The Los Angeles Basin is periodically subject to devastating floods resulting in substantial property damage. Such damage is intensified by debris flows resulting from the destruction of the watershed by major brush fires.

During floods, the prime mission of your Department of Public Works is the control of flood waters in the major rivers and channels throughout the County.

The Department of Public Works has posted this site to assist you in the installation of inexpensive devices, which will cost less to install and repair than flood damage to your property.

The following discussion stresses solutions to problems of particular significance to the growing number of residents in hillside areas. These temporary solutions can be accomplished by individual homeowners. Although the information is intended to develop solutions to reduce the threat of flood damage, there is no guarantee that they will prevent damage or injury.

When the storm season arrives (October to April), flooding and debris flows occur, making it more difficult to perform emergency work. Therefore, I recommend you initiate your preparation for the rainy season immediately.
