.,.., ENVIRONMENTAL CHECKLIST also a recreational trail along the southern shore of the slough. There is no cordgrass in this area adjacent to the Project alignment. None of the marsh areas provide suitable habitat for Califomia clapper rail or Califomia black rail, and lack of a mix of pickleweed and cordgrass, as well as the lack of fully tidal channel networks and mudflats. Therefore, these marshes aze not expected to support rails. The ruderal habitat and non-native grasslands of Oyster Bay Point Regional Park have a low potential to support ground squirrel burrows of suitable size for burrowing owl. Ground squirrels were observed on the flood control levee (Environmental Science Associates, 2004} and numerous burrows were observed at Oyster Bay Regional Park. During construction, impacts to burrowing owl, if present, could occur due to duect mortality from equipment and harassment due to noise or vibration adjacent to burrows. Construction activities near active nesting burrows could result in nest failure and loss of eggs and/or young. Measure B-1 would be implemented for construction within or adjacent to potential burrowing owl habitat. Potential nesting habitat for raptors and other special-status birds is within the marsh at the WPCF, as well as in large trees throughout the Monarch Bay Golf Course Complex. Other than the potential removal of six ornamental trees for the construction of the water recycling plant, no potential nesting habitat would be directly affected by installation of the pipeline. Alameda song sparrow and northern harrier are ground-nesters in salt marshes; white-.tailed kite, American kestrel, red-tailed hawk, and red-shouldered hawk all use large trees, such as the eucalyptus and conifers present on the golf course, for nesting; loggerhead shrike nest in small trees and shrubs, such as those found on the golf courses and along San Leandro Slough; brown pelican nest on islands off the Pacific coast but are found loafing and foraging around the bay and have been observed at San Leandro Slough (Environmental Science Associates, 2004). Indirect disturbance resulting from construction activities could cause nest abandonment and death of young or Iass of reproductive potential at active nests located near the Project routes. Measure B-2 would be implemented during construction adjacent to habitat for nesting raptors and other special-status nesting birds. Implementation of Measures B-1, and B-2, as well as Measures B-3 and WQ-1, would reduce potential impacts to special-status wildlife species to aless-than-significant level. b) Construction activities would not result in the removal or disturbance of riparian habitat since trenchless techniques will be used to cross waterways. No direct impacts to northern coastal salt marsh, the only sensitive natural community within the Project area, would occur as a result of project activities. However, sensitive marsh habitat along the Phase 2 alignment could be impacted by potential accidental releases of construction materials, such as bentonite and/or vehicle and equipment fluids, into the marshes, which could destroy marsh vegetation and impact water quality. Erosion of sediments produced as a result of construction activities could impact sensitive marsh habitat as well. Measure B-3 would be implemented during construction of Phase 2 of the Project. Development of a Storm Water Pollution Prevention Plan (SWPPP), implementation of Best Management Practices (BMPs), and compliance with RWQCB National Pollutant Discharge Elimination System (NPDES) permit requirements would reduce potential impacts associated with sedimentation or pollutant concentrations in storm water runoff originating from construction activities.. In addition, the BMPs required by Measure WQ-1 (see Section VIII, Hydrology and Water Quality) for erosion control would avoid potential erosion and sedimentation to storm drains and/or receiving waters. c) No direct disturbance or fill of wetlands protected by Section 404 of the Clean Water Act would occur as a result of the Project. Direct disturbance of potentially jurisdictional waters including, San Leandro Slough, a drainage channel that carves runoff from the Metropolitan Golf Links, located north of the WPCP would not occur since bore and jack techniques or bridge attachment San Leandro Recycled Water Project 2-1 ~ FSA / 7A3193 Daft IS/MND
