Here are some tips on how to deal with flooding in your home:

-Rent a large trash container.
-Take pictures of everything you throw out.
-Wet drywall must be removed a foot higher than the waterline. 
-If you move to a hotel ask for a Red Cross Rate.
-Expect to pay out of pocket until Insurance & FEMA payments arrive.

More Info & details from someone who dealt with flooding from a past storm:

Insurance and FEMA will ask you to list the contents of EVERY drawer in your house. Literally. How many tubes of toothpaste did you throw out? How many tubes of mascara. How many pairs of shoes? What brand of mattress did you have? When did you buy it? How many sets of sheets? Your mind is reeling and you can’t remember. Keep a camera in your pocket and take pictures of EVERYTHING – including the brand/style/etc of the item. Every drawer, every cabinet, every closet. You will not remember how many boxes of macaroni and cheese you have – but they will ask about what was in your pantry, fridge and freezer. How many designer items? They will want you to differentiate.

If you have any wet documents you want to keep, freeze them. You can thaw them later but they will start to mildew unless they are frozen.

If there are ANY dry cleaners open, take ALL of your clothes to them. Mildew will start within a day or two and then they cannot save the clothes. Insurance will pay for the cleaning so don’t worry. Just get someone to take the clothes to the nearest cleaners and drop them off.

Obviously the best hotel is one with a kitchenette. If you are staying there for a while you will want that option.

If you have receipts for anything in your house – find them. If you buy anything – anything – save the receipts. You will need this for insurance.

Go to store and buy plastic tubs. Use them to pack the things you can salvage. They stack easily and don’t dissolve if things are wet.

Order a pod. They will drop one in your driveway and use it to store the things you want to keep. They can take the pod away once it is full and keep it until you decide what to do with your stuff.
