00.- LANDSCAPING, SCREENING, AND WALLS
A.
Intent. Landscaping, greenbelts, and screening are necessary for the continued protection and enhancement of all land uses. Landscaping and greenbelts are capable of enhancing 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. These requirements shall apply to all uses which are developed, expanded, or changed and to all lots, sites, and parcels which are developed or expanded upon following the effective date of this ordinance. No site plan shall be approved unless it shows landscaping consistent with the requirements of this section. Where landscaping is required, 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 section 2.17.
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. Generally, the most successful landscape design plans have involved clustering of trees and shrubs, rather than "formal" designs involving placement of trees and shrubs at uniform intervals.
A.
General site requirements. All developed portions of the site shall conform to the following general landscaping standards, except where specific landscape elements, such as a greenbelt, berms, or screening are required:
1.
All unpaved portions of the site shall be planted with grass, ground cover, shrubbery, or other suitable live plant material, which shall extend to any abutting street pavement edge. Grass areas in the front yard of all nonresidential uses shall be planted with sod.
2.
A mixture of evergreen and deciduous trees shall be planted on nonresidential parcels at the rate of one tree per 3,000 square feet or portion thereof of any unpaved open area for which specific landscaping requirements do not appear later in this article. Required trees may be planted at uniform intervals, at random, or in groupings.
3.
All lawn and landscaped areas shall be provided with four inches of topsoil or compost on untilled surfaces or two inches of topsoil or compost on tilled surfaces.
B.
Berms. Where required, berms shall conform to the following standards:
1.
Dimensions. Unless otherwise indicated or appropriate, required berms shall be measured from the grade of the adjacent road right-of-way or parking lot adjacent to the berm, whichever is higher, and shall be constructed with slopes no steeper than one foot vertical for each three feet horizontal (33 percent slope), with at least a two-foot flat area on top. Berms shall undulate both vertically and horizontally and the landscape plan shall show the proposed contours of the berm, subject to review and approval of berm design as shown on the site plan.
2.
Protection from erosion. Any required berm shall be planted with sod, ground cover, or other suitable live plant material to protect it from erosion so that it retains its height and shape. The use of railroad ties, cement blocks, and other types of construction materials to retain the shape and height of a berm shall be prohibited unless specifically reviewed and approved by the planning commission.
3.
Required plantings.
a.
Berms located in the front yard of nonresidential parcels. Berms located in the front yard of nonresidential parcels shall be landscaped in accordance with the requirements for landscaping adjacent to roads, section 5.03.A.3.
b.
Berms used for screening other than in the front yard. A minimum of one deciduous shade tree shall be planted for each 30 lineal feet or portion thereof, plus, a minimum of one ornamental tree shall be planted for each 50 lineal feet or portion thereof of required berm, plus, evergreen trees or hedges that are at least eight feet high as measured from the top of the root ball, which, upon being planted in two rows with staggered offset planted 15-foot on center of both rows, will create a visual barrier for at least 75 percent of the berm length.
4.
Measurement of berm length. For the purposes of calculating required plant material, berm length shall be measured along the exterior edge of the berm.
C.
Parking lot landscaping. In addition to required screening, all off-street parking areas shall also provide landscaping as follows:
1.
Landscaping ratio. Off-street parking areas containing greater than 15 spaces shall be provided with at least 25 square feet of interior landscaping per parking space, except that only ten square feet of interior landscaping shall be required per parking space located in a parking structure in the mid- and high-rise development districts, and in mobile home park, R-6, MR, and RMH districts. Whenever possible, parking lot landscaping shall be designed to improve the safety of pedestrian and vehicular traffic, guide traffic movement, and improve the appearance of the parking area.
2.
Minimum area. Landscaped areas located in parking lots and adjacent to any building wall shall be no less than 12 feet in any single dimension and no less than 150 square feet in area, except that interior landscaped areas shall measure no less than 300 square feet in area in the mid- and high-rise development districts. In the C-1 and C-2 zoning districts, any planting island located within a parking lot or located adjacent to a perimeter driveway shall be a minimum of 20 feet in any single dimension and no less than 400 square feet in area. Wherever possible, the parking areas and driveways shall be separated from the buildings by a landscaped island. Landscaped areas in or adjacent to parking lots shall be protected with curbing or other means to prevent encroachment of vehicles.
3.
Other landscaping. Required landscaping elsewhere on the parcel shall not be counted in meeting the parking lot landscaping requirements.
4.
