OAKLAND, Calif. – The Federal Emergency Management Agency (FEMA) has delivered revised preliminary flood maps for the Unincorporated Areas of Plumas County, California. The maps identify revised flood hazards along more than 15 streams and channels throughout Plumas County. The new maps will help building officials, contractors, and homeowners make effective mitigation decisions, thereby contributing to safer and more disaster-resilient communities.
Before the new Flood Insurance Rate Maps (FIRMs) become effective, there is a 90-day appeal period from August 7, 2026 to November 4, 2026. During that time, residents or businesses with supporting technical and scientific information, such as detailed hydraulic or hydrologic data, can appeal the flood risk information on the revised preliminary maps, which can be viewed at hazards.fema.gov/femaportal/prelimdownload/.
Flood hazards are dynamic and change frequently for many reasons, including weather patterns, erosion, and community development. Officials from FEMA and Plumas County worked together to provide updated information that accurately reflects the flood risk. These changes may also affect future building standards or insurance requirements.
The local mapping project is part of a national effort led by FEMA to increase local knowledge of flood risks and support actions to address and reduce the effects of flooding on new and improved structures. FEMA encourages residents to review the revised preliminary flood maps to learn about local flood risks, potential future flood insurance requirements, and identify any concerns or questions about the information provided.
Risk of flooding affects almost every corner of the nation. In total, 98% of counties have experienced a flood event, which makes floods the most common and widespread of all weather-related natural disasters.
