The Santa Clara River overflows in the Great Flood of March 2, 1938, which hit greater Los Angeles. Afterwrard the L.A. River was turned into a concrete flood-control channel … but the Santa Clara wasn’t. It might look dry most of the year, but when it rains, it’s prone to flash flooding. Take heed.

Due to the approaching rainy season, it is important to plan and prepare for the increased potential of flooding, mudslides, and debris run-off. Flowing water is an instant danger zone! The Los Angeles County Fire Department urges residents living in areas prone to debris flows and mudslides to be prepared for danger as winter approaches. Stay safe by doing this:

* Stay away from flood control channels, catch basins, canyons and natural waterways which are susceptible to flooding during periods of heavy rain.

* Do not attempt to cross flooded areas and never enter moving water.

* If flooding traps you in your car, stay inside. If the water rises higher, wait on top of your car for assistance. Do not step into moving water around your car.

* If you become isolated, seek the highest ground available and wait for help.

* If you see someone who has been swept into moving water, do not enter the water and attempt a rescue. Immediately call 911 for trained emergency rescue personnel and, if possible, throw them some type of floatation device.

* Know how to shut off all utilities. Remember, water and electricity do not mix.

* Obtain sandbags ahead of time! Sandbags (and instructions about how to use them) are available at most L.A. County fire stations. Call your local fire station to find out where sand and sandbags may be picked up.

The more prepared you are the better of chances for survival during a major water-related emergency. For more information on flood safety and disaster preparedness, please visit: http://fire.lacounty.gov/SafetyPreparedness/SafetyPreparedness.asp.
