Formerly separate units

Separately authorized on 4 July 1838, the Corps of Topographical Engineers consisted only of officers and was used for mapping and the design and construction of federal civil works and other coastal fortifications and navigational routes. It was merged with the Corps of Engineers on 31 March 1863, at which point the Corps of Engineers also assumed the Lakes Survey District mission for the

The survey, based in Detroit, Michigan, was charged with conducting a hydrographical survey of the Northern and Northwestern lakes and preparing and publishing nautical charts and other navigation aids. The Lake Survey published its first charts in 1852. In the mid-19th century, Corps of Engineers' officers ran Lighthouse Districts in tandem with U.S. Naval officers.


Civil War

The Army Corps of Engineers played a significant role in the American Civil War. Many of the men who would serve in the top leadership in this organization were West Point graduates. Several rose to military fame and power during the Civil War. Some examples include

Technology Industry. U.S. Civil War Center The South was initially at a disadvantage in engineering expertise; of the initial 65 cadets who resigned from West Point to accept positions with the Confederate Army, only seven were placed in the Corps of Engineers. The Confederate Congress passed legislation that authorized a company of engineers for every division in the field; by 1865, the CSA had more engineer officers serving in the field of action than the Union Army. One of the main projects for the Army Corps of Engineers was constructing railroads and bridges. Union forces took advantage of such Confederate infrastructure because railroads and bridges provided access to resources and industry. The Confederate engineers outperformed the Union Army in building fortifications that were used both offensively and defensively, along with trenches that made them harder to penetrate. This method of building trenches was known as the zigzag pattern.

During World War II the USACE program expanded to more than 27,000 military and industrial projects in a $15.3 billion mobilization effort. Included were aircraft, tank assembly, and ammunition plants; camps for 5.3 million soldiers; depots, ports, and hospitals; and the rapid construction of such landmark projects such as the

Mission areas


Warfighting

USACE provides support directly and indirectly to the warfighting effort. They build and help maintain much of the infrastructure that the Army and the Air Force use to train, house, and deploy troops. USACE built and maintained navigation systems and ports provide the means to Deployments of the United States Military, deploy vital equipment and other material. Corps of Engineers Research and Development (R&D) facilities help develop new methods and measures for deployment, force protection, terrain analysis, mapping, and other support. USACE directly supports the military in the battle zone, making expertise available to commanders to help solve or avoid engineering (and other) problems. Forward Engineer Support Teams, FEST-A's or FEST-M's, may accompany combat engineers to provide immediate support, or to reach electronically into the rest of USACE for the necessary expertise. A FEST-A team is an eight-person detachment; a FEST-M is approximately 36. These teams are designed to provide immediate technical-engineering support to the warfighter or in a disaster area. Corps of Engineers' professionals use the knowledge and skills honed on both military and civil projects to support the U.S. and local communities in the areas of real estate, contracting, mapping, construction, logistics, engineering, and management experience. This work currently includes support for rebuilding Iraq, establishing Afghanistan infrastructure, and supporting international and inter-agency services. In addition, the work of almost 26,000 civilians on civil-works programs throughout USACE provides a training ground for similar capabilities worldwide. USACE civilians volunteer for assignments worldwide. For example,

Homeland security

USACE supports the United States' Department of Homeland Security and the Federal Emergency Management Agency (FEMA) through its security planning, force protection, research and development, disaster preparedness efforts, and quick response to emergencies and disasters. The CoE conducts its emergency response activities under two basic authorities — the Flood Control and Coastal Emergency Act (), and the Stafford Disaster Relief and Emergency Assistance Act (). In a typical year, the Corps of Engineers responds to more than 30 Presidential disaster declarations, plus numerous state and local emergencies. Emergency responses usually involve cooperation with other military elements and Federal agencies in support of State and local efforts.


Infrastructure support

Work comprises engineering and management support to military installations, global real estate support, civil works support (including risk and priorities), operations and maintenance of Federal navigation and flood control projects, and monitoring of dams and levees. More than 67 percent of the goods consumed by Americans and more than half of the nation's oil imports are processed through list of deep water ports, deepwater ports maintained by the Corps of Engineers, which maintains more than of commercially navigable channels across the U.S. In both its Civil Works mission and Military Construction program, the Corps of Engineers is responsible for billions of dollars of the nation's infrastructure. For example, USACE maintains direct control of 609 dams, maintains or operates 257 navigation locks, and operates 75 hydroelectric facilities generating 24% of the nation's hydropower and three percent of its total electricity. USACE inspects over 2,000 Federal and non-Federal levees every two years. Four billion gallons of water per day are drawn from the Corps of Engineers' 136 multi-use flood control projects comprising of water storage, making it one of the United States' largest water supply agencies. The 249th Engineer Battalion (Prime Power), the only active duty unit in USACE, generates and distributes prime electrical power in support of warfighting, disaster relief, stability and support operations as well as provides advice and technical assistance in all aspects of electrical power and distribution systems. The battalion deployed in support of recovery operations after 9/11 and was instrumental in getting Wall Street back up and running within a week. The battalion also deployed in support of post-Katrina operations. All of this work represents a significant investment in the nation's resources.

Through its Civil Works program, USACE carries out a wide array of projects that provide coastal protection, flood protection, hydropower, navigable waters and ports, recreational opportunities, and water supply. Work includes coastal protection and restoration, including a new emphasis on a more holism, holistic approach to risk management. As part of this work, USACE is the number one provider of outdoor recreation in the U.S., so there is a significant emphasis on water safety. Army involvement in works "of a civil nature," including water resources, goes back almost to the origins of the U.S. Over the years, as the nation's needs have changed, so have the Army's Civil Works missions. Major areas of emphasis include the following: * Navigation. Supporting navigation by maintaining and improving channels was the Corps of Engineers' earliest Civil Works mission, dating to Federal laws in 1824 authorizing the Corps to improve safety on the Ohio and Mississippi Rivers and several ports. Today, the Corps of Engineers maintains more than of inland waterways and operates 235 locks. These waterways—a system of rivers, lakes and coastal bays improved for commercial and recreational transportation—carry about of the nation's inter-city freight, at a cost per ton-mile about that of rail or that of trucks. USACE also maintains 300 commercial harbors, through which pass of cargo a year, and more than 600 smaller harbors. New locks are needed, according to the Corps and barge shippers, where existing locks are in poor condition, requiring frequent closures for repairs, and/or because a lock's size causes delays for barge tows. * Flood Risk Management. The Engineers were first called upon to address flood problems along the Mississippi river in the mid-19th century. They began work on the Mississippi River and Tributaries Flood Control Project in 1928, and the
Flood Control Act of 1936 The Flood Control Act of 1936, , (FCA 1936) was an Act of the United States Congress signed into law by President Franklin Delano Roosevelt on 22 June 1936. The U.S. Army Corps of Engineers environmental mission has two major focus areas: restoration and stewardship. The Corps supports and manages numerous environmental programs, that run the gamut from cleaning up areas on former military installations contaminated by hazardous waste or munitions to helping establish/reestablish wetlands that helps endangered species survive.USACE Environmental Mission webpage
Some of these programs include Ecosystem Restoration, Formerly Used Defense Sites, Environmental Stewardship, EPA

, Abandoned Mine Lands, Formerly Utilized Sites Remedial Action Program, Base Realignment and Closure, 2005, and Regulatory. This mission includes education as well as regulation and cleanup. Litter and trash cleanups typically occur on Earth Day, National Cleanup Day, National CleanUp Day, and National Public Lands Day; there are also individual or small group TrashTag cleanups. The U.S. Army Corps of Engineers has an active environmental program under both its Military and Civil Programs. The Civil Works environmental mission that ensures all USACE projects, facilities and associated lands meet environmental standards. The program has four functions: compliance, restoration, prevention, and conservation. The Corps also regulates all work in wetlands and waters of the United States. The Military Programs Environmental Program manages design and execution of a full range of cleanup and protection activities: * cleans up sites contaminated with hazardous waste, radioactive waste, or ordnance * complies with federal, state, and local environmental laws and regulations * strives to minimize our use of hazardous materials * conserves our natural and cultural resources The following are major areas of environmental emphasis: * Wetlands and Waterways Regulation and Permitting * Ecosystem Restoration * Environmental Stewardship * Radioactive site cleanup through the Formerly Used Sites Remedial Action Program (FUSRAP) * Base Realignment and Closure (BRAC) * Formerly Used Defense Sites (FUDS) * Support to EPA's Superfund Program See also United States Army Corps of Engineers#Environmental enforcement, Environmental Enforcement below.


