As stated on the Town's website: "The Town of Concord depends upon the immense talent pool possessed by our citizens and we are always seeking interested townspeople to serve on citizen boards and committees, and also to carry out short-term projects. If you are willing to serve your Town on a voluntary basis and desire to participate in shaping the Town's future, please indicate your interest by filling out a 'Green Card'. Green cards are short forms for listing your areas of interest and any skills relevant to committee or project participation."
