I am planning to build a 10ftX12ft backyard shed in SF Bay. We have little rain
year round except spring and fall. The shed will be use to store boxes of books,
unused items on built in shelving and should be considered very heavy.

I need suggestion, advice or webpage's links for the required foundation. I am
not in a position of laying a concrete slab as it would be too troublesome to
mix or cart in pour concrete mixed from the front yard to the backyard. Thanks a
million.
