Z Environrnentr�l Analysi,r review of the historical range of the species, suitable habitat in the action;irea,and the absence af baxriers that would prevent passage of these species into or through the ar�a (see Appendix D for a discussion af the selectian criteria). The site assessment conducted for t�e BRS found no evidence of any of these endangered and special status species in the project area. � Central Ca.lifamia coast steelhead (Oncorby�achars myk,i.rs aridieus). The central California coast steelhead (CCC) has been federally listed as threatened. Critical habitat for CCC includes estuarine waters. Wildlife corridors are xautes that animals regularly and predictablp follow during seasonal migration,dispersal from native ranges,daily travel within home ranges,and inter-population movements. While CCC could forage or rest in the area,Redwood Creek is not classified as spawning habitat.:�survey was conducted along Redwood creek in August 1981 as part of a fish distriburion study for the presence of steelhead trout. Neithex the north branch nor the sauth branch site contained steelhead (Leidp 2005). The CCC was not observed during the site assessment and has a low potential of occurring within the project area. + Green sturgeon (.�cipensermedirostris}. The green sturgeon {GS) is listed as federally threatened by tl�e NMFS. GS are commorily found in estuarine areas throughout the San Francisco Bay and are considered year round residents within the 5an Francisco Bay. The areas below the ordinary kugh water mark,including Redwood Cxeek,axe designated as critical habitat. GS would+�-Eia ate in and out of the area with the tides. Biologists determined that the likelihood for GS to occur within.the immediate vicinitp of the project is low. • Tidewater goby {Eucyclogobiu.r newberrya). The tidewatex goby (TG) is listed as a federally endangered species by the USFWS. TG was nat observed during the site assessment. Tppically,tl�e TG is typically found in marshes,estuaxies, and lagoons where water is still, but not stagnant. Redwood Creek is tidally influenced and teceives stormwater runoff. The TG has a low potential occur within or near the project area. • Califomia black rail (Lateradlusjamaacen.ris cotimuculus). The California black tail (CBR) has been designated by the CDFW as threatened and fully protected. Tall grasses and dense areas of pickleweed neax the tidal flooding zone of the creei�provide suitable nesring habitat. CBR was not observed duting the site assessment, and no suitable habitat was found within the proposed project area. The presence of adjacent suitable habitat suggests that CBR may occur within ar near the project area. � California clapper rail (Aallars Iongirostrl.r ob.rodetsss). The Califo�nia clapper rail (CCR) is listed as an endangered species by botl� the CDFW and T1SF�v'S. CCR was not observed dw�ng the site assessment,and no suitable habitat was found�t�ithin the project area. However,areas surrounding the project axea contain suitable habitat for the CCR. The CCR may be present within or near the project area. � Califomia least tern (Stemula an�illarrrnr hm�nz). The California least tern (CL'1� is listed bp the USFWS as endangered due to the loss of foraging and coastal habitat. No CLT were y-I � US �01 I'ed�.rtriun Undercr�ssing and Bair .Island Aoad Storin DrAan Pump Stataon Project
