CORPS OF ENGINEERS—CIVIL WORKSThe President’s Proposal:
The Agency's Major Challenges:
The civil works program of the Army Corps of Engineers (Corps) in the Department of Defense has three main missions: 1) reduce or prevent the expected damage caused by floods and storms; 2) facilitate commercial navigation; and 3) restore aquatic ecosystems. The Corps carries out this work in partnership with state and local governments and other non-federal entities. It also regulates development in navigable waters and wetlands, and is responsible for cleaning up about two dozen contaminated nuclear sites. For 2004, the budget proposes $4.0 billion in discretionary budget authority for the civil works program. OverviewThe civil works program funds activities in every one of the 50 states. The Corps is responsible for the operation and maintenance of 926 harbors; navigation locks and dams at 230 locations; 383 major lakes and reservoirs; and 75 hydropower facilities. It also is building more than 160 authorized water resource projects across the nation, and faces an enormous backlog of ongoing construction work—$23 billion in federal costs to complete the construction projects supported in the President’s 2004 Budget. Unfortunately, despite a large increase in funding in recent years, the backlog of ongoing work—that is, projects started, but not completed—has been growing, not diminishing.
Construction funds are spread ever more thinly as new projects add to the Corps workload. As a result, citizens expecting flood protection have to wait longer; farmers and manufacturers who want to ship their products overseas more quickly or less expensively may have to wait yet another year; and the schedules for restoring streams and wetlands will, again, have to be stretched out. The budget proposes a comprehensive strategy to reduce these adverse impacts on the many Americans who rely on the completion of worthy projects already underway, while increasing the net return from the nation’s investment in the civil works program. The approach proposed in the budget reduces the construction backlog over time (see accompanying chart). Under the traditional path of adding projects with little or no restraint, the backlog continues to grow inexorably. While the level of funding can affect the rate at which the size of the backlog changes, the measures taken (or not taken) to limit the number of projects that become eligible for construction ultimately will determine whether we are making progress or are falling further behind. Setting Construction PrioritiesThe construction program’s goal is to produce as much value as possible from available funds. The budget achieves this key objective by proceeding with only five new high-priority studies and one construction start, and by limiting the number of projects not actively under construction that are funded for engineering and design.
The budget includes a high level of funding for eight projects that provide a very high net economic or environmental return to society relative to their cost. These investments will aid waterborne transportation at key locations, reduce the risk of flood damage in two urban areas, help restore the Everglades, and improve the prospects for recovery of endangered species in the Missouri River basin and the Pacific Northwest. These projects are the highest priorities now under construction. The budget also provides the resources needed to complete 13 ongoing projects in 2004—removing them from the construction backlog. Seven will reduce flood damage, five will support commercial navigation, and one is designed to protect a commercial shipping channel from nuisance species.
To provide a basis for comparing all projects whose justification rests primarily on economic benefits, the Corps plans to make available information on each project annually. The Corps will rank these projects by the ratio of their remaining benefits to their remaining costs to complete, and will show for each of them the ratio of net benefits to total costs. Like the rest of the government, in calculating the effects of capital investments the Corps plans to present these data using a seven percent discount rate. This discount rate approximates the average real rate of return on private capital in the United States.
Flood Control in Tucson
Between 1920 and 1954, the city of Tucson placed more than one mile
of a local stream, the Tucson Arroyo, in covered culverts. Flood damages
have occurred primarily because the city has grown considerably since 1954.
Urban development prevents rainfall from seeping into the ground, and the
limited capacity of these culverts caused water to back up and flood some
areas. To reduce flood damage, the Corps proposed building two series
of detention basins to hold back water upstream of the bottleneck. The first
group of detention basins, located in the Randolph Park area, would cost
about $14 million and provide an estimated net return of 36 cents per dollar
at a cost of $12.6 million (a 1.36 to 1 benefit-cost ratio). The second
group of detention basins, located in the Park Avenue area, would cost about
$17 million but would provide only a marginal net return on investment—about
nine cents per dollar (a 1.09 to 1 benefit-cost ratio). Under the
new policy, which aims to maximize the net benefits of the program and takes
into account limitations on investment funds, the second group of detention
basins would not be recommended for construction.
Benefit and cost information is only as useful as the analyses that produce it. The Corps will focus on developing options that are highly cost-effective. It plans to design and recommend projects that provide higher net benefits for each dollar invested, by excluding potential features and increments that do not significantly increase total net benefits relative to the costs. The objective is to ensure that any proposed new construction start is highly justified. Through the elimination of marginal features and incremental upgrades, additional funds can be made available to accelerate the completion of projects already under construction. Problems With Some Projects
The Corps has played an important role in developing the nation’s water resources, but it often faces difficult decisions. Some projects have strong local support, yet may not ultimately be in the national interest. In a number of cases, people have pointed to potential weaknesses in the Corps planning process. For example:
Estimating Navigation Benefits Properly
In estimating the benefits of some inland waterways navigation projects,
the Corps historically has used an economic model called the tow-cost model.
