Wildl'de species observed during the field investigations included: American robin, winter wren, rufous-sided towhee, black capped chickadee, downy woodpecker, blacktail deer(tracks), Douglas squirrel, red-legged frog, tree frog, and mountain � beaver(carcass)• The number of wildlife species that utilize the site could be expected to be much higher than the number actually observed during our limited � field investigation due to the seasonality and secretive nature of most wildlife ' species. 7.0 SUMMARY OF EXISTING CONDITIONS � The wetland/stream inventory and delineation on the 14.4-acre site revealed that there are two wetl3n�s and one stream on the site. Cunently, most of the site is �� covered with mixed coniferous/deciduous uptand forests. Merrill and Ring Creek ` and its associated wetland form the largest environmental restraint on the site with a 50-foot wide buffe�required along the stream and a 75-foot wide buffer along the wetland. There is also a small wetland in the northwest comer��f the site that will require a 50-foot wide buffer. Narbeck Creek runs immediately west of the site and will require a 25-foot wide buffer. The locations of the wetlands and streams near the edges of the site, however, allow for substantial developme�t on the site. 8.0 PROPOSED PROJECT ... 8.1 Description The proposed project is a 205-unit, multi-family residential development with � associated parking and intemal road system (Figure 5). Access to the development would be from Merrili Creek Parkway. G+� 8.2 Development Impscts on Wetlaad Bufters No direct impacts on wetlands will result from development of the proposed project. Stormwater will be detained in underground vaults located in the developed portion of the site. A wetpond will be located in the southeastem comer of the site to provide water quality treatment of the previously detained stormwater. Effluent from the wetpond is proposed for direct discharge into Merrill and Ring Creek at the existing concrete structure associated with the culveR beneath Merrill Creek Parkway. Direct discharge into the structure will result in both enhanced aPration a�d prevention of streambank instability. The standard buffer for Wetland B, which is associated with Merrill and Ring Creek, is 75 feet. To construct the wetpond, a small area of wetland buffer will be disturbed by grading, but the area will be landscaped following wetpond construction. Restoration for this buffer disturbance is outlined in Section 8.3. The wetland buffers in the northwestern portion of the site are not proposed for reduction. 8,3 Wetland Buffer Restoration(Drawiog W-1) Encroachment into the area affected by construction of the wetpond will be restored through installation of native trees, shrubs, and emergents plantings, incorporation of large woaiy material (i.e., stumps, down logs, and brush piles), and removal of Wetland and SVaam Study RepoA T�usaw Co�w+Rmb Mertill Cra�k Ap�rtrMnb 6 �OQrwtl.ryt February 20,199E �
