<br />3. Bufferyards. This section are intended to be mmImum <br />requirements to achieve screening between differing uses with <br />varied intensities and impacts that are not always complementary <br />when adjacent to one another. When a bufferyard is required <br />under this section, the yard space and planting requirements are <br />not to be reduced for other purposes such as future parking and <br />driveways, building expansions, or other activities that are not in <br />keeping with the purposes of buffering and screening. <br /> <br />a. Bufferyards are intended to provide additional screening of <br />businesses that are adjacent to residential areas. The <br />following table details the width of the bufferyard along the <br />common adjacent property line. An additional increase of <br />landscape plantings would be required in the bufferyard. <br />That increase is expressed in the table below as a <br />percentage of the total required site landscaping. <br /> <br /> Existing Ad.iacent Development <br /> R-1 R-2 R-3 <br /> - B-1 <br /> = Bufferyard width 40ft 30ft 20ft <br />"0 Q,) <br />Q,) e % Increase in plantings 25% 20% 20% <br />I:I.l <br />0 Q.. required . <br />Q.. 0 <br />0 - <br />Q,) B-2 <br />;.. > <br />~ Q,) Bufferyard width 50 ft 40 ft 30 ft <br /> ~ % Increase in plantings 30% 25% 20% <br /> required <br /> <br />b. As an alternative method for screening, fences that <br />are 100 percent opaque may be used to mitigate the impacts <br />of businesses that are adjacent to residential areas. Fences <br />shall be subject to the provisions found in Section 9.11.17. <br />When a fence is used for screening purposes, the bufferyard <br />planting requirements may be reduced by 10 percent from <br />the stated minimum requirement. <br /> <br />o. Grading. <br /> <br />1. Final slope grades shall not exceed 3.5: 1 unless terracing of <br />retaining walls is approved. <br /> <br />2. Berming for parking lots and open space areas shall not exceed <br />3:1. <br />
