Forgive me, but isn't this the final environmental assessment the Army Corps of Engineers produced?

More to the point, is there a reason to trust Jo-Ellen Darcy's opinion over that of Douglas Lamont and Colonel John W. Henderson, P.E.? (It seems like of the three, the Colonel's opinion is the least likely to be politically biased and most likely to be based on engineering judgement.)
EDIT: Actually, I think I might have been overly harsh on Mr. Lamont here. He is also a PE, and was appointed in 2004, which makes me think he might not be in a political job, either. http://asacw.hqda.pentagon.mil/Lamont.aspx
