Allen Myers Drainage Pump Project (Streambed Alteration Agreement No. 1600-2015-0184-R2)

The California Department of Fish and Wildlife has executed Streambed Alteration Agreement number 1600-2015-0184-R2, pursuant to Section 1602 of the Fish and Game Code to Allen Myers. The project consists of the installation of new 118 (ft.) long, 18-inch (in) steel epoxy coated pump discharge pipe approximately 6-inch higher on the levee than the existing culvert. The new steel pipe will convey water from a lift pump within the retention ditch to Freshwater Creek. The project will also include the installation of an 18-in positive closure device and siphon breaker. A 17-ft long section of the steel pipe will convey water in the existing concrete structure above the ordinary high water mark on the bank of Freshwater Creek. Once installed water from the steel pipe will discharge into the existing concrete water structure located within the Creek; therefore erosion of the creek banks will not occur. Approximately 30 cubic yards of native fill on the level with be disturbed in order to install the new culvert pipe. After the pipe is installed, all disturbed soil including the banks of Freshwater Creek will be compacted to the Department of Water Resources levee compaction standards using a vibratory plate compactor. The existing 24-in culvert pipe within the levee will continue to act as a gravity fed drain.
