§ 155.149 VEHICULAR USE AREA PERIMETER PLANTING.
   (A)   The equivalent of one large (Type A) tree per 50 linear feet of boundary (or fraction thereof) shall be provided in all VUA perimeter landscape buffer areas. Tree requirements may be deferred, if an equivalent number of street trees are present in the right-of-way, until such time that the street trees are removed to allow for roadway widening or other improvements. Additional landscape requirements shall vary relative to adjacent land uses and proximity to common property lines as follows:
 
Distance From Property Line
Land Use
Less than or equal to 30 feet
Greater than 30 feet and less than 50 feet
Greater than or equal to 50 feet
VUA (except loading area) adjacent to any residential use
6-foot continuous screen
3-foot continuous screen
3-foot screen for at least 50% of VUA
VUA is a loading area adjacent to any residential use
8-foot continuous screen
6-foot continuous screen
6-foot continuous screen if adjacent to residential
VUA adjacent to a ROW
3-foot continuous screen
3-foot continuous screen
N/A
 
   (B)   The three-foot or six-foot screen requirement can be met using shrubs, evergreen trees, berms, or fencing individually or in combination. Continuous screens may be broken and staggered for visual interest; provided the result is a visually continuous screen. The three-foot screen requirement may be reduced to 18 inches when adjacent to financial institutions, nursing homes, or other uses where security is determined to be a factor.
   (C)   All screening material including plants, fencing, walls, and berms used to satisfy these requirements shall conform to the standards found in §§ 155.165 through 155.179.
   (D)   Landscape material in buffer areas shall be protected by the use of curbs, wheel stops, fencing, or planted at least four feet from the edge of pavement when sufficient buffer area exists.
