This diversion could create more wildlife habitat and could potentially improve fisheries. This would require prior planning, operational experience and ongoing management. Although the cost and efficiency would have been low, there was a great deal of concern regarding the concentrations of heavy metals and pesticides in both the water and sediment. A 5-year research project was conducted by the U.S. Army Corp of Engineers to reuse material from spoil banks. Some suggestions included deposition as a substrate for wildlife habitat, beach renewal, restoration of bare ground, road construction material and sanitary land filling.
Regulatory controls have the advantage of affecting the entire coastal zone area.
It requires builders comply with standardized practices. Remediation efforts have been suggested to reduce the impact of saltwater intrusion. Impoundment or semi-impoundment by constructing low levies with spoil material close to the marsh edge to limit water exchange. Little is known about lthis technique's long term effectiveness. Impoundments do not allow for fish migration.
