State Route 140 Ferguson Slide Rock Shed Project (Project) (California Endangered Species Act Incidental Take Permit No. 2081-2014-078-04 (ITP))

State Route 140 Ferguson Slide Rock Shed Project (Project) (California Endangered Species Act Incidental Take Permit No. 2081-2014-078-04 (ITP))

The project involves the construction of a 700-ft long rock shed along the existing alignment of SR 140 to reestablish two-lane traffic in an area previously impacted by a major rockslide. The rock shed will be a reinforced concrete box structure supported on concrete piles, anchored with tie-backs into the south canyon wall, and supported on the river side by concrete columns. Retaining walls will also be required on the approach ends of the structure. The project will result in impacts up to approximately 3.0 acres of limestone salamander habitat including temporary impacts up to a max of 1.72 acres; the project will permanently remove 1.28 acres of Limestone salamander habitat. The project is expected to result in incidental take of limestone salamander, which is designated as a threatened species under the 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.
