What Are USACE’s Civil Works Roles?

USACE’s principal civil works responsibilities are

•

•

•

studying and constructing water resource projects;

•

•

administering certain water-related regulatory authorities; and

managing an estimated $259 billion in water resource assets;

leading emergency response activities for public works and engineering under a National Response

Framework, which guides the national response to all types of disasters and emergencies by describing

principal roles and responsibilities;

operating a credit assistance program for selected nonfederal water resource infrastructure.

USACE’s water resource activities, while multifaceted, focus on improving coastal and inland commercial navigation,

reducing riverine flood and coastal storm damage, and restoring aquatic ecosystems. USACE contracts civilian companies for

most of its design work and project construction.

Who Leads USACE Civil Works?

Chief of Engineers. The Chief of Engineers (who is also the Commanding General of USACE) leads both USACE’s civil

works and its military program. The Chief is often a three-star Army general and is assigned to serve in this role for

approximately four years.

Assistant Secretary of the Army for Civil Works (ASACW). The Secretary of the Army typically has delegated civil

works responsibilities to the ASACW. The ASACW provides civil works policy direction and supervision; the ASACW

position, established in law at 10 U.S.C. §7016, is presidentially appointed and Senate confirmed. The Chief of Engineers is

responsible for executing civil works policies established by the ASACW, consistent with federal law and congressional

direction.

Division and District Commanders. USACE divisions and their subordinate districts execute the day-to-day civil works

program. Military officers command these districts and divisions.

Where Are USACE’s Divisions, Districts, and Employees?

The figure below shows USACE’s civil works division and district locations and boundaries, which are shaped in part by

watershed boundaries. USACE has an estimated 37,000 full-time-equivalent employees (FTEs, approximately 98% of which

are civilians and an estimated 810 of which are military professionals). As of FY2024, 26,000 civilian FTEs work on civil

works activities. Approximately 95% of the civil works FTEs report to district offices, USACE centers and their laboratories

and field offices, or USACE field operating entities.

Have There Been Proposals to Transfer USACE Civil Works?

Proposals to transfer USACE’s civil works authorities to other federal agencies have been raised multiple times over many

decades. Efforts to reorganize or transfer civil works responsibilities may require legislation, depending on the proposed

actions.

What Are Some Reviews of USACE’s Efficiency and Effectiveness?

Congress has requested various reports from the Government Accountability Office, National Academy of Sciences, and

National Academy of Public Administration related to USACE efficiency and effectiveness. Some of these reports are

available; others are in development. Various committees also have held hearings related to the agency’s efficiency and

effectiveness.

T

he U.S. Army Corps of Engineers (USACE), within the Department of Defense (DOD), is

a public engineering organization with civil works and military functions. This report

focuses on USACE’s civil works mission and provides information on the agency’s

military responsibilities for context.

Civil Works Roles

What Are USACE’s Civil Works and Military Roles?

USACE’s principal civil works responsibilities are

•

•

•

•

studying and constructing water resource projects;

managing an estimated $259 billion in water resource assets;1

operating a credit assistance program for selected nonfederal water resource

infrastructure;2 and

administering water-related regulatory authorities (i.e., issuing permits and

permissions).3

USACE’s water resource activities focus principally on improving coastal and inland commercial

navigation, reducing riverine flood and coastal storm damage, and restoring aquatic ecosystems.4

USACE contracts civilian companies for most of its design work and civil works construction

(i.e., USACE often acts as a project and contract manager).

USACE civil works also leads emergency response activities for public works and engineering

under the National Response Framework, which guides the national response to all types of

disasters and emergencies. Much of this work is performed under the Stafford Act (42 U.S.C.

§§5121 et seq.), as assigned to USACE by the Department of Homeland Security’s (DHS’s)

Federal Emergency Management Agency (FEMA). This reimbursable work for USACE is

typically funded out of the Disaster Relief Fund.

Additionally, USACE offers its civil works engineering expertise and services typically on a

reimbursable basis to other federal agencies and other entities under various authorities. Among

Report, p. 32, https://www.publications.usace.army.mil/Portals/76/

FY%2024%20Civil%20Works%20Annual%20Financial%20Report.pdf (hereinafter referred to as USACE, FY2024

Financial Report).

2 In September 2023, USACE completed a rulemaking for the program—the Corps Water Infrastructure Financing

Program. In September 2024, USACE invited selected applicants to complete their loan applications. For more

information, see CRS Insight IN12021, Corps Water Infrastructure Financing Program (CWIFP), by Nicole T. Carter.

