How much sediment would be dredged in the pelagic zone?
Ms. Lukasiewicz responded: For the purposes of this FS it was assumed that the entire pelagic zone would be dredged; removing sediments greater than 10 cm. This volume is estimated to be about 177 million cubic meters. It was determined through modeling evaluations, that there was no advantage to isolating areas of the pelagic zone for dredging, or targeting specific depth intervals to be removed. Known Project Uncertainties There are uncertainties with all the alternatives evaluated, Ms. Lukasiewicz continued. Project Uncertainties include: Findings presented in this Feasibility Study are in a large part associated with the expectation and assumption that the Comprehensive Everglades Restoration Plan (CERP) goals, as currently understood for watershed phosphorus reductions, can be achieved by the year 2015. Modeling into the future, especially as it relates to projecting climate, water flow and sediment burial rates presents uncertainties. There is a 30 – 50%, degree of uncertainty in
