Open Houses to Review Revised Floodplain Map Updates

Story County has a long, established history of floodplain management programs, through the review of applications and issuance of permits to record keeping and building a strong relationship between floodplain management and hazard mitigation for properties in unincorporated Story County. Story County is part of the NFIP Community Rating System (CRS). As a CRS community, a minimum 5-percent discount is applied to all flood insurance policies issued or renewed in unincorporated Story County. Story County entered the CRS Program at a Class 7 rating, entitling unincorporated residents within the Special Flood Hazard Area a 15% discount on their insurance premiums.

Story County’s flood risk information is being revised by the Federal Emergency Management Agency (FEMA) and updated flood hazard maps are available. You are invited to attend one or more of three scheduled brown bag Lunch and Learn sessions to discuss the proposed changes to the floodplain maps. These meetings provide opportunities to discuss the changes to floodplain maps in the Unincorporated Areas of Story County, Iowa (outside city limits.) The public is invited to visit anytime between 11:30 am - 1:30 pm on any of the following dates: February 6th, March 7th, and April 3rd. There will be no formal presentation, and participants are welcome to come and go throughout the two-hour event. All three sessions will take place in the Public Meeting Room (2nd floor) at the Administration Building - 900 6th Street in Nevada.

Flooding is the number one natural disaster in the United States. It is vital that property owners understand their risk and take advantage of tools or programs available to them, including flood insurance. These preliminary maps are an update of the existing maps, which date back to 2008, and will become the basis for Story County’s floodplain management measures. Insurance companies use these maps to determine flood insurance rates for buildings and contents.

As a result of these map changes, some buildings throughout Story County may, for the first time, be included in a high-risk flood zone, known as the Special Flood Hazard Area. This may result in those affected property owners being required to purchase flood insurance. FEMA developed an online tool called the “Flood Map Changes Viewer” that shows the preliminary and pending flood hazard data and allows the viewer to compare effective and proposed maps. The Flood Map Changes Viewer is available at
