FEMA Updates Flood Maps in Sonoma County

Santa Rosa, Calif

– The Federal Emergency Management Agency (FEMA) has delivered preliminary flood maps for Sonoma County and the City of Santa Rosa, California

The maps identify revised flood hazards along 12 streams throughout Sonoma 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 January 20, 2026 to April 20, 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 preliminary maps, which can be viewed at hazards

 Flood hazards are dynamic and change frequently for many reasons, including weather patterns, erosion, and community development

Officials from FEMA, Sonoma County, and the City of Santa Rosa 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 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
