Article XVI is amended by adding a new Section 15-269 to read as follows: 2 . 3 Section 15-269 Buffers in Northern Transition Area 4 5 (a) .The Board finds that: 6 (1} Soil and pollutants carved overland, primarily from roads, trails and land 7 - disturbing activities, can be effectively .trapped by leaving a relatively 8 undisturbed strip of vegetation parallel and adjacent to the watercourse. 9 (2) Properly managed overland water flow can be directed into this buffer in a 10 manner that will reduce velocity and cause dispersion of the water. . 11 (3) Sediments and associated pollutants carried by the water will settle out as a 12 result of this slowing and dispersion process. 13 (b) For purposes of this section, the term "Northern Transition Area" shall mean the 14 Transition Area portion of the Carrboro Joint Development Area as identified in the 15 Joint Planning. Agreement. 16 (c) Development on lots within the Northern Transition Area shall, if any of the 17 watercourses identified below are located in whole or in part within the lots so 18 developed, contain a designated buffer area adjacent to such watercourses. The 19 buffer azea boundaries shall be demarcated by a line connectuxg the points on either 20 ~ side of the watercourse located as follows: 21 22 (1) Bolin Creek and Tributaries (permanent streams flowing into Bolin Creek) 23 as shown on the Northern Transition Area Stream Buffer Map on file in the 24 Carrboro Planning Department, which map is incorporated herein by 25 reference. Measure along a line running perpendicular to the edges of the 26 ~ floodplain (or if no floodplain has been demarcated, the center of the stream) 27 one hundred (100) feet from the edge of the floodplain (or if no floodplain has 28 been demarcated, from the edge of the water) plus an additional. distance 29 equal to 30 31 4 x slope x 100 32 33 where slope is expressed as a percentage derived from dividing by 100 the 34 rise of elevation between the floodplain boundary line (or if no floodplain has 35 been demarcated, the edge of the water) and a point one hundred (100) feet 36 from that point along the perpendicular line described above. 37 (2) Intermittent streams flowing into Bolin Creek and its tributaries as shown 38 on the Northern Transition Area Stream Buffer Map. Measure along a line 39 running perpendicular to and sixty (60) feet from the center of the 40 intermittent stream. - .......» ..............................-.....................-....._.................................._............