Required plantings. Requirements for plant material shall be based on the location, size, and shape of the parking lot landscaped area. A minimum of one evergreen or deciduous shade tree shall be planted per 300 square feet or fraction thereof of interior landscaped area. At least 50 percent of each interior landscaped area shall be covered by living plant material, such as sod, shrubs, ground cover, or trees. Plantings within parking lots shall comply with the requirements for unobstructed site [sight] distance set forth in section 5.02.F, herein. The landscape plan shall indicate the types, sizes, and quantities of plant material proposed for such area.
D.
Screening.
1.
General screening requirements. Unless otherwise specified, wherever an evergreen or landscaped screen is required, evergreen screening shall consist of closely spaced plantings which can be reasonably expected to form a complete visual barrier that is at least eight feet above ground level within five years of planting. Wherever screening is required adjacent to residentially zoned or used property, the screening must be installed prior to the beginning of site grading and general construction, except where such activity would result in damage to the screening.
2.
Screening of utility substation and mechanical equipment. Mechanical equipment, such as air compressors, pool pumps, transformers, air conditioning units, sprinkler pumps, satellite dish antennas, utility substations and similar equipment shall be screened by evergreens on at least three sides. Insofar as practical, said screening shall exceed the vertical height of the equipment being screened by at least six inches within two years of planting. Specific screening requirements for utility substations will be determined on a case-by-case basis by the township depending on the particular character of the area where the substation is proposed to be located.
E.
Landscaping of rights-of-way. Public rights-of-way located adjacent to required landscaped areas and greenbelts shall be planted with sod or other suitable live ground cover, and shall be maintained by the owner or occupant of the adjacent property as if the rights-of-way were part of the required landscaped areas or greenbelts. No plantings except grass or ground cover shall be permitted closer than three feet from the edge of the road pavement.
F.
Maintenance of unobstructed visibility for drivers. No landscaping shall be erected, established, or maintained on any parcel or in any parking lot which will obstruct the view of drivers. Accordingly, all landscaping shall comply with the provisions concerning unobstructed sight distance set forth in section 2.09.A.4, herein. Furthermore, interior landscaping in parking lots shall not be permitted to obstruct cross-visibility between a height of 30 inches and six feet above the grade level of the parking lot.
G.
Potential damage to utilities. In no case shall landscaping material be planted in a way which will interfere with or cause damage to underground utility lines, public roads, or other public facilities. Species of trees whose roots are known to cause damage to public roadways, sewers, or other utilities shall not be planted closer than 15 feet from any such roadways, sewers, or utilities. A list of such tree species shall be kept on file with the planning official, and shall be made available to all interested persons upon request.
H.
Landscaping of divider medians. Where traffic on driveways, maneuvering lanes, private roads, or similar vehicle accessways is separated by a divider median, the median shall be curbed and have a minimum width of 12 feet as measured from the back of curb. A minimum of one deciduous or evergreen tree shall be planted for each 30 lineal feet or portion thereof of median. Trees may be planted at uniform intervals, at random, or in groupings, but in no instance shall the center-to-center distance between trees exceed 60 feet.
I.
Stormwater detention basins. Detention basins (ponds) shall be designed as an integral part of the overall site plan and shall be considered a natural landscape feature having an irregular shape. Planting Guidelines are available from Canton Township Planning Services upon request.
The following standards shall be considered minimum requirements for the landscaping of detention ponds/basins:
1.
Detention basin vegetation requirements. The landscape treatment for detention basins shall include a variety of native wetland and wildflower species. Native vegetation provides a number of benefits in detention basins including enhanced stormwater quality, increased habitat, passive recreational opportunities and reduced algae growth. The combination of wetland plugs and native seed mixes will provide the optimum opportunities to achieve the benefits described above. The side slopes and the bottom of the pond shall be planted with a combination of a native seed mix and wetland plugs/bare-root stock. Refer to Planting Guidelines for definitions of various native plant types in accordance with the standards outlined in this section.
a.
Planting zone definitions. Planting zones and proposed native plants, including all seed mixes, shrubs, trees, plugs and bare-root stock shall be identified on the landscape plan and referenced on the engineering site plan based on the proposed stormwater elevations in the detention basin(s). See illustration.
1.
Pond zone (depths from 0 feet to 3 feet deep). Plants in the pond zone are entirely or partially submerged, utilize nutrients from stormwater runoff and provide habitat for wildlife such as waterfowl and aquatic insects. Recommended plants in this zone must be planted according to industry standards. Minimum requirements are specified in section I.1.d, plantings and vegetation standards according to planting zone. Approved native plant species are listed in planting guidelines.