3 Section 404 of the Clean Water Act (33 U.S.C. §1344) permits are related to the discharge of dredged or fill material

into waters of the United States. Section 10 Rivers and Harbors Act of 1899 permits are related to the obstruction or

alteration of navigable waters. Section 103 of the Marine Protection, Research, and Sanctuaries Act of 1972, as

amended (33 U.S.C. §1413), relates to permits for the transportation of dredged material for dumping in ocean waters.

If a nonfederal entity is interested in altering a USACE civil works project after construction, the entity generally must

obtain permission from USACE. USACE’s authority to allow alterations to its projects derives from Section 14 of the

Rivers and Harbors Act of 1899, also known as Section 408 (based on its codification at 33 U.S.C. §408). USACE also

administers the Formerly Utilized Sites Remedial Action Program (FUSRAP). Through FUSRAP, USACE remediates

radiological contamination at nonfederal sites used during the early years of the U.S. nuclear weapons program. Neither

FUSRAP nor USACE regulatory activities are addressed in this report.

the other federal agencies that have entered into reimbursable agreements for USACE services

are the DHS, Department of Veterans Affairs, and U.S. Environmental Protection Agency. Most

of this work is executed by USACE’s military programs rather than its civil works structure.

For the military, USACE is an element of the Army’s Engineer Regiment, also known as the

engineer branch. The engineer branch includes soldiers assigned to combat engineer, rescue,

construction, and other specialty units that may be attached to combat units.5 USACE also

supports military construction for the Army, Air Force, and other DOD agencies by providing

engineering, construction, real estate, stability operations, and environmental management

products and services. USACE’s military program also performs reimbursable work through its

International and Interagency Services (IIS). Through IIS, USACE assists foreign governments

and international organizations; state, local, and tribal governments; and other federal agencies.6

What Is the Authorization for USACE’s Civil Works Mission?

USACE has roots as far back as 1775, when the Continental Congress organized an army with a

chief of engineers. The United States Congress first legislatively authorized the President to

establish a separate corps of engineers in 1802 (§26 of the Military Peace Establishment Act,

March 16, 1802; 2 Stat. 137).

The legislative basis of USACE civil works activities has evolved since the mid-1820s, when

legislative references to using the military corps of engineers for public surveys and

improvements first appeared in statute. For example, USACE’s civil works activities began

following the General Survey Act of 1824 (April 30, 1824; 4 Stat. 23), which authorized the

President “to cause the necessary surveys, plans, and estimates to be made of the routes of such

roads and canals as he may deem of national importance, in a commercial or military point of

view, or necessary for the transportation of the public mail,” and to employ USACE officers in

these efforts.7

USACE has no principal law or organic act establishing and defining its suite of civil works

responsibilities; instead, a lengthy set of statutory provisions, which typically reference the

Secretary of the Army, authorizes general or project-specific water resource activities.8 The

Secretary of the Army typically has delegated the civil works responsibilities to an Assistant

Secretary of the Army for Civil Works (ASACW).

5 The two reserve commands provide technical and tactical engineer support to U.S. forces. For more on the 412 th

Theater Engineer Command, see Army, “Army Reserve, 412th Theater Engineer Command,”

7 The Government Accountability Office (GAO) identified selected statutes that have shaped USACE civil works

missions; see GAO, Army Corps of Engineers: Organizational Realignment Could Enhance Effectiveness, But Several

Challenges Would Have to Be Overcome, GAO-1-819, October 2010, Appendix III, https://www.gao.gov/assets/320/

U.S. Army Corps of Engineers Civil Works: FAQs on Organization and Efficiency Reviews

Leadership and Organization

Who Leads USACE Civil Works?

Chief of Engineers. The Chief of Engineers (who is also the Commanding General of USACE)

leads both USACE’s civil works and its military activities. The Chief is often a three-star Army

general and is assigned to serve in this role for roughly four years. The Chief of Engineers is

stationed at USACE headquarters in Washington, DC. The Chief of Engineers delegates some

responsibilities to the Deputy Commanding General for Civil and Emergency Operations and to

the Director of Civil Works.9

Assistant Secretary of the Army for Civil Works. The ASACW, established in law at 10 U.S.C.

§7016, is a presidentially appointed, Senate-confirmed position.10 The ASACW establishes policy

direction and provides supervision over Department of the Army functions relating to all aspects

of USACE’s civil works program.11 The Chief of Engineers is responsible for executing the civil

works policies established by the ASACW, consistent with federal law and congressional

directives.12

Division and District Commanders. Divisions are regional offices that supervise and manage

subordinate districts. The district offices are responsible for the day-to-day execution of the civil

works program. Military officers command USACE districts and divisions; these assignments are

often for two to three years.13

Where Are USACE’s Divisions, Districts, and Employees?

