Document Description
NOTES: Addendum Supplemental/Subsequent EIR and Review per Lead / Reference SCH# 1997071087 and 2010081056 The proposed project involves construction of a dike to protect the CIW facility across adjacent properties owned by the Corps and Orange County Flood Control District. The dike would be constructed by removing soil material from a borrow area to the south, constructing an earthen embankment along the western and southern border of the facility, and armoring the reservoir side of the dike with rip rap. The dike on the west side of the institution would be approximately 2,860 feet in length, and the top of the dike elevation would range from between 566 and 568.6 feet above mean sea level (amsl). The dike along the southern part of the facility would be 2,910 feet in length. The elevations on top of the dike would vary from 566.0 to 568.6 feet amsl, depending on exposure to the reservoir and computed wave height. Both dikes would have a top width of 15 feet and side slopes of lV on lH. The reservoir side of the slope would be protected by an 18-inch-thick riprap over a layer of filter cloth. A ponding area with a storage capacity of 16.3 acre-feet between elevations of 551.0 and 557.6 feet amsl would be provided with a 36-inch diameter culvert for draining water that has collected in the interior of the dike into surrounding reservoir lands.
