Planning for Flood Events

Planning for Flood Events
Flood prediction and inundation mapping has provided extremely valuable tools for local emergency management officials. Riley County Emergency Management, Riley County Police Department and Manhattan Fire Department are able to better plan for flood events using the inundation map library.

They are able to determine, foot by foot of flooding, which areas of town will be affected, what properties would most likely need to be evacuated and which streets need to be closed.

The Wildcat Creek Watershed Area Work Group began meeting in 2011 to focus on how to address flood hazards. The group's work was summarized in the Wildcat Creek Floodplain Management Plan, which helped the City of Manhattan secure a spot on FEMA's Community Rating System to reduce the costs of flood insurance for property owners along Wildcat Creek. The plan promotes a better understanding of flood hazards, decisions made on flood risk management, public participation and provides a formal action plan for what will be done in the future, according to the Corps of Engineers.

The Wildcat Creek map, the flood warning system and floodplain management plan are the result of months of planning, research and development. You can access the inundation mapping tool online.
Riley County and the City of Manhattan assembled flood impact data and served as the local technical and public points contact for the project. A detailed floodplain model and topographic information were provided by the Kansas Department of Agriculture-Division of Water Resources. The detailed model and terrain data were originally funded under a grant from the Federal Emergency Management Agency. Technical expertise in developing the flood maps, as well as project management, was provided by the Corps of Engineers. Technical expertise in location, installation and maintenance of the stream gauges was provided by the U.S. Geological Survey. Riley County, the City of Manhattan and U.S. Army Garrison, Fort Riley, Kansas, contributed funding for the ongoing maintenance of the stream gauges. Assistance in developing the flood maps and flood forecasting service was provided by the National Weather Service.
