A constructed ditch drains Wetland A to WeUand B. Il was cleared and now has urban runoN and encroachment. Wetland B contains a beaver dam and storm water, and much of the wetland and its buffer o��-site has exporlenced disturbance from development. Wetland C is Isolated, wfth part of its buffer encroached upon �+v development. Watland C is a small watershed that has likely been impacted by stoim water dumping or dralning. This is important, as an uutlet will be installed to cantroi the high level of water from Wetland C, (5) METHODOLOGY The 1987 Federal Methodology was used to delineate the wetlands, along with the 1997 Department of Ecology methodology. (6) CLASSIFICATION OF STREAMS AND WETLANDS All the wotlands are Category III wetlands. The buffers are 25 feet from the wetlands. (7) MITIGATION Mitigation is provided for impacts to tho wetlands. Im�acts to the wetlands include filling in areas A, B, and C, and a paper flll fn area D. Area G in tract 996 will be designated as addltional buf(er. Area H wlll be enhanced. Table 4 shows mitigation ratios with the total of buffer gained and lost coming up with an excess buffer of 12,973 squere feet, Totaling wetland flll and the paper fill, multiplying times 2 at a 2:1 ratlo, we errive af 12,200 square feet. Subtr��cting this from the excess buffer gain we end up with an excess buHer gain of 771 square feot to account for the actual wetland and paper wetland fill. Add this to wetland enhancement of 7,897 square feet; we can mitlgate for the loss of buffer along lot 15, and tract 999, tho storm water tract. In summary, Innovative design is explained in greater detail. The main Intent of Innovative dosign is to maintain aroa G as added buffer, which is a somewhat mature stand of forost. 30A7 BAA, inc. 1/11IOS U
