Flooding in Marin County and other parts of the Bay Area poses risks to low-lying neighborhoods, roadways, and infrastructure. The high tides could lead to water intrusion in homes and businesses, as well as disruptions to transportation. Residents in flood-prone areas should remain vigilant, as the situation may worsen depending on tidal patterns and additional weather developments. The use of Phoenix Lake for flood mitigation underscores the seriousness of the situation.
