Hello Beth, 

Thanks for reaching out to the UNH Extension Yard and Garden Infoline. It's exciting that you're on the journey to build a community garden! There is certainly a lot that goes into it so reaching out for help is a wise choice. 

The first place I would point you is to a guide to building community gardens that UNH Extension developed a few years ago called "From the Ground Up". It has a lot of great information. You can find it here-

Here is another resource from the University of Minnesota Extension about how to start a community garden-

After looking through those, I'm happy set up a time to chat about your project and I can try to answer any questions that you have about the process. I can also try to put you in touch with someone who has built a community garden before, if that would be helpful as well. 

I hope this helps and please ask if you have further questions!
