Corps Of Engineers Water Resources Infrastructure

Over the past century, the U.S. Army Corps of Engineers has built a vast network of water management infrastructure that includes approximately 700 dams, 14,000 miles of levees, 12,000 miles of river navigation channels and control structures, harbors and ports, and other facilities. Historically, the construction of new infrastructure dominated the Corps' water resources budget and activities. Today, national water needs and priorities increasingly are shifting to operations, maintenance, and rehabilitation of existing infrastructure, much of which has exceeded its design life. However, since the mid-1980s federal funding for new project construction and major rehabilitation has declined steadily. As a result, much of the Corps' water resources infrastructure is deteriorating and wearing out faster than it is being replaced. Corps of Engineers Water Resources Infrastrucutre: Deterioration, Investment, or Divestment? explores the status of operations, maintenance, and rehabilitation of Corps water resources infrastructure, and identifies options for the Corps and the nation in setting maintenance and rehabilitation priorities.

The U.S. Army Corps of Engineers (Corps) is responsible for construction, operations, and maintenance of much of the nation's water resources infrastructure. This infrastructure includes flood control levees, multi-purpose dams, locks, navigation channels, port and harbor facilities, and beach protection infrastructure. The Corps of Engineers also regulates the dredging and filling of wetlands subject to federal jurisdictions. Along with its programs for flood damage reduction and support of commercial navigation, ecosystem restoration was added as a primary Corps mission area in 1996. The National Research Council (NRC) Committee on U.S. Army Corps of Engineers on Water Resources Science, Engineering, and Planning was convened by the NRC at the request of the Corps of Engineers to provide independent advice to the Corps on an array of strategic and planning issues. National Water Resources Challenges Facing the U.S. Army Corps of Engineers surveys the key water resources challenges facing the Corps, the limits of what might be expected today from the Corps, and future prospects for the agency. This report presents several findings, but no recommendations, to the Corps of Engineers based on initial investigations and discussions with Corps leadership. National Water Resources Challenges Facing the U.S. Army Corps of Engineers can serve as a foundational resource for the Corps of Engineers, U.S. Congress, federal agencies, and Corps project co-sponsors, among others.

The U.S. Army Corps of Engineers (Corps) is the worlds largest public engineering, design, and construction management agency, with water resources infrastructure in every state, authorized for various purposes including navigation, flood and coastal storm damage reduction, hydropower, and water supply. The Corps plans, designs, and operates water resources infrastructure projects, such as dams, levees, hurricane barriers, floodwalls, and floodgates, that may be affected by extreme weather events. This book discusses the Army Corps of Engineers and their water resource work in the areas of extreme weather events; levee safety; dam safety (cost sharing of repairs); and operations/water control manuals.

The U.S. Army Corps of Engineers has long been one of the federal government's key agencies in planning the uses of the nation's waterways and water resources. Though responsible for a range of water-related programs, the Corps's two traditional programs have been flood damage reduction and navigation enhancement. The water resource needs of the nation, however, have for decades been shifting away from engineered control of watersheds toward restoration of ecosystem services and natural hydrologic variability. In response to these shifting needs, legislation was enacted in 1990 which initiated the Corps's involvement in ecological restoration, which is now on par with the Corps's traditional flood damage reduction and navigation roles. This book provides an analysis of the Corps's efforts in ecological restoration, and provides broader recommendations on how the corps might streamline their planning process. It also assesses the impacts of federal legislation on the Corps planning and projects, and provides recommendations on how relevant federal policies might be altered in order to improve Corps planning. Another important shift affecting the Corps has been federal cost-sharing arrangements (enacted in 1986), mandating greater financial participation in Corps water projects by local co-sponsors. The book describes how this has affected the Corps-sponsor relationship, and comments upon how each group must adjust to new planning and political realities.

The U.S. Army Corps of Engineers, through its civil works program, can take pride in its contributions throughout our nation's history to the development of waterways infrastructure, navigation, flood damage reduction, water resources development and protection, and environmental restoration. Many projects that have been pioneering in their concept and bold in their execution were made possible by the creativity and dedication of outstanding scientists, engineers, and builders. The Corps has always had review processes for evaluation of its planning studies and projects, with the focus often being largely on the technical aspects. In recent years, however, increased consideration of such factors as environmental impacts, economic evaluations, political pressures, and new paradigms about flood control and management has engendered increased criticism and concern that some of the Corps' studies may have led to conclusions, recommendations, and project decisions that are not adequately supported by the assumptions and analyses that were used. The focus of the report is on review of Corps of Engineers studies, with careful attention given to the need for independent, external reviews by panels of well-qualified and impartial experts for large, complex, and sensitive projects.
