Best Management Practices

The control of nonpoint pollution in the U.S. is based on the identification and promotion of best management practices or BMPs, including retention ponds (contain permanent water storage), detention and extended detention ponds (dry out between storms), vegetative filter strips or buffers, and infiltration BMPs, such as infiltration trenches, medians and swales.


Dredging


Depending on how and where it is accomplished, the disposal of dredged material may have substantial effects upon natural resources in the disposal area. Currently, more than 3.8 million cubic meters of material are removed annually from the channels of the estuary to maintain adequate water depths for Charleston's ship traffic.


Golf Courses

Maintain non-chemically treated vegetative buffer zones of at least fifty feet adjacent to all natural watercourses to assist in filtering nutrients and pesticides in runoff and to moderate water temperatures.
