Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
Summary
The U.S. Army Corps of Engineers undertakes activities to maintain navigable channels, reduce
flood and storm damage, and restore aquatic ecosystems. Congress directs the Corps through
authorizations, appropriations, and oversight of its studies, construction projects, and other
activities. This report summarizes congressional authorization and appropriations processes for
the Corps. It also discusses agency activities under general authorities.
Omnibus Authorization Legislation. Congress generally authorizes numerous Corps site-
specific activities and provides policy direction in an omnibus Corps authorization bill, typically
called the Water Resources Development Act (WRDA) or more recently the Water Resources
Reform and Development Act of 2014 (WRRDA 2014; P.L. 113-121). During the 114th Congress,
the Corps will continue development of implementation guidance for the roughly 150 provisions
in WRRDA 2014. The act called for the agency to submit an annual report of potential and
publicly submitted study and project authorization by February 2015. This annual report, along
with completed Corps studies, may form the basis for discussion of subsequent authorization
legislation. As of January 2015, at least seven projects with federal costs estimated at $1.3 billion
have completed their feasibility reports since WRRDA 2014 enactment and have been
recommended for construction by the Chief of Engineers.
Agency Appropriations. Federal funding for Corps civil works activities is provided in annual
Energy and Water Development appropriations acts or supplemental appropriations acts. Annual
Corps civil works appropriations have ranged from $4.5 billion to $5.5 billion during the last
decade. An increasing share of the agency’s appropriations has been used for operations and
maintenance. Another long-term trend has been increasing emergency supplemental
appropriations for the agency. In part because of competition for funds and because Corps
authorizations outpace appropriations, many authorized activities have not received
appropriations.
Few of the activities authorized by WRRDA 2014 were funded in FY2015 due in part to the
timing of the authorization and appropriations bills. Which WRRDA 2014 provisions should be
funded in FY2016 is likely to be the subject of stakeholder and congressional attention. There is a
backlog of more than 1,000 authorized studies and construction projects. In recent years, few new
studies, new construction activities, and new programs have been in either the President’s budget
request or enacted appropriations.
Standard Project Development. The standard process for a Corps project requires two separate
congressional authorizations—one for investigation and one for construction—as well as
appropriations. The investigation phase starts with Congress authorizing a feasibility study.
Congressional authorization for construction is based on the feasibility study. For most activities,
Congress requires a nonfederal sponsor to share some portion of study and construction costs.
These cost-sharing requirements vary by the type of project. For many project types (e.g., levees),
nonfederal sponsors are responsible for operation and maintenance once construction is complete.
Other Corps Activities and Authorities. Although most projects are developed under the
standard project development process, there are exceptions. Congress has granted the Corps some
general authorities to undertake some studies, small projects, technical assistance, and emergency
actions such as flood-fighting, repair of damaged levees, and limited drought assistance.
Additionally, the Corps conducts emergency response actions directed by the Federal Emergency
Management Agency.

Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
Army Corps of Engineers
The U.S. Army Corps of Engineers is an agency in the Department of Defense with both military
and civil works responsibilities. Under its civil works program, it plans, builds, operates, and
maintains a wide range of water resource facilities. Its civil works responsibilities are principally
to support navigation, reduce flood and storm damage, and protect and restore aquatic
ecosystems.1 The agency attracts congressional attention because its projects can have significant
local and regional economic benefits and environmental effects.
The civil works program is led by a civilian Assistant Secretary of the Army for Civil Works. A
military Chief of Engineers oversees the Corps’ civil and military operations and reports on civil
works matters to the Assistant Secretary for Civil Works. A Director of Civil Works reports to the
Chief of Engineers. The Corps’ civil works responsibilities are organized under eight divisions
that are further divided into 38 districts.2
This report provides an overview of the Corps civil works program, including congressional
authorization and appropriations. The report also covers the standard project development process
for Corps projects and other Corps activities and authorities.
Corps Authorizations
The Corps must be authorized to undertake an activity; the authorization can be project-specific,
programmatic, or general.3 While necessary, authorizations are usually insufficient for a Corps
study or construction project to proceed; action on an authorization requires funding.
In recent decades, Congress has legislated on most Corps authorizations in omnibus Water
Resources Development Acts (WRDAs).4 Authorizations at times have appeared in
appropriations or supplemental appropriations legislation, especially in years when a WRDA is
not enacted. If authorizations are included in an appropriations bill, they could be subject to a
point of order on the floor for being non-germane.
WRDAs, or more recently the Water Resources Reform and Development Act of 2014 (WRRDA
2014; P.L. 113-121), authorize Corps studies, projects, and programs and establish policies for
Corps civil works activities (e.g., nonfederal cost-share requirements). A WRDA is not a
1 Other Corps responsibilities include flood emergency and natural disaster response, such as flood-fighting, repair to
damaged levees, and emergency water supply assistance. Congress also has authorized Corps participation in select
environmental infrastructure projects (e.g., municipal water and wastewater treatment systems) and other nontraditional
activities. The Appendix provides more on the evolution of Corps civil works missions and authorities.
2A division map and district links are available at http://www.usace.army.mil/about/Pages/Locations.asp.
3 While most Corps authorizations are in legislation, many studies are undertaken under other authorities. Authorizing
committees can authorize a study to reexamine a geographic area previously studied by the Corps for a similar purpose;
this authority derives from §4 of the Rivers and Harbors Act of 1913 (37 Stat. 801, 33 U.S.C. §542). Similarly, some
studies reviewing operations of completed projects proceed under general study authorizations without congressional
action; this is pursuant to §216 of the Flood Control Act of 1970 (P.L. 91-611, 33 U.S.C. §549a).
4 WRDAs are distinguished from each other by referencing the year of enactment; that is, WRDA 1986 refers to the act
passed in 1986. The authorizing committee generally develops a bill for introduction by the chairperson; alternatively,
the Administration can propose a bill for congressional consideration. Once a committee of jurisdiction—the House
Transportation and Infrastructure Committee or the Senate Environment and Public Works Committee—decides to
consider a WRDA or similar legislation, Members of Congress often may request inclusion of particular provisions. If
the Administration proposes a WRDA, Congress generally receives the proposal at the same time as the President’s
budget. More than a decade has passed since the last Administration-proposed WRDA bill.

