Take Highway SR 20 to U.S. Highway 101 and go west on Highway 101 approximately 7 miles west to 275274 Highway 101. Address 275274 Highway 101 is on the left of the highway nearing the top of the hill just past Birds Unlimited. RECEIVED JAN 12 2018 JEFFERSON COUNTY ,nr,onNmr-TAL HEALTH BUFFER AVERAGING REPORT Wetland 002334003 is located on north side of Highway 101 (Figure 1). The parcel is 661.4 feet Figure l — Site Location wide and 1,951.5 feet long. The parcel landform has a 10 to 15 percent rise to approximately 1,603 feet from the parcel property line near Highway 101 to a slope break were the land slopes downward ranging from 20 to 25 percent approximately 70 to 80 feet to Wetland 002334003. Wetland 002334003 rated out as a Category III Wetland. A Category III Wetland for a moderate impact land use requires a 110 foot buffer when the habitat score occurs from 5-7 points. The 110 foot buffer was measured out and corrected for slope to obtain a horizontal distance (Figure 2 and x Figure 3). The corrected buffer ranges from 20 to 20 z"a* 4 r feet beyond the slope break on to slope ranging from 5 to 10 percent. The buffer north of the slope break consists dominantly of a vegetative cover of pasture grass mix. A few small flower beds of crocus are present with one or two rhododendron. The vegetation on the steeper slopes of the buffer is dominantly dense Rubus spectabilis (salmonberry) with Rubus ursinus (trailing blackberry). Multi stem Acer macrophyllum (big -leaf maple are scattered across the slope as well as Alnus rubra (red alder) and planted sapling Pseudotsuga menziesii (Douglas fir). A single family residence and associated appurtenances (workshop and pole equipment shed) along with an Accessory Dwelling Unit (ADU) planned on the north side of the wetland. The 30'x40' ADU will be at the edge of the wetland boundary while the main residential structure and other associated appurtenances and structures will be farther than 140 feet from the wetland. A tentative site plan is presented on below (Figure 3). The southwest corner of the ADU is presently at the edge of the 110 foot buffer. It is placed this close to the buffer edge to allow for best view advantages for the ADU and the primary single family residence. To allow the ADU to have some back yard the buffer will be averaged between the ADU and the slope break. As shown, in Figure 3 below, the buffer will be reduced 856 square feet south of the ADU. Eight hundred fifty six feet (856 ft.) will added on the north side of the buffer boundary immediately east of the reduced buffer area. The buffer averaging does not reduce the total buffer average to less than would be contained within the prescribed buffer. The minimum reduced buffer width in not less than the 75 percent of the standard prescribed buffer width. As stated in the above paragraph the expanded buffer will be immediately east of the reduced buffer and will continue to be parallel to the wetland boundary and does not create any panhandles. As far as known the buffer has never been reduced in accordance with subsection (5) of Subsection 18.22330 and the buffer has never been reduced before as Wetland 002334003 has never been delineated, classified or ranked before nor has a buffer been applied until now.
