Winnebago Floodplain Information Assistance

Winnebago County participates in the Community Rating System sponsored by the National Flood Insurance Program (NFIP) wherein individuals with property located in a floodplain, and who are required to hold flood insurance, may receive a reduction in flood insurance premiums if the participating community undertakes certain activities. One of the activities required is making map determinations, and publicizing the information to lenders, insurance agents and realtors. As a requirement of county participation in this program, please be advised of the following information: The Winnebago County Zoning Office will provide assistance to persons inquiring about floodplain property within the unincorporated area of Winnebago County.

The following information will be provided (available in our office for all floodplain construction since 1990):

  • Community Number FIRM suffix
  • Base Flood Elevation Copies of Elevation Certificate
  • Panel Number Date of the FIRM's index (cover panel)
  • Elevation datum system Floodway information and regulations, Historical Flooding and Wetland information

Our office is located in the: David Albrecht Administration Building, 112 Otter Ave, 3rd floor Oshkosh WI 54901

Please be advised that as of March 17, 2003, new FEMA floodplain maps are in effect for the entire area of Winnebago County, unincorporated and incorporated areas alike. There are a total of 42 maps covering the entire county. Maps are available from FEMA.
