I did a google search for “participatory democracy local government” (without the quotes) and I had an interest in these links:
Very Local Democracy at devolve.org
Prospects for Participatory Democracy in the U.S. at libertytreefdr.org
A Participatory Democracy for American voters at democraciaparticipativa.net
Citizen Participation, Neighborhood Planning And Empowerment Of The Poor at nhi.org
That’s it for now.
