First let me say that I am completely unfamiliar with New York so this may or may not be an option for you but you may want to consider renting a small climate controlled storage space. I have two of them in different locations that I keep supplies at.

The downside is that there is an ongoing cost with monthly rent but the upside is that my supplies are stored in a dry, dark place that is maintained at 70 degrees year round and I have 24 hour access. Another plus is that it is very easy to rotate out goods that expire, etc.

Just an idea...
