Event Details
Jefferson County’s flood insurance rate map updates are nearing completion. The new maps will provide Jefferson County with more accurate flood risk information that can help local officials and residents make informed decisions about reducing flood risks and purchasing flood insurance.
The mapping project is a joint effort with Jefferson County, City of Boulder, Town of Whitehall, and Montana Department of Natural Resources & Conservation. It is part of a nationwide effort led by the Federal Emergency Management Agency (FEMA) to increase local knowledge of flood risks and support actions to address and reduce those risks.
Before new flood insurance rate maps in Jefferson County can become effective, there is a 90-day appeal period during which local residents and business owners can provide additional data for consideration before the maps are final. This appeal period starts September 10, 2025.
Community officials encourage residents and business owners to review the proposed flood insurance rate maps to learn about local flood risks, potential future flood insurance requirements, and any concerns or questions about the information provided.
You may submit an appeal package during the 90-day appeal period. The sole basis of the appeal must include the possession of knowledge or information indicating that the flood hazard determinations proposed by FEMA are scientifically and/or technically incorrect.
