• Section 5.10 Landscaping, Greenbelts, Buffers, and Screening.
   (a)   Intent. 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 non-compatible 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 soil water retention. It is further the intent of this section to ensure an appropriate mixture of plant material, such as evergreens, deciduous trees and shrubs, as a protective measure against insect and disease infestation and to produce a more aesthetic and cohesive design.
   (b)   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 depicts landscaping, greenbelt buffers, and screening consistent with the requirements set forth herein.
   (c)   Landscape Plan Required. A separate detailed landscape plan shall be required to be submitted as part of the site plan review. On sites of greater than one (1) acre, landscape plans shall be prepared and sealed by a registered landscape architect, licensed in the State of Michigan. The landscape 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)   The minimum scale shall be 1" = 40' for property less than five (5) acres, or 1" = 100' for property five (5) acres or more. A different scale may be used provided it is sufficient to properly illustrate the landscape plan concept and that Ordinance requirements are met.
      (3)   On parcels of more than one (1) acre, existing and proposed contours on-site and fifty (50) feet beyond the site at intervals not to exceed two (2) 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, 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 of proposed plant materials.
      (7)   Identification of existing wetlands, forested areas, 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 a statement that all diseased, damaged, or dead materials shall be replaced in accordance with standards of this section.
      (10)   Identification of mulch in planting beds.
   (d)   Screening Between Land Uses.
      (1)   Upon any improvement for which a site plan is required, excluding duplexes, a landscape buffer shall be constructed to create a visual screen at least six (6) feet in height along all adjoining boundaries with residentially zoned or used property, as well as along all parcels abutting the I-96 corridor. A landscape buffer may consist of earthen berms and/or living materials so as to maintain a minimum opacity of at least eighty (80) percent. Opacity shall be measured by observation of any two (2) square yard areas of landscape screen between one (1) foot above the established grade of the area to be concealed and the top or the highest point of the required screen. The plantings must meet this standard based upon reasonably anticipated growth over a period of three (3) years.
      (2)   Where there is a need to provide a greater noise or dust barrier or to screen more intense development, a solid wall or fence shall be required. Such wall or fence shall be a minimum of six (6) feet in height as measured on the side of the proposed wall having the higher grade.
   A required wall shall be located on the lot line except where underground utilities interfere and except in instances where this Zoning Ordinance requires conformity with front yard setback requirements. Upon review of the landscape plan, the Planning Commission may approve an alternate location of a wall. A required wall may be located on the opposite side of an alley right-of-way from a non-residential district that abuts a residential district or use when mutually agreeable to affected property owners and the Planning Commission. The continuity of the required wall on a given block shall be a major consideration of the Planning Commission in reviewing such a request. The Planning Commission and the Zoning Administrator shall approve the construction materials of the wall or fence, which may include face brick, poured- in-place simulated face brick, precast brick face panels having simulated face brick, stone or wood.
      (3)   For off-street parking areas located either within a P-1 or other district, there shall be provided and maintained a solid wall of at least four (4) feet in height on those sides where the parking area abuts a residentially zoned or used property. When a front yard setback is required, all land between the wall and the front property line or street right-of-way line shall be kept free from refuse and debris and shall be landscaped with deciduous shrubs, evergreen material and ornamental trees. The ground area shall be planted and kept in lawn.
   (e)   Parking Lot Landscaping. Separate landscaped areas shall be required either within or at the perimeter of parking lots. There shall be one (1) tree for every eight (8) parking spaces, with a minimum landscaped space within a designated parking area of fifty (50) square feet. A minimum distance of three (3) feet shall be established between proposed tree or shrub plantings and the backside of the curb or edge of the pavement. See Figures 4 and 16 in the Appendix for a depiction of landscaping options for parking lots.
   (f)   Greenbelt Buffers. The greenbelt, which is equal to the minimum required yard setback of its zoning classification, shall be landscaped with a minimum of one (1) tree per each thirty (30) linear feet. All greenbelt trees shall be no less than twelve (12) feet in height or a minimum caliper of two and one-half (2.5) inches (whichever is greater at the time of planting). The remainder of the greenbelt shall be landscaped with grass, ground cover, shrubs, and/or other natural landscape material. Access ways from public rights-of-way through required landscape strips shall be permitted, but such access ways shall not be subtracted from the linear dimension used to determine the minimum number of trees required, unless such calculation would result in a violation of the spacing requirement set forth in this section. However, when an unusual or limiting hardship exists that is not self-created, the Planning Commission may waive the side and/or rear greenbelt requirements.
