President Obama’s recently released 2015 budget doesn’t include construction money for the Savannah Harbor deepening project, something that has upset Georgia leaders, and threatens future agriculture-based exports in the region.

Last week, all of Georgia’s congressional delegation sent a letter to Sylvia Burwell, director of the Office of Management and Budget, expressing their disappointment in the office’s failure to support the Savannah Harbor Expansion Project, or SHEP.

“The president previously included SHEP in his 2012 ‘We Can’t Wait’ initiative, in which he specifically pledged to expedite SHEP and four other port projects. Just seven months ago, Vice President Biden visited the port in Savannah and said the project would be expedited and built ‘come hell or high water,’” the letter stresses.

According to the letter, the Consolidated Appropriations Act of 2014, signed by the president Jan. 17, “gave clear direction to the administration to begin construction on SHEP and to request the necessary funding. The administration’s position, as evidenced by the Office of Management and Budget, is that they will ignore the explicit guidance from congress, and will instead request more funding for studies this year, further delaying the project.”

With a cost-benefit ratio of 5.5 to 1 and an annual net benefit to the nation of $174 million, SHEP has wide support, the letter continues.
