FEMA updates flood maps in Sacramento County and some cities

OAKLAND, CA. – The Federal Emergency Management Agency (FEMA) provided preliminary flood maps for Sacramento County and the cities of Citrus Heights, Folsom and Sacramento. The maps identify revised flood hazards along Arcade Creek, Cripple Creek, Hinkle Creek, the Humbug Valley Basin and tributaries to Alder Creek. These new maps will help building managers, contractors and owners make effective mitigation decisions, contributing to safer and more disaster-resilient communities.

Prior to the new Flood Insurance Rate Maps (FIRMs) taking effect, there is a 90-day appeal period from October 6, 2022 through January 4, 2023. During this period, residents or businesses with supporting technical and scientific information, such as detailed hydraulic or hydrological data, can call on the flood hazard information on the preliminary flood maps, which can be viewed at fema.gov/preliminaryfloodhazarddata.

Flood risks are dynamic and change frequently for many reasons, including weather, erosion, and community development. Officials from FEMA, Sacramento County and the cities of Citrus Heights, Folsom and Sacramento worked together to provide up-to-date information that accurately reflects flood risk. These changes may also affect future building standards or insurance requirements.

The local mapping project is part of a nationwide effort led by FEMA to increase local knowledge of flood risk 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 more about local flood risk, potential future flood insurance requirements, and to identify any concerns or questions regarding the information provided.

The risk of flooding affects almost every corner of the country. A total of 98% of counties have experienced flooding, making it the most common and widespread of all weather-related natural disasters.
