00 - LANDSCAPING, SCREENING AND WALLS
A.
Intent. Landscaping enhances the visual image of the township, preserving natural features, improving property values, and alleviating the impact of noise, traffic, and visual distraction associated with certain uses. Screening is important to protect less intensive uses from the noise, light, traffic, litter and other impacts of more intensive, nonresidential uses. Accordingly, these provisions are intended to set minimum standards for the design and use of landscaping, greenbelts, and screening, and for the protection and enhancement of the township's environment. More specifically, the intent of these provisions is to:
1.
Improve the appearance of off-street parking areas, vehicular use areas, and property abutting public rights-of-way;
2.
Protect and preserve the appearance, character, and value of the neighborhoods which abut nonresidential areas, parking areas, and other intensive use areas, thereby protecting the public health, safety and welfare;
3.
Reduce soil erosion and depletion; and
4.
Increase soil water retention, thereby helping to prevent flooding.
B.
Scope of application. No site plan shall be approved unless it shows landscaping consistent with the requirements of this article. A building permit shall not be issued until the required landscape plan is submitted and approved, and a certificate of occupancy shall not be issued unless provisions set forth in this section have been met or a performance guarantee has been posted in accordance with the provisions set forth in article 17.00.
C.
Minimum requirements. The requirements in this article are minimum requirements, and under no circumstances shall they preclude the developer and the township from agreeing to more extensive landscaping.
D.
Design Creativity. Creativity in landscape design is encouraged. Accordingly, required trees and shrubs may be planted at uniform intervals, at random, or in groupings, depending on the designer's desired visual effect and, equally important, the intent of the township to coordinate landscaping on adjoining properties.
E.
Summary of regulations. The following table summarizes the landscaping regulations contained in this article:
SUMMARY OF MINIMUM LANDSCAPING REQUIREMENTS [1]

In consideration of the overall design and impact of a specific landscape plan, and in consideration of the amount of existing plant material to be retained on the site, the planning commission may modify the specific requirements outlined herein; provided that any such adjustment is in keeping with the intent of this article and Ordinance in general. In determining whether a modification is appropriate, the planning commission shall consider whether the following conditions exist:
A.
Topographic features or other unique features of the site create conditions such that strict application of the landscape regulations would result in a less effective screen than an alternative landscape design.
B.
Parking, vehicular circulation, or land use are such that required landscaping would not enhance the site or result in the desired screening effect.
C.
The public benefit intended by the landscape regulations could be better-achieved with a plan that varies from the strict requirements of this Ordinance.
A.
Obscuring wall standards. Where permitted or required by this Ordinance, obscuring walls shall be subject to the following requirements:
1.
Location. Required obscuring walls shall be placed inside and adjacent to the lot line except in the following instances:
a.
Where underground utilities interfere with placement of the wall at the property line, the wall shall be placed on the utility easement line located nearest the property line.
b.
Subject to planning commission approval, required walls in a nonresidential district may be located on the side of an alley right-of-way closest to the adjacent residential zone when mutually agreed upon by affected property owners and residents. The continuity of the required wall shall be considered by the planning commission in reviewing such requests.
2.
Time of construction. Wherever construction of an obscuring wall is required adjacent to residentially zoned or used property, the wall shall be installed prior to the beginning of site grading and general construction, except where such activity would result in damage to the wall.
3.
Corner clearance. Obscuring walls shall comply with the specifications for maintenance of unobstructed sight distance for drivers, section 12.09.
4.
Substitution or waiver.
a.
As a substitute for a required obscuring wall, the planning commission may, in its review of the site plan, approve the use of other existing or proposed living or manmade landscape features (such as closely spaced evergreens) that would produce substantially the same results in terms of screening, durability, and permanence. Any such substitute screening shall comply with the applicable requirements in section 15.02.
b.
If a fence is approved by the planning commission as a suitable substitute for a required obscuring wall, the fence shall be constructed of redwood, cedar, or No. 1 pressure-treated wood. Chain link fences shall not be permitted for screening purposes.
c.
The planning commission may waive the requirements for an obscuring wall upon making the determination that:
(1)
The adjoining residential district is in transition and will become nonresidential in the future.
(2)
Existing physical features provide adequate screening.
5.
Wall specifications. Required walls shall be constructed of masonry material that is architecturally compatible with the materials used on the facade of the principal structure on the site, such as face brick, decorative block, or poured concrete with simulated brick or stone patterns.
6.
Height requirements. For the uses and districts listed below, an obscuring wall shall be provided as specified along property lines that abut a residential district:
A.
General standards. Walls shall be permitted in residential districts, subject to the standards for location and height set forth in section 12.16.

