Section 2 Existing Conditions/Affected Environment

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

2-55

Canals sediments in the primary canals--Miami, North New River, Cross, and

Bolles--have been sampled and analyzed in conjunction with the SFWMD

DBHYDRO database. Data indicates that sediments contain persistent

pesticides--DDT and its degradation products most prevalent. The sum of DDT

and DDT products in recent samples reaches one- to five-tenths of a milligram

per kilogram of sediment [0.1 mg/kg (ppb)–0.5 mg/kg (ppb)] are shown in Table

2-5.

When these values are compared to action levels (Chapter 62-777, F.A.C), the

comparison reveals that canal sediment samples will typically exceed the SQAGs

but never exceed State of Florida clean-up targets. Given the present elevated

chloro-pesticide levels, and the disposition of the media within which it is

contained, no remediation of canal material is required. However,

environmental protection measures shall be specified for the construction phase

of the proposed project. These measures will consist of, but not be limited to, the

use of turbidity curtains, settling basins, and the encasement of canal materials

in the constructed levees, as appropriate.

2.21 TRANSPORTATION, UTILITIES AND PUBLIC INFRASTRUCTURE

Due to its primarily agricultural and rural nature, local public infrastructure in

the EAA is very limited. The only public utilities that provide services in the

EAA are operated by and generally limited to the city limits of the small cities of

Belle Glade, South Bay and Pahokee on the south side of Lake Okeechobee.

The road network in the EAA is also limited and is a mix of municipal, county,

state and federal roads, located primarily in the northern portion of the EAA.

State Road (SR) 80 is a major east - west road that runs through this area

between West Palm Beach and Ft. Myers. Located immediately east of the

proposed EAA Reservoir project is US 27 (also known as SR 25). It is the only

major north – south road in this area and runs parallel to the west side of the

North New River Canal (also known as the L-18 / L-19 / L-20 canal) from the

Dade – Broward county area north to South Bay and then west around the

southern and western portions of Lake Okeechobee where it then heads north in

the state. US 27 is a major north-south route in and out of south Florida for

evacuation and commerce purposes. Most of the road network outside the
