Section 3 Future Without Project Conditions

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

and maintain the secondary water control structures and pump stations

(Fernald and Patton, 1984).

Water levels in the lake should continue to be managed through 2050 according

to a regulation schedule that is jointly developed by the SFWMD and USACE.

The schedule would likely be modified as other CERP projects are completed.

The present schedule is designed to maintain a minimum level during the wet

season in order to provide storage capacity for excessive amounts of rainfall and

to prevent flooding in surrounding areas. With completion of above ground

reservoirs and STAs in the Lake Okeechobee watershed and the proposed C-43

basin between the present and 2050, it is reasonable to expect that both this low

level and the maximum stage at the end of the wet season would be reduced

accordingly. Through 2050, the Caloosahatchee and St. Lucie Rivers should

remain the primary outlets for release of flood waters when the Lake is above

regulation schedule stages.

3.1.3 Climate

The observed trend for global warming is expected to continue, but with little

effect in the EAA. The attendant 0.8-foot rise in sea level is not expected to

influence the project site, given its interior location, and would not affect plan

selection. The final array of plans all consists of 360,000 acre-feet reservoirs in

various configurations. The local climate of the EAA should not change from the

present to 2050.

3.1.4 Air Quality

Air quality between the present and 2050 should not change significantly from

existing conditions.

3.1.5 Noise

As additional areas are developed within designated growth boundaries around

cities, noise from general traffic, construction, and other vehicles would be

expected to increase modestly between the present and 2050.

3.1.6 Vegetation and Cover Types

3.1.6.1 Lake Okeechobee

Without the EAA Storage Reservoirs project, there would be continued use of

Lake Okeechobee to store water for agricultural and flood control needs. High

water levels in the lake would continue to adversely affect shallow littoral zone

habitat, and deeper littoral zones would remain without vegetation in 2050. In
