A. Type I - Screen. Type I landscaping shall generally consist of a mix of predominantly evergreen plantings including living trees, shrubs and ground covers. Evergreen trees shall be a minimum height of four feet at time of planting. Plantings shall be chosen and spaced so as to grow together within three years sufficient to obscure sight through the barrier. The entire planting strip shall be landscaped; however, those plantings used to achieve the sight-obscuring screen shall cover at least five feet of the width of the strip, and shall be located farthest from the property line. Existing vegetation may be incorporated into the landscape providing it contributes to achieving the intent of this subsection. See Figure L-1.

B. Type II - Visual Buffer. Type II landscaping shall consist of a mix of evergreen and deciduous plantings including living trees, shrubs and ground covers. Plantings of shrubs and ground covers shall be chosen and spaced to result in a total covering of the landscape strip. Shrubs shall be of a type that achieve a height of approximately six feet within three years, and effectively screen views along the length of the planting strip. Deciduous trees shall have a minimum trunk diameter of one and three-quarter inches at time of planting; evergreen trees shall be a minimum four feet tall at time of planting. All trees shall be spaced at intervals resulting in touching of branches after ten years of normal growth. Trees shall be staggered in two or more rows when the minimum width of the landscaping strip is twenty (20) feet or more. Existing vegetation may be incorporated into the landscape design provided it contributes to achieving the intent of this subsection. See Figure L-1.

C. Type III - See Through Buffer. Type III landscaping shall consist of a mix of evergreen and deciduous plantings including living trees, shrubs and ground covers. Plantings of shrubs and ground covers shall be chosen and spaced to result in a covering of the landscape strip within three years. Shrubs shall be of a type that do not exceed a height at maturity of approximately three to four feet. Deciduous trees shall have a minimum trunk diameter of one and three-quarter inches at time of planting, and be spaced so as to result in touching of branches after ten years of normal growth. Evergreen trees shall be a minimum of four feet tall at time of planting and spaced so as to result in a space between trees approximately equal to the mature spread of the trees used. See Figure L-1.

D. Type IV - Open Area Landscaping. Type IV landscaping shall consist of canopy-type deciduous trees or spreading evergreen trees planted in wells or strips, with a mix of living evergreen and deciduous ground covers and low shrubs. Shrubs shall be of a type that do not exceed a eight at maturity of approximately three to four feet. Planting wells or strips shall be a minimum of thirty-two (32) square feet in area, with the narrowest dimension not less than four feet. Deciduous trees shall have a minimum trunk diameter of one and three quarter inches at time of planting. Evergreen trees shall be a minimum of four feet tall at time of planting. See Figure L-1.

Type I. A visual screen with plantings chosen and spaced to grow together within three years sufficient to obscure sight through the screen.

Type II. A visual buffer to effectively screen views at eye level within three years. Trees are to be spaced so that branches touch within ten years.

Type III. A see-through buffer which permits relatively unobstructed views while providing benefits of landscaping.

Type IV. Open area landscaping, typically used in parking lots to provide shading and relief from paved areas.
