Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

on water stages at certain times of the year, and beneficial responses are

anticipated to begin immediately with the operations of the reservoirs. Actual

restoration of colonization numbers in Lake Okeechobee and WCA-3 may take

several nesting seasons.

5.4.4.5 Sequencing and Adaptive Assessment

The CERP consists of 68 major components and six pilot projects. Significant

uncertainty associated with the individual compartments and the

Comprehensive Plan was recognized during the Restudy. There are a large

number of potential combinations of these compartments that may result from

differences in design and operational schedules developed through the PIR

process. Even as planning efforts for the separate projects evolve, there are also

changes in budgets, policies, resource demands, and operation principles. As

such, a fundamental implementation principle for the CERP is to utilize

adaptive assessment and management in order to continually refine and

improve the performance of the CERP. Incremental revisions throughout the

planning and implementation process of the CERP will lead to optimal designs

and operations of projects to improve performance. The order and schedule for

project implementation will also be optimized to achieve the desired ecological

responses. The use of the adaptive assessment policy minimizes the effects of

uncertainty with respect to the effects of CERP projects on the natural system

and other water-related needs of the region related to the design and

implementation of the CERP.

5.4.4.6 Construction Cost Estimates

No statistical analysis of cost risk was performed. Normal design variances are

expected and normal contingency values are used. The risk of cost overruns is

considered to be low.

5.4.4.7 Project Schedule

It is not anticipated that any new tasks will be required that would increase

overall project delivery dates. As such, no negative impacts to project schedules

are anticipated.

5.4.4.8 Land Available and Acquisition Issues

There is some uncertainty associated with the land availability, cost, and time to

acquire the additional lands necessary for the construction, operation, and

maintenance of Alternatives 2 and 3.
