This is an easy trap to fall into. That one minority opinion which disagrees with your proposal, may well be representing a silent majority. When you need a two-thirds vote, everyone counts. It is imperative to reach out to minority groups and see what conditions may satisfy them. Factor in conditions that make a project a win - a win for all parties.

Unfortunately, residents often do not focus until late in the process and raise numerous questions at a late hour in the process. Through board elections, new residents moving into a community, and committee member's change, new ideas are generated. A public works manager and staff need to be committed to do whatever it takes to hold the project together prior to the vote. This may be holding special meetings, talking one on one with new board members, modifying conditions and adjusting the message to address everyone's concerns. The final principle is to never give up on a project that you believe is vital to the well being of a community.
