2 Er�uiron�nentalAraalyr�r <br /> observed within or adjacent to the proposed project area. Hawever, four previous <br /> documented occurrences of CLT nesting sites in the vicinity of the project were reported <br /> in 1970. The closest reported occurrence of CLT nesting sites was on Bair�sland. The <br /> CLT is considered likely to occur withiti the pxoject a�ea. <br /> • Alameda song sparrow{Medospa�a melodiapusilluda). The Alameda song sparrow is listed as <br /> a speciaZ-status species. Coastal salt marsh foun.d along channels and creeks is theix <br /> primary hahitat Five occuxrences of the Alameda song sparrow have been documented <br /> within a five-mile radius of the project area. The most recent occurrence was in 2004 on <br /> Bair Island. No AZameda song sparrows were observed during the site assessment. The <br /> presence of suitable narth coast salt marsh habitat within Redwood Cteek suggests that <br /> Alameda song sparrow may occur within or near the project area. <br /> • Western snowy plover(Charad�ius alexandrines rivo,ra�s}. The western snowy plover (W5P) is <br /> listed as threatened by the USFWS. No suitable habitat was found during the site <br /> assessment within or adjacent to the proposed project area. No other occurrences of <br /> WSP within or adjacent to the proposed project area were documented. The WSP has a <br /> low potenrial to occur within the project area. <br /> • Sa1t marsh common yellowtl�roat (Geoth�i,r trichas sinuo.ra). The salt ma�sh common <br /> yellowthroat is a non-migratory bird that is a state-listed special-status species. The <br /> optimal habitat fox the salt marsh common ye]].owthroat includes dense woody <br /> vegetation. Salt marsh common yellowt�iroat was not observed during the site assessment, <br /> and no occurrences of have been documented within a five-mile radius of the project <br /> area. However, due to the presence of suitable habitat in areas adjacent to the project <br /> area, the salt marsh common yellowth.raat ma�T occur within or near the project area. <br /> • Salt marsh wandering shrew (Sorex vagrans halicoetes). The salt marsh wandexing shtew <br /> {SMWS) is a state-listed species of special concern. One occur�ence within a�ive-mile <br /> radius of tl�e project area was documented in 1985. The SMWS was not observed during <br /> the site assessment. Hawever, suitable habitat is adjacent to the project,and the SMWS <br /> may occux within or near the project area. <br /> • Sa1t-marsh harvest mause {Keathrodontomys raviventras). The salt-marsh harvest mouse <br /> {SMHN� is listed as a federailp and state endangered species. T�e SMHM is confined to <br /> salty marsh habitat urithin the San Francisco Bay estuaries. SMHM depend heavily on. <br /> dense vegetation,especially pickl.eweed,within nnarsh-like Y�abitat. No SMHM were <br /> observed duting the site assessment However, due to presence of suitable habitat ia <br /> areas adjacent to the project,the SMHM may occur in the project area. <br /> Speclal Status PlaritSpecies arld Communities. The reconnaissance levels survey for special- <br /> status species and endangered plants included searching of the California Native Plant Sociery <br /> (CNPS),the USFWS,and the CDFW databases. Based on suitable habitat in the p�oject area, three <br /> special-status plant species were identified as having potential to occur in the area. These include the <br /> species listed below: <br /> 2-16 US 101 Pedestraa�a Underct�ssirag arrd Bair <br /> Island Koad Starrr� Draira Prrrrsp Station ProjeL�t <br />
