Floods
High Water Mark
What You Need to Know
In LA County, climate change brings wetter, more intense storm events.
More rainfall means more flooding. But flooding can also be caused by faster snowmelt and rising sea levels, which can also impact water movement through our community. California faces several different types of flooding, each leaving our cities, ports and beaches with the same challenge: Where does all the water go and how will it affect people who live and work here?
Just like wildfires and other natural disasters, flood water can leave your home or business in physical danger and limit your access to resources in a local emergency.
Know Your Risk
Who IS Impacted Most?
More severe rainfall events affect everyone. However, inland flooding and extreme rain is especially difficult for:
Persons who are unhoused
Storms and flooding can ruin their shelter and belongings. Those who shelter by the river may not receive warnings of flood events where rising water levels may sweep away encampments and the people who live in them.
People with asthma
These people can be impacted by mold, which results from flooding and heavy rainfall.
People who live in mobile homes
Mobile homes have higher risk for flooding, damage and movement off of their foundation.
Those who count on libraries for internet access
Without internet access, many people can’t get the latest emergency alerts, news and social connections they need.
Households with no access to cars
These people often use public transportation (like the bus), which may not be running due to flooded streets.
