1105.11 LANDSCAPING AND BUFFERING.
   (a)   Purpose and Intent. These standards are intended to establish landscaping regulations that:
      (1)   Improve the aesthetic appearance of setback areas, common open space areas, public rights-of- way and off-street vehicular parking areas;
      (2)   Encourage the preservation of existing trees and natural features;
      (3)   Promote compatibility among different land uses;
      (4)   Promote the use of generally accepted landscape design principles; and
      (5)   Protect public health, safety and welfare by minimizing the impact of all forms of physical and visual pollution, controlling soil erosion, screening unsightly areas, preserving the integrity of neighborhoods and enhancing pedestrian and vehicular traffic and safety.
   (b)   Application. A landscape plan and tree survey shall be required in conjunction with any application for a zoning certificate, a variance, a conditional use permit, a similar use determination, a subdivision plat, or a site plan and design review approval. Such landscape plan and tree survey shall include the following:
      (1)   The present location, size, and description of all existing major trees, with a designation of existing major trees sought to be removed.
      (2)   The location, size and description of landscaping materials proposed to be placed on the lot in order to comply with this section.
      (3)   The location and size of any structures presently on the lot, and those proposed to be placed on the lot.
      (4)   The proposed location and description of screening to be placed on the lot in order to comply with this section.
   (c)   General Landscape Provisions.
      (1)   No zoning certificate, variance, conditional use permit, similar use determination, subdivision plat or site plan and design approval shall be granted until a landscape plan is approved in accordance with this Section.
      (2)   No landscaped area shall be used for display and/or storage purposes.
      (3)   The species, location and spacing of trees and shrubs planted in all public rights-of-way and on all sites shall be subject to approval by the Building and Zoning Inspector.
      (4)   No Certificate of Occupancy shall be granted until all conditions herein have been met; however, in the event landscaping cannot be completed due to weather conditions, or peculiar conditions related to the development of the subject property such as conditions related to phased development, the applicant shall provide financial security, in a form acceptable to the Village, in the amount of one hundred twenty-five percent (125%) of the cost of materials and installation of all remaining landscaping to be completed and an estimate of such costs in order to be eligible for a Certificate of Occupancy.
      (5)   When phasing development upon a property, a proportionate share of landscaping acceptable to the Village shall be installed and maintained with each phase based on the size of the proposed phase and shall be considered completed for the purposes of these regulations when such proportionate share of landscaping has been installed, unless special circumstances warrant the installation of a greater amount of landscaping with any phase.
      (6)   The developer and/or property owner shall be responsible for the installation and maintenance of all landscaping, buffering, perimeter treatment and screening improvements in a healthy condition. This provision shall also apply to single-family and two-family dwellings.
      (7)   Bare earth shall not be considered landscaping or a landscaped area for the purposes of meeting the landscape requirements herein. Land area shall be considered "covered" if it is used for growing grass, shrubs, trees, plants or flowers, or if covered by decorative rock, stone or wood chips, or otherwise landscaped as provided herein. This provision shall also apply to single-family and two-family dwellings.
      (8)   These landscaping provisions are not intended to require multiple or overlapping setbacks, buffers and perimeter treatments. When more than one (1) such standard applies, that standard which results in the higher landscaping or buffering requirement shall apply. Buffering and perimeter treatments may be located within the required setbacks and may be counted toward required open space except not as usable open space.
      (9)   Utility easements which conflict with required buffer yards, perimeter treatment, parkway or median standards may require an alternative design approach to address such conflicts.
   (d)   Tree Preservation. Unless exempted in accordance with this subsection, all existing major trees shall be preserved. The Building Inspector may approve the cutting down, removal or destruction of a major tree/trees when the tree or trees interferes with the proper development of the lot, provided that the lot is the subject of an application for approval of a zoning certificate, development plan approval or variance, such application is approved and one of the following applies:
      (1)   The tree or trees will be located within the public right of way.
      (2)   The subject property cannot be arranged in a manner to avoid removal of the tree or trees at the same time permitting the desirable and logical development of the lot.
      (3)   The tree/trees are located within the proposed driveway to service a single-family home, and such driveway cannot otherwise be relocated.
      (4)   The tree is damaged or diseased or can be proven to be of poor quality.
      (5)   The tree/trees are an undesirable species in its present location
   (e)   Tree Replacement. Each existing major tree removed in accordance with subsection (d) above shall be replaced with one (1) tree, having a minimum caliper of one and three-quarters inch (1 3/4") as measured one foot (1') above ground level.
   (f)   General Landscape Standards.
      (1)   The following standards shall ensure that landscaping is used to improve the aesthetic quality of a development or site in addition to providing a functional purpose and year-round interest and/or screening.
      (2)   The size of landscape elements and materials shall meet minimum standards and be consistent with the size of the project and any existing streetscape. Minimum plant sizes are as follows:
      (3)   Landscaping in parking areas, driveway entrances and intersections shall be designed to meet the minimum clear sight triangle as defined in the Zoning Code.
      (4)   Monoculture, or the extensive use of a single species of trees, shall be limited in order to minimize the potential for disease or pests to strike a particular species resulting in significant same-species loss. The following limits shall apply:
