WET FLOOD PROOFING:
This is generally the least expensive floodproofing technique, but it’s also the least effective in the long term. The strategies here result in a home still suffering through a flood, but strive to decrease the damage to the home and your contents.
Permanent or contingent measures applied to a structure and/or its contents that prevent or provide resistance to damage from flooding by allowing flood waters to enter the structure. FEMA
Techniques that fall under this definition include installing flood vents to minimize structural damage, relocating the electrical panel and the utilities above the base flood elevation (BFE), anchoring the foundation and any fuel tanks to minimize movement or destruction and protecting your personal belongings.

This technique requires active participation on the part of the homeowner. Many times, if not most, there are days of warning prior to a flood hitting your home. With the exception of a flashflood and possibly a catastrophic tsunami, you have time to move your personal belongings out of harms way.
Get busy! Move your stuff!

PROTECT YOUR CONTENTS
A simple idea to protect personal belongings is to utilize a section of your home that does not flood, e.g, a second floor, and start by moving everything upstairs. Family pictures, important documents, anything you don’t want to be destroyed – move it. We’ve used this method several times. It’s exhausting, but effective.
Another idea to protect your home’s contents is to rent out storage space at a storage facility. Most times your flood insurance will cover these costs after a flood warning has been issued. We utilized this option during a flood threat and basically emptied the entire family room (couches, tables, toys, books, etc.). This option provides great piece of mind, but a bit more planning.
During the last flood event, before we decided to lift our house, I decided if I had to move all of my furniture anyway, I may as well move it out of the house altogether. That way it would be easier to start the clean-up and rebuilding process.
Wet Floodproofing will still leave you with a big clean-up effort, requires active participation just prior to the flood event, and offers no reductions in flood insurance premiums. It’s better than nothing – much better.
When the water’s rising, do something – even if it’s just moving all of the items in your house upstairs.