reauthorization bill but rather an authorization bill. That is, WRDAs generally authorize new
activities that are added to the pool of existing authorized activities. Most project-specific
authorizations in WRDAs fall into three general categories: project studies, construction projects,
and modifications to existing project authorizations. WRDAs also have deauthorized projects and
established deauthorization processes.
WRDAs do not appropriate funds for activities; project funding is provided typically through the
annual appropriations process for the agency. That is, congressional authorizations make certain
projects and activities eligible for receiving federal funding. While use of monies from trust funds
associated with Corps activities generally requires congressional appropriations action (i.e., the
funds are on-budget), a WRDA may be a legislative vehicle for altering trust fund collections and
disbursement policies and procedures.
Beginning in 1986, a biennial WRDA cycle was loosely followed for a number of years. WRDAs
were enacted in 1988 (P.L. 100-676), 1990 (P.L. 101-640), 1992 (P.L. 102-580), 1996 (P.L. 104-
303), 1999 (P.L. 106-53), 2000 (P.L. 106-541), and 2007 (P.L. 110-114). WRDA 1986 marked the
end of a stalemate between Congress and the executive branch regarding authorizations. It
resolved long-standing disputes related to cost sharing, user fees, and environmental
requirements. Prior to 1986, disputes over these and other matters had largely prevented
enactment of major civil works legislation since 1970. Biennial authorizations were resumed after
WRDA 1986 to avoid long delays between the planning and execution of projects and so that
Congress could review proposed projects on a regular basis. Pressure to authorize new projects,
increase authorized funding levels, and modify existing projects is often intense, thus prompting a
fairly regular biennial consideration of WRDA, although enactment has been less consistent.
Controversial project authorizations and disagreements over the need for and direction of changes
to the way the Corps plans, constructs, and operates projects contributed to WRDA bills not being
enacted in the 107th, 108th, and 109th Congresses. The 110th Congress enacted WRDA 2007 in
November 2007, overriding a presidential veto. Earmark restrictions complicated WRDA
enactment in the 111th and 112th Congresses. WRRDA 2014, which was enacted on June 10, 2014,
overcame these concerns to authorize 34 construction projects. It also altered processes and
authorization for project delivery, including expanded opportunities for nonfederal entities to lead
projects and for innovative financing.5
During the 114th Congress, the agency will continue development of implementation guidance for
the roughly 150 provisions in WRRDA 2014. As of late January 2015, the Corps had completed
guidelines for roughly 5% of the provisions. WRRDA 2014 called for the agency to submit an
annual report of potential and publicly submitted study and project authorizations by February
2015. This annual report, along with completed Corps studies, may form the basis for discussion
of subsequent authorization legislation. As of January 2015, at least seven projects with federal
costs estimated at $1.3 billion have completed their feasibility reports since WRRDA 2014
enactment and have been recommended for construction by the Chief of Engineers.
Corps Appropriations
The Corps is typically funded through congressional appropriations provided in the annual
Energy and Water Development appropriations bill. Because the rate of Corps authorizations
exceeds the rate of the agency’s annual appropriations, only a subset of authorized activities

Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
typically are included in the President’s budget request and eventually funded by enacted
appropriations. This situation results in competition for funds among authorized activities during
the budget and appropriations processes. To concentrate limited resources and move ongoing
projects toward completion, budget requests by the George W. Bush and Obama Administrations
have focused funding on projects near completion and limited new studies and projects. Both
Administrations also have focused funds on projects within the Corps’ primary missions of flood
and storm damage reduction, navigation, and aquatic ecosystem restoration.
In most years, the President’s budget request for the Corps is below the agency’s final enacted
appropriations. Over the last decade, enacted annual Corps civil works appropriations (excluding
supplemental appropriations) have remained steady or increased slightly, ranging from $4.5
billion to $5.5 billion, whereas the President’s request typically has been less than the final
enacted am
ount. Most recently, Congress appropriated $5.45 billion to the Corps for FY2015 in
P.L. 113-76. Recent trends in Corps budget requests and enacted appropriations are shown below
in Figure 1. The President’s civil works request for FY2016 is $4.73 billion.

