Water Resilience

Route 1, Bridge over Russian River

Abundant clean water is crucial to a resilient, sustainable, and thriving life for all Sonoma County residents and visitors. The Climate Action and Resiliency Division (CARD) collaborates on and helps to facilitate and implement projects aimed at improving Sonoma County’s water resilience.

Water Resilience can be understood as the ability of water systems to withstand or recover from change or stress, such as floods, droughts, or changes in water quality, without losing the system’s ability to support key functions and beneficial uses.