2.
Edge zone (permanent water elevation to bankfull elevation). Plants in the Edge Zone can withstand periods of inundation and drought and function to stabilize side slopes of the basin, utilize nutrients, provide habitat for waterfowl, reduce water temperatures and conceal drawdown in typical mowed ponds. Recommended plants in this zone must be planted according to industry standards. Minimum requirements are specified in section I.1.d, plantings and vegetation standards according to planting zone. Approved native plant species are listed in planting guidelines.
3.
Upland zone (bankfull elevation to 100-year flood elevation and beyond). Plants in the upland zone can withstand periods of inundation and drought and function to stabilize side slopes, provide habitat for waterfowl, songbirds and other wildlife, consist of low maintenance species as frequency of mowing will be limited, and be selected based on soil condition, light and function as little or no inundation by stormwater may occur. Recommended plants in this zone must be planted according to industry standards. Minimum requirements are specified in section I.1.d, plantings and vegetation standards according to planting zone. Approved native plant species are listed in planting guidelines.

CROSS-SECTION A-A
DETENTION BASIN PLANTING ZONES
Section 5.02, subsection I.1
b.
Detention basin categories. Depending on the location and function of a detention basin within a development, a basin will be designated into one of two possible categories. In addition, vegetation requirements within the upland zone will vary between the two categories. Furthermore, detention basins located directly behind proposed residential dwellings may be designated into either category depending on the ultimate use and intended function of the basin. The two detention basin categories are defined as follows:
1.
Highly-visible basins. Highly-visible basins include basins located at development entrances, adjacent to primary or secondary roads, adjacent to or directly behind proposed homes or are located within more formally landscaped areas in the proposed development. Seed mix for upland zone will extend from the upper boundary of the edge zone to the top of bank or slope. The area beyond the top of bank or slope of the basin shall be sodded with an approved sod material as per section 5.04, Standards for landscape materials, of the Canton Township Ordinance.
2.
Natural basins. Natural Basins include basins located adjacent to natural areas (forested areas, creeks/streams, wetlands), in remote areas, within interior areas of the development, adjacent to or directly behind proposed homes and terraced systems. Seed mix appropriate for the areas extending beyond the 100-year flood elevation and top of bank or slope and functioning as a buffer for the pond shall be a mesic-to-dry prairie mix. This mix will consist of a broad-spectrum of prairie grasses and wildflowers with species that vary in height profile and also offer a variety of cover and food options for wildlife. The natural area seeded with prairie mix must be a minimum of 15 feet wide.
c.

a.
A minimum of four plant species must be specified for the pond zone. The proposed plants shall be planted in equal numbers of species, scattered in groupings of similar species throughout the entire zone. Initial plantings shall cover a minimum of 25 percent of the outer 15-foot perimeter of the pond zone, with specific species and their appropriate water depths listed. Refer to planting guidelines for approved native plant species by planting zone.
b.
As an alternate, the pond zone may be seeded with a suitable mix if it is demonstrated that the pond hydrology will be controlled for the establishment of the proposed seed mix. Successful establishment of the seed mix will be the responsibility of the contractor. In addition, a proposed hydrologic (water-level) control plan must be reviewed by Canton's Public Works Division to ensure stormwater is properly managed on-site.
c.
No plugs will be required in the pond zone of the forebay.
2.
Edge zone. A native wetland edge or native sedge meadow seed mix shall be planted in this zone. Refer to planting guidelines for approved native seed mixes by planting zone.
3.
Upland zone. A native sedge meadow seed mix or prairie (basic, dry-to-mesic or wet-to-mesic) seed mix shall be planted in this zone. Refer to planting guidelines for approved native plant species by planting zone. The selection of seed mix and extent of installation is determined by the defined detention basin category in section I.1.b.

Off-season planting requirements. If development is completed during the off-season when plants cannot be installed, the owner shall provide a performance guarantee to ensure installation of required landscaping in the next planting season, in accordance with section 2.17.
D.