Note: Data does not include supplemental appropriations.
Traditional Account Structure and Budgeting Approach
The President’s budget request for the Corps typically includes funding requests at both the
account level (i.e., investigation, construction, operations, and maintenance) and by business line
(i.e., types of activities such as navigation and flood and coastal storm damage reductions). It also
includes project-specific funding levels for those projects proposed for funding. The executive
branch justifies decisions of which projects to fund and at what level through a number of
measures, including benefit-cost ratios and other measures that are outlined in Corps budget
Congressional Research Service

development guidance each year.6 Descriptions of proposed work are included in budget
justifications that are published by the Corps after the release of the President’s budget request.7
Congress generally provides money to the Corps in appropriations laws at the account level.
Accompanying congressional reports, which are sometimes incorporated into law by reference,
often identify specific Corps projects to receive appropriated funds. With the heightened attention
to and restrictions on congressionally directed spending, since FY2010 the projects identified in
these reports have been limited largely to the projects included in the President’s budget request,
and new line items have not been added by Congress at the project level. Congressional action on
Corps appropriations has generally been limited to (1) alteration of the amounts requested for
individual projects and at the account level in the President’s request; and (2) provision of
additional funding for various types of Corps activities within each account that Congress views
as having received an inadequate funding request (see below section, ““Additional Funding”
Categories”).
The two largest Corps accounts are Construction and Operations and Maintenance (O&M), which
together account for the majority of the agency’s funding. The O&M account has made up a
growing portion of the Corps funds over this time, whereas the budget for the Construction
account, including “new start” construction projects, has been reduced. This shift is consistent
with recent efforts by the Administration and Congress to limit funding for new activities and
instead focus on completing existing projects and efforts to address aging infrastructure issues.
Recent enacted appropriation bills for FY2014 and FY2015 have lifted earlier bans on new
construction starts and allowed the agency to initiate a specified number of Corps new start
studies and projects. However, numerous projects have yet to be initiated.
Two congressionally authorized trust funds are administered by the Corps and require annual
appropriations. The Harbor Maintenance Trust Fund (HMTF) and the Inland Waterways Trust
Fund (IWTF) support cost-shared investments in federal navigation infrastructure for harbors and
inland waterways, respectively. Maintenance funding for harbor-related maintenance activities is
funded in part from the HMTF. This trust fund receives revenues from taxes on waterborne
commercial cargo imports and on cruise ship passengers at federally maintained ports. Similarly,
roughly half of inland waterways construction appropriations are from the IWTF, which receives
the proceeds of a fuel tax on barge fuel for vessels engaged in commercial transport on designated
waterways. Although the HMTF has a large surplus balance, the IWTF faces revenue shortages
that may prevent it from maintaining historical levels of expenditures. Both trust funds have
recently received attention from Congress and have been addressed in authorizing legislation.8
“Additional Funding” Categories
Roughly 85% of the Corps budget is typically for geographically specified studies or projects. In
addition to specific projects identified for funding in the President’s budget, for decades Congress
annually identified during the discretionary appropriations process many additional Corps
projects to receive funding (e.g., dredging of low- and medium-use harbors at specific locations).9

and Issues for Congress, by Charles V. Stern and CRS Report R43222, Harbor Maintenance Finance and Funding, by
John Frittelli.
9 While congressional earmarks make up a relatively small percentage of most agency budgets, a significant number of
Corps projects historically received additional funding from Congress for construction or operational expenditures.
Congressional Research Service

Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
In the 112th Congress, site-specific project line items added by Congress (i.e., earmarks or
congressionally directed spending) became subject to House and Senate earmark moratorium
policies. As a result, Congress generally has not added funding at the project level since FY2010.
In lieu of the traditional project-based increases, Congress has included “additional funding”
categories for various types of Corps projects (e.g., additional funding for ongoing maintenance
of small, remote, or subsistence harbors), along with directions and limitations on the use of these
funds. The Corps has been directed to report back to Congress in annual work plans on how these
funds are to be allocated at the project level.10 Congress continued the practice of adding funding
for various categories of Corps work within the agency’s major accounts in in FY2015, providing
over $1 billion in additional funding for various categories of Corps projects in the Investigations,
Construction, O&M, and Mississippi River and Tributaries accounts.
Supplemental Appropriations
Recent significant emergency supplemental appropriations for the agency are an additional
consideration in the context of Corps appropriations. From 1987 to 2014, Congress appropriated
$32.2 billion in supplemental funding to the Corps.11 Of this funding, $30.8 billion came through
supplemental appropriations acts enacted since 2003. This funding was approximately half of the
amount provided to the Corps for regular appropriations through FY2014 ($61.3 billion). The
majority of these supplemental appropriations funded Corps flood-fighting activities, repairs, and
storm damage infrastructure investments (e.g., activities in response to the 2005 hurricanes,
including Hurricane Katrina; 2008 Midwest floods; and 2011 Missouri and Mississippi floods). In
January 2013, Congress provided the Corps with $5.3 billion in supplemental appropriations to
respond to Hurricane Sandy’s landfall in 2012. Much of this funding is expected to be available
for construction projects over a multiyear horizon. For a discussion of Corps supplemental
appropriations, see CRS Report R42841, Army Corps Supplemental Appropriations: Recent
History, Trends, and Policy Issues, by Charles V. Stern and Nicole T. Carter.
Standard Corps Project Delivery Process
The congressional authorization and the appropriations processes are critical steps in a multi-step
process to deliver a Corps project. This section describes the standard study and construction
process for most Corps projects, and it provides some exceptions to the standard process. The
standard process consists of the following basic steps (see also Table 1):
• Study authorization is obtained in WRDA, other legislation, or a committee
resolution.
• The Corps performs a preliminary analysis using appropriated funds.12
• The Corps performs a feasibility study if the preliminary analysis is favorable
and funds are appropriated.
• Construction authorization is pursued. The Corps can perform preconstruction
engineering and design while construction authorization is being pursued.
10 Recent Corps Work Plans are available at http://www.usace.army.mil/Missions/CivilWorks/Budget.aspx.
11 This includes $5.3 billion in supplemental funds provided for response and recovery related to Hurricane Sandy in
P.L. 113-2.
12 Section 1002 of WRRDA 2014 consolidated the contents of the Corps preliminary analysis (which previously was
reported as a separate reconnaissance study) and its feasibility study.
Congressional Research Service
5
Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
• Congress authorizes construction in WRDA or other legislation, and the Corps
constructs the project if funds are appropriated.
The process is not automatic. Appropriations are required to perform studies and undertake
construction; that is, congressional study and construction authorizations are necessary but
insufficient for the Corps to pursue a project. For most activities, the Corps also needs a
nonfederal sponsor to share the study and construction costs. Nonfederal sponsors generally are
state, tribal, county, or local agencies or governments. Although sponsors typically need to have
some taxing authority, some Corps activities can be cost-shared with nonprofit and other entities.
Since WRDA 1986 (P.L. 99-662), nonfederal sponsors are responsible for a significant portion of
the financing of studies, construction, and operation and maintenance (O&M) of most projects.
Generally, projects take longer than the times shown to complete the steps shown in Table 1
because they have to wait for appropriations or congressional authorizations. The Corps has
roughly 200 active feasibility studies; a number are completed or nearing completion.
WRRDA 2014 expanded and consolidated the authorities for nonfederal entities to both perform
studies and construct projects (or elements of projects) that would typically be undertaken by the
Corps and for the cost of these studies and construction to be shared by the federal government
largely as if they had been performed by the Corps. While nonfederal study and project delivery
may increase under these authorities, the process described herein is the standard Corps process
in which the Corps is the manager of the study and project, and the nonfederal sponsor
contributes a portion of the costs and associated real estate, easements, etc.

Study Authority to Initiate a Corps Project
A Corps project starts with a study of the water resource issue and alternatives to address it. The
purpose of the Corps study process is to inform federal decision makers on whether there is a
Congressional Research Service
6
Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
federal interest in authorizing a Corps construction project. The Corps generally requires two
types of congressional action to initiate a study—study authorization and then appropriations.13
Interest in Corps assistance with a water resource need often originates with a request from a
local or state government entity or community, business, or other local interests.
Once a study is authorized, appropriations are sought through the annual Energy and Water
Development appropriations acts. Within the Corps, projects are largely planned at the district
level and approved at the division and Corps headquarters. Early in the study process, the Corps
assesses the level of interest and support of nonfederal entities that may be potential sponsors. It
also investigates the nature of the water resources problem and assesses the federal government’s
interest.
Feasibility Study and Construction Authorization
If a nonfederal sponsorship is secured and the Corps recommends proceeding, a feasibility study
begins. The cost of the feasibility study (including related environmental studies) is split equally
between the Corps and the nonfederal project sponsor, as shown in Table 1. The objective of the
feasibility study is to formulate and recommend solutions to the identified water resources
problem. During the first few months of a feasibility study, the local Corps district formulates
alternative plans, investigates engineering feasibility, conducts benefit-cost analyses, and assesses
environmental impacts under the National Environmental Policy Act of 1969 (NEPA, 42 U.S.C.
§4321).14 The evaluation of federal water resources projects, including Corps activities, is
governed by the 1983 Principles and Guidelines for Water and Related Resources
Implementation Studies, written by the Water Resources Council, and policy direction provided in
WRDA bills and other enacted legislation.15 An important outcome of the feasibility analysis is
determination of whether the project warrants further federal investment (i.e., whether it has
sufficient national economic development benefits).
13 If the Corps has performed a study in the geographic area before, a new study also can be authorized by a resolution
(known commonly as a survey resolution) of either the House Transportation and Infrastructure Committee or the
Senate Environment and Public Works Committee. To be eligible for a resolution authorization, the new study must
stay within the scope of the authorization of the original, completed report. If the Corps has not previously investigated,
Congress needs to authorize the study in legislation, typically WRDA. To request a study’s inclusion in a resolution, a
Member of Congress may send a letter to the chairman of the House Transportation and Infrastructure Committee or
the Senate Environment and Public Works Committee. The number of studies authorized by resolution varies by
Congress. The 108th Congress authorized 63 studies via survey resolutions; the 109th Congress authorized 29. More
recent Congresses have not used Corps study resolutions.
14 CRS Report R43209, Environmental Requirements Addressed During Corps Civil Works Project Planning:
Background and Issues for Congress, by Linda Luther, discusses in detail how the Corps study process is combined
with its NEPA compliance process.
15 The Administration has updated the Principles and Guidelines; information on the revision process is available at
http://www.whitehouse.gov/administration/eop/ceq/initiatives/PandG. In March 2013, Administration’s Council on
Environmental Quality (CEQ) released updated principles and guidelines that included a final set of principles and
requirements that established broad principles for federal water resources investments across a number of agencies
specified therein. In December 2014, the Administration released final interagency guidelines that take effect 180 days
after their publication in the Federal Register, which was Dec. 24, 2014. The explanatory statement accompanying P.L.
113-235, which provided the Corps FY2015 appropriations, however, included the following language and other
direction to the Corps on these documents: “No funds provided to the Corps of Engineers shall be used to develop or
implement rules or guidance to support implementation of the final Principles and Requirements for Federal
Investments in Water Resources released in March 2013. The Corps shall continue to use the document dated March
10, 1983, and entitled ‘Economic and Environmental Principles and Guidelines for Water and Related Land Resources
Implementation Studies’ during the fiscal year period covered by the Energy and Water Development Appropriations
Act for 2015.”
Congressional Research Service

Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
The feasibility phase ends when the Chief of Engineers signs a final recommendation on the
project, known as the Chief’s Report. The Corps sends an “informational copy” of the Chief’s
Report to Congress when it transmits the report to the Assistant Secretary and the Office of
Management and Budget (OMB). Since the mid-1990s, Congress has authorized a significant
number of projects based on Chief’s Reports, prior to the projects receiving a full review by the
Assistant Secretary and OMB.16
Once construction is authorized and funds appropriated, the Corps typically functions as the
project manager; that is, Corps staff typically are responsible for implementing construction.
While some construction may be performed by Corps personnel and equipment, the majority of
work is contracted out to private engineering and construction contractors. Post-construction
ownership and operations responsibilities depend on the type of project. When construction is
complete, the Corps may own and operate the constructed project (e.g., navigation projects), or
ownership may transfer to the nonfederal sponsor (e.g., most flood damage reduction projects).
Cost Shares for Construction and Operation and Maintenance
The feasibility study also evaluates how construction costs will be split between the federal
government and the nonfederal sponsor. The cost-share responsibilities for construction and
O&M vary by project purpose, as shown in Table 2. Corps projects generally have primary
purposes of navigation, flood and hurricane storm damage reduction, and/or aquatic ecosystem
restoration. The agency also has the authority to undertake activities with other purposes as part
of multi-purpose projects. Table 2 lists these additional project purposes, which can be added to a
project that has at least one of the three primary purposes at its core.
How to allocate the construction and O&M costs of Corps projects among nonfederal sponsors
and the federal government has been debated for decades. WRDA 1986 significantly increased
local cost-share requirements; some subsequent WRDAs made further adjustments in cost
sharing. The waiving of cost-share requirements for individual projects is infrequent and typically
requires specific authorization by Congress.17
Engineering and Design
The study phase—preconstruction engineering and design—that follows the feasibility analysis
takes two years, on average, and is conducted while pursuing congressional authorization for the
project and construction funding (33 U.S.C. §2287). Preconstruction costs are distributed between
the federal and nonfederal sponsor in the same proportion as the cost-share arrangement for the
construction phase. Once the project receives congressional authorization, federal funds for
construction are sought in the annual Energy and Water Development Appropriations Act. The
federal cost share for construction varies by project purpose. Nonfederal parties are responsible
16 WRRDA 2014 authorized 34 new construction projects. Of these, 25 had been transmitted by the Assistant Secretary
of the Army, and 9 were awaiting the Assistant Secretary of the Army’s transmittal of a completed Chief’s Report
when Congress sent the legislation to the President. WRRDA 2014 did not authorize any project without a Chief’s
Report. At times Congress also has authorized construction of a small set of projects prior to the availability of
informational copies of feasibility studies; these construction authorizations generally are contingent on a favorable
Chief’s Report or a determination of feasibility by the Secretary of the Army.
17 Congress has established that the cost shares shall be subject to the nonfederal sponsors’ ability to pay (33 U.S.C.
§2213(m)(2)); however, it is rarely employed. The most recent publicly available guidance on how the Corps
implements the ability to pay provision is from 1989, which is available at http://140.194.76.129/publications/eng-regs/

Changes After Construction Authorization
A project is likely to undergo some changes after authorization. If project features or the
estimated cost change significantly, additional congressional authorization may be necessary.
Authorization for a significant modification is typically sought in a WRDA. For less significant
modifications, additional authorization often is not necessary. Section 902 of WRDA 1986 as
amended (33 U.S.C. §2280) allows for increases in total project costs of up to 20% without
additional authorization for modifications that do not materially change the project’s scope or
function.
Study and Project Deauthorization
Although WRDAs largely are authorization bills, Congress at times has used WRDAs to
deauthorize projects and establish deauthorization processes. Authorizations of Corps
construction projects generally are not time limited; however, there are processes for
deauthorizing them. These include the following:
• WRRDA 2014 creates a one-time process to deauthorize projects that have
federal costs to complete of $18 billion; this deauthorization process is restricted
to projects authorized prior to WRDA 2007.
• WRRDA 2014 requires that any project authorized in WRRDA 2014 is
automatically deauthorized if after seven years of enactment no funding had been
obligated for its construction.
• Under Title 33, Section 579a(b)(2) of the United States Code,, the Secretary of
the Army is directed to annually transmit to Congress a list of authorized projects
and project elements that did not receive obligations of funding during the last
full five fiscal years. The project deauthorization list is published in the Federal
Register. If funds are not obligated for the planning, design, or construction of
the project or element during the following fiscal year, the project or element is
deauthorized.18
For studies, there are two deauthorization processes:
• WRRDA 2014 requires that any feasibility study that is not completed seven
years after initiation is automatically deauthorized.
• Under Title 33, Section 2264 of the United States Code, every year the Secretary
of the Army is directed to transmit a list to Congress of incomplete authorized
studies that have not received appropriations for five full fiscal years. The study
list is not published in the Federal Register. Congress has 90 days after
submission of the study list to appropriate funds for a study; otherwise the study
is deauthorized.19
18 The Secretary last transmitted a new list of construction projects eligible for deauthorization in 2007; those
deauthorizations became final in 2009. Without a secretarial transmittal of a list, the deauthorization process is not
initiated. There have been no deauthorizations under this authority since 2009.
19 CRS has no data indicating that studies have been deauthorized through this process in recent years.

Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
Other Corps Activities and Authorities
Although the project delivery process described above is standard, there are exceptions. The
Corps has some general authorities to undertake small projects, technical assistance, and
emergency actions. Congress also has specifically authorized the Corps to undertake numerous
municipal water and wastewater projects. These exceptions are described below.
Small Projects Under Continuing Authorities Programs
The Corps’ authorities to undertake small projects are called Continuing Authorities Programs
(CAPs). Projects under these authorities can be conducted without obtaining a project-specific
study or construction authorization or project-specific appropriations; these activities can be
performed at the discretion of the Corps. For most CAP authorities, Congress has limited the size
and scope of the projects, as shown in Table 3.20 The CAPs are typically referred to by the section
number in the bill where the CAP was first authorized.
In recent years, Congress has reduced the Corps’ discretion in managing the CAPs by directing
funds to particular CAP projects. Congress also increasingly has authorized specific CAP
projects. Some of these project-specific authorizations under the CAPs are used to apply special
requirements to a project or to ensure that a project is considered eligible under a particular CAP.
WRRDA 2014 requires the Assistant Secretary of the Army to publish prioritization criteria for
the CAP projects and an annual CAP report.
20 There is also an authority under 33 U.S.C. §610 for the Corps to control noxious aquatic plant growths at a 70%
federal - 30% nonfederal cost share; the authority is capped at $15 million annually. This authority has not been
operated as a CAP. Most, but not all, of the work under this authority has been for research.

apply to these studies. Until then, reductions in nonfederal costs are not to be applied.
Natural Disaster and Emergency Response Activities
National Response Framework Activities Under FEMA
The Stafford Act (42 U.S.C. §5170b) authorizes the Federal Emergency Management Agency
(FEMA) to direct the Department of Defense to provide assistance for a major disaster or under
an emergency declaration by the President. Under the National Response Framework, the Corps
coordinates emergency support for public works and engineering. This includes technical
assistance, engineering, and construction management as well as emergency contracting, power,
and repair of public water and wastewater and solid waste facilities. The Corps also assists in
monitoring and stabilizing damaged structures and demolishing structures designated as
immediate hazards to public health and safety. It also provides technical assistance in clearing,
removing, and disposing of contaminated and uncontaminated debris from public property, and
establishing ground and water routes into affected areas; contaminated debris management is
coordinated with the U.S. Environmental Protection Agency. The Corps’ funding for these
activities is provided through FEMA appropriations, often through supplemental appropriations.
Congressional Research Service
13
Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
Flood-Fighting and Emergency Response
In addition to work performed as part of the National Response Framework, Congress has given
the Corps its own emergency response authority. This authority is commonly referred to as the
Corps’ P.L. 84-99 authority, based on the act in which it was originally authorized, the Flood
Control and Coastal Emergency Act. P.L. 84-99 (33 U.S.C. §701n) authorizes the Corps to
perform emergency response and disaster assistance.21 P.L. 84-99 authorizes disaster
preparedness, advance measures, emergency operations (disaster response and post-flood
response), rehabilitation of flood control works threatened by floods, protection or repair of
federally authorized shore protection works threatened by coastal storms, emergency dredging,
and flood-related rescue operations. These activities are limited to actions to save lives and
protect improved property (public facilities/services and residential or commercial
developments). The Corps also has some authorities to assist with select activities during drought.
Most of the Corps disaster response work performed (including the repair program described
below) generally is funded through supplemental appropriations provided directly to the Corps.
Until supplemental appropriations are provided, Congress has provided the Corps with authority
in Title 33, Section 701n of the United States Code to transfer money from ongoing Corps
projects to emergency operations.
Repair of Damaged Levees and Other Flood and Storm Projects
In P.L. 84-99, Congress also authorized the Corps to rehabilitate damaged flood control works
(e.g., levees) and federally constructed hurricane or shore protection projects (e.g., federal beach
nourishment projects) and to conduct related inspections. This authority is referred to as the
Rehabilitation and Inspection Program (RIP). To be eligible for rehabilitation assistance, the
project must be in active status at the time of damage by wind, wave, or water action other than
ordinary nature.22 Active RIP status is maintained by proper project maintenance as determined
during an annual or semiannual inspection and by the correction of deficiencies identified during
periodic inspections.23 Approximately 14,000 miles of levees participate in RIP—2,250 miles of
locally constructed and operated levees; 9,650 miles of Corps-constructed, locally operated
levees; and 2,100 miles of federally operated levees.24
For locally constructed projects, 80% of the cost to repair the damage is paid using federal funds
and 20% by the levee owner (as shown in Table 2). For federally constructed projects, the repair
cost is entirely a federal responsibility (except for cost of obtaining the sand or other material
used in the repair). For damage to be repaired, the Corps must determine that repair has a