USACE had an estimated 37,000 full-time-equivalent employees (FTEs) in FY2024.14

Approximately 98% are civilians, and an estimated 810 are military professionals. About 26,000

civilian FTEs are working on civil works activities.15 Approximately 95% of the civil works FTEs

9 For more on other USACE leadership positions, see USACE, “Leadership,” https://www.sac.usace.army.mil/Media/

Images/igphoto/2001853112/.

10 The Assistant Secretary of the Army for Civil Works (ASACW) position was created by Section 211 of the Flood

Control Act of 1970 (P.L. 91-611). The position was reaffirmed in 1986 in Section 501 of P.L. 99-422 (10 U.S.C.

§7016), which states that the ASACW “shall have as his principal duty the overall supervision of the functions of the

Department of the Army relating to programs for conservation and development of the national water resources,

including flood control, navigation, shore protection, and related purposes.” For more on the Office of the ASACW, see

ASACW, “Leaders,” https://www.army.mil/asacw#org-about.

11 A 1965 report recommended replacing the Secretary of the Army’s Special Assistant for Civil Works with the

ASACW position with primary responsibilities for the civil works mission, while maintaining cognizance of

interrelated aspects of the agency’s civil works and military missions (Civil Works Study Board, A Report to the

Secretary of the Army on the Civil Works Program of the Corps of Engineers, January 1965, p. 18). As part of the

ASACW’s civil works responsibilities, the ASACW provides oversight over interagency and international technical

and managerial assistance agreements pursuant to 33 U.S.C. §2323a for work on problems related to water resources,

infrastructure development, and environmental protection provided typically on a reimbursable basis.

12 The Chief of Engineers reports to the Chief of Staff of the Army on Engineer Regiment matters, and follows the

policy guidance and is under the supervision of the Assistant Secretary of Defense for Energy, Installations, and

Environment on many military construction matters.

13 Most USACE districts have a colonel as the commander, although a few have a lieutenant colonel as the commander.

14 USACE does not track how many of the 37,000 employees work on both military and civil works activities (email to

CRS from USACE, December 20, 2024).

15 USACE, FY2024 Financial Report, p. 12. Earlier financial reports indicate the number of civil works civilian

employees as 25,000 in FY2023; 24,000 in FY2022; and 24,000 in FY2016 and FY2015. Military professionals

field operating entities. Figure 1 shows the boundaries of the divisions and districts, and the

locations of the location of the division and district offices. USACE’s civil works district and

division boundaries are shaped in part by watershed boundaries.

The majority of USACE’s nine divisions (also referred to as major subordinate commands) and

44 districts serve both civil and military functions.

•

•

For civil works, USACE has authority to work in U.S. states and selected

territories. This work is managed by USACE headquarters, eight divisions, and

39 districts (including a Caribbean District in San Juan, PR, established in

2024).17

USACE’s military work is supported by eight divisions, including the

Transatlantic division, and more than half of the 44 districts.

FY%2019%20CW%20Audit%20Opinion%20and%20Financials.pdf.

16 In GAO-1-819 (pp. 49-50), Table 5 provides information on the distribution of USACE’s staff from FY2000 through

FY2009 by division and district. According to USACE, there are 207 civil work full-time-equivalent employees at the

headquarters office (email to CRS from USACE, December 20, 2024).

17 Of the 39 districts, 20 are dedicated to civil works (i.e., no military role) and 19 are reported by USACE as having

civil or military roles (email to CRS from USACE, December 20, 2024). There is USACE information indicating that

the Caribbean district is only civil works, and other USACE sources that indicate the district also may support military

programs, as well (e.g., interagency support). According to USACE, the Europe district conducts military program

activities and offers international and interagency services; it is not included in the 39 districts that support civil works.

Rehabilitation Program, which supports the repair of damaged levees. For more, see USACE, U.S. Army Corps of

Engineers Levee Portfolio Report, March 2018.

What Is USACE’s Role in Domestic Emergency Response?