Maintenance. Landscaping required by this ordinance shall be warranted by the developer for one year from the date of acceptance by the township. Landscaping shall be continually maintained in a healthy, neat, and orderly appearance, free from weeds, refuse and debris by the owners of the property after the developer has completed all of the warranty replacements required by the township. All unhealthy and dead plant material shall be replaced immediately upon notice from the building and/or planning official, unless the season is not appropriate for planting, in which case such plant material shall be replaced at the beginning of the next planting season. An automatic irrigation system is required of all proposed developments for all landscaped and/or lawn areas. This requirement may be waived by the planning commission if it is determined that the scope of the project is minimal and that the cost of installation of such equipment would be prohibitive to the development of the site. Trees, shrubs, and other plantings and lawn areas shall be watered regularly throughout the growing season. All constructed or manufactured landscape elements, such as but not limited to benches, retaining walls, edging, the irrigation system, mulch, decorative lighting, landscape monuments, garden walls, or fencing, and so forth, shall be maintained in good condition and neat appearance. Rotted, deteriorated, or damaged landscape elements shall be repaired or replaced.
(Ord. of 1-23-2003)
The following regulations shall apply to existing plant material:
A.
Consideration of existing elements in the landscape design. 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 section and the ordinance in general.
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. Site plans shall show all existing trees which are located on the site which are six inches or greater in diameter, measured at 4½ feet above grade.
Existing trees shall be labelled "To Be Removed" or "To Be Saved" on the site plan. If existing plant material is labelled "To Be Saved" on the site plan, protective measures should be implemented, such as the placement of fencing or stakes at the dripline around each tree. No vehicle or other construction equipment shall be parked or stored within the dripline of any tree or other plant material intended to be saved. All preservation measures shall be subject to the provisions of the forest preservation ordinance [chapter 94, article II of the Township Code].
In the event that healthy existing plant materials which have been approved to meet the requirements of the ordinance are damaged or destroyed during construction or die within one year of completion of the project, said plant material shall be replaced with the same species as the damaged or removed tree, in accordance with the following schedule, unless otherwise approved by the planning official based on consideration of the site and building configuration, available planting space, and similar considerations:
_____
DIAMETER MEASURED 4½ FEET ABOVE GRADE
_____
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 section and ordinance in general. In determining whether a modification is appropriate, the planning commission shall consider whether the following conditions exist:
-
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.
-
Parking, vehicular circulation, or land use are such that required landscaping would not enhance the site or result in the desired screening effect.
-
The public benefit intended by the landscape regulations could be better achieved with a plan that varies from the strict requirements of the ordinance.
A.
Obscuring wall and fence standards. Where permitted or required by this ordinance, obscuring walls shall be subject to the following regulations:
1.
Location. Required obscuring walls and fences shall be placed inside the lot line except in the following instances:
-
Where underground utilities interfere with placement of the wall or fence on the property line, the wall shall be placed on the utility easement line located nearest the property line.
-
Walls and fences shall conform to the setback and location requirements set forth in the township fence ordinance [chapter 78, article V of the Township Code].
2.
Time of construction. Wherever construction of an obscuring wall or fence is required adjacent to residentially zoned or used property, the wall or fence must be installed prior to the beginning of site grading and general construction, except where such activity would result in damage to the wall or fence.
3.
Corner clearance. Obscuring walls and fences shall comply with the specifications for maintenance of unobstructed sight distance for drivers as set forth in section 2.09.
4.
Substitution. As a substitute for a required obscuring wall or fence, the planning commission may, in its review of the site plan, approve the use of other existing and/or proposed natural or manmade landscape features (such as closely spaced evergreens) that would produce substantially the same results in terms of screening, durability, and permanence. The character of adjoining uses and the preferences of adjoining residents or businesses shall be taken into consideration in determining whether any such substitution is appropriate.
5.
Wall specifications. Required obscuring walls shall comply with the following height requirements, unless otherwise specified in this ordinance:
Required walls shall be constructed of masonry material which matches the primary masonry of the principal structure on the site. Standard concrete block walls and poured or precast concrete walls are not permitted. Required walls shall be similarly finished on all sides.
6.
Fence specifications. Fences erected for screening purposes shall be six feet in height unless otherwise specified in this ordinance, and shall be constructed of redwood, cedar, or no. 1 pressure-treated wood. Chain link fences shall not be permitted for screening purposes. All fences shall be constructed in compliance with the township fence ordinance [chapter 78, article V of the Township Code].
(Ord. of 1-23-2003)
A.
General standards. Fences or walls in residential districts, whether for the purposes of screening or decorative landscaping, shall be subject to the regulations set forth in the township fence ordinance [chapter 78, article V of the Township Code].
B.
Entranceway structures. Residential subdivision entranceway structures shall be permitted, subject to the site plan review as landscape features. These structures shall not be considered fences or borders as defined in the township fence ordinance [chapter 78, article V of the Township Code].
00.- LANDSCAPING, SCREENING, AND WALLS
A.
Intent. Landscaping, greenbelts, and screening are necessary for the continued protection and enhancement of all land uses. Landscaping and greenbelts are capable of enhancing 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. These requirements shall apply to all uses which are developed, expanded, or changed and to all lots, sites, and parcels which are developed or expanded upon following the effective date of this ordinance. No site plan shall be approved unless it shows landscaping consistent with the requirements of this section. Where landscaping is required, 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 section 2.17.
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. Generally, the most successful landscape design plans have involved clustering of trees and shrubs, rather than "formal" designs involving placement of trees and shrubs at uniform intervals.
A.
General site requirements. All developed portions of the site shall conform to the following general landscaping standards, except where specific landscape elements, such as a greenbelt, berms, or screening are required:
1.
All unpaved portions of the site shall be planted with grass, ground cover, shrubbery, or other suitable live plant material, which shall extend to any abutting street pavement edge. Grass areas in the front yard of all nonresidential uses shall be planted with sod.
2.
A mixture of evergreen and deciduous trees shall be planted on nonresidential parcels at the rate of one tree per 3,000 square feet or portion thereof of any unpaved open area for which specific landscaping requirements do not appear later in this article. Required trees may be planted at uniform intervals, at random, or in groupings.
3.
All lawn and landscaped areas shall be provided with four inches of topsoil or compost on untilled surfaces or two inches of topsoil or compost on tilled surfaces.
B.
Berms. Where required, berms shall conform to the following standards:
1.
Dimensions. Unless otherwise indicated or appropriate, required berms shall be measured from the grade of the adjacent road right-of-way or parking lot adjacent to the berm, whichever is higher, and shall be constructed with slopes no steeper than one foot vertical for each three feet horizontal (33 percent slope), with at least a two-foot flat area on top. Berms shall undulate both vertically and horizontally and the landscape plan shall show the proposed contours of the berm, subject to review and approval of berm design as shown on the site plan.
2.
Protection from erosion. Any required berm shall be planted with sod, ground cover, or other suitable live plant material to protect it from erosion so that it retains its height and shape. The use of railroad ties, cement blocks, and other types of construction materials to retain the shape and height of a berm shall be prohibited unless specifically reviewed and approved by the planning commission.
3.
Required plantings.
a.
Berms located in the front yard of nonresidential parcels. Berms located in the front yard of nonresidential parcels shall be landscaped in accordance with the requirements for landscaping adjacent to roads, section 5.03.A.3.
b.
Berms used for screening other than in the front yard. A minimum of one deciduous shade tree shall be planted for each 30 lineal feet or portion thereof, plus, a minimum of one ornamental tree shall be planted for each 50 lineal feet or portion thereof of required berm, plus, evergreen trees or hedges that are at least eight feet high as measured from the top of the root ball, which, upon being planted in two rows with staggered offset planted 15-foot on center of both rows, will create a visual barrier for at least 75 percent of the berm length.
4.
Measurement of berm length. For the purposes of calculating required plant material, berm length shall be measured along the exterior edge of the berm.
C.
Parking lot landscaping. In addition to required screening, all off-street parking areas shall also provide landscaping as follows:
1.
Landscaping ratio. Off-street parking areas containing greater than 15 spaces shall be provided with at least 25 square feet of interior landscaping per parking space, except that only ten square feet of interior landscaping shall be required per parking space located in a parking structure in the mid- and high-rise development districts, and in mobile home park, R-6, MR, and RMH districts. Whenever possible, parking lot landscaping shall be designed to improve the safety of pedestrian and vehicular traffic, guide traffic movement, and improve the appearance of the parking area.
2.
Minimum area. Landscaped areas located in parking lots and adjacent to any building wall shall be no less than 12 feet in any single dimension and no less than 150 square feet in area, except that interior landscaped areas shall measure no less than 300 square feet in area in the mid- and high-rise development districts. In the C-1 and C-2 zoning districts, any planting island located within a parking lot or located adjacent to a perimeter driveway shall be a minimum of 20 feet in any single dimension and no less than 400 square feet in area. Wherever possible, the parking areas and driveways shall be separated from the buildings by a landscaped island. Landscaped areas in or adjacent to parking lots shall be protected with curbing or other means to prevent encroachment of vehicles.
3.
Other landscaping. Required landscaping elsewhere on the parcel shall not be counted in meeting the parking lot landscaping requirements.
4.
