There are thousands of existing gardens on borrowed land. Call some of the more established ones and ask if you can see theirs. Or call a city hall somewhere, where community gardens are encouraged. They may provide a sample contract. Lawyers and legal websites have many basic contract forms that they work from. This isn't a new thing and with a little searching, I expect that a suitable contract form will be found.
In some places, lots have little value. Where they are sold for under $1000, it might be better to buy. Cities like Detroit, Buffalo, Cleveland and others in the rust belt, give long term tax relief on projects like yours.
I once spent a few days investigating dozens of lots in Niagara Falls New York. Prices ranged between $25 and $200. I didn't pursue my building scheme, because the market was flooded with houses under $25,000.
