A sound public infrastructure plays a vital role in encouraging a more productive and competitive national economy. In addition, public facilities are vital to meeting immediate as well as long-term public demands for safety, health, and improved quality of life. For example, transportation systems and water supplies directly support the nation's economy by facilitating the movement and manufacture of goods. Public schools, housing, parks and other facilities enhance the quality of life of Americans. When infrastructure problems occur, they can be very visible, and their effects can be widespread. Given the profound economic and social importance of the public infrastructure, it is crucial that federal, state, and local governments make prudent decisions on how to invest limited available resources. To address concerns about the government's investment in infrastructure, this General Accounting Office report describes (1) trends in the government's investment in infrastructure, (2) how federal agencies can improve their decision-making for the acquisition and management of infrastructure, and (3) the challenges to an effective investment in infrastructure at the federal level. Infrastructure is broadly defined to include facilities, structures, and land for public use and for other purposes, such as national defense. Briefly, the United States has historically made an extraordinary investment in its infrastructure. The federal government has spent an average of $149 billion annually since the late 1980s on the nation's infrastructure. The amount of federal spending on infrastructure shows a continuous downward trend since 1987, due, in part, to a reduction in defense spending. Federal spending for nondefense infrastructures shows a slightly upward trend. State and local government infrastructure spending shows an upward trend since the 1980s. To maximize the benefits of investments in infrastructure, federal agencies can improve their decision-making for the acquisition and management of infrastructure by following the best practices of leading government and private-sector organizations. Challenges faced by federal agencies in determining infrastructure investments include: 1. a general lack of accurate, consistent information on the existing infrastructure and its future needs; and 2. the federal budget structure does not prompt explicit debate about infrastructure spending that is intended to have long-term benefits. |
