Book Description
The recommended plan will convey design outflows of 30,000 cu. ft/s from Prado Dam to 47,000 cu. ft/s at the Pacific Ocean. The project consists of acquisition of the post project overflow area along 8 miles of river just downstream of PRado Dam (Prado Dam to weir Canyon Road) and 23 miles of improved channel (Weir Canyon to the Ocean). The reach from Prado Dam to Weir Canyon would remain in a natural rural condition for wildlife and open space value. The improved channel will consist of sections of trapezoidal riprap or grouted riprap channel, trapezoidal concrete-lined channel and rectangular concrete-line channel. The ocean outlet will consist of rock mounded jetties. In addition, the Greenville-Banning Channel would be modified to join the Santa Ana River about 1 mile upstream of the Pacific Ocean. Talbert Channel will be relocated 1,000 feet upcoast from its present location to accommodate relocated 1,000 feet upcoast from its present location to accommodate widening of the Santa Ana River at the ocean. the channel access and maintenance roads would be incorporated into the overall recreational trail system for the entire river. a 92-acre marsh will be restored at the mouth of the river for the preservation and enhancement of wildlife.

Book Description
The recommended improvement to the existing flood control Prado Dam, which was completed by Corps of Engineers in 1941, consists of enlarging the reservoir capacity by raising the spillway crest 20 feet and the top of the dam 28.4 feet to elevations 563 and 594.4 feet, respectively. A new gated outlet structure capable of releasing 30,000 cubic feet per second, an auxiliary dike, and a dike along the Corona Expressway would be provided. Approximately 1,660 acres of land up to elevation 566 feet would be acquired for the enlarged reservoir. Interior dikes would be provided for the protection of the existing facilities at the Corona Sewage Treatment Plant, Alcoa Aluminum Plant, Corona Housing Tract, and California Institution for Women. The cost for the recommended improvement is estimated at $212,623,000, including $116,274,000 for land acquisition. (fr).

Book Description
The recommended plan for Oak street Drain consists of a concrete channel beginning at the existing Oak Street debris basin and extending over 3 miles to the confluence with Temescal Wash. The channel is designed to provide 100-year level of protection. Total project first cost is estimated at $20,652,000. The economic data for the project is contained in Volume 9, 'Economics and Public Comment and Response.' (FR).

Book Description
Seven Oaks Dam, located 8 miles northeast of the city of Redlands in San Bernardino County, will be an earth and rock fill structure with a height of 550 feet above the existing streambed, crest width of 40 feet, crest length of 2,980 feet and crest elevation at 2,610 feet NGVD. The upstream and downstream slopes will be 1 vertical on 2 horizontal. The dam will have a storage capacity of 145,600 acre-feet at the spillway crest elevation of 2,580 feet NGVD. (FR).

Book Description
The Santa Ana River Mainstem Project, including Santiago Creek, is designed to provide urban flood protection to the growing communities in Orange, Riverside, and San Bernardino counties. The project will provide various levels of flood protection ranging from 100-year to 190-year in areas most susceptible to damages from floodflows for over 2 million people and businesses within the three-county area. Most of the development is in the Lower Santa Ana River Basin (Orange County). The project will provide environmental enhancement in a currently degraded marsh area at the mouth of the Santa Ana River, thereby providing significant value as a wetland habitat for migrating waterfowl and fot the California least tern, a federally listed endangered species. The project is intended to provide increased recreation opportunities through project related recreational developments on the Lower Santa Ana River and on Santiago Creek. Water conservation is not an authorized project purpose, but incidental water conservation benefits would be realized as a part of the recommended plan. (FR).
