§ 194.109  URBAN LANDSCAPING REQUIREMENTS.
   (A)   Intent. Landscaping of required yards and required bufferyards is an essential element of the design of a site with respect to promoting the public health, safety, comfort, convenience and general welfare of the town. Landscaping is intended to lessen the impact of development on the environment by reducing glare and heat buildup, promoting the creation of landscape islands for pedestrian safety, to break up large expanses of pavement, and to reduce storm water run-off. Landscaping provides a critical buffering effect between higher intensity districts and lower intensity districts (e.g., typically between business or industrial districts and abutting or adjacent residential and specific special use (SU) districts).
   (B)   Landscaping of required front, side and rear yards, required front, side and rear perimeter yards, and required front, side and rear bufferyards in all business, industrial and multi-family residential districts.
      (1)   Required front, side and rear yards in business and industrial districts shall be landscaped in compliance with the following.
         (a)   Required front yard. Landscaping in the required front yard shall consist of trees planted in accordance with one of the following alternatives.
            1.   If deciduous shade (overstory) trees are used: there shall be one tree planted at a maximum of every 40 feet on center of linear distance along all required front yards. These required trees may be grouped together in the required front yard; however, in no case shall spacing between the trees exceed 80 feet.
            2.   If deciduous ornamental (understory) trees are used: there shall be one tree planted at a maximum of every 25 feet on center of linear distance along all required front yards. These required trees may be grouped together in the required front yard; however, in no case shall spacing between the trees exceed 50 feet.
         (b)   Required side yard and required rear yard. Landscaping in the required side yard and required rear yard shall consist of trees planted in accordance with one of the following alternatives.
            1.   If deciduous shade (overstory) trees are used: there shall be one tree planted at a maximum of every 50 feet on center of linear distance along all required side yards and required rear yards. These required trees may be grouped together in the required side yard and required rear yard; in no case shall spacing between the trees exceed 80 feet.
            2.   If deciduous ornamental (understory) trees are used: there shall be one tree planted at a maximum of every 35 feet on center of linear distance along all required side yards and required rear yards. These required trees may be grouped together in the required side yard and required rear yard; however, in no case shall spacing between the trees exceed 50 feet. Deciduous shade trees and deciduous ornamental trees may be grouped together in the required yards, however, in no case shall spacing between a deciduous shade tree and a deciduous ornamental tree exceed 50 feet. The minimum size of all required landscape plant materials, at the time of planting, shall comply with the plant sizes listed in Table 12.
      (2)   Required front, side and rear bufferyards in all business and industrial districts, and front, side and rear perimeter yards in the R-MF-1 and R-MF-2 Districts shall be landscaped in compliance with the requirements of Table 12.
   (C)   Foundation planting in business and industrial districts (except the VBD, Village Business District).
      (1)   Foundation planting areas shall be required for all new buildings and building additions in all business and industrial districts (except the VBD-Village Business District).
      (2)   In the case of a single use site or a primary building in an integrated center located on a business district, foundation planting areas are required along the front and side of the building. In the case of a building located on an outlot in a business district or any building located in an industrial district, the front, side and rear of the building shall have foundation planting areas.
      (3)   Foundation planting areas shall be subject to the following requirements.
         (a)   Foundation planting areas shall be calculated individually for each applicable front, side or rear of a building and shall be located along such front, side or rear of a building (except for those portions of the front or side of a building devoted to pedestrian ingress/egress, vehicular ingress/egress, loading or drop-off zones).
         (b)   Foundation planting areas shall have a total area in square feet of not less than two feet times the length of the wall (two feet by length of wall equals area for foundation planting) to which the foundation planting is oriented.
         (c)   Foundation planting areas shall be located:
            1.   Adjacent to the building; or
            2.   So as to begin within ten feet of the building (in the case of a sidewalk which runs adjacent to the building).
         (d)   Foundation planting areas shall maintain a minimum depth in the smallest dimension of six feet.
         (e)   Foundation planting areas shall be landscaped with grass and shrubbery, trees or hedge, or in combination with other suitable ground cover materials and maintained as a foundation planting strip in compliance with the requirements for a Level A plantings as set forth in Table 12.
   (D)   Parking lot landscaping in business and industrial districts.
      (1)   Interior parking lot landscaping in business and industrial districts.

Each interior landscape island shall contain at least one deciduous shade (overstory) tree, deciduous ornamental (understory) tree or evergreen tree. All trees shall comply with the size at time of planting as indicated in Table 12.
         (b)   Space devoted to interior landscape islands shall be in addition to any required front, side or rear yards, required front, side or rear bufferyards, or required foundation plantings.
         (c)   The area devoted to interior landscape islands may be located individually in the interior of the parking lot or may be aggregated into one or more landscape areas. When located individually, interior landscape islands shall be located so as to define vehicular and pedestrian traffic patterns. When aggregated into one or more landscape areas, interior landscape islands shall function to:
            1.   Preserve existing trees;
            2.   Create boulevard treatments;
            3.   Create landscape features;
            4.   Create common open space areas for passive recreational activities; or
            5.   Define vehicular and pedestrian traffic patterns.
         (d)   Each tree shall be a minimum of two and one-half feet away from the outside of any permanent barrier of a landscaped area or edge of the parking area.
      (2)   Perimeter landscaping of parking lots in business and industrial districts. In addition to landscaping provided in required yards and required bufferyards, if a parking area is located between a building and a required front yard or between a building and a required front, side or rear bufferyard.
