Here's my advice: find out who your city council representative is. Make that person your friend. Attend city council meetings. Propose to start a "sustainable living" task force that's a public/private partnership. (I'd be happy to provide some basic guidance and point you in a direction for references.)
Here in Indianapolis, I've been working as a Commissioner on the Indy Green Print Commission. Our task is to offer guidance to the administration for implementing sustainable practices in local government. The Commission is comprised of Architects, Engineers, Builders, Utility Company execs, major industry execs (usually those involved in plant management), Community Development experts, etc. We're also heavily supported by city staff, primarily individuals from zoning, metro development, the parks department, the utility side, etc.
Keep up the pressure. It's a worthwhile charge.