The National Response Framework guides the national response to all types of disasters and

emergencies by describing principal roles and responsibilities. Under the National Response

Framework, USACE is the lead for public works and engineering in responding to domestic

emergencies and disasters. In this role, USACE provides technical assistance, engineering

support, and construction management, as well as emergency contracting and emergency power

and repair for critical facilities. The agency also assists in monitoring, stabilizing, or demolishing

damaged structures and provides technical assistance in clearing, removing, and disposing of

debris and in establishing overland and water routes into affected areas. Often FEMA gives

USACE public works and engineering mission assignments, pursuant to the Stafford Act. At

times, emergency response assignments have called on both USACE military (e.g., 249th Prime

Power Battalion and military contracting authorities) and civil works authorities, personnel, and

expertise.28

Additionally, Congress has provided the Secretary of the Army and the Chief of Engineers some

emergency authorities for natural disasters (33 U.S.C. §701n, including for flood-fighting and

emergency water supplies in certain circumstances).

According to USACE, the agency responded to 21 events with 1,500 personnel in FY2023.29 In

FY2024, USACE responded to 27 floods and coastal storms with 2,000 personnel.30 Responses

28 For example, the Federal Emergency Management Agency tasked USACE with performing initial electric power

repairs in Puerto Rico following Hurricane Maria in 2017, which illustrates how USACE at times has been tasked with

significant engineering assignments as part of federal emergency response activities. For another example, as part of

urban search and rescue efforts, USACE may deploy various specialized civil and military teams and general-purpose

troops during structural collapse incidents and other disaster response missions. For more information, see USACE,

“Urban Search and Rescue Program,” https://www.usace.army.mil/Missions/Emergency-Operations/NationalResponse-Framework/Urban-Search-and-Rescue/.

as wildfires in Hawaii in 2023 and Francis Scott Key Bridge navigation channel wreckage

removal in 2024. USACE indicates that its FEMA mission-assigned tasks totaled 215 in FY2023

at a cost of $684 million and 74 in FY2024 at a cost of $824 million.31

Funding and Projects

What Has Been USACE’s Recent Civil Works Funding?

USACE reports on its annual and supplemental funding and its reimbursable funding for each

fiscal year in its annual financial reports. Figure 3 shows reported funding for FY2017 through

FY2024.

U.S. Army Corps of Engineers Civil Works: FAQs on Organization and Efficiency Reviews

How Many Civil Works Projects Does USACE Plan and Construct?

For civil works, Congress has authorized USACE to produce studies and other planning

documents (e.g., preconstruction engineering and designs, reevaluations) and to conduct

construction projects. The cost of the authorized activities exceed the funds Congress has

appropriated the agency to perform these activities.32 Therefore, USACE’s federal appropriations

are often the factor limiting which plans and construction activities are performed.

In FY2023 and FY2024, USACE had annual, supplemental, and reprogrammed supplemental

appropriations available to accomplish work on civil works plans and construction projects.33

According to USACE financial reports, in FY2023 the agency had $10.890 billion in annual

($8.660 billion) and supplemental appropriations ($2.230 billion).34 In FY2024, it had $9.731

billion in annual appropriation ($8.681 billion) and supplemental appropriation ($1.050 billion;

$1.000 billion of which was for operation and maintenance and $50 million of which was for

construction of shore protection projects); in FY2024, it also had repurposed prior year

Figure 4 shows the number of USACE planning and construction activities that were underway

in FY2023 and FY2024 using annual appropriations, based on information provided in USACE

financial reports. The figure also includes information on construction projects funded with

supplemental appropriations in both fiscal years. Figure 4 illustrates that USACE is studying

more projects than it is constructing with annual appropriations and shows the role supplemental

funds have played in advancing construction projects. The counts shown in Figure 4 do not

include agency projects of limited scope and cost performed under USACE’s continuing

authorities programs (CAP),36 periodic nourishments of sand for certain coastal storm damage

reduction and erosion projects, assistance for nonfederal environmental infrastructure,37 or

Proposals to Transfer Authority

Have There Been Proposals to Transfer USACE Civil Works

Authorities?

Proposals to transfer USACE’s civil works authorities to other federal agencies have been raised

multiple times over many decades. Efforts to transfer USACE civil works responsibilities and

other reorganization efforts may require legislation, depending on the proposed actions.

Previous proposals to transfer USACE civil works activities (e.g., to the Department of the

Interior) have focused on the potential efficiencies of having USACE water resource activities

within the same organization as other water, natural resource, transportation, or land management

activities. In 2018, the Trump Administration proposed moving USACE’s civil works navigation

activities from DOD to the Department of Transportation;38 the proposal indicated that all other

USACE civil works activities would be transferred to the Department of the Interior.39

Some proposals have focused on studying the potential effects of a transferring USACE civil

works authorities. For example, in Section 1102 of the Water Resources Development Act of

2018 (WRDA 2018; Title I of P.L. 115-270), Congress directed the Secretary of the Army to enter

into an agreement with the National Academy of Sciences to convene an expert committee to

study (1) USACE’s ability to carry out its statutory missions and responsibilities, (2) the potential

effects of transferring functions from DOD, and (3) USACE’s project delivery processes.40

