The Flood Plain Management Services (FPMS) program is authorized by Section 206 of the Flood Control Act of 1960 (PL 86‒645), as amended. The U.S. Army Corps of Engineers developed the FPMS program specifically to address the needs of people who live and work in floodplains. This is a program to educate these individuals on flood hazards and the actions they can take to reduce property damage and prevent the loss of life. The program’s objective is to foster public understanding of the options for dealing with flood hazards and to promote prudent use and management of the nation’s floodplains.

Typical Types of Studies

The FPMS program provides the full range of technical services and planning guidance that is needed to support effective floodplain management. The most common types of studies are floodplain delineation, flood hazard evaluation, dam break analysis, hurricane evacuation, flood warning and preparedness, regulatory floodway analysis, comprehensive floodplain management, flood risk reduction, urbanization impacts, storm water management, flood proofing and inventory of flood-prone structures. The program also provides assistance for conducting workshops and seminars on nonstructural floodplain management measures such as flood proofing.


The Lake Wausau hydrodynamic study was initiated in fiscal year 2016. The goal of the study is to determine flow properties of the networked flowage channels to enable efficient water management practices and reduce flood risk. It was completed in January 2018 with the potential for additional studies based on recommendations in the final report. The local sponsors have indicated an interest in additional tasks based on the report findings.

New studies initiated in fiscal year 2019 include a comprehensive floodplain management plan for the city of La Crosse, countywide flood risk management plans for Trempealeau and Juneau counties, and the continuation of a multi-year statewide flood inundation mapping program in Wisconsin. The first river reach in progress for flood inundation mapping is the Baraboo River near Baraboo. The Trempealeau River at Arcadia has been initiated in fiscal year 2019.


Upon request, program services are provided without charge to state, regional and local governments; federally recognized Native American tribes; and other non-federal public agencies. Entities may provide voluntary contributions toward requested services to expand the scope or accelerate the provision of these services. Program services are also offered to non-water resource federal agencies and the private sector on a 100 percent cost recovery basis, paid before services are provided.
