Section 3 Future Without Project Conditions

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

concentrations have also decreased in the EAA canals over the past decade. This

trend should continue under the “without project” condition.

Concentrations of some key pesticides that are frequently found in the EAA

canals have declined precipitously over the past three decades. For example,

average canal water concentrations for atrazine have declined from 1.2 to

0.6 μg/L since the 1980s. The average simazine concentration has declined from

2.2 to 0.08 μg/L over the same period. This trend should continue through 2050.

3.1.12 Sediment Quality

The flat terrain of the EAA limits the movement of water through the canals.

Generally, water movement occurs only when water is pumped. As a result,

there is little erosion and deposition of sediments in the canals and little

maintenance dredging of the canals. Thus, during the planning period through

2050, the sediments should show little change from existing conditions in the

“without project” condition.

3.1.13 Socioeconomics

In general, South Florida should continue strong economic and population

growth through 2050. The areas on the east coast of Martin and St. Lucie

Counties and west coast of Lee County should participate in this growth. Other

localities in the area of interest would not share in this overall trend. The

important features of the economic landscape are agricultural activity, fishing,

tourism, and recreation and should continue to be the case for 2050.

The Caloosahatchee River region is one of the fastest growing areas in the

nation. The population is expected to increase 63% by 2015. Then the growth

rate should level off to achieve an additional 36% by 2050. Population in Martin

and St. Lucie Counties should double by 2050.

Despite population loss in the EAA between 1990 and 2000, the area should see

significant population growth in the planning period. Palm Beach County’s

population is projected to increase 64%, from 1.13 million to 1.86 million, over

the thirty year period from 2000 to 2030 (BEBR, 2002). Assuming a

conservative 1% annual growth rate between 2030 and 2050, Palm Beach

County’s population would grow to 2.27 million. Hendry County has a much

smaller population but should grow 71%, from 36,000 to 62,000 between 2000

and 2030. Assuming the same 1% annual growth rate from 2030 to 2050,

Hendry County’s population would grow to 75,000 persons.

Compartment A under the “without project” condition would not have significant

direct or indirect effects on population within the EAA or the South Florida

Region as measured by displaced population from Compartment A and induced
