What local data is Santa Rosa providing to FEMA for the Flood Risk Mapping Project?
  1. FEMA relies heavily on communities to provide local flood risk information, including technical data. The City and Sonoma Water, Santa Rosa’s flood control district, are providing local hydrologic and hydraulic data to FEMA from the Santa Rosa Creek Flood Study completed in 2023.  FEMA will use the local data and their own to develop Preliminary FIRMs and Flood Insurance Study (FIS).