1.
Entranceway structures shall be located on private property outside of the road right-of-way, except that such structures may be located in the median of a boulevard entrance to a subdivision or other residential development (in the road right-of-way), subject to approval by the Road Commission for Oakland County and subject to compliance with the unobstructed sight distance standards in section 12.08, subsection A.4. Entranceway structures located on private property may be within the required front setback area.
2.
Entranceway structures shall not exceed five feet in height and 60 square feet in size.
3.
Approval of the building official and issuance of a building permit shall be required prior to construction.
00 - LANDSCAPING, SCREENING AND WALLS
A.
Intent. Landscaping enhances the visual image of the township, preserving natural features, improving property values, and alleviating the impact of noise, traffic, and visual distraction associated with certain uses. Screening is important to protect less intensive uses from the noise, light, traffic, litter and other impacts of more intensive, nonresidential uses. Accordingly, these provisions are intended to set minimum standards for the design and use of landscaping, greenbelts, and screening, and for the protection and enhancement of the township's environment. More specifically, the intent of these provisions is to:
1.
Improve the appearance of off-street parking areas, vehicular use areas, and property abutting public rights-of-way;
2.
Protect and preserve the appearance, character, and value of the neighborhoods which abut nonresidential areas, parking areas, and other intensive use areas, thereby protecting the public health, safety and welfare;
3.
Reduce soil erosion and depletion; and
4.
Increase soil water retention, thereby helping to prevent flooding.
B.
Scope of application. No site plan shall be approved unless it shows landscaping consistent with the requirements of this article. A building permit shall not be issued until the required landscape plan is submitted and approved, and a certificate of occupancy shall not be issued unless provisions set forth in this section have been met or a performance guarantee has been posted in accordance with the provisions set forth in article 17.00.
C.
Minimum requirements. The requirements in this article are minimum requirements, and under no circumstances shall they preclude the developer and the township from agreeing to more extensive landscaping.
D.
Design Creativity. Creativity in landscape design is encouraged. Accordingly, required trees and shrubs may be planted at uniform intervals, at random, or in groupings, depending on the designer's desired visual effect and, equally important, the intent of the township to coordinate landscaping on adjoining properties.
E.

The following regulations shall apply to existing plant material:
A.
Consideration of existing elements in the landscape design.
1.
In instances where healthy plant material exists on a site prior to its development, the planning commission may permit substitution of such plant material in place of the requirements set forth previously in this section, provided such substitution is in keeping with the spirit and intent of this article and this Ordinance in general.
2.
Existing hedges, berms, walls, or other landscape elements may be used to satisfy the requirements set forth previously, provided that such existing elements are in conformance with the requirements of this section.
B.
Preservation of existing plant material.

In consideration of the overall design and impact of a specific landscape plan, and in consideration of the amount of existing plant material to be retained on the site, the planning commission may modify the specific requirements outlined herein; provided that any such adjustment is in keeping with the intent of this article and Ordinance in general. In determining whether a modification is appropriate, the planning commission shall consider whether the following conditions exist:
A.
Topographic features or other unique features of the site create conditions such that strict application of the landscape regulations would result in a less effective screen than an alternative landscape design.
B.
Parking, vehicular circulation, or land use are such that required landscaping would not enhance the site or result in the desired screening effect.
C.
The public benefit intended by the landscape regulations could be better-achieved with a plan that varies from the strict requirements of this Ordinance.
A.
Obscuring wall standards. Where permitted or required by this Ordinance, obscuring walls shall be subject to the following requirements:
1.
Location. Required obscuring walls shall be placed inside and adjacent to the lot line except in the following instances:

b.
Subject to planning commission approval, required walls in a nonresidential district may be located on the side of an alley right-of-way closest to the adjacent residential zone when mutually agreed upon by affected property owners and residents. The continuity of the required wall shall be considered by the planning commission in reviewing such requests.
2.
Time of construction. Wherever construction of an obscuring wall is required adjacent to residentially zoned or used property, the wall shall be installed prior to the beginning of site grading and general construction, except where such activity would result in damage to the wall.
3.
Corner clearance. Obscuring walls shall comply with the specifications for maintenance of unobstructed sight distance for drivers, section 12.09.
4.
Substitution or waiver.
a.
As a substitute for a required obscuring wall, the planning commission may, in its review of the site plan, approve the use of other existing or proposed living or manmade landscape features (such as closely spaced evergreens) that would produce substantially the same results in terms of screening, durability, and permanence. Any such substitute screening shall comply with the applicable requirements in section 15.02.
b.
If a fence is approved by the planning commission as a suitable substitute for a required obscuring wall, the fence shall be constructed of redwood, cedar, or No. 1 pressure-treated wood. Chain link fences shall not be permitted for screening purposes.
c.
The planning commission may waive the requirements for an obscuring wall upon making the determination that:
(1)
The adjoining residential district is in transition and will become nonresidential in the future.
(2)
Existing physical features provide adequate screening.
5.
Wall specifications. Required walls shall be constructed of masonry material that is architecturally compatible with the materials used on the facade of the principal structure on the site, such as face brick, decorative block, or poured concrete with simulated brick or stone patterns.
