II. EMERGENCY HOME PROTECTION
GENERAL RULES
The previous section described various problems you may encounter during the rainy season. Below are some general rules to be followed in most cases involving flood waters, debris, and erosion.
NEVER underestimate the power of debris flows.
TRY to direct debris flows away from improvements.
AVOID trying to control or confine the flows more than is absolutely required.
CLEAR a path for the debris.
USE your house or building as a deflector, if necessary.
ALWAYS place protection to deflect debris, not to dam or stop it.
DEBRIS will often enter a building through windows - board them up.
REMEMBER to protect your most valuable property first - your home.
THEN consider what time and money are available to protect other less valuable objects such as swimming pools or landscaping.
TRY to install more permanent measures (Figs. 18 and 19) to protect your home. In general, the problem of debris flows will exist for several years after a burn. Sandbags usually last for only a year.
ALWAYS work with adjacent affected property owners.
BE prepared to sacrifice the use of portions of your property to achieve the greatest amount of protection.
AVOID altering drainage patterns that could worsen conditions for your neighbor.
