Boonville Parking lot landscaping ordinance (Appendix C, Section 15.5)

1. Applicability: Landscape plantings shall be installed on any parking lots containing more than ten spaces.

2. Plan/plan review: A preliminary landscaping plan for parking lot landscaping shall accompany the preliminary site plan and contain the general description of the proposed landscaping. The final landscaping plan shall accompany the final site plan and contain all the detail to comply with the standards set forth in this Code for review and recommendation by the planning and zoning commission and review and approval by the city council.

3. Requirements:

a. Plantings may be in the public right-of-way adjacent to the parking lot; however, care should be given not to plant large species or to plant under, on or around utility easements and permission must be obtained from the utility prior to plan approval.

b. Plantings shall consist of the number of standard canopy trees needed to shade at least 35 percent of the parking lot when the trees are mature, however, plantings should not adversely affect traffic flow, traffic sight distance, or other traffic safety issues within the parking lot or at the points of ingress and egress.

c. All landscaped areas shall be protected from vehicular encroachment by curbing or anchored wheel stops. Planting islands shall be at least four feet wide and 100 square feet to protect trees and vegetation from bumper overhang and swinging doors. Plantings shall be located to minimize damage caused by car doors and bumpers.

d. Areas between trees shall be covered with shrubs, grass or other living groundcover or nonliving groundcover.

e. No parking area shall contain more than 150 spaces. If a greater number is required, separate parking spaces of not more than 150 spaces shall be provided and shall be separated by a landscaped area at least ten feet in width. The use of berms and evergreen trees in the landscaped strip is encouraged but not mandated. Up to ten percent of the length of the strip may be opened to permit pedestrian and vehicular access between parking areas. In these large parking lot areas, the amount of shade provided by mature parking lot trees may be reduced to 25 percent in cases where the landscape plan makes effective use of berms, landscape strips or landscaped areas within the interior of the parking lot. A minimum of three different species of trees is required in large parking lots to reduce the impact of potential disease or insect infestations and to provide variety in shape, texture and color.

f. Plantings shall be installed in accordance with the plan approved and in accordance with the standards of the Urban and Community Forestry Division of the Missouri Department of Conservation.

g. All plants shall be maintained in a healthy condition in accordance with generally accepted professional horticultural and arboricultural standards and practices such as recommended in ANSI Standard A-300. Plants which die or are unhealthy shall be replaced. Regular pruning and trimming shall be applied to maintain health and to permit the plants to achieve their intended form and height.
