In addition to restoring Walton Creek through Wetland C, the Public Amenities Master Plan proposes to <br /> implement additional habitat enhancements in the wetland to restore tidal influence within portions of <br /> the wetland and to enhance long-disturbed areas of the wetland complex that exhibit low diversity and <br /> limited habitat opportunities. The enhancement work will include the removal of some of the larger <br /> beaver darns within the Wetland C complex and the excavation of several narrow, shallow channels <br /> throughout the wetland. (Ongoing maintenance will be required to keep beavers from re-establishing <br /> their darns.) These channels will connect to the Snohomish River at several locations, providing <br /> additional opportunities for increased tidal exchange within the wetland. Excavated materials will be <br /> used to build hummocks adjacent to the channels, and these hummocks will be vegetated with scrub- <br /> shrub or forested wetland plantings. Large woody debris will be installed along the channels to increase <br /> habitat quality. <br /> — — -- --......-7.--_-_-_-.---.--- — — <br /> Fri �..z_ - _ _ Tac+YiC,��--�P"'� - <br /> ,... �, r i f <br /> : <br /> I <br /> ' .... yg :4',Wiz- <br /> ! _ ,1 471, <br /> Iiia eNt 1 .`t <br /> t <br /> aliktt <br /> - { A'�.
