For fiscal year 2012, Congress appropriated almost 1.7 billion to the Corps for its Civil Works program to construct a wide range of projects, including flood control projects. Flood control projects require congressional authorization and appropriations. Nonfederal sponsors, such as a state or local government, also provide funds. When Congress approves a project for construction, it authorizes a total cost for the project based on estimates prepared by the Corps, and this authorized cost provides the basis for the project s maximum cost. GAO was asked to review issues related to flood control projects. This report examines 1 the extent to which cost increases occurred and the primary factors that contributed to the differences between estimated and actual costs, 2 the extent to which the Corps communicated with and provided updated information to nonfederal sponsors, and 3 Corps guidance on communication with such sponsors and ways, if any, to improve such communication. GAO surveyed Corps officials on all 87 flood control projects identified by the Corps as budgeted for construction in any fiscal year from 2004 to 2012, selected 8 for further review covering each Corps division, reviewed project documents and Corps communication guidance, and interviewed Corps officials and nonfederal sponsors. GAO recommends that the Corps take steps to ensure compliance with its guidance calling for communications plans. The Department of Defense concurred with the recommendation.
