completion. All
landscaping required by this chapter shall be planted prior to obtaining
a certificate of occupancy. A letter of credit and/or certified check
shall be placed in escrow in the amount of the cost of landscaping,
to be released only after landscaping is completed.
G. Installation and maintenance.
(1) All landscaping and landscape elements shall be planted
and earth moving or grading performed, in a sound workmanlike manner
and according to accepted good planting and grading procedures.
(2) The owner of property required to be landscaped by
this chapter shall maintain such landscaping in a reasonably healthy
condition, free from refuse and debris. All unhealthy and dead material
shall be replaced within one year of damage or death or the next appropriate
planting period, whichever comes first. All landscaped areas shall
be provided with a readily available and acceptable water supply.
H. Fencing and screening. Unless otherwise specified
or determined by the Joint Zoning Board of Appeals/Planning Commission,
fencing and screening is to be no greater than six feet in height.
Measurement in excess of six feet in height shall require a variance.
Gateposts and other superstructures over site entrances and exits
may be up to 12 feet in height. Fencing and screening materials of
a height greater than three feet are not to be located within a required
front setback or side setback adjacent to a street.
[Amended 11-8-2017 by L.L. No. 5-2017]
(1) Outdoor storage: to be screened on all sides by a
solid wall or fencing.
(2) Public utility substations: to be screened on all
sides by a solid wall or fencing and landscaping.
