High Tides: Stay Prepared for Coastal Flooding
As we move through January and February, Southern Marin communities can expect some of the highest tides of the year, increasing the potential for coastal flooding—especially when high tides coincide with rainstorms, wind, or storm surge. These conditions are common during winter and can impact low-lying waterfront areas, roads, homes, and businesses.
High tides don’t always mean flooding, but preparation is key. Even minor flooding can cause property damage, disrupt travel, and create safety hazards if residents aren’t ready.
What You Can Do Now
Before High Tides and Storms
· Clear drains and gutters: Remove leaves and debris from storm drains, gutters, and downspouts so water can flow freely.
· Have sandbags ready: Protect doors, garages, and other low entry points in flood-prone areas.
· Secure outdoor items: Bring in or tie down patio furniture, trash bins, and loose items that could wash away.
· Check sump pumps and drains: Make sure they are functioning properly before storms arrive.
· Prepare an emergency kit: Include flashlights, batteries, medications, and important documents.
· Plan ahead: If you live or work near the waterfront, plan alternate travel routes during peak tide periods.
During High Tide Events
· Avoid driving through flooded roadways.
· Keep clear of seawalls and shorelines during high surf.
· Follow local advisories and official updates.
Stay Informed and Connected