Shoreline Erosion Protection program) and recovery (e.g., a Snagging and Clearing for Flood Control program).
22 33 U.S.C. §701n. For more on RIP, see U.S. Army Corps of Engineers, Engineer Regulation 500-1-1, Emergency
Employment of Army and Other Resources Civil Emergency Management Program.
23 An aspect of RIP implementation receiving attention is the Corps’ guidance on vegetation on levees. Some levee
owners are having difficulty conducting regular maintenance and emergency repairs while also complying with
environmental laws, such as the Endangered Species Act. In some areas, the vegetation on and near levees provides
species habitat and other environmental benefits. WRRDA 2014 provided congressional direction regarding updating
and content of guidance associated with vegetation on levees. This and other environmental issues associated with
levee maintenance are beyond the scope of this report.
24 Corps data provided to CRS on April 30, 2010. In January 2009, the Corps published a temporary extension of RIP
to locally operated levees with deficient conditions if the owner is making system-wide improvements. It is available at
http://www.iwr.usace.army.mil/nfrmp/docs/HQS-ECOPY3I50-Exchange-01132009-162045.pdf.

favorable benefit-cost ratio. Local sponsors assume any rehabilitation cost for damage to an
active project attributable to deficient maintenance.
Environmental Infrastructure/Municipal Water and
Wastewater Projects
Since 1992 Congress has authorized and provided the Corps with funds to assist with design and
construction of municipal drinking water and wastewater infrastructure projects (including
treatment facilities such as recycling and desalination plants, and distribution and collection
facilities such as stormwater collection and recycled water distribution) and surface water
protection and development projects. These projects are broadly labeled environmental
infrastructure. Although no Administration has included environmental infrastructure in a Corps
budget request since the first authorization in 1992, Congress regularly includes Corps
environmental infrastructure funds in appropriations bills. Environmental infrastructure projects
repeatedly have been called out by various Administrations as a low priority for the agency and
by the co-chairs of the National Commission on Fiscal Responsibility and Reform.25
Most Corps environmental infrastructure projects are authorized for a specific geographic
location (e.g., city or county) under Section 219 of WRDA 1992 (P.L. 102-580), as amended;
however, other similar authorities, sometimes covering regions or states, exist in multiple sections
of WRDAs and in select Energy and Water Development appropriations acts. Management of the
Corps and nonfederal financing varies according to the specifics of the authorization. Under
Section 219, the Corps performs the authorized work; for environmental infrastructure projects
authorized in other provisions, the Corps often can use appropriated funds to reimburse
nonfederal sponsors for work they perform.
Since 1992, Congress has authorized the Corps to contribute to more than 400 of these projects
and programs, with authorized appropriations totaling more than $5 billion. WRRDA 2014
expands authorizations and their authorization of appropriations for specific environmental
infrastructure activities in multiple states. The Corps received $140 million for environmental
infrastructure projects in FY2010 and $200 million in the American Recovery and Reinvestment
Act of 2009 (P.L. 111-5). The Administration did not fund any environmental infrastructure
activities in its FY2013 work plan. Congress recommended $44 million for these projects in
FY2014 and $50 million for FY2015 in explanatory statements accompanying appropriations
bills.
Because environmental infrastructure activities are not traditional Corps water resources projects,
they are not subject to the Corps planning process (e.g., a benefit-cost analysis is not performed),
or to the deauthorization process previously described. The projects, however, are subject to
federal laws, such as the National Environmental Policy Act. As indicated in Table 2, most Corps
environmental infrastructure financing is 75% federal and 25% nonfederal.

