Again, acreage means nothing without volume. And depending on the area, and the soundings in that area, that volume will differ. That is the EXACT REASON why contractor bid it by volume. Which is why using $/acre in planning is not an accurate measure if you are not accounting for the volume. What volume is your $50k/acre based off of? Where are you pulling these numbers from? Is $50k based on 3 feet? If so, that is a VOLUMETRIC calculation. Which is my entire point. However, if you are taking statewide averages of actual projects, then a) it's likely bid by the cubic yard and b) if its bid by the acre, then the project SHOULD specifically state the assumed depth of dredge which would then give you your volumetric measure. In addition, if you dredge out these areas only 2-3 feet, that will have to be redone much more regularly than every 20 years. 1 storm surge could wipe that out, depending on the severity of the storm.

You are arguing completely unrelated issues and with little comprehension of the industry. The $50,000/acre figure is industry standard for restoration of land within 5 miles of the river. The figure is also backed up with real bid results for restoration in the region and basin.
Lastly, the dredge depth is not 2-3 feet … that is the depth of the disposal. The final elevation of the marsh is 6-8’ high. It would not require additional dredging before 20- years.

How many acres are you dredging?
What is the existing mudline elevation?
What is the proposed bottom of dredge elevation?
Where is the dredge disposal area?
What is the existing elevation of the dredge disposal area?
What is the proposed elevation of the dredge disposal area?

You may use a general $/acre but that is not an accurate measure of dredging. You can disagree with me all you want, but the questions above all boil down to volume. A dredger is going to quote you based on the volume of the dredge. The state may track it by acre but that doesn't accurately tell you how much you are dredging. Volume matters. I'm not arguing this anymore, have yourself a good weekend.
