Galveston District Mission Statement

Port of Houston, Courtesy PhotoThe USACE Galveston District plays a key role in America’s well-being by keeping waterways open for navigation and commerce. The Galveston District is directly responsible for monitoring more than 1,000 miles of channel.  Dredges are constantly at work keeping vital marine arteries open for waterborne traffic carrying cargo ranging from crude oil to coffee. Other priorities include construction of jetties or breakwaters to protect harbor and inlet entrances and the locks along the Gulf Intracoastal Waterway at the crossing of the Brazos and Colorado rivers.

In the photo: The Port of Houston ranks first in the nation in foreign waterborne tonnage; first in U.S. imports; and second in the nation with respect to foreign and domestic tonnage.

Federal Channel Setbacks

The intent of these Standard Operating Procedures (SOPs) is to provide a rapid and repeatable procedure for evaluating the construction of structures and/or the deposition of dredge and fill along federally maintained channels in order to preserve the government's ability to maintain such waterway and provide a margin of safety to those who use such waterway by maintaining established setbacks from federal channels. These SOPs apply to all Department of the Army permit applications pursuant to Section 10 of the Rivers and Harbor Act of 1899 and/or Section 404 of the Clean Water Act.  Graphic representations of the established setback lines are available for viewing in Google Earth.
