The Amended ITP (Amendment No. 1) amends the original ITP executed on May 19, 2020, to include design refinements that change the Project description and expand the Project footprint to the already approved LEBLS Project. This Project involves the set back of levees protecting the Lower Elkhorn Basin, including the Sacramento Bypass North Levee and a portion of the Yolo Bypass East Levee, thereby increasing the capacity of the Yolo and Sacramento Bypasses and reducing flood risk on the upper Yolo Bypass and Sacramento River. The Amended ITP includes design refinements and footprint expansion to the following: the staging areas; detention pond; storm drain pipe construction; widening of existing Ditches 10, 12, and 13; concrete erosion control at the North Cross Canal Culvert; new ditch access crossings; new culvert crossing in Ditch 13, haul crossing across Ditch 13; and additional grading at the South Cross Canal. The Project will also implement several ecosystem elements that have been designed to offset effects to biological resources resulting from the LEBLS Project activities, through the enhancement of features for sensitive species. The Amended ITP updates the direct impacts of the Project based on the refined Project description, Project footprint, and an updated assessment of Covered Species habitat impacts.