For the inland waterways of the Upper Midwest, the tow-cost model predicts
that a growth in barge traffic could back up barges for increasingly long
periods as the barges wait to use the locks—because more barges will
enter the system and just sit there until it becomes cheaper to ship bulk
commodities by land all the way to New Orleans. However, a recent
report by the National Academy of Sciences (NAS) concluded that the Corps
needs a new model to form the foundation for evaluating benefits in its
feasibility study of this river system. The old model does not predict
human behavior very well. Congestion increases shipping costs.
According to the NAS report, as costs begin to increase, and barge traffic
sits and waits, the people who buy and sell bulk commodities will begin
to seek out new markets. For example, they may decide to ship the
same commodities by land to a different destination or to process the goods
in the Upper Midwest first. The Corps recognizes that its tow-cost
model does not capture this common sense response, and is developing a new
economic model so that it will be able to estimate properly the economic
benefits of a range of possible improvements on these waterways.
Principles for Improving Program PerformanceThe Administration proposes five broad principles to guide future Corps authorization and funding legislation.
Common MeasuresWetlands. There are many different types of wetlands. They can serve multiple purposes such as fish and wildlife habitat, replenishment of groundwater, flood protection, and enhanced water quality. Wetlands still occur naturally across the nation—along the banks of our major rivers and our local streams; in the salt marshes behind the barrier islands of the Atlantic coast; the non-tidal forested backwater areas of the lower Mississippi River alluvial valley; the low-lying prairie potholes of the Dakotas; and the highest meadows of the eastern Sierra. There is no easy way to compare their quality and no way to quantify their value. Using a rough common performance measure—the acres of wetlands improved or protected per $1 million in total costs—OMB has been working with federal agencies that play crucial roles in wetlands conservation, improvement, and management to compare the cost-effectiveness of their efforts. These agencies are the Corps, the Environmental Protection Agency, the Department of the Interior’s Fish and Wildlife and National Park Services, the Department of Agriculture’s Natural Resources Conservation Service (NRCS), and the Department of Commerce’s National Oceanic and Atmospheric Administration. The costs of wetlands projects can be affected significantly by land values, the availability of water, vegetation type, soil and substrate conditions, and other factors. To facilitate a comparison across agencies and projects, the agencies have gathered data on their activities in four specific watersheds over a five-year period.
On a per-acre basis, the Fish and Wildlife Service programs appear to be far more cost-effective than those of the other agencies, and the Corps construction program appears to be the least cost-effective. However, the data are preliminary and do not address possible differences in wetlands quality or other factors that may affect the cost of projects. OMB and the agencies will work together in 2003 to determine whether these data provide a reasonable basis for comparison of their overall wetlands efforts. Flood Damage Reduction. OMB also compared the cost- effectiveness of the Corps, NRCS, and Federal Emergency Management Agency (FEMA) flood damage reduction programs. Corps projects generally involve structures such as dams or levees that redirect the impact of flood waters. NRCS projects usually feature a combination of dams, other structural modifications to a streambed, and payments to owners whose property will remain susceptible to flooding (to purchase easements). FEMA uses a variety of strategies to reduce flood damage, including non-structural measures such as buying buildings and relocating residents away from floodplains. OMB asked these agencies to evaluate projects that they completed over a five-year period where flood damage reduction was the primary purpose. Because the projects within each agency’s program vary greatly in cost-effectiveness, the following table uses the median project as a basis for comparison:
As the table shows, each agency’s median project will result in estimated net flood damage reduction benefits. While the three projects depicted in the table are all cost-effective, the Corps project is the most cost-effective. However, several Corps projects resulted in a low economic return on investment. Over the five-year period, the two most cost-effective projects were funded by FEMA. The three projects with the least cost-effective flood damage reduction features (which resulted in a negative net economic return) were funded by NRCS. OMB also asked the agencies for information on the federal share of the costs for their flood damage reduction projects. On average, the Corps and FEMA paid about 74 percent, while NRCS paid 82 percent. NRCS paid a much higher share of the costs of several projects. On its median project, NRCS paid 91 percent. Performance Evaluation of Select Programs
Update on the President’s Management AgendaThe Corps recently reinstituted a formal in-house training program and a separate, graduate-level education program to strengthen the capabilities of its project planning staff. The Corps also is reviewing its current organization and management in an effort to improve the quality and objectivity of project planning work. The Corps will make changes to strengthen oversight of project studies, without causing unwarranted delays. As a first step, it will establish one or more centers of expertise that will be responsible for studies of projects that are likely to be costly, complex, or controversial.
