But growing pressure for flood control and navigation improvements led to calls for federal involvement and to the 1879 establishment of the Mississippi River Commission, a body that included three members from USACE. The commission was authorized to build and repair levees largely to aid navigation, but dramatic Mississippi flooding in 1912 and 1913 led to federal legislation aimed specifically at flood control.
The first Flood Control Act of 1917, pushed by Democratic Sen. Joseph E. Ransdell of Louisiana and Democratic Rep. Benjamin G. Humphreys II of Mississippi, appropriated $45 million for flood control on the Lower Mississippi. A second Flood Control Act came in 1928, spurred by a catastrophic 1927 Lower Mississippi River flood that inundated more than 16 million acres, forced 500,000 people from their homes, and killed more than 250 residents.
“That was the big one in terms of convincing the federal government to direct massive resources to the flood control problem on the Lower Mississippi River,” USACE Historian Matt Pearcy said.
The Flood Control Acts drew USACE into a mission it had not participated in prior to 1917. Following the 1927 flood, the chief of engineers, Maj. Gen. Edgar Jadwin, drew up a new comprehensive plan requiring that the water be dispersed through controlled outlets and floodways as well as confined between levees. Congress approved this plan in the 1928 Flood Control Act, placing its implementation under the control of USACE. The legislation launched what today is called the Mississippi River and Tributaries (MR&T) project.
The MR&T project, designed entirely by USACE, is still under way. In 2011, it successfully handled floodwaters surpassing those of 1927, safely dispersing them to the Gulf of Mexico.
USACE’s responsibility for national flood control was codified in the 1936 Flood Control Act, the passage of which was inextricably linked to the New Deal civil works and jobs programs of the era.
The New Deal
Many images, mental and pictorial, of the New Deal are typically of huge water-related projects. This perception dovetails appropriately with USACE’s historical focus on water resources management, a mission that continues today. But the 1930s drive for New Deal civil works projects engaged USACE as never before, expanding its emphasis from navigation and flood control to multipurpose projects.
New Deal water management construction including dams provided flood control, irrigation, navigation, water supply, hydropower, and recreation. Navigation remained a priority with the dredging of a 9-foot channel on the Upper Mississippi, Ohio, and several other major tributaries.
USACE’s civil works portfolio expanded significantly during the New Deal. A slew of projects studied for possible execution in the late 1920s suddenly received federal funding and went forward as a result of New Deal initiatives. Their intent and execution were later echoed in the “stimulus bill” of 2008. For example, USACE historians can point to 1930s-vintage photos of men at work on USACE projects along the southeast Washington, D.C., waterfront that compare with similar photos of projects performed under the recently completed American Recovery and Reinvestment Act. While the level of mechanization is far different, the symbolism is similar.
Military Construction, World War II
“The Corps of Engineers’ only significant military construction prior to World War II was limited to coastal fortifications. We started with civil works in 1824 and that’s largely what we did, with the exception of coastal fortifications – Fort McHenry and the like,” said Lonnquest.
In the 1920s and 1930s, USACE engineers were utterly absorbed administering the organization’s massive civil works program, whose budget in 1938 was nearly 400 times greater than its military budget. But as the United States geared up for war, the Franklin D. Roosevelt administration judged that the Army Quartermaster Corps was not up to the task of handling the sheer volume of military construction it foresaw.
After the Destroyers for Bases Agreement of September 1940, Army Chief of Staff Gen. George Marshall assigned USACE the job of constructing air bases in the string of British Atlantic territories from Newfoundland to British Guiana. USACE was also asked to begin doing runway construction for the U.S. Civil Aeronautics Administration. In 1941, Congress formally transferred the military construction mission to USACE.
Tapping USACE was a logical decision. It had engineer districts nationwide with experienced construction managers. It also had established relationships with all major American construction firms.
“Overnight the Corps’ workload literally exploded,” Lonnquest explained.
Over the next four years, USACE completed 27,000 military construction projects valued at $15 billion, including housing for 5.3 million soldiers, and aircraft, tank, and ammunition plant construction. It built signature American facilities like the Pentagon, which it completed in 16 months. It put up the infrastructure for the Manhattan Project at a cost of $2 billion, employing 120,000 people in the effort to develop the atomic bomb. USACE also built overseas, preparing staging areas in England and carving out the Ledo Road in Burma.
