Actually, one of the first times I participated in local politics, was to successfully block a large development (100+ units, some of which included "affordable housing" lol). The developer was a favorite of the state - they get all the big contracts all over the state, and some former government officials are on their board (no doubt accepting bribes for their influence). It was a coalition of residents that spanned partisan politics. Just showing up to meetings on these issues, and if you have any public speaking skills, highlight the ties of the corrupt local political class to the developer/construction companies - locals don't like being hoodwinked by that.
