4. Mitigation Monitoring and Reporting Program San Leandro Treatment Wetland IS/MND 4-5 February 2024 Implementation Procedure Monitoring and Reporting Actions Monitoring Responsibility Monitoring Schedule that buffer zones will be avoided during construction. Contractor implements measures in the program. City documents that measures are being implemented City’s construction manager During construction Mitigation Measure BIO-4: Exclusionary Fencing and other Avoidance Measures • Prior to initiation of construction activity, 48-inch silt exclusion fencing shall be installed by hand along the southern edge of the access road running on top of the levee between the basin and San Francisco Bay, as well as on either side of the access road where it crosses the culvert between the basin and the solar array. The purpose of the fencing is to protect habitat within the tidal channel from earthmoving activities or accidental spills, and to exclude workers from the channel. • Construction efforts involving the concrete vault box and outfall leading to the tidal slough shall occur during low tide to avoid the potential for turbidity impacts on potentially present special-status fish species. • To minimize turbidity impacts to special-status fish species that could be present in the tidal slough during startup and initial discharge of tertiary-treated effluent, a drainpipe sleeve or similar filtering device shall be installed at discharge point of the outfall structure until turbidity levels stabilize. • Prior to construction, all construction workers shall take part in a worker environmental awareness program conducted by a qualified biologist. The awareness program will be conducted at the start of construction and thereafter as required for new construction personnel. Personnel shall be instructed to avoid areas beyond the exclusionary fencing and any other precautions intended to ensure avoidance pursuant to Mitigation Measure BIO-1 through BIO-3. • Vehicle speed limits on the Project site shall not exceed 10 miles per hour. Implementation Procedure Monitoring and Reporting Actions Monitoring Responsibility Monitoring Schedule City shall contract with a qualified biologist to mark and install exclusionary fencing along all tidal channels within the Proposed Project site.
