§ 152.233 REQUIRED IMPROVEMENTS TO OFF-STREET PARKING AREAS.
   (A)   Surfacing. All open off-street parking areas having a vehicular use area greater than 10,000 square feet in size shall be graded and constructed having a minimum eight inches of #304 base overlain by at least two inches of asphalt concrete on comparable all-weather surface acceptable to the Municipal Engineer.
   (B)   Peripheral landscaping required. All open off-street parking areas shall be separated from public sidewalks and street rights-of-way by a landscaped strip at least ten feet in width, and a six-inch high barrier (curb) shall be provided on the parking lot side of the landscape strip.
   (C)   Screening. When any open off-street parking area containing more than five parking spaces is adjacent to a residential district, an effective buffer or screen, consisting of a solid wall, fence, or dense living hedge shall be provided at the lot line to protect the privacy of the adjoining residential uses. This wall, fence, or hedge shall be not less than six feet in height within side or rear yards and not more than three feet in height within a front yard.
   (D)   Lighting. Any lighting used to illuminate off-street parking areas shall be equipped with suitable shielding or be so designed as to prevent a glare at eye level on surrounding public or private property.
   (E)   Interior landscaping required. No off-street parking areas shall be constructed or enlarged until interior landscaping has been approved by the village Planning Commission and installed.
      (1)   Landscape materials. The primary landscaping materials used in such off-street parking areas shall be trees, which shall be eight feet to ten feet in minimum overall height upon planting and which provide shade or are capable of providing shade at maturity. Shrubbery, hedges, and other planting materials may be used to complement the tree landscaping. A guide of planting types deemed acceptable for landscaping purposes is on file in the office of the Zoning Inspector and should be consulted prior to design of any parking facility.
      (2)   Size of planting areas. The interior dimensions of any planting area or planting median shall be sufficient to protect the landscaping materials planted therein and to insure proper growth. In those instances where plant material exists on a proposed parking facility prior to its development, such landscape material may be used to meet the requirement of this zoning code.
      (3)   Interior requirements. Within interior vehicular use areas 10,000 square feet or greater in size, and for each additional 10,000 square foot unit or a proportional fraction thereof, a minimum total of 500 square feet of landscape area shall be provided, irrespective of the peripheral requirements. For individual parking lots with more than five parking spaces and less than 10,000 square feet in area, 5% of the vehicular use area, irrespective of the perimeter requirements, shall be devoted to landscape. Planting which is required for screening along peripheral areas of parking facilities shall not be considered as part of the interior coverage requirement.
         (a)   Required trees. A minimum of two trees, each a minimum size of 1-3/4 inches in trunk diameter, shall be provided for each 10,000 square foot unit of interior vehicular use area. The minimum distance from a tree to a vehicular use area shall be four feet measured from the face of the tree.
         (b)   Location of interior landscape area.
            1.   The interior landscape area and trees required for each 10,000 square foot vehicular use area unit, or fraction thereof, shall be located within that vehicular use area unit or fraction thereof. In areas where the Zoning Inspector has determined that the strict application of this section will interfere with the function of a vehicular use area, the unused portion of the required interior landscaping shall be relocated, upon recommendation by the Planning Commission, elsewhere on the property so as to emphasize a landscaping feature.
            2.   In order that there shall be safe access to parking spaces, landscaped strips shall be arranged so as to divide parking corridors and to limit cross movements through open parking spaces. The minimum width of any landscaped area shall be five feet.
         (c)   Credit for existing trees. If in the judgment of the Zoning Inspector it is deemed appropriate, credit may be received on the interior landscaping plan by preserving existing trees capable of tolerating adjacent construction. In order to maintain any tree deemed eligible for credit, 100% of the ground area under and within the drip line of the tree shall be preserved from the trunk out to the edge of the drip line and shall be maintained in either vegetative landscape material or pervious surface cover, except when the Zoning Inspector determines that lesser areas and other ground cover treatment will provide sufficient nourishment for the continued growth of the preserved type of tree. The required number of new trees may be reduced in accordance with the following schedule in exchange for preserving existing trees:
Diameter of Existing Crown Spread of Preserved Tree1
Diameter of Tree Trunk of Preserved Tree2
Number of Trees Credited
Diameter of Existing Crown Spread of Preserved Tree1
Diameter of Tree Trunk of Preserved Tree2

Editor's note:
   The code user should interpret the first two columns in the table above as alternatives; for example, if either the diameter of existing crown spread of a preserved tree is 90 feet or if the diameter of tree trunk of a preserved tree is 35 inches or greater, then the number of trees credited will be 7.
 
   (F)   Drainage. All open off-street parking areas shall be provided with adequate drainage facilities as approved by the Municipal Engineer. This approval will not be required for off-street parking for single-family or two-family uses.
   (G)   Maintenance. All parts of open off-street parking areas which are landscaped shall be continuously maintained and kept in a well-manicured condition.
   (H)   Marking. Designated parking spaces shall be marked on the surface of the parking area with paint or permanent marking materials and maintained in clearly visible condition.