Required plantings. Requirements for plant material shall be based on the location, size, and shape of the parking lot landscaped area. A minimum of one evergreen or deciduous shade tree shall be planted per 300 square feet or fraction thereof of interior landscaped area. At least 50 percent of each interior landscaped area shall be covered by living plant material, such as sod, shrubs, ground cover, or trees. Plantings within parking lots shall comply with the requirements for unobstructed site [sight] distance set forth in section 5.02.F, herein. The landscape plan shall indicate the types, sizes, and quantities of plant material proposed for such area.
D.
Screening.
1.
General screening requirements. Unless otherwise specified, wherever an evergreen or landscaped screen is required, evergreen screening shall consist of closely spaced plantings which can be reasonably expected to form a complete visual barrier that is at least eight feet above ground level within five years of planting. Wherever screening is required adjacent to residentially zoned or used property, the screening must be installed prior to the beginning of site grading and general construction, except where such activity would result in damage to the screening.
2.
Screening of utility substation and mechanical equipment. Mechanical equipment, such as air compressors, pool pumps, transformers, air conditioning units, sprinkler pumps, satellite dish antennas, utility substations and similar equipment shall be screened by evergreens on at least three sides. Insofar as practical, said screening shall exceed the vertical height of the equipment being screened by at least six inches within two years of planting. Specific screening requirements for utility substations will be determined on a case-by-case basis by the township depending on the particular character of the area where the substation is proposed to be located.
E.
Landscaping of rights-of-way. Public rights-of-way located adjacent to required landscaped areas and greenbelts shall be planted with sod or other suitable live ground cover, and shall be maintained by the owner or occupant of the adjacent property as if the rights-of-way were part of the required landscaped areas or greenbelts. No plantings except grass or ground cover shall be permitted closer than three feet from the edge of the road pavement.
F.
Maintenance of unobstructed visibility for drivers. No landscaping shall be erected, established, or maintained on any parcel or in any parking lot which will obstruct the view of drivers. Accordingly, all landscaping shall comply with the provisions concerning unobstructed sight distance set forth in section 2.09.A.4, herein. Furthermore, interior landscaping in parking lots shall not be permitted to obstruct cross-visibility between a height of 30 inches and six feet above the grade level of the parking lot.
G.
Potential damage to utilities. In no case shall landscaping material be planted in a way which will interfere with or cause damage to underground utility lines, public roads, or other public facilities. Species of trees whose roots are known to cause damage to public roadways, sewers, or other utilities shall not be planted closer than 15 feet from any such roadways, sewers, or utilities. A list of such tree species shall be kept on file with the planning official, and shall be made available to all interested persons upon request.
H.
Landscaping of divider medians. Where traffic on driveways, maneuvering lanes, private roads, or similar vehicle accessways is separated by a divider median, the median shall be curbed and have a minimum width of 12 feet as measured from the back of curb. A minimum of one deciduous or evergreen tree shall be planted for each 30 lineal feet or portion thereof of median. Trees may be planted at uniform intervals, at random, or in groupings, but in no instance shall the center-to-center distance between trees exceed 60 feet.
I.
Stormwater detention basins. Detention basins (ponds) shall be designed as an integral part of the overall site plan and shall be considered a natural landscape feature having an irregular shape. Planting Guidelines are available from Canton Township Planning Services upon request.
The following standards shall be considered minimum requirements for the landscaping of detention ponds/basins:
1.
Detention basin vegetation requirements. The landscape treatment for detention basins shall include a variety of native wetland and wildflower species. Native vegetation provides a number of benefits in detention basins including enhanced stormwater quality, increased habitat, passive recreational opportunities and reduced algae growth. The combination of wetland plugs and native seed mixes will provide the optimum opportunities to achieve the benefits described above. The side slopes and the bottom of the pond shall be planted with a combination of a native seed mix and wetland plugs/bare-root stock. Refer to Planting Guidelines for definitions of various native plant types in accordance with the standards outlined in this section.
a.
Planting zone definitions. Planting zones and proposed native plants, including all seed mixes, shrubs, trees, plugs and bare-root stock shall be identified on the landscape plan and referenced on the engineering site plan based on the proposed stormwater elevations in the detention basin(s). See illustration.
1.
Pond zone (depths from 0 feet to 3 feet deep). Plants in the pond zone are entirely or partially submerged, utilize nutrients from stormwater runoff and provide habitat for wildlife such as waterfowl and aquatic insects. Recommended plants in this zone must be planted according to industry standards. Minimum requirements are specified in section I.1.d, plantings and vegetation standards according to planting zone. Approved native plant species are listed in planting guidelines.
2.
