Section 10 Recommendations

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

10-1

10.0 RECOMMENDATIONS

I am recommending a plan that is designed to capture, store and redistribute

fresh water previously lost to tide and to regulate the quality, quantity, timing

and distribution of water flows, that is an integral part of the CERP. The CERP

will play an important role in reversing the environmental impacts that have

occurred for the past fifty years as a result of the existing C&SF Flood Control

System. The lack of storage in the Everglades system, particularly during wet

periods, has led to ecological damage to Lake Okeechobee’s littoral zone and

damaging regulatory releases to the estuaries and the WCAs. Conversely,

during dry periods, this lack of storage results in water supply shortages for both

the human and natural environment. The overall objectives of the EAA Storage

Reservoir project are to improve timing of environmental deliveries to the WCAs

including reducing damaging flood releases from the EAA to the WCAs, reduce

Lake Okeechobee regulatory releases to estuaries, and meet supplemental

agricultural irrigation demands. The Project includes one of the ten CERP

projects conditionally authorized by Congress in section 601(b)(2)(C)(ii) of the

WRDA of 2000, Public Law 106-541.

I find that the EAA Storage Reservoir Project, located in western Palm Beach

County, is an integral part of CERP. The Project will have two Compartments

with a total storage capacity of up to 360,000 acre-feet. Environmental

restoration is achieved by improving the quality, quantity, timing, and

distribution of water within the Everglades, providing wetlands, aquatic deep

water refugia, littoral zones, and terrestrial habitat around and within the

reservoirs. Supplemental agricultural water supply within the EAA during dry

periods is currently met by deliveries from Lake Okeechobee. Additional water

storage within the EAA would lesson its dependency on the lake for irrigation

water. Flood damage reduction, while not a primary project objective, is

attained by increasing canal conveyance capacity in the canals and by providing

storage capacity in the surface impoundments. To ensure that water that is to

be delivered to the WCAs and ENP meets water quality requirements, a

conceptual stormwater treatment area is included in the plan. Approximately

1,495 acres of land already owned by the State of Florida and the SFWMD

adjacent to and in the southwest corner of the reservoir have been identified as

the likely site for the STA. Additional analysis will be conducted prior to the

Final PIR and during the detailed engineering and design phase of the project to

refine the design, cost, and operations of this STA. Sizing and optimization of the

proposed STA may include converting a portion of Cell 2 to a STA as well.

Therefore, I recommend that the EAA Storage Reservoir Project as described in

Section 6 of this report be authorized with such modifications thereof as in the

discretion of the Chief of Engineers, may be advisable, for construction. The

total estimated project first cost is $912,895,089 with an estimated Federal first