Sustainability

The Army adopted a sustainability policy in the early 2000s to make military bases, and the force as a whole, more resilient and less dependent on fossil fuels. Since the US military is one of the world's largest institutional energy consumers, this would have a significant impact on reducing waste, improving efficiency, and ensuring that public resources are used effectively. The Army has developed and adopted its own triple bottom line framework shifting from the traditional "People Planet, and Profit" to "Mission, Community, and Environment". To meet these new sustainability targets, it has implemented regulations such as designing all new projects to meet the Leadership in Energy and Environmental Design, LEED silver standard. Additional regulations are detailed in the Sustainable Design and Development Policy. The 2017 revision to the Sustainable Design and Development Policy outlines the updated goals and requirements the Army established in an effort to successfully complete the sustainability mission. Most of these requirements result in stricter regulations on the planning, design and construction of new projects and major renovations: * Siting and site development * Energy performance and security * Indoor and outdoor water use * Metering, monitoring, and subsystem measurement * Indoor environmental quality * Waste and recyclables management * New and underused technologies * Commissioning and plans for operation Many of these goals fall directly onto USACE, as it oversees most construction and maintenance of Army bases and infrastructure. To embrace the branch’s movement toward sustainability, USACE added sustainability as an overarching mission with several specific focus areas: * Gaining expertise and becoming a leader in industry technology and advancement; primarily in areas surrounding construction and energy to enable high-performance buildings and civil works projects, as well as energy security * Planning and implementing a number of approaches to mitigate the potential environmental changes due to the climate crisis specifically with regard to the nation’s water infrastructure * Focusing on purchases that further the sustainability mission and prioritizing designs/technology that are recycled, bio-based, or benefit the environment * Releasing annual Sustainability Report and Implementation Plans for accountability and to track progress toward achieving energy goals This challenge is not without its difficulties. The first report issued in 2008 showed that 78% of new projects were built to the LEED silver standard (without actually getting the certification) instead of the 100% required. In addition, there was an 8.4% and 32% reduction in energy use intensity and water use, respectively, and a 35% increase in hazardous waste production. Later reports show some improvement toward resilience and sustainability. The 2020 Sustainability Report and Implementation Plan show a further 12% reduction in water use as well as 35% total reduction in energy use intensity since 2003. Future projections show that USACE intends to continue to build on these focus areas and drive down its demands in areas such as fuel, electricity and water.


Operational facts and figures

Summary of facts and figures as of 2007, provided by the Corps of Engineers: * One HQ, 8 Divisions, 2 Provisional Division, 45 Districts, 6 Centers, one active-duty unit, 2 Engineer Reserve Command * At work in more than 90 countries * Supports 159 Army installations and 91 Air Force installations * Owns and operates 609 dams * Owns or operates 257 navigation lock chambers at 212 sites * Largest owner-operator of hydroelectric plants in the US. Owns and operates 75 plants—24% of U.S. hydropower capacity (3% of the total U.S. electric capacity) * Operates and maintains of commercial inland navigation channels * Maintains 926 coast, Great Lakes, and inland harbors * Dredge annually for construction or maintenance * Nation's ''number one provider of outdoor recreation'' with more than 368 million visits annually to 4,485 sites at 423 USACE projects (383 major lakes and reservoirs) * Total water supply storage capacity of * Average annual damages prevented by Corps flood risk management projects (1995–2004) of $21 billion (see "Civil works controversies" below) * Approximately 137 environmental protection projects under construction (September 2006 figure) * Approximately of wetlands restored, created, enhanced, or preserved annually under the Corps' Regulatory Program * Approximately $4 billion in technical services to 70 non-DoD Federal agencies annually * Completed (and continuing work on) thousands of infrastructure projects in Iraq at an estimated cost over $9 billion: school projects (324,000 students), crude oil production , potable water projects (3.9 million people (goal 5.2 million)), fire stations, border posts, prison/courthouse improvements, transportation/communication projects, village road/expressways, railroad stations, postal facilities, and aviation projects. More than 90 percent of the USACE construction contracts have been awarded to Iraqi-owned businesses — offering employment opportunities, boosting the economy, providing jobs, and training, promoting stability and security where before there was none. Consequently, the mission is a central part of the U.S. exit strategy. * The Corps of Engineers has one of the strongest Small Business Programs in the Army—Each year, approximately 33% of all contract dollars are obligated with Small Businesses, Small Disadvantaged Businesses, Service Disabled Veteran Owned Small Businesses, Women Owned Small Businesses, Historically Underutilized Business Zones, and Historically Black Colleges and Universities. Jackie Robinson-Burnette was named the Chief of the Corps' Small Business Program in May 2010. The program is managed through an integrated network of over 60 Small Business Advisors, 8 Division Commanders, 4 Center Directors, and 45 District Commanders.