   (g)   Site Landscaping. In addition to any landscape greenbelt and/or parking lot landscaping required by this section, ten (10) percent of the site area, excluding existing thoroughfare right-of-way, shall be landscaped. Such site area landscaping may include a combination of the preservation of existing tree cover, planting of new trees and plant material, landscape plazas and gardens and building foundation planting beds. Site area landscaping shall be provided to screen potentially objectionable site features, such as, but not limited to, retention/detention ponds, transformer pads, air-conditioning units, and loading areas. See Figure 17 in the Appendix for a depiction of example site landscaping.
   Up to five (5) percent of the net site area in a required landscape area may consist of landscaped areas used for storm drainage purposes, such as drain courses and retention areas, which are located in front or side yards, subject to the following conditions:
      (1)   The area may not have a slope greater than one (1) on six (6).
      (2)   The area within a fenced drain course or retention pond may not be included in the required landscape area.
      (3)   Drain courses or stream bottoms may not be included in the required landscape area.
      (4)   Materials used to landscape these areas must be those which will not be damaged by intermittent water conditions and shall be maintained in a healthy and growing condition as well as being neat and orderly in appearance.
   (h)   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 Livingston County, conform to the current minimum standard of the American Association of Nurserymen, and have proof of any required governmental regulations and/or inspections.
      (2)   Berms. Berms shall be constructed with slopes not to exceed a 1:3 gradient. Berm slopes shall be protected with sod, seed, or other form of natural ground cover.
      (3)   Existing Trees. If existing plant material is labeled "To Remain" on site plans by the applicant or required by the City, protective techniques, such as, but not limited to, fencing or barriers placed at the drip line 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 drip line of any plant material intended to be saved. Other protective techniques may be used provided such techniques are approved by the City.
   In the event that healthy trees which are used to meet the minimum requirements of this section or those labeled to remain are cut down, destroyed, damaged, or excavated at the drip line, as determined by the City, the contractor shall replace them with trees which meet Ordinance requirements.
      (4)   Installation, Maintenance, and Completion. All landscaping required by this section shall be planted prior to obtaining a certificate of occupancy. Cash, a letter of credit, and/or a certified check may shall be placed in escrow in the amount of the cost of landscaping to be released only after landscaping is completed.
      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.
   The owner of property required to be landscaped by this section 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.
   (i)   Screening of Trash Containers.
      (1)   Outside trash disposal containers shall be screened on three (3) sides with a solid wall no less than one (1) foot taller than the dumpster and no less than six (6) feet in height, while the fourth side shall consist of a lockable fence of equal height. See Figure 18 in the Appendix for a depiction of a typical trash container screen.
      (2)   Containers shall be consolidated to minimize the number of collection sites, and located so as to reasonably equalize the distance from the building they serve.
      (3)   Containers and enclosures shall be located away from public view insofar as possible.
      (4)   Containers and enclosures shall be situated so that they do not cause excessive nuisance or offense to occupants of nearby buildings.
      (5)   Concrete pads of appropriate size and construction shall be provided for containers or groups of containers having a capacity of six (6) thirty (30) gallon cans or more. Aprons shall be provided for loading of bins with capacity of 1.5 cubic yards or more.
      (6)   For storage of recyclable materials, the enclosure area and pad size shall be increased to amply accommodate the extra materials and their containers.
      (7)   Screening and gates shall be of a durable construction. Fences, walls, footings, slabs, and curbs shall meet Building Code requirements. Gates shall be constructed of heavy-gauge metal or of a heavy-gauge metal frame with covering of wood or other suitable material. Gates shall be secured with sturdy hinges or sliders and latches. If the enclosure is situated directly adjacent to parking spaces or drives, it shall be protected at its base by concrete curb blocks.
   (j)   Entranceway Structures. In residential districts, so-called entranceway structures (including, but not limited to, walls, columns and gates), marking entrances to one-family subdivisions or multiple family housing projects, may be permitted and may be located in a required yard, except as otherwise provided in Section 5.06, provided that such entranceway structures comply with all codes and ordinances of the City, are approved by the Zoning Administrator and have a permit issued therefore.
   (k)   Trees in the Right-of-Way. All trees proposed to be located within the public right-of-way shall be subject to approval by the Livingston County Road Commission and/or Michigan Department of Transportation, and shall prohibit the planting of the following tree species:
   Silver Maple         Tree of Heaven   Northern Catalpa      Poplar
   American Elm         Box Elder      Norway Maple      Willow
   Eastern Red Cedar      Chinese Elm      Siberian Elm
Additionally, all trees planted in the right-of-way shall comply with Section 5.06, visibility requirements are provided in this Zoning Ordinance.
