Chuck-
We need to separate river dredging from beach sand pumping. The actual work may be similar but the materials are not. River dredging involves silt and sand. Beach pumping is sand only.
Here’s a link to a story in 2009 about a leak in the Eagle Island “bulkhead” that leaked dredged materials: http://www.saw.usace.army.mil/pao/WIR/WIR_I_37.htm
So river dredging is a commercial need with no larger implications for beach sand pumping.