Environmental protection and regulatory program

The regulatory program is authorized to protect the nation's aquatic resources. USACE personnel evaluate permit applications for essentially all construction activities that occur in the nation's waters, including wetlands. Two primary authorities granted to the Army Corps of Engineers by Congress fall under Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. Section 10 of the Rivers and Harbors Act of 1899 (codified in Chapter 33, Section 403 of the United States Code) gave the Corps authority over Navigability, navigable waters of the United States, defined as "those waters that are subject to the ebb and flow of the tide and/or are presently being used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce." Section 10 covers construction, excavation, or deposition of materials in, over, or under such waters, or any work that would affect the course, location, condition or capacity of those waters. Actions requiring section 10 permits include structures (e.g., piers, wharfs, breakwaters, bulkheads, jetties, weirs, transmission lines) and work such as dredging or disposal of dredged material, or excavation, filling or other modifications to the navigable waters of the United States. The Coast Guard also has responsibility for permitting the erection or modification of bridges over navigable waters of the U.S. Another of the major responsibilities of the Army Corps of Engineers is administering the permitting program under Section 404 of the Federal Water Pollution Control Act of 1972, also known as the
Clean Water Act The Clean Water Act (CWA) is the primary federal law in the United States governing water pollution. Its objective is to restore and maintain the chemical, physical, and biological integrity of the nation's waters; recognizing the responsibiliti ...
. The Secretary of the Army is authorized under this act to issue permits for the discharge of dredged and fill material in waters of the United States, including adjacent wetlands. The geographic extent of waters of the United States subject to section 404 permits fall under a broader definition and include tributaries to navigable waters and adjacent wetlands. The engineers must first determine if the waters at the project site are jurisdictional and subject to the requirements of the section 404 permitting program. Once jurisdiction has been established, permit review and authorization follows a sequence process that encourages avoidance of impacts, followed by minimizing impacts and, finally, requiring mitigation for unavoidable impacts to the aquatic environment. This sequence is described in the section 404(b)(1) guidelines. There are three types of permits issued by the Corps of Engineers: Nationwide, Regional General, and Individual. 80% of the permits issued are nationwide permits, which include 50 general type of activities for minimal impacts to waters of the United States, as published in the Federal Register. Nationwide permits are subject to a reauthorization process every 5 years, with the most recent reauthorization occurring in March, 2012. To gain authorization under a nationwide permit, an applicant must comply with the terms and conditions of the nationwide permit. Select nationwide permits require preconstruction notification to the applicable corps district office notifying them of his or her intent, type and amount of impact and fill in waters, and a site map. Although the nationwide process is fairly simple, corps approval must be obtained before commencing with any work in waters of the United States. Regional general permits are specific to each corps district office. Individual permits are generally required for projects that impact greater than of waters of the United States. Individual permits are required for activities that result in more than minimal impacts to the aquatic environment.


Research

The Corps of Engineers has two research organizations, the Engineer Research and Development Center (ERDC) and the Army Geospatial Center (AGC). ERDC provides science, technology, and expertise in engineering and environmental sciences to support both military and civil/civilian customers. ERDC research support includes: * Dam safety systems * Cartography, Mapping and topography terrain analysis * Infrastructure design, construction, operations and maintenance * Structural engineering * CRREL, Cold-regions science and engineering * Coastal and hydraulic engineering, producing products such as HEC-RAS * Environmental quality, including toxic chemistry of bay mud and other dredge spoils * Geotechnical engineering * Earthquake engineering * High performance computing and information technology AGC coordinates, integrates, and synchronizes geospatial information requirements and standards across the Army and provides direct geospatial support and products to warfighters.

