Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

5-71

the CERP can not function as source of additional water to the WCAs or ENP

without extensive modification and likely substantially increased cost (compared

to original designs and cost estimates).

Furthermore, since the land for this project has already been acquired by the

Federal Government and the State of Florida for ecosystem restoration in South

Florida, and further considering that implementation of additional storage at the

project location will immediately result in the ability to reduce the harmful

effects of high water levels on the littoral zone in Lake Okeechobee and reduce

the magnitude and frequency of regulatory releases from to the Caloosahatchee

and St. Lucie estuaries, the immediate, independent beneficial effects of the

EAA Storage Reservoirs project justify project implementation, even if no other

CERP projects are authorized or implemented. In fact, the need for additional

regional storage at this location to accomplish these objectives is so acute that

the State of Florida has begun advance design and construction work on a

component of this project through its "Acceler8" program; initial construction on

the Acceler8 project is scheduled to begin in 2006.

5.7.1 Risk and Uncertainty

As noted in section 5.4.2.1.4.1, once existing constraints on operations are

reduced and/or eliminated such that additional water could be delivered in a

manner consistent with restoration goals, total volumes of water made available

by the EAA Reservoir project for introduction to the Everglades Protection Area

are anticipated to be greater than existing levels. Because the volumes of water

delivered into the Everglades Protection Area under “restored” conditions are

likely to be greater than existing volumes, it is possible that additional STA

optimization and/or capacity might be required to handle the additional

hydraulic and nutrient loading rates associated with CERP-like deliveries. The

potential need for additional STA optimization and/or capacity is being

investigated including development of Planning level cost estimate in the Final

PIR

5.8 TRADE-OFF ANALYSIS

Habitat units were weighed equally and summed to arrive at total habitat unit

outputs for each alternative. This method takes into consideration the trade-offs

in environmental performance for each of the natural system areas evaluated to

achieve the best possible overall beneficial effect that can be achieved with a

single optimized reservoir plan.