For several years after 2018, enacted Energy and Water Development appropriations acts

prohibited the use of USACE civil works funds for the reorganization or transfer of the agency’s

civil works functions or authorities to another department or agency.41

For more on the responses and concerns raised in the context of past proposals to transfer USACE

civil works authorities, see box “Responses to Previous Authority-Transfer Proposals and the

2018 President Trump Proposal.”

Responses to Previous Authority-Transfer Proposals and the 2018

President Trump Proposal

Various past proposals to transfer U.S. Army Corps of Engineers (USACE) civil works authorities to other federal

agencies focused on the potential efficiencies of consolidating federal water, natural resource, transportation, and

land management activities. Part of the opposition to previous proposals, especially in the late 1940s, included that

USACE’s water resource projects and flood-fighting and disaster response functioned as peacetime training and

38 U.S. Executive Office of the President, Office of Management and Budget (OMB), Delivering Government Solutions

in the 21st Century: Reform Plan and Reorganization Recommendations, June 21, 2018. A 2012 GAO study that

examined the roles of USACE and the Department of Transportation for port-related infrastructure found limited

coordination and concluded that national freight and maritime system-wide investments would benefit from greater

USACE involvement (GAO, Maritime Infrastructure: Opportunities Exist to Improve the Effectiveness of Federal

Efforts to Support the Marine Transportation System, GAO-13-80, November 13, 2012).

39 Separate House and Senate authorizing committees have jurisdiction over USACE civil works and DOI water

resource development activities in the U.S. West managed by the Bureau of Reclamation.

40 The study authority specified that the Secretary may not implement the study’s finding unless expressly authorized

by Congress.

41 For example, see Section 107 of Division D, P.L. 117-328, which stated, “None of the funds made available by this

Act or any other Act may be used to reorganize or to transfer the Civil Works functions or authority of the Corps of

Engineers or the Secretary of the Army to another department or agency.” Similar language was not part of FY2024

enacted appropriations for USACE civil works.

work for military engineers. A mid-1980s proposal by the Office of Management and Budget to merge the Bureau

of Reclamation and USACE was not supported by the Secretaries of the Interior and Defense, reportedly because

the two agencies’ programs had little overlap and insufficient savings from merging the agencies.

In 2018, the Trump Administration proposed moving USACE’s civil works navigation activities from the

Department of Defense to the Department of Transportation (DOT). The 2018 Trump Administration proposal

raised uncertainties about what entities would be responsible for maintaining existing navigation infrastructure and

managing new investments, especially for waterways that traverse multiple states. At present, DOT primarily funds

transportation through grants and loans to states, local governments, and public-private partnerships and generally

does not own and operate transportation infrastructure (with the exception of the Federal Aviation

Administration’s ownership of air traffic facilities and equipment). When DOT was created in the mid-1960s, the

Lyndon B. Johnson Administration specifically chose not to propose moving USACE navigation functions to DOT

because of the multipurpose nature of water resource projects. The 2018 Trump Administration proposal

indicated that all USACE civil works activities other than navigation would be transferred to the Department of

the Interior (DOI). Transfer of much of USACE to DOI could have shifted DOI to become a department with

water resource assets across the country, multiple water-related regulatory authorities, and a significant

emergency response role. Congress did not adopt the 2018 Trump Administration’s proposal for transferring

USACE’s civil works responsibilities, and the FY2023 appropriations act prohibited funding of a transfer or

reorganization of these responsibilities.

Efficiency and Effectiveness Reviews

What Are Some Examples of Reviews of USACE’s Efficiency and

Effectiveness?

In 2012, CRS produced a report on USACE’s fiscal challenges that described recommendations

from various expert and government sources on how to improve the agency’s civil works

activities.42 Other government agencies have produced various reports on the topic since then.

Some of the published reports that broadly cover USACE’s efficiency and effectiveness include

the following:

The Army’s Engineer Inspector General also conducts audits and investigations related to

USACE activities.47 The Chief of Engineers, as the Commanding General of USACE, reportedly

directs the Engineer Inspector General’s office to conduct investigations on specific topics (e.g.,

logistics, teleworking).48

In addition, Congress has regularly held hearings on USACE where some committee members

have raised questions of efficiency and effectiveness. Examples include the Senate Committee on

Environment and Public Works’ November 29, 2023, hearing on Stakeholder Feedback on

USACE Project Partnership Agreements and its October 6, 2021, hearing on The U.S. Army
