Zone 7 officials said it's important to know whether your property is at risk for flooding by looking up your address on the state's MyHazards website at http://myhazards.caloes.ca.gov.
From there, you can prepare your property by removing any dead trees or brush, making sure your drainage is directed toward the street's storm-drain system, and keeping all storm-drains, roof gutters, pipes, downspouts, driveway culverts and drainage ditches free of debris.
Landscaping is the best protection against slides, according to Zone 7. If your home is on a bare-soil hillside, you can protect it by punching straw into the soil with a shovel, or securing sheets of woven burlap with stakes.
They also advise residents that it's vital to correct any cracking or slippage as soon as possible and that directing drainage downslope onto bare soil can cause slope instability.
In case of serious flooding or slides, residents should stay prepared for possible evacuation by keeping your car fueled and disaster supplies handy.
Zone 7 suggests residents consider flood insurance where applicable, because most homeowners' insurance policies do not cover flood damage.
