1 d. Parking lot landscaping. All parking lots are required to provide internal and/or <br /> 2 adjacent overstory tree plantings in an effort to shade parking surfaces and provide <br /> 3 visual relief. The planting schedule is established to provide an acceptable number of <br /> 4 plantings that may be planted in regular symmetrical patterns or irregular clusters or <br /> 5 groupings. Plantings are required at the following minimum schedule and are credited <br /> 6 toward the minimum planting requirements for the district: <br /> 7 1. 1 tree per every ten parking spaces. <br /> 8 2. Every overstory tree planting shall be provided with a planting area of at least <br /> 9 162 square feet (equivalent of a 9 foot x 18 foot parking stall). <br /> 10 3. Acceptable ground cover materials include sod, mulch, and other natural ground <br /> 11 cover. Landscaping rock and plastic underlayment is prohibited in planting <br /> 12 islands. <br /> 13 e. Bufferyards. Bufferyards help to achieve screening between differing uses with varied <br /> 14 intensities and impacts that are not always complementary when adjacent to one <br /> 15 another. When a bufferyard is required, the yard space and planting requirements are <br /> 16 not to be reduced for other purposes such as future parking and driveways, building <br /> 17 expansions, or other activities that are not in keeping with the purposes of buffering <br /> 18 and screening. <br /> 19 1. Bufferyards are intended to provide additional screening of businesses that are <br /> 20 adjacent to residential areas. The following table details the width of the <br /> 21 bufferyard along the common adjacent property line. An additional increase of <br /> 22 landscape plantings is required in the bufferyard. The table below outlines the <br /> 23 minimum required additional plantings, expressed as a percentage of the total <br /> 24 required site landscaping(the percentage is applied to the total number of trees <br /> 25 and shrubs for the proposed development): <br /> 26 <br /> Proposed Development Existing Adjacent Development <br /> RR, MR, R-1 A, R-1 B, R- R-2 R-3 <br /> 1C <br /> Business (B-1, B-2, B-3) 40 feet 40 feet 40 feet <br /> Buffer and width <br /> % increase in plantings 3 0% 3 0% 3 0% <br /> Industrial(I-1, I-2) 60 feet 60 feet 60 feet <br /> % increase in plantings 3 0% 3 0% 3 0% <br /> 27 <br /> 28 2. As an alternative method for screening within the bufferyard, fences that are 100 <br /> 29 percent opaque may be used to mitigate the impacts of businesses that are <br /> 30 adjacent to residential areas. When a fence is used for screening purposes, the <br /> 31 bufferyard planting requirements may be reduced by fifty percent from the stated <br /> 32 minimum requirement. <br /> 33 f. Credit for preservation or establishment of native grasses and plant communities. The <br /> 34 total number of required trees may be offset by the provision of native grasses and <br /> 35 wildflowers. Establishment or preservation of native plant communities can reduce the <br /> 36 required number of tree plantings by one tree per 500 square feet of native grass/plant <br /> 37 community area. Credit may not exceed 50 percent of the total requirements. <br /> 38 1. This area(s) must be shown on both the landscape plan and the grading plan. <br /> 39 2. Species, quantities, and application method and rates, shall all be provided as part <br /> 40 of the landscape plan. <br /> Page 76 of 141 <br />
