The majority of dredging in Texas is presently undertaken by governmental agencies to support navigational interests in both waterways and harbors. Lesser dredging activities that occur within the private sector include the dredging and maintenance of channels, turning basins, marinas, and other coastal facilities. The material dredged can be described as either maintenance material or virgin material. Virgin material is generally composed of emergent or submergent silt, sand, clay, or other particles which have been deposited from an overlying water column into an existing dredged waterway of harbor. Once these materials have been dredged, they must be placed in designated disposal areas. The selection of disposal sites can be a complex process involving various environmental and economic considerations. The objective of this study was to provide information relevant to minimizing the environmental impact of necessary navigational improvements and evaluating the trade-offs associated with navigational development. The results of this study are presented in three volumes. The accomplishment of the tasks establishes a means of developing a disposal plan for Texas which includes parameters and criteria for determining the types of disposal sites acceptable, unacceptable, and marginal for the disposal of dredged material.
