Your property's floodplain designation is determined by a Flood Insurance Rate Map (FIRM) issued by FEMA. A property's floodplain designation indicates the likelihood of a flood event. For example, a property with a floodplain designation of AE has a 1% annual risk of flood. Floodplain designations are used by lenders to determine if flood insurance is required. They are also used by the Planning Department to enforce the Floodplain/Floodway Overlay District regulations.
Floodplain designations can be viewed online through the Sarpy County Internet Map Service. Please note that the information provided through this resource may not reflect recently issued Letters of Map Amendment or Revision. If you believe that a Letter of Map Amendment or Revision has been issued please utilize the Planning Department's map information service.
The Planning Department provides a map information service to assist citizens with determining their floodplain designation. It is important to know your flood risk. Our staff is dedicated to assisting you with your floodplain inquiries. If you wish to utilize our service, please fill out the Mayor's Hotline Floodplain Information form or contact the Planning Department at 402-597-2077. Additional floodplain resources are available at the Sump Memorial Library.