Edge zone (permanent water elevation to bankfull elevation). Plants in the Edge Zone can withstand periods of inundation and drought and function to stabilize side slopes of the basin, utilize nutrients, provide habitat for waterfowl, reduce water temperatures and conceal drawdown in typical mowed ponds. Recommended plants in this zone must be planted according to industry standards. Minimum requirements are specified in section I.1.d, plantings and vegetation standards according to planting zone. Approved native plant species are listed in planting guidelines.
3.
Upland zone (bankfull elevation to 100-year flood elevation and beyond). Plants in the upland zone can withstand periods of inundation and drought and function to stabilize side slopes, provide habitat for waterfowl, songbirds and other wildlife, consist of low maintenance species as frequency of mowing will be limited, and be selected based on soil condition, light and function as little or no inundation by stormwater may occur. Recommended plants in this zone must be planted according to industry standards. Minimum requirements are specified in section I.1.d, plantings and vegetation standards according to planting zone. Approved native plant species are listed in planting guidelines.

CROSS-SECTION A-A
DETENTION BASIN PLANTING ZONES
Section 5.02, subsection I.1
b.
Detention basin categories. Depending on the location and function of a detention basin within a development, a basin will be designated into one of two possible categories. In addition, vegetation requirements within the upland zone will vary between the two categories. Furthermore, detention basins located directly behind proposed residential dwellings may be designated into either category depending on the ultimate use and intended function of the basin. The two detention basin categories are defined as follows:
1.
Highly-visible basins. Highly-visible basins include basins located at development entrances, adjacent to primary or secondary roads, adjacent to or directly behind proposed homes or are located within more formally landscaped areas in the proposed development. Seed mix for upland zone will extend from the upper boundary of the edge zone to the top of bank or slope. The area beyond the top of bank or slope of the basin shall be sodded with an approved sod material as per section 5.04, Standards for landscape materials, of the Canton Township Ordinance.
2.
Natural basins. Natural Basins include basins located adjacent to natural areas (forested areas, creeks/streams, wetlands), in remote areas, within interior areas of the development, adjacent to or directly behind proposed homes and terraced systems. Seed mix appropriate for the areas extending beyond the 100-year flood elevation and top of bank or slope and functioning as a buffer for the pond shall be a mesic-to-dry prairie mix. This mix will consist of a broad-spectrum of prairie grasses and wildflowers with species that vary in height profile and also offer a variety of cover and food options for wildlife. The natural area seeded with prairie mix must be a minimum of 15 feet wide.
c.
Site plan and landscape plan submittal. The site plan submittal shall include a plan sheet for the detention basin(s) that identifies the following items:

Plan view of the detention basin, including one-foot grading contours.
•
Elevations in the detention basin including pond bottom elevation, permanent water elevation, bankfull storm elevation, 100-year storm elevation and freeboard elevation.
•
Area in square feet of the pond zone, edge zone and upland zone.
•
Required seed mixes and wetland plugs/bare root stock in the three planting zones as per section I.1.d, Plantings and vegetation standards according to planting zone. The required seed mixes, wetland plugs/bare-root stock shall be subject to approval by the planning services division.
•
Plant spacing and applicable depths shall be specified based on recommended industry standards.
d.
Plantings and vegetation standards according to planting zone. Landscape plans shall identify the proposed native plants for each of the planting zones defined in I.1.a., Planting zone definitions. Minimum landscape requirements are defined as follows:
1.
Pond zone. A combination of native plant plugs and bare-root stock (submerged, emergent and wetland edge plugs) shall be planted within the pond zone. This zone ranges in depth from zero feet to three feet deep. Proposed plant species:
a.
A minimum of four plant species must be specified for the pond zone. The proposed plants shall be planted in equal numbers of species, scattered in groupings of similar species throughout the entire zone. Initial plantings shall cover a minimum of 25 percent of the outer 15-foot perimeter of the pond zone, with specific species and their appropriate water depths listed. Refer to planting guidelines for approved native plant species by planting zone.
b.
As an alternate, the pond zone may be seeded with a suitable mix if it is demonstrated that the pond hydrology will be controlled for the establishment of the proposed seed mix. Successful establishment of the seed mix will be the responsibility of the contractor. In addition, a proposed hydrologic (water-level) control plan must be reviewed by Canton's Public Works Division to ensure stormwater is properly managed on-site.
c.
No plugs will be required in the pond zone of the forebay.
2.
Edge zone. A native wetland edge or native sedge meadow seed mix shall be planted in this zone. Refer to planting guidelines for approved native seed mixes by planting zone.
