A survey of the economic and environmental aspects of an onshore deepwater port at Galveston, Texas. Part II: Environmental considerations.
The development of a deep draft port for the Galveston area is a project with broad implications for the environment. A framework was established for a comprehensive environmental study which should be undertaken in the early stages of planning for the proposed port. An environmental assessment matrix was followed which identified the project activities such as construction, operation, and maintenance for the offshore, Galveston Bay entrance, and terminal areas, as compared with environmental elements such as physical, chemical, geological, biological, and cultural features. Major environmental issues included effects on the Galveston Bay--Gulf interchange, removal of the established bottom in the offshore area, dredged material disposal, sediment transport changes, better oil spill control and containment in the harbor area, and the exponential increase in environmental change with the increasing depth of the project.
