Sonoma County Water Agency, California

In October 2017, the Sonoma County region experienced damaging firestorms. The resulting fire burn scars and ground conditions throughout the Tubbs and Nuns area left the region highly vulnerable to life-threatening flash flooding and debris flows during heavy rainstorms. Heading into the rainy season, a flood warning network was needed as quickly as possible. Led by Sonoma County Water Agency with assistance from OneRain, a complete ALERT2™ flood warning network was designed and installed from the ground-up to assist the County and National Weather Service in detecting flooding conditions. A new fully functional ALERT2 flood warning network was operational by the end of February 2018.
