Administrative Draft Environmental Impact Report Gill Medical Center Project ■ Restrict working areas, spoils and equipment storage and other project activities to areas outside of the proposed northern buffer area. ■ Maintain water quality and limit construction runoff into the irrigation ditch through best-management-practices (Per Mitigation Measure 4.6-1e). ■ A preconstruction survey for giant garter snake shall occur prior to construction activities and within 24 hours of ground disturbance. Timing/Implementation: Prior to ground disturbance within 200 feet of the Woodbridge Irrigation District canal, Mon itoring/Enforcement.• County of San Joaquin Planning/Development Services Division 4.6-1g: Conduct Preconstruction Surveys for Nesting Migratory Birds and Raptors. The Project Area supports suitable nesting habitat for a variety of special-status birds and birds protected under the MBTA.To minimize impacts to protected bird and active nests during construction, the following measures are required: ■ Conduct a pre-construction nesting raptor and bird survey of all suitable habitat on the Project site within 14 days of the commencement ground disturbance (e.g., tree/vegetation removal, mass grading) during the nesting season (February 1 — August 31).Where accessible, surveys shall also be conducted within 100 feet of the Project site. ■ If active nests are found, a no-disturbance buffer around the nest shall be established. Per the SJMSCP, a 100-foot buffer shall be established and maintained during the nesting season for white-tailed kite, Cooper's hawk, loggerhead shrike, yellow-billed magpie, and other birds protected under the MBTA. ■ The buffer shall be maintained until the fledglings are capable of flight and become independent of the nest, to be determined by a qualified biologist. Once the young are independent of the nest, no further measures are necessary. In addition to the above, the following SJMSCP Incidental Take Minimization Measure shall be implemented should a known Swainson's hawk nest tree (i.e., trees that hawks are known to have nested in within the past three years or trees, such as large oaks, which the hawks prefer for nesting) become occupied by a Swainson's hawk during construction activities: ■ If a nest tree becomes occupied during construction activities, then all construction activities shall remain a distance of two times the dripline of the tree, as measured from the nest. ■ If the Applicant elects to remove a nest tree, the nest trees may be removed between September 1 and February 15,when the nests are unoccupied.
