The network is best when you start by setting an example and then spread is. "Look, as part of my daily exercise I pick up a bit of trash every day. I'm in better health and look how much better my neighborhood is" This speaks more than someone needs to do something so I'm putting together a group to form a committee. Lead by example.
Yes, although I was thinking more along the lines of we should be neighbourly to each other hand have a good relationship where we say hi and watch out for each other. Giving people bureaucracy won't work. A number of the neighbourhoods where I live have block parties once a year so that people know there neighbours. And once you know your neighbours you can start talking about mutual problems and then things you might be able to do to fix it.
