Start with the small list:
Get a PO Box
Longer term rental search
Include insurance on it so they pay directly for rental. Find a nice place that you like, don't settle.You should be able to get a "Like Property" so insurance should cover a nice place for you to live while you work through all this.You might be living here for 2 years, so choose wisely.
Find a place to buy some sturdy boots and gloves.Get some shovels.
Start working on the personal property list
As you buy things, tell the store owner your situation.Most stores will give you some level of discount as their way of helping you.
The Big List:
Register at the shelters, with Red Cross and any other agency there, California FEMA, etc.
Most of the aid coming in will use these lists as a point of contact and will help to ensure that you don't get left out of anything.
This will be especially important should FEMA be activated, which in my opinion is very likely with the amount of devastation experienced.
Call Homeowners/Rental insurance to trigger "Loss of Use"
This typically will allow you to be in a "Like" property for x number of years and sometimes has a dollar limit attached and sometimes not, this is dependent on your policy.
This coverage should also give you some immediate access to funds for essentials, clothes, toothbrushes, food, etc.
This will also get the ball rolling for the insurance claim on your home and rebuilding/personal property Dollars.
Get a PO Box and forward all mail to the Box.
Start Searching for a Long term rental.
Coordinate with your insurance company so that payments can be made directly from them using your “Loss of Use” money.
Plan on renting 1-2 years, but do not necessarily sign a lease for a full two years as circumstances can change.
Itemized List of belongings - (This is very hard but very necessary for your claim)
I would organize by room and list everything that was there with a replacement cost. (you will cry a lot doing this and that is ok)
Replacement Cost should be what it would cost to replace not on sale from pottery barn, it should not be the price you paid for it with that 50% off coupon.
Make sure you list everything, even if it is above and beyond your policy limit.This is very important because everything above and beyond the policy limit is considered a Loss and can be claimed as such on your taxes - See #9
Call all of your utilities and either freeze or cancel service.
Electric, Gas, TV, Land Line phone
Newspaper delivery, either cancel or update to PO Box.
Call the rest of your insurance points as needed.
Permits - An unfortunate necessity.
Debris Removal - as things wind down it will be necessary to remove the debris, this requires a permit usually. (This should be covered by your insurance, we had to force the issue but ask repeatedly.)
Erosion Control - If you are on any kind of hill or have sloped property you will need to put some sort of erosion control measures in place, again this will need some sort of permit.
Temporary Power Pole/Trailer on site Permit - Getting this earlier on can prove helpful in both the rebuilding process.
Consult a tax professional, but here are some tips that might apply:
You might be able to claim the monetary loss of the value of all your items minus what you receive from your insurance company
