Geosyntecl�' consultants Table F1 EIR Mitigation Measures for Remediation Activities Resource Measure Topic Summary Mitigation Measure Biological MM-BIO-1: Obtain For western pond turtle,alternatives to SJMSCP coverage will include establishing a buffer area of 300 feet between any Resources Coverage under the nesting turtle sites and the waters located near the nesting site.These buffers shall be indicated by temporary fencing if SJMSCP or construction has or will begin before nesting periods are ended(the period from egg laying to emergence of hatchlings is Implement normally April to November). Protective Measures For giant garter snake,alternatives to SJMSCP coverage will include limiting construction activities that may disturb for Nesting Birds, potential giant garter snake habitat to between May 1 and September 30 to the extent practicable.If construction activities Western Pond are necessary in giant garter snake habitat between October 1 and April 30,a qualified biologist would conduct a survey Turtle,Giant Garter within 24 hours prior to construction and monitor construction activities to ensure that individuals of giant garter snake Snake,and Valley encountered during construction are avoided.If a giant garter snake is encountered during construction activities,the Elderberry biologist will have the authority to stop construction activities until appropriate corrective measures are completed or it is Longhorn Beetle. determined that the snake will not be harmed. Giant garter snakes encountered during construction activities will be allowed to move away from the construction area on their own.If giant garter snakes are observed in burrows or other wintering habitat,burrows will be flagged,and a 200-foot buffer will be established and maintained until the biologist confirms that snakes are no longer present. The project area will be reinspected by the biologist whenever a lapse in construction activity of 2 weeks or more has occurred. For valley elderberry longhorn beetle,alternatives to SJMSCP coverage will include conducting a survey of the project site to confirm the presence of any elderberry shrubs.If elderberry shrubs are identified on the project site and cannot be avoided,TC NO. CAL.Development will coordinate a removal and replanting effort with CDFW. Biological MM-BIO-2: Obtain A NPDES Construction Stormwater General Permit will be obtained for the proposed project,which will require the Resources and Implement development of a construction Stormwater Pollution Prevention Plan(SWPPP). The construction SWPPP would include NPDES BMPs including or similar to use of barriers(e.g.,netting or sandbags)to prevent pollutants from entering drainage Construction channels,equipment inspection for spills,and maintenance and implementation of material spill prevention and cleanup Stormwater General plans.The construction SWPPP would ensure that contaminants are not accidentally introduced into the drainage Permit. channels. Biological MM-BIO-3:Tree TC NO. CAL.Development will plant a minimum of 30 trees,including Patmore ash(Fraxinus p. 'Patmore),Chinese Resources Replanting. pistache(Pistachia chinensis),coast redwood(Sequoia sempervirens),and multi-trunk chaste tree(Vitex agnus-castus), on the project Warehouse Development Area in locations where future removal is not likely to be required.
