Yes Yes Yes Yes Yes Species and critical habitat are from the U.S. Fish and Wildlife Service and National Marine Fisheries Service species lists based on a 500-foot buffer along each alignment. Riparian Area, Domerie Flats Elk Winter Concentration Area, Bullfrog Mill Winter Elk Concentration Area, Bullfrog Mill/Cle Elurri Wood Duck Nesting Area, and the Cie Elum River Riparian Area as well as several other wildlife migration corridors and winter use areas. Alternatives 4A and 4B both bisect the Domerie Flats Elk Winter Concentration Area. Alternative 5 borders the south side of the Domerie Flats Elk Winter Concentration Area. 3.4.3 Ecosystem Resiliency The ecosystem resiliency criteria assesses whether the alternative has the potential to increase resiliency against the impacts of climate change, such as reducing risks associated with extreme flood events. Channel Migration Zones (CMZ) are areas within the floodplain where a stream or river can be expected to move naturally over time due to hydrology and topography. Alternatives 1 through 3 are mostly in Tier 1 CMZ with one area of Tier 2 CMZ near milepost 75. Alternative VOLUME I: FEASIBILITY REPORT 1-90 Corridor Easton to Cie Elum Feasibility Study 144
