Preventing Mudslide Damage

Flood damage in the Los Angeles Basin is intensified in foothill areas where vegetation has been destroyed by major brush fires. In such cases, storm water comes off the hills carrying soil, rocks, trees or brush. The Los Angeles County Department of Public Works offers these tips for homeowners:

Never underestimate the power of flows of debris.

Try to direct debris flows away from structures by using materials such as sandbags, sand or lumber.

Avoid trying to confine the flow more than is absolutely required. Always use protection to deflect debris, but do not dam or stop it.

Debris will often enter a building through windows. Board them up during a flow.

Protect your most valuable property first--your home. Then consider what time and money are available to protect less valuable objects such as swimming pools or plantings. Be prepared to sacrifice the use of portions of your property to achieve good protection.

Be prepared to take action during storm periods. In many cases, a minor correction will prevent major failure. But do not take unnecessary risks.

For long-term protection, install more permanent measures to prevent damage.

Try to work with owners of adjacent property.

Should debris control problems appear to warrant measures in excess of what you can accomplish on your own, consult an expert such as a civil engineer.
