Unless otherwise expressly stated, the perimeter landscaping standards of this section apply to all of the following in all zoning districts:
1. the construction or installation of new vehicular use areas;
2. the repair, rehabilitation or expansion of existing vehicular use areas, if such repair, rehabilitation or expansion would increase the area of the vehicular use area by more than 20%;
3. existing vehicular use areas that are accessory to an existing principal building if the building or any portion of the building is expanded or enlarged and the expansion increases the existing floor area by more than 50% or 5,000 square feet, whichever is less; and
4. the excavation and reconstruction of existing vehicular use areas if such excavation and reconstruction involves the removal of 50% or more of the asphalt, concrete or other pavement devoted to vehicular use.
88-425-05-B. ADJACENT TO STREETS
When a vehicular use area is located adjacent to a public right-of-way, perimeter landscaping must be provided to provide physical and visual separation between the vehicular use area and the right-of-way. This requirement applies only when there are no intervening buildings between the right-of-way and the vehicular use area. Trees planted to satisfy the street tree planting requirements of 88-425-03 may be counted toward satisfying the tree planting requirements of 88-425-05-B.
1. Perimeter landscaping adjacent to street rights-of-way must be provided in the form of a perimeter landscape buffer strip located between the vehicular use area and the street right-of-way.
2. Except as provided below for vehicular use areas within the downtown loop, the landscape buffer strip must be at least 10 feet in width and be planted with at least one tree per 30 linear feet of landscape strip and enough evergreen shrubs to form a continuous visual screen at least 3 feet in height after the first growing season.
