Hello...
Hey, it's me. I haven't posted for a while, but I thought of something interesting that came from my bookmarks. All of you were talking about how much food to store in the supply cache, and I believe you mentioned using ISO containers, so I pulled up this archived website:

This website detailed a simple plan that could save around 800 people from a comet impact a la the movie Deep Impact, with materials and supplies you can easily find on the present-day, real-life open market. It could be prepared in less than three months (I think), and would be able to not only save them, but sustain them long enough to rebuild. Please note that the website in this archive is not complete, but most of the vital material is there.
According to the website, to feed 800 people for three years you would need one ton of grain for each person, such as from corn and soybeans (Which can be replaced with rice). This can fit in 18 40' ISO containers, holding 800 tons of grain altogether. Of course to supplement this you would add canned vegetables and meats (Which were home canned in the plan), as well as 12 gallons a head of cooking oil (9,600 gallons for 800 people). Also added would be roots and edible tubers, such as potatoes, carrots, etc, as well as powdered milk, salt, and canned fruits. While I haven't done the math for exactly how much of these supplemental foods would be needed per person for three years, I do know that all you would need to do is add some more containers, which were included by the creators of this plan (See the map of the shelter site - it's at

One more thing - when they made this plan, they proposed using a 20' ISO container to store 8 tons of wheat seeds and 8 tons of soybeans (Which would be non-hybrids, and would yield 240 tons of wheat and 270 tons of soybeans). I would think that when they said that smaller quantities of other seeds would be added, such as for fruits and vegetables, they could be stored in at least one more 20' container. While I think that they should have included more (In my opinion), they planned for two pairs of chickens and two pairs of rabbits to provide a little more nutrition as well as pelts and feathers when it is time to begin growing food.
So pretty easily, you could extrapolate this to meet your 3,000-person refugee camp. That's just my two cents.
