This article specifies the landscape and screening requirement,
including techniques for installation and maintenance. Specifically,
this article will:
A. Promote public health, safety, and general welfare by reducing noise,
air and visual pollution, air temperature, and light glare.
B. Align with the community sustainability plan goals, including increasing
the City's tree canopy coverage, reducing the urban heat island effect,
increasing the use of green stormwater infrastructure, and achieving
biodiversity goals.
C. Support the natural features protection goals in the current Master Plan and align with §
50-6.2, including the use of plant species native to southern Michigan.
D. Improve the appearance and environmental impact of paved spaces,
such as parking lots.
F. Align with the Street Design Manual and Chapter
42, Tree Ordinance, to create a comfortable and safe pedestrian network and increase the tree canopy.
The following general provisions for landscaping and screening
apply.
A. Landscape plan. A landscape plan, detailing the required landscaping
and how it will be maintained, including watering during initial installation
and long-term care, will be required with site plan review.
(1) Delay of installation. The City Planner or their designee may authorize
a delay in installation of trees and vegetation due to adverse weather
until no later than the following June 30.
(a)
A bond or letter of credit or other guarantee of such installation
may be required.
(b)
A temporary certificate of occupancy may be issued by the Building
Official or their designee until the landscaping is complete.
B. Plant materials. The following shall be considered when selecting
plant materials:
(1) Maximum percentage of a single species. Except for plantings used
for screening, no one species of tree or shrub may make up more than
33% of the total amount of landscape plantings.
(2) Plant materials. The use of vegetation native to southern Michigan
and the use of a mixture of vegetation from the same species association
is encouraged, and the following shall apply:
(a)
All required plant material shall be hardy to the area, free
of disease and insect infestation, and conform to the American Standard
for Nursery Stock of the American Association of Nurserymen.
(b)
A minimum of 50% of plant material used to meet the landscape
and screening requirements of this article shall be natives or nativars.
(3) Prohibited plant materials. Plantings listed in Table 6.2-6, Prohibited
Plant List, are not to be utilized in any landscape or screening area
required by this article.
(4) Plant material spacing. Plant materials shall be spaced to support
plant health. Specifically, the following applies:
(a)
Plants shall be spaced not less than 75% of their mature size.
(b)
Naturalized planting layouts are permitted and when used are the exception to §
50-8.3B(4)(a).
(c)
Refer to Chapter
42, Tree Ordinance, for spacing of right-of-way plantings.
C. Planting locations. Trees and vegetation shall be installed considering
the following on both private and public property:
(1) Sight visibility. In order to support sight visibility for motorists
and clearance for pedestrians, cyclists, and vehicles, plantings within
the clear view zone may not be taller than three feet at maturity.
Refer to Figure 8.3-1 Clear View Zone.
Figure 8.3-1 Clear View Zone.

(2) Around hydrants. Landscaping planted within a ten-foot radius around
a fire hydrant shall be no taller than six inches at maturity.
(3) Proximity to property line. Trees and large shrubs shall not be placed closer than three feet from the fence line or property line unless otherwise noted in §
50-8.4, Required landscaping. In no case shall trees and shrubs impede access on an adjacent sidewalk.
(4) Right-of-way landscaping. All planting and removal of trees in the City's right-of-way shall be in accordance with Chapter
42, Tree Ordinance, and may require approval of the City's Tree Committee.
E. Protection of trees during construction. The following shall be considered
during construction:
(1) Construction fencing. The critical root zone (CRZ) of protected trees shall be protected following the standards of §
50-6.2J(8), Protection during construction.
(2) Preservation of existing trees during construction. The preservation
of quality, mature trees can earn credits toward the required landscaping
requirements for a site. Refer to Table 8.3-4, Tree Preservation Credits.
