Significance After Mitigation: Less than Significant Finding: Changes have been incorporated into the Project that would avoid the significant environmental effect as identified in the Revised Final SEIR. Mitigation Measures 4.E-2 through 4.E-4, which have been incorporated into the Project, will reduce the significant environmental impact to a less than significant level. Facts in Support of Finding: The following facts and mitigation measures indicate that the impact will be reduced to less than significant. 1. Construction activities within the Project- specifically, reconstruction and widening of the freeway on-ramp bridge over the Alamo Canal - could affect wetlands and wetland habitat. 2. Implementation of Mitigation Measures 4.E-2 through 4.E-4 set forth in Table 5-1 of the Final SEIR and listed in the RMMRP will ensure that Impact 4.E-lc will be reduced to a less than significant level and are hereby incorporated by reference and described below. Mitigation Measure 4.E-2: Wetland Delineation. In coordination with the City, a qualified wetland ecologist shall conduct a wetland delineation of the proposed bridge expansion and replacement site to identify potential waters of the United States (U.S.) (including wetlands) or waters of the state which may be present. If no waters of the U.S. or waters of the state are identified onsite, no further action is required. Should waters of the U.S. or waters of the state be determined present within the site, features shall be mapped and documented in a report for submission to the appropriate jurisdictional agencies retaining authority over the identified features. Site(s) affected: Proposed bridge expansion and replacement site. Mitigation Measure 4.E-3: Wetland Avoidance and Protection. Access roads, work areas, and infrastructure shall be sited to avoid and minimize direct and indirect impacts to wetlands and waters. Where work will occur within and/or adjacent to federal and state jurisdictional wetlands and waters,protection measures shall be applied to minimize the footprint of overall impacts and protect these features. These measures shall include the following: • A protective barrier(such as silt fencing) shall be erected around the work area(s)to minimize disturbance to wetland or water features and isolate adjacent to wetland or water features from construction activities to reduce the potential for incidental fill,erosion, or other disturbance beyond what is necessary for bridge expansion and replacement;
