AlertMarin is the primary notification system used by agencies across the County. We use AlertMarin to send you critical information and potentially life-saving instructions. We use AlertMarin to send alerts during emergencies like flooding, wildfires, or evacuations, when action is needed at a specific address or location. An AlertMarin notification will give you timely, clear, and accurate information. AlertMarin notifications can be a phone call, text message, or email.
