Document Description
The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2019-0035-R3, pursuant to Section 1602 of the Fish and Game Code to John Truchard. This project is being implemented in response to a Notice of Violation letter, prepared by CDFW, dated October 12, 2018. The project will restore an unnamed tributary that was impacted in 2017 by doing the following: (1) Restoring a seasonal wetland, (2) installing a 60-inch corrugated metal pipe stilling basin and a 13-foot long, 18-inch wide culvert that will pass storm water from the stilling basin into the existing sedimentation basin (i.e. the restored seasonal wetland), 3) restoring approximately 170 linear feet of a deeply incised stream channel that is upstream of the sedimentation basin, 4) upsizing an existing 15-inch diameter culvert with a 24-inch culvert in order to adequately convey the estimated 100-year flood, and 5) provide on-site restoration in the form of native revegetation and invasive species removal along 518 linear feet of streams on the property.
