1�_ ✓ not provide any measures to ensure that the mitigation is successful and fully compensates the losses." • No fill or dredged material would be discharged. Wetlands habitats and waters of the U.S. would experience indirect impact from shading as a result of boardwalk and dock construction. Approximately 0.32-acre of wetland habitat would be shaded as a result of boardwalk construction. Approximately 0.11-acre of waters of the U.S. would be shaded as a result of dock and gangway construction. Compensation for the effects of shading on wetland vegetation is not proposed at this time. Mitigation for shading, if determined to be necessary by USAGE, may include providing spaces between the planks of the docks and walkways to allow light infiltration and elevating the dock and boardwalks high enough to allow light to infiltrate from the sides. Also, the project will participate in the San Joaquin County Multi-Species Habitat Conservation Plan where applicable. In addition,there is ample room to provide on-site mitigation. The project proponents have already had discussions with USFWS and CDFG about providing on-site mitigation. Additionally, a mitigation monitoring program has been generated, designating a corresponding agency, to ensure mitigation is successful. "The cultural resources section in the Initial Study concludes that no resources were located within the area, but Figure 4 of the Biological Resources Report and Evaluation (Jones and Stokes, February 2007) has a mapped archeological site. This mapped resource needs verification/clarification." • On June 30, 2006, and August 17, 2006, archaeological surveys of the area of potential effect (APE) were conducted on Spud Island. Intensive archaeological surveys were conducted by Stacy Schnyeder, M.A., and Daniel M. Gilmour, B.A. All portions of the island accessible by foot were surveyed using pedestrian transect intervals of less than 10 meters. In addition, the APE was intuitively probed using a 4-foot long steel probe in order to test for subsurface remains and to assess the general depositional history of sediments. Areas with dense brush were surveyed using cursory survey techniques. Areas with exposed soil (rodent back dirt and erosion features such as slumps and slides) were examined for cultural remains. Significant portions of the island exist as designated wetlands and marshes. These areas were often inaccessible due to their inundation with water. Such areas were visually examined from boat when possible. No archaeological resources were identified within or immediately adjacent to the project area. A cultural resources report has been prepared for the project and will be sent to USACE with the Department of the Army Permit Application to support the fact that this project complies with Section 106 of the National Historic Preservation Act(NHPA).
