Document Description
The Alameda County Transportation Commission in association with the California Department of Transportation (Permittee) proposes the widening of SR-84 from two lanes to four lanes and modifications to expressway standards from south of Ruby Hill Drive and the I-680 interchange. The Project will also improve SR-84/I-680 interchange ramps and extend the existing high-occupancy vehicle (HOV)/express lane on southbound I-680 northward approximately 0.8 miles north of Koopman Road, north of the SR-84/I-680 interchange. The Project includes roadway widening; bridge widening; utility and drainage improvements, new bike lanes, frontage roads, flyover ramp, retaining walls, concrete barriers, HOV/express lane signs and gantries, stormwater treatment facilities, and wildlife movement crossing structures. The project as amended will also include 6.4 acres of tree planting at the Eagle Ridge Preserve East. The Eagle Ridge Preserve East planting will consist of 1,030 oak trees Quercus argifolia and Quercus lobata (Quercus spp.) being planted with associated irrigation lines over an area of 6.4 acres. This effort will temporarily impact a total of 0.17 acres of CTS suitable habitat. No permanent impacts will occur from tree planting activities associated with this amendment. The project is expected to result in incidental take of the Covered Species, as defined by Fish and Game Code in the form of pursue destruction of burrows and dens that the Covered Species inhabit; being crushed under moving vehicles and equipment; disturbance in the vicinity of dens or burrows; desiccation or predation along fence lines and other barriers to movement; and habitat alteration and decreased survivorship resulting from the installation of additional light sources, resulting in increased light pollution to Covered Species habitat. Take may also occur in the form of pursue, catch, capture, or attempt to do so from capture and relocation attempts. Relocation could result in mortality, injury, and/or disease transmission to Covered Species, both designated as a threatened species under CESA. The ITP referenced above as issued by CDFW authorizes incidental take of species listed under CESA that may occur as a result of Project implementation.
