Document Description
The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement number 1600-2020-0035-R3, pursuant to section 1602 of the Fish and Game Code to the project Applicant, Rich Boberg. The Project includes work activities to stabilize the creek banks, to prevent continued erosion of the creek banks and incision of the creek bed, and to widen the creek to allow for passing of 100-year event flows. The pieces of concrete floodwalls installed during the 1950s or 1960s that have fallen into the creek will be removed. A standing, previously installed, 30.3-foot-long concrete floodwall that has erosion undercuts will be removed. Grading along 117 linear feet of the creek banks, totaling 1,951 square feet, will be conducted to stabilize the creek banks by reducing the bank slope and to create a wider creek cross section to accommodate high flows. Alluvial bed material graded from the east bank will be used to fill an incised section of the creek bed where erosion has occurred. There will be 440 square feet of rock placed in 3 locations within the creek bed to protect an existing sewer pipeline and to prevent further bed incision. Willows cuttings will be planted within the rock.
