Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

has the advantage of potential enhancement of STA operation by intercepting

peak flows during wet periods and retaining water during dry periods while

metering water output to the STAs.

Depending upon placement and the size of the reservoirs, this option may

remove property from the tax roles in Palm Beach County, with its associated

negative impacts on the socioeconomic components of the environment in this

county. However, it should be noted that the Talisman lands within the EAA

have already been acquired via an appropriation of Federal funds and SFWMD

funds in anticipation of implementation of a project contributing to the overall

restoration of the South Florida ecosystem. According to the Palm Beach County

Property Appraiser, the value of land in the EAA decreases with distance from

Lake Okeechobee. Land near the Everglades Construction Project STAs and

WMAs at the south end of the EAA was valued at a little more than 40% of the

value per acre of the land next to the lake. Apparently, this is related to the

relatively poor agricultural productivity of this land when compared to the land

adjacent to the lake. For the same reason, large acreages of land are available in

the southern end of the EAA. Some of the parcels in this area are also adjacent

to STAs to receive reservoir water and the canals to connect the reservoirs with

Lake Okeechobee.

5.2.2 Conclusions

Based on the above-described screening analysis, there is no compelling reason

to pursue meeting the planning objectives elsewhere within the study area.

Also, cost-effectiveness analyses performed during the Restudy demonstrated

that the EAA storage reservoirs were more cost-effective on a cost per acre-foot

of storage than most of the options described above. Table 5-1 displays the

average annual cost per acre-foot storage. Although the C-43 basin was also

demonstrated to be more cost-effective, the cost of back-pumping the stored

water “through the lake” to meet the EAA planning objectives is not captured in

this cost and would greatly increase the cost of storing water in this location.

TABLE 5-1: COST PER SQUARE-FOOT OF WATER STORED.

Option Cost* per Acre-Foot

Storage North of Lake Okeechobee $374

Storage West of Lake Okeechobee (C-43) $134

Storage East of Lake Okeechobee (C-44) $328

Aquifer Storage and Recovery (ASR) $822

Storage South of Lake Okeechobee in the EAA $181

* In 1999 dollars

In summary, initial screening determined the project as described in the

Restudy achieves the desired benefits in a cost-effective manner. Based upon

the information, it is apparent the best location for the proposed reservoirs is
