<br />6.2A <br />Page 23 <br /> <br />The potential for saltmarsh wandering shrew, a State species of special concern, to be present is <br />high because suitable habitat is found in proximity to the Ravenswood Valve Lot and on <br />adjoining lands. Construction-related activities could result in potentially significant impacts if <br />these activities directly affect saltmarsh wandering shrew individuals or their habitat. The study <br />area adjacent to the Ravenswood Valve Lot contains a total of9.8 acres of suitable saltmarsh <br />wandering shrew habitat. Direct permanent impacts on suitable breeding habitat would be <br />limited to the construction of an energy dissipation structure for a discharge pipe, totaling 51 <br />square feet, from which treated potable water would be occasionally released during Project <br />construction and operation. Temporary impacts on suitable breeding habitat also associated with <br />construction of the discharge pipe and dissipater would total approximately 0.07 acre (3,149 <br />square feet). <br /> <br />. Mitigation Measure BID 10: Mitigation Measures BID 1a through BIO Id, which <br />address impacts on salt marsh harvest mouse, would equally address potential impacts on <br />the saltmarsh wandering shrew <br /> <br />Impact BIO -11: Impacts 011 dusky-footed woodrat and destruction of wood rat middens. <br /> <br />The presence of San Francisco dusky-footed woodrat was confirmed during reconnaissan.ce <br />surveys in the coast live oak woodland within the right of way in the alignment's western <br />segment between Cordilleras Creek and the Pulgas Tunnel Portal. Potentially significant impacts <br />on San Francisco dusky-footed woodrat would result from grading and construction in this area, <br />which would likely destroy woodrat nliddens and could result in direct impacts, such as direct <br />mortality of this subspecies. <br /> <br />. Mitigation Measure BID 11 a: Brush and dense grass clearing; hand-disassemble <br />middens; mow and clear brush and herbaceous plants <br />. Mitigation Measure BID 11 b: Survey for woodrat middens <br />. Mitigation Measure BID 11 c: Install orange barrier fencing; hand-disassemble middens <br />. Mitigation Measure BID 11 d: Trap and relocate woodrats in consultation with CDFG <br /> <br />Impact BIO -12: Impacts on white-tailed kite. <br /> <br />Project construction could result in direct impacts on the State-listed fully protected white tailed <br />kite wherever suitable nesting trees are present within the proposed Project alignment or in the <br />immediate vicinity. Significant impacts on this species could include disruption of active nests <br />by pruning or tree removal, or nest abandonment as a result of construction activities. <br /> <br />.

Potential in1pacts on migratory birds <br />include the destruction of eggs or occupied nests, direct mortalities of young, and the <br />abandonment of nests with eggs or young birds prior to fledging. Potentially significant impacts <br />would result from Project construction activities that would destroy occupied nests or cause <br />migratory birds to abandon their nests. <br /> <br />.
