8.A. - Page 28 verification process, the USACOE will determine which wetlands on site are regulated by them. Mitigation Measure Biology -8: The applicant shall obtain all necessary permits pertaining to affected Waters of the United States regulated by the U.S. Army Corps of Engineers, California Department of Fish and Game, and San Francisco Bay Regional Water Quality Control Board. Discharge of fill into Waters of the United States will require a Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers and Clean Water Act Section 401 certification from the San Francisco Bay Regional Water Quality Control Board. The applicant shall comply with all conditions in the approved permits at all times. The permitting process will likely require compensation for impacts to wetlands. Compensation could include purchase of mitigation credits for the affected habitat types at an established mitigation bank, preservation and enhancement of in-kind habitat types, or creation and preservation of in-kind habitat types. Mitigation Measure Biology -9: A temporary cofferdam shall be installed upstream of the work area if the drainage is flowing during road grading, culvert installation, or any construction activity involving the drainage. Water shall be diverted through a temporary pipe around the work area and routed back into the drainage downstream of the work area. If necessary, a pump may be utilized to help displace the water. The cofferdam, pipe, and pump would be removed after work is completed and the drainage would be returned to its original condition. Mitigation Measure Biology -10: A Best Management Practices (BMPs) Plan shall be developed and put in place prior to the initiation of project activities. The BMP Plan shall be submitted for the review and approval by City staff prior to the issuance of any permits for the construction of Phase I of the project. The BMPs shall include silt fencing and/or straw bale barriers to be placed as necessary along the edge of construction activities leading to the drainage area to prevent particle laden runoff and wet soil sloughing from occurring outside of the construction area. Disturbed soils shall be re -vegetated as soon as possible with grass or other appropriate native vegetation. Re -vegetation shall be performed in a timely manner to avoid soil erosion from rain or wind. The applicant shall implement the approved BMP Plan. Mitigation Measure Biology -11: The CC&Rs shall outline and require the implementation of a periodic cleanup plan for removal of any debris buildup or trash that may obstruct natural drainage flows, destroy or harm any natural habitat, or visually mar the proposed project area. Finding: Implementation of Mitigation Measures Biology -7, Biology -8, Biology -9, and Biology -10 would reduce construction impacts to wetlands and drainage to a less - than -significant level. Implementation of Mitigation Measure Biology -11 would reduce post - construction impacts to wetlands and drainage to a less -than -significant level. 12
