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 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 Souris hydrology and hydraulic study was requested by the North Dakota State Water Commission in response to the record flood of 2011. Fiscal year 2019 marks the eighth year of the North Dakota study, with the purpose of eliminating numerous knowledge gaps brought to light by the 2011 flood. The FPMS program was used to fund field surveys, hydrology models of the Souris and Des Lacs watersheds and numerous hydraulic model developments from the Canadian reservoirs in Saskatchewan to downstream border at Manitoba. These funds were leveraged with other studies by the North Dakota State Water Commission, Federal Emergency Management Agency and the Silver Jackets Program. Potential work includes further refinements to the hydrologic and hydraulic models, especially downstream of Minot, North Dakota to the Manitoba border. This work would include extending the unsteady flow model into Manitoba using existing cross section data to stabilize the downstream boundary conditions. A study to develop hydrologic and hydraulic models for Little Deep Creek in Ward County began in fiscal year 2018 to address chronic road overflow damage and culvert washout issues. That study is on-going, to be completed by the end of 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.
