The permitting board may require a landscape plan be prepared as part of any special use application. Such a plan may also be required whenever any non-residential and non-agricultural use is proposed in any district so as to buffer parking areas and buildings from the highway, each other and other uses. Where it is determined that a proposed special use would not have a significant impact on the natural environment, adjoining landowners or the view from a public highway, these requirements may be appropriately modified by the permitting board. The landscape plan, if required, shall specify locations of all mature shade trees or other species of 2.5-inch caliper or greater and indicate existing vegetation to be removed or preserved. It shall demonstrate how building materials, colors, and textures will be blended with the natural and man-made landscape. It shall also include visual depictions of the proposed landscape from the perspective of persons who will view the site from the highway or adjoining properties. Specific locations, varieties, sizes, winter hardiness, and schedules for all proposed plantings shall, too, be provided as part of the plan. The permitting board, in reviewing a landscape plan, may employ the assistance of design professionals and shall specifically consider the following in acting upon the special use application:
The plan should promote attractive development, preserve existing vegetation to the maximum extent possible, enhance the appearance of the property and complement the character of the surrounding area.
The plan should use landscaping to delineate or define vehicular and pedestrian ways and open space.
The plant material selected should be of complementary character to buildings, structures, and native plant species. It should be of sufficient size and quality to accomplish its intended purposes. All ornamental and shade trees should have a minimum caliper of 2.5 inches measured four feet above the ground and a minimum height of six feet. All shrubs should be a minimum of two feet in height excepting for ground cover species used as part of an overall plan including other shrubs and trees.
The plan should effectively buffer the activity from adjoining land uses as may be necessary and soften the impact of other site development as contrasted with the natural environment.
The plan should be realistic in terms of maintenance and use materials that, as a minimum, are winter hardy to Zone 5.
