Section 6 The Selected Alternative Plan

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

6-22

6.4.2.3.2 Construction Materials

The superstructures for all pumping stations are constructed with reinforced

concrete. For large pumping stations, the substructure is constructed with mass

concrete. Substructures for medium and small pumping stations are constructed

with reinforced concrete.

6.4.2.4 Bridges

The S-609 box culvert structure will be constructed underneath U.S. Highway

27. This structure will serve as a hydraulic connection between the EAA

reservoir and the North New River Canal. More detail on structure S-609 is

provided in Section A-2.4.2.2.1.2 and Plate C-5 in the Engineering Appendix

(Appendix A).

Bridge relocations will be required due to channel improvements in the Miami,

North New River, Bolles and Cross Canals.

6.4.3 Mechanical and Electrical Requirements

6.4.3.1 Utility Relocation

6.4.3.1.1 General

Since the EAA is located in a rural and largely undeveloped area in

southwestern Palm Beach County, the need for utility relocation has been

minimized. Conflicts with existing or proposed utilities have been avoided by

design modification whenever possible. All known necessary utility relocations

are detailed in Appendix A, since accounting for the impact of any construction

interference is an essential part of project planning.

Conveyance canal improvements for the North New River canal will involve

widening of the canal, and, because of this work, utility relocation is anticipated

in conjunction with the replacement of two bridges. Fiber optic communication

lines are attached to one bridge, and a water main to the other. Relocation of

utilities attached to bridges will be included as part of the bridge construction

project. A high voltage electrical transmission line, and an aerial electrical

distribution line and telephone line will also require relocation due to canal

improvements near Lake Okeechobee. Relocation of an overhead electrical

distribution line and telephone line the crosses through the reservoir area is also

anticipated. The need for additional required utility relocation may be found

once pre-construction project survey information is available.