3.
Upland zone. A native sedge meadow seed mix or prairie (basic, dry-to-mesic or wet-to-mesic) seed mix shall be planted in this zone. Refer to planting guidelines for approved native plant species by planting zone. The selection of seed mix and extent of installation is determined by the defined detention basin category in section I.1.b.
4.
Seed mixes, general. All seed mixes must include at least five to six native permanent grass/sedge/rush species and nine to ten native forb species. Seed mixes shall also contain a minimum of 100 ounces per acre annual rye and 360 ounces per acre seed oats as a temporary cover crop in order to provide cover and establish soil stability for the first winter. This nurse crop will minimize weed growth in the first year.
2.

4.
[Screening.] The area around the detention basin riser outlet structure(s) (outlet between forebay and basin and primary outlet to creek/storm sewer) shall be appropriately screened with vegetation appropriate for the applicable pond zone. The screening vegetation shall not inhibit future maintenance access to the structure. Refer to planting guidelines for approved shrub and tree species for detention basins.
5.
Native plant installation: Seeding vs. planting of plugs/bare-root stock.
a.
Native seed mixes shall include an annual cover crop consisting of ten pounds/acre of annual rye and 30 pounds/acres of seed oats in accordance with industry standards in order to provide cover and establish soil stability for the first winter. The planting zone shall be roto-tilled to a depth of six inches and supplemented with an additional four inches of topsoil or compost. All areas seeded in accordance with this ordinance requirement shall be properly stabilized with a mulch blanket pegged-in-place. A barrier/wildlife-deterrent fence is required for a period of one year to protect the planting and prevent regular mowing.
b.
If emergent plant stock is proposed in the pond zone, the supplied plug material must have sufficient vegetative growth extending out of the water once planted.
c.
Native seed shall be planted above the permanent water elevation.
d.

(Ord. of 1-23-2003)
The following regulations shall apply to existing plant material:
A.
Consideration of existing elements in the landscape design. 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 section and the ordinance in general.
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. Site plans shall show all existing trees which are located on the site which are six inches or greater in diameter, measured at 4½ feet above grade.
Existing trees shall be labelled "To Be Removed" or "To Be Saved" on the site plan. If existing plant material is labelled "To Be Saved" on the site plan, protective measures should be implemented, such as the placement of fencing or stakes at the dripline around each tree. No vehicle or other construction equipment shall be parked or stored within the dripline of any tree or other plant material intended to be saved. All preservation measures shall be subject to the provisions of the forest preservation ordinance [chapter 94, article II of the Township Code].
In the event that healthy existing plant materials which have been approved to meet the requirements of the ordinance are damaged or destroyed during construction or die within one year of completion of the project, said plant material shall be replaced with the same species as the damaged or removed tree, in accordance with the following schedule, unless otherwise approved by the planning official based on consideration of the site and building configuration, available planting space, and similar considerations:
_____
DIAMETER MEASURED 4½ FEET ABOVE GRADE
_____
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 section and ordinance in general. In determining whether a modification is appropriate, the planning commission shall consider whether the following conditions exist:
-
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.
-
Parking, vehicular circulation, or land use are such that required landscaping would not enhance the site or result in the desired screening effect.
-
The public benefit intended by the landscape regulations could be better achieved with a plan that varies from the strict requirements of the ordinance.
A.

Walls and fences shall conform to the setback and location requirements set forth in the township fence ordinance [chapter 78, article V of the Township Code].
2.
Time of construction. Wherever construction of an obscuring wall or fence is required adjacent to residentially zoned or used property, the wall or fence must be installed prior to the beginning of site grading and general construction, except where such activity would result in damage to the wall or fence.
3.
Corner clearance. Obscuring walls and fences shall comply with the specifications for maintenance of unobstructed sight distance for drivers as set forth in section 2.09.
4.
Substitution. As a substitute for a required obscuring wall or fence, the planning commission may, in its review of the site plan, approve the use of other existing and/or proposed natural or manmade landscape features (such as closely spaced evergreens) that would produce substantially the same results in terms of screening, durability, and permanence. The character of adjoining uses and the preferences of adjoining residents or businesses shall be taken into consideration in determining whether any such substitution is appropriate.
5.
Wall specifications. Required obscuring walls shall comply with the following height requirements, unless otherwise specified in this ordinance:
Required walls shall be constructed of masonry material which matches the primary masonry of the principal structure on the site. Standard concrete block walls and poured or precast concrete walls are not permitted. Required walls shall be similarly finished on all sides.
