The Planning Board may require a landscape plan be prepared as part of any special use or site plan review application. Such a plan may also be required whenever any nonresidential 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 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 or waived by the Planning Board. The landscape plan, if required, shall specify locations of all mature shade trees or other species of six-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 Planning Board, in reviewing a landscape plan, may employ the assistance of design professionals. The Planning Board shall also specifically consider the following before approving, approving with modifications or disapproving the special use:
A.
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.
B.
The plant material selected should be of complementary character to buildings, structures and native plant species and be of sufficient size and quality to accomplish its intended purposes. Ornamental and shade trees should have a caliper of no less than three inches, evergreen trees should be a minimum of five feet in height and other shrubs a minimum of 24 inches in height or two gallon size, when planted.
C.
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.
D.
The plan should be realistic in terms of maintenance and use materials which, as a minimum, are winter hardy to Zone 4.
