Figure 3-5. Alternative C
Chapter 3 One proposal that would likely be evaluated as part of this step-down planning process is the pumping of sediment of appropriate grain size and nutrient content over a portion of the marsh (refer to Figure 3-4) to raise the elevation of the marsh plain in response to subsidence and sea level rise. Enough sediment would be distributed over the existing vegetation to provide for a slight increase in the elevation of the marsh plain, while still enabling the vegetation to grow up through the added sediment. Pre- and post-project monitoring would be conducted to identify any changes in cordgrass height and vitality, clapper rail use of the area for foraging, and clapper rail use of the area for nesting, as well as other factors. 4. Removal of the Drop Tower Under this alternative, the drop tower located at the end of 7 th Street would be removed and the area currently occupied by the tower would be restored to wetland/upland transition and native upland habitats, as described below. Removal of the tower would eliminate a significant perching site for raptors and great blue herons, which have been documented preying on light-footed clapper rail and/or California least tern adults, chicks, and/or eggs. 5. Habitat Restoration As described under Alternative B, there are several opportunities for habitat restoration on the approximately 37 acres of disturbed upland habitat located within the Refuge boundary. These same areas would be restored under Alternative C, as illustrated in Figure 3-5, but the habitat proposals for these areas would provide a greater mix of upland and wetland/upland transition habitat than is proposed in Alternative B. The rational for emphasizing these higher elevation habitats in this alternative is to address issues related to sea level rise. Much of the Refuge already supports low elevation salt marsh habitat, with relatively few areas available on the Refuge as high tide refugia for clapper rails and other marsh-dependent avian species. To ensure some areas of upland and upland/wetland transition at the edges of the marsh in the future, not all of the area available for wetland restoration would be used for that purpose under this alternative. The acres of each proposed habitat type per restoration site are provided in Table 3-5. The Case Road Pond site and the area to the southeast of 7 th Street Pond would be restored to a range of habitats including intertidal mudflat, salt marsh, wetland/upland transitional, and coastal sage scrub. The intertidal habitats (i.e., mudflat, salt marsh) would include meandering shallow subtidal channels with gentle side slopes to provide a diversity of microhabitats. A disturbed strip of land to the west of 7 th Street, an area at the southwestern end of the 7 th Street Pond, and a portion of the area around the existing drop tower would be restored to wetland/upland transitional habitat. The area located to the east of the drop tower would be restored to salt pan habitat, and as discussed in Alternative B, the inactive monitoring wells in the vicinity of 7 th Street and the bunkers to the west of 7 th Street Pond would be removed prior to restoration. These restoration proposals could be implemented under one project proposal, or the restoration could be phased over a number of years. The extent and timing of when various restoration proposals are implemented would be dependent upon the level of funding that is secured to implement restoration. The overall cost of implementing the restoration proposals would be lower if all of the sites could be restored as part of single project, but this option may not be feasible based on the limited availability of funding sources for restoration. 3-36 Seal Beach National Wildlife Refuge
