Description

The Floodplain Management Services (FPMS) Program provides a full range of technical services and planning guidance in support of effective floodplain management and flood risk reduction. The program develops or interprets site-specific data on obstructions to flood flows; flood formation and timing; flood depths or stages; floodwater velocities; and the extent, duration and frequency of flooding. 

For more complex floodplain issues, the program provides assistance in the form of Special Studies for all aspects of floodplain management and flood risk reduction planning. Some of the most common types of Special Studies include: floodplain delineation/flood hazard evaluation studies; dam break analysis and dam removal studies; flood warning/preparedness studies; regulatory floodway studies; comprehensive floodplain management studies; urbanization impact studies; sedimentation effects studies; and stormwater management studies.

Although most Program services are provided without charge, based on available funding, certain services are provided only on a reimbursable basis.

Background

The Rock Island District's Floodplain Management Services (FPMS) program has been very successful in assisting other agencies (Federal and State), counties, local communities and individuals with addressing their floodplain management and flood risk reduction needs.

Status
A growing demand exists for the District's floodplain management services and related technical assistance capabilities due to: land use/land cover changes; climate change; floodplain development pressures; enhanced public understanding of and interest in floodplain functions and floodplain management; an expanding commitment to reduce flood damages through better floodplain protection and flood risk management options; and FEMA's ongoing flood insurance rate map modernization program as well as its many other flood risk reduction and management initiatives, programs and projects.

Additional Information

Active FPMS projects:

  1. Iowa Reservoir Dam Safety Study - This project is being accomplished by the Corps of Engineers to prepare modeling and mapping products for each of the flood control dams. These models will be the basis for real time models designed to define major flows from the reservoirs and the potential impacts on critical infrastructures in the floodplains below each dam.
     
  2. Maquoketa River Hydraulic Modeling - This project is being accomplished by the Corps of Engineers to prepare modeling and mapping products for the watershed. These models will be the basis for floodplain management decisions by the communities, the counties and the state.
     
  3. Levee Freeboard Forecasting GIS Tool - this project is being accomplished by the Corps of Engineers to develop a GIS tool to identify levee freeborad at the segment or sub-segment level for a given river. 
     
  4. Spoon River Hydraulic Modeling – This project is being accomplished by the Corps of Engineers to prepare modeling and mapping products for Fulton County.  These models will translate local flood forecasts to project specific impacts.

Potential New Starts:

  • Clive Hydraulic Model Alternatives
  • Shell Rock River at Clarksville Hydraulic Modeling
  • Small Communities Flooding Operations Planning Data
