I'm not sure how local you mean. In my neighborhood there's a neighbours commitee that works on making everything better, there's a local library and a few public squares. They collect monthly fees from members and vote on the council every three years. They didn't have a system to keep track of this and sometimes had issues really knowing all their members. I made them a real simple web app and it helped them a lot, I was already a member and they asked in the members Facebook group if there was a programmer.
