Order#13273, Corps Reference#1VWS-2013-1077 • Smith Island Terminal,LLC May 4, 2016 Page 2 of 18 • Area 1: Create 2.4 acres of freshwater wetland habitat immediately north of the Cedar Grove composting facility. This mitigation area was installed in 2004. • Area 2: Restore the heavily degraded upland habitat adjacent to the blind slough to approximately 5.7 acres of intertidal habitat, and convert approximately 2.9 acres of palustrine wetland and the blind slough into intertidal habitat. This includes removal of an existing tidegate, setting back the existing levee approximately 250 feet, and installation of a self-regulating two-way tide gate in the setback levee. • Area 3: Excavate disturbed upland areas to create an additional 1.8 acres of estuarine habitat. Wetland conversion in this area will be 0.04 acre. This includes removal of 100 linear feet of the existing levee, excavation of tidal channels, and construction of a new setback levee that connects to the Area 2 self-regulating two-way tide gate. • Area 4: Remove approximately 550 linear feet of the levee adjacent to Union Slough and create intertidal habitat in 6.15 acres of the mitigation area. Wetland conversion in this area will be 1.36 acres. This includes construction of a new setback levee, a pedestrian bridge, and a public parking area. • Establish and enhance upland buffers around the wetland mitigation areas, including preservation of approximately 11.6 acres of tidelands and removal of at least 20 creosote- treated wooden piles from the tidelands. The project is located at 36th Place NE, Everett, Snohomish County, Washington, Wetlands, Lower Snohomish River Estuary, Section 5, T. 29 N., R. 5E., WRIA 7.
