In as much as CDOT is one of the primary players in the restoration process, it's easy to focus on them but you also have the Federal Highway Administration and Army Corps Of Engineers just as importantly,county governments, local governments, water / municipal districts, taxing districts... etc, the list goes on. Along with private citizens concerns,though way down on the list, all have substantial stakes in this process. The idea of forming coalitions - work groups - study groups- stakeholder groups is an effective way of getting stakeholders / interested parties to the table to discuss the the restoration / rebuilding process, the ramifications of certain projects and the possibility of workarounds when opportunity presents itself. Getting educated to each stakeholders regulatory processes, long term / short term project goals and overall strategy for implementation is key to understanding where you can have the most effective input. Finding a way to establish some level of consensus building amongst group participants will go a long way toward maybe seeing the fruition of your ideas. It will cost you some time but may reap substantial rewards. I participated in the Hermosa Creek Watershed Protection Group a few years back for two years and out of the meetings came the basis for draft legislation for the Hermosa Creek Watershed Protection Plan. It's being held up with a slim chance of being passed at this point in Congressional Committee. But it was something I was passionate about, so it was worth the time, hopefully the politicians will agree. Unless you make the effort, the Bureaucracy will probably drown out your / our concerns. Start by finding a successful, knowledgeable experienced, well known, mostly objective moderator to help drive the group process.