Appendix. Evolution of the Its Civil Works Mission
The Corps’ oldest civil responsibilities are creating navigable channels and flood control projects.
Navigation projects include river deepening, channel widening, lock expansion, dam operations,
and disposal of dredged material. Flood control projects are intended to reduce riverine and
coastal storm damage; these projects range from levees and floodwalls to dams and river
channelization. Many Corps projects are multipurpose—that is, they provide water supply,
recreation, and hydropower in addition to navigation or flood control. Its environmental activities
involve wetlands and aquatic ecosystem restoration and environmental mitigation activities for
Corps facilities. The agency’s regulatory responsibility for navigable waters extends to issuing
permits for private actions that might affect wetlands and other waters of the United States.
Navigation and Flood Control (1802-1950s)
In the 19th century, the Corps’ mission evolved into civil and military building for the nation. In
1824, Congress passed legislation charging military engineers with planning roads and canals to
move goods and people. In 1850, Congress directed the Corps to engage in its first planning
exercise—flood control for the lower Mississippi River. During the 1920s, Congress expanded
the Corps’ ability to incorporate hydropower into multipurpose projects and authorized the
agency to undertake comprehensive surveys to establish river-basin development plans. The
modern era of federal flood control emerged with the Flood Control Act of 1936 (49 Stat. 1570),
which declared flood control a “proper” federal activity in the national interest. The 1944 Flood
Control Act (33 U.S.C. §708) significantly augmented the Corps’ involvement in large
multipurpose projects and authorized agreements for the temporary use of surplus water. The
Flood Control Act of 1950 (33 U.S.C. §701n) began the Corps’ emergency operations through
authorization for flood preparedness and emergency operations.26 The Water Supply Act of 1958
(43 U.S.C. §390b) gave the Corps authority to include some storage for municipal and industrial
water supply in reservoir projects at 100% local cost.
Changing Priorities (1960-1986)
By the late 1960s, construction of major waterworks had declined. Changing national priorities
and local needs, increasing construction costs, and completed projects at most prime locations
decreased the attractiveness of water projects. Water supply for traditional off-stream uses, such
as domestic, commercial, industrial, and agricultural uses, was increasingly in direct competition
with in-stream uses, such as recreation, fisheries, and wildlife habitat. From 1970 to 1985,
Congress authorized no major water projects, scaled back several authorized projects, and passed
laws that altered project operations and water delivery programs to protect the environment. The
1970s marked a transformation in Corps project planning. The 1969 National Environmental
Policy Act and the Endangered Species Act of 1973 (16 U.S.C. §1531) required federal agencies
to consider environmental impacts, increase public participation in planning, and consult with
other federal agencies. Executive orders (E.O. 11988 and E.O. 11990) united the goals of
reducing flood losses and environmental damage by recognizing the value of wetlands and
required federal agencies to evaluate potential effects of actions on floodplains and to minimize
impacts on wetlands.
26 Emergency response activities are also conducted under the Disaster Relief Act of 1974 (42 U.S.C. §5121), also
known as the Stafford Disaster and Emergency Assistance Act.
Congressional Research Service

Army Corps of Engineers: Water Resource Authorizations, Appropriations, and Activities
Corps Regulatory Activities: Permits and Their Authorities
The Corps has several regulatory responsibilities and issues several different types of permits. Sections 10 and 13 of
the Rivers and Harbors Act of 1899 (22 U.S.C. §407) require that a permit be obtained from the Corps for alteration
or obstruction of and refuse discharge in U.S. navigable waters. The Corps also has regulatory responsibilities under
other laws, notably Section 404 of the Clean Water Act (33 U.S.C. §1344), which requires a permit for dredging or
fil ing activities into waters of the United States. Since the mid-1960s, court decisions and administrative actions have
altered the jurisdictional reach of the Corps’ regulatory program. For more information on the Corps’ Clean Water
Act authorities, see CRS Report 97-223, The Army Corps of Engineers’ Nationwide Permits Program: Issues and Regulatory
Developments, by Claudia Copeland and CRS Report RL33483, Wetlands: An Overview of Issues, by Claudia Copeland.
The Corps also regulates and authorizes disposal of materials into the ocean under the Marine Protection Research
and Sanctuaries Act; for more information, see CRS Report RS20028, Ocean Dumping Act: A Summary of the Law, by
Claudia Copeland.
Environmental Mission and Local Responsibility (1986-2000)
Congress fundamentally transformed the rules for Corps water project planning and funding
through WRDA 1986 (33 U.S.C. §2211); it established new cost-share formulas, resulting in
greater financial and decision-making roles for local stakeholders. WRDA 1986 reestablished the
tradition of biennial consideration of an omnibus Corps civil works authorization bill. WRDA
1986 also provided the Corps with authority to determine if changes can be made in existing
structures or operations to improve environmental quality. WRDA 1990 (33 U.S.C. §§1252,
2316) explicitly expanded the Corps’ mission to include environmental protection and increased
the Corps’ responsibility for contamination cleanup, dredged material disposal, and hazardous
waste management. WRDA 1992 (33 U.S.C. §2326) authorized the Corps to use the “spoils”
from dredging in implementing projects for protecting, restoring, and creating aquatic and
ecologically related habitats, including wetlands. WRDA 1996 (33 U.S.C. §2330) gave the Corps
the authority to undertake aquatic ecosystem restoration projects. While the Corps has been
involved with numerous environmental restoration projects in recent years, WRDA 2000
approved a restoration program for the Florida Everglades that represented the agency’s first
multiyear, multibillion-dollar effort of this type. These legislative changes gave the Corps an
aquatic ecosystem restoration and environmental protection mission.
Evolving Demands and Processes (2001-present)
The agency’s aging infrastructure and efforts to enhance the security of its infrastructure from
terrorism and natural threats have expanded Corps activities in infrastructure rehabilitation,
maintenance, and protection. WRDA 2007 continued the expansion of the Corps’ ecosystem
restoration activities by authorizing billions of dollars for ecosystem restoration activities,
including large-scale efforts in coastal Louisiana and in the Upper Mississippi River. The Corps
also retooled its long-standing flood control mission to use a flood risk management approach.
This was undertaken in response to congressional direction in WRDA 2007 and disasters like
Hurricanes Katrina, Rita, and Ike and the significant floods in the Midwest. This approach
emphasizes a greater appreciation for the shared responsibilities across levels of government for
managing flood. The regularity with which the Corps has received significant congressional
appropriations for natural disaster response (e.g., Hurricane Sandy) has increased attention to its
role in emergency response, infrastructure repair, and post-disaster recovery. WRRDA 2014
expanded opportunities for nonfederal participation in project delivery and financing and aimed
to improve the efficiency of Corps planning activities.
