"The Federal Emergency Management Agency (FEMA) has prepared this guide specifically for homeowners who want to know how to protect their homes from flooding. As a homeowner, you need clear information about the options available to you and straightforward guidance that will help you make decisions. This guide gives you both, in a form designed for readers who have little or no experience with flood protection methods or building construction techniques. [...].You should take steps to protect your home if it has been damaged by flooding or is in an area where flooding is likely to occur. But first, you need to know what methods are available, how they work, how much they may cost, and whether they will meet your specific needs. This guide covers all of those issues. It also explains flood hazards and how they can damage your home. Don't forget that flooding is only one of several natural hazards that may threaten your home. This guide includes maps that will help you determine whether your home is in an area where earthquakes or high winds occur, and it also explains when your retrofitting project should in¬clude protection against these hazards."
