Soil Investigations for Data Collection in the Delta Initial Study/Proposed Mitigated Negative Declaration 129 Therefore, the Proposed Project is not expected to have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies or regulations or by CDFW or the USFWS. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? No impact. The Proposed Project would not have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act because the Proposed Project would not subject wetlands to filling, removal, hydrological interruption or other means. Previously verified pre-jurisdictional determinations will be utilized during mapping and field visits to ensure that the Proposed Project would avoid any areas that, as determined by a wetland specialist, may require a Wetland Delineation. While there would be no impact to federally protected wetlands, implementation of Mitigation Measures MM BIO-1b and MM BIO-12 would further avoid, minimize and/or reduce the potential for impacts. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Less than Significant with Mitigation Incorporated. The Proposed Project would not be expected to substantially interfere with the movement of any native or resident fish species, because the activities conducted overwater would be isolated in area and duration, and would not block, alter or degrade any of the waterways that these species are using for movement or migrations. Implementation of Mitigation Measure MM HYD-1 would reduce potential impacts to water quality to Less than Significant with Mitigation Incorporated (see Section 3.10, Hydrology and Water Quality). Additionally, implementation of Mitigation Measure MM BIO-14 would limit overwater work to only within the appropriate fish work window (August 1-October 31) when sensitive life stages of migratory fish would be less likely to occur in the Study Area. The Proposed Project would not be expected to substantially interfere with established native resident or migratory corridors or interfere with the use of wildlife nursery sites, because of the limited duration and scope of each Impact Area. Additionally, the implementation of Mitigation Measures MM AES-2 and MM BIO-1 would ensure that migrating animals do not become entrapped or harmed and that no work be conducted outside of daylight hours and no artificial light sources, which could disturb nocturnal wildlife, would be used.
