TABLE 6-7: TOTAL INTEREST DURING CONSTRUCTION

COST COMPONENT

Construction Features $832,761,089

Real Estate $80,134,000

Total Initial Cost $912,895,089

Interest During Construction

IDC Construction $77,244,499

IDC Real Estate $16,518,781

IDC Recreation $31,766

Total Interest During Construction $93,795,046

The cost of a project is the investment incurred up to the beginning of the period

of analysis. The investment cost at that time is the sum of construction and

other initial cost such as real estate and PED cost plus interest during

construction. The IDC for the construction element of the selected alternative

plan is $77,244,499.

Interest during construction was computed for real estate using the date the

lands are to be certified for the project. The total IDC on real estate is estimated

to be $16,518,781. The average annual water quality monitoring costs are

estimated to be $350,000 (see Annex F).

6.2.3 Operation, Maintenance, Repair, Replacement, and Rehabilitation Costs

Annual operation and maintenance costs were estimated for the construction

features of the selected alternative plan. The operation and maintenance costs

were determined by extrapolation from operational cost histories supplied by the

SFWMD, by using industry standard cost data and by using data from past and

projected future cost trends. The average annual operation, maintenance,

repair, replacement and rehabilitation (OMRR&R) costs are estimated to be

$2,413,982 (Table 6-8).