Insignia

The Corps of Engineers branch insignia, the Corps Castle, is believed to have originated on an informal basis. In 1841, cadets at West Point wore insignia of this type. In 1902, the Castle was formally adopted by the Corps of Engineers as branch insignia. The "castle" is actually the Pershing Barracks at the United States Military Academy in West Point, New York. A current tradition was established with the "Gold Castles" branch insignia of General of the Army
Douglas MacArthur Douglas MacArthur (26 January 18805 April 1964) was an American military leader who served as General of the Army for the United States, as well as a field marshal to the Philippine Army. He had served with distinction in World War I, was C ...
, West Point Class of 1903, who served in the Corps of Engineers early in his career and had received the two pins as a graduation gift of his family. In 1945, near the conclusion of World War II, General MacArthur gave his personal pins to his Chief Engineer, General Leif J. Sverdrup. On 2 May 1975, upon the 200th anniversary of the Corps of Engineers, retired General Sverdrup, who had civil engineering projects including the landmark -long Chesapeake Bay Bridge-Tunnel to his credit, presented the Gold Castles to then-Chief of Engineers Lieutenant General William C. Gribble, Jr., who had also served under General MacArthur in the Pacific. General Gribble then announced a tradition of passing the insignia along to future Chiefs of Engineers, and it has been done so since.


Controversies


Civil works

Some of the Corps of Engineers' civil works projects have been characterized in the press as being pork barrel or boondoggle (project), boondoggles such as the New Madrid Floodway Project and the New Orleans flood protection. Projects have allegedly been justified based on flawed or manipulated analyses during the planning phase. Some projects are said to have created profound detrimental environmental effects or provided questionable economic benefit such as the Mississippi River–Gulf Outlet in southeast Louisiana. Faulty design and substandard construction have been cited in the 2005 levee failures in Greater New Orleans, failure of levees in the wake of Hurricane Katrina that caused flooding of 80% of the city of New Orleans. Review of Corps of Engineers' projects has also been criticized for its lack of impartiality. The investigation of levee failure in New Orleans during Hurricane Katrina was sponsored by the American Society of Civil Engineers (ASCE) but funded by the Corps of Engineers and involved its employees. Corps of Engineers projects can be found in all 50 states, and are specifically authorized and funded directly by Congress. Local citizen, special interest, and political groups Lobbying, lobby Congress for authorization and appropriations for specific projects in their area. Senator Russ Feingold and Senator John McCain sponsored an amendment requiring peer review of Corps projects to the Water Resources Development Act of 2006,Feingold, McCain, Coburn Work to Reform Army Corps of Engineers
proclaiming "efforts to reform and add transparency to the way the U.S. Army Corps of Engineers receives funding for and undertakes water projects." A similar bill, the Water Resources Development Act of 2007, which included the text of the original Corps' peer review measure, was eventually passed by Congress in 2007, overriding Presidential veto.


Military construction

A number of Army camps and facilities designed by the Corps of Engineers, including the former Camp O'Ryan in New York State, have reportedly had a negative impact on the surrounding communities. Camp O'Ryan, with its rifle range, has possibly contaminated well and storm runoff water with lead poisoning, lead. This runoff water eventually runs into the Niagara River and Lake Ontario, sources of drinking water to millions of people. This situation is exacerbated by a failure to locate the engineering and architectural plans for the camp, which were produced by the New York District in 1949.


Greenhouse whistleblower suit

Bunny Greenhouse, Bunnatine "Bunny" Greenhouse, a formerly high-ranking official in the Corps of Engineers, won a lawsuit against the United States government in July 2011. Greenhouse had objected to the Corps accepting cost projections from KBR (company), KBR in a no-bid, noncompetitive contract. After she complained, Greenhouse was demoted from her Senior Executive Service (United States), Senior Executive Service position, stripped of her top secret security clearance, and even, according to Greenhouse, had her office booby-trapped with a trip-wire from which she sustained a knee injury. A U.S. District court awarded Greenhouse $970,000 in full restitution of lost wages, compensatory damages, and attorney fees.Davidson, Joe, "A Bittersweet Win for a Whistleblower", ''Washington Post'', 27 July 2011, p. B4.
