7.B. - Page 60 2 Environmental Analysis Mitigation Measure BIO 1: Construction Scheduling The contractor shall install a temporary cofferdam during low tide to reduce impacts to water quality and aquatic species. The Contractor shall schedule other construction actions to avoid effects to listed species and habitats,to the extent practical. Mitigation Measure BIO 2: Pre-Construction Surveys and Buffers The City shall have a qualified biologist conduct pre-construction surveys for any endangered, special-status plant and animal species or migratory birds 72 hours prior to the commencement of pump station construction and again prior to the commencement of construction of the US 101 undercrossing project. If any migratory bird nests are detected, the City shall establish a buffer around the nest unless the California Department of Fish and Wildlife (CDFW) approves alternative measures. Typically a 50-foot buffer shall be set around any passerine/or non-passerine nests,and a 250-foot buffer shall be set around any raptor nest. Mitigation Measure BIO 3: Pre-Construction Surveys for Roosting Bats The City shall have a qualified biologist conduct pre-construction surveys for any roosting bats prior to the commencement of any construction activities under or within 100 feet of US 101 and Convention Way bridges. If any roosting bats are found under a bridge or within trees in the project area during pre-construction surveys, the City shall contact the U.S. Fish and Wildlife Service (USFWS) or CDFW to determine how to proceed. Typically,the City shall passively exclude or evict the roost site for two consecutive days. If there is a period without construction activity within 100 feet of the bridges during the bat roosting season, an additional bat pre-construction survey shall be conducted. Mitigation Measure BIO 4: Install Exclusionary Fencing Prior to the onset of construction within 100 feet of Redwood Creek, the Contractor shall install exclusionary fencing around the project area limits to prevent special-status species from entering the project area. During the installation of wildlife exclusionary fencing,a qualified biologist shall monitor the area for any potential presence of endangered or special- status species. In the case an endangered or special-status species is found, the CDFW or USFWS shall be contacted for the appropriate procedures to follow for the protection of the species. Mitigation Measure BIO 5: Employee Education and Awareness Training Prior to construction of the pump station and US 101 undercrossing, a professional biologist shall conduct an educational program for construction personnel. This program shall include the following: • Information on protected species and their habitats that are likely to be found on site; • Federal and state law requirements pertaining to these species; 2-20 US 101 Pedestrian Undercrossing and Bair Island Road Storm Drain Pump Station Project
