Officials with the nonprofit organization that oversees youth baseball in New Canaan on Wednesday unveiled a dramatic plan to improve the little league baseball fields at Mead Park with larger dimensions and new fences, light poles, bleacher areas and scoreboard. New Canaan Baseball also is seeking to reorient Gamble Field so that home plate is located where left field currently sits and the diamond fans out in the same general direction as Mellick, according to the organization’s president, Jim Higgins. “Our overall guiding principle in terms of what it is we wanted to accomplish was we wanted to stay generally within the footprint of what is there,” Higgins told members of the Park & Recreation Commission at their regular monthly meeting, held at Lapham Community Center. “We are sensitive to reorganizing anything or disrupting any other part of the park, so the plan that we have come up with is substantially within the existing boundaries of the two fields. A couple of the key goals were drainage, trying to get state-of-the-art drainage and the right materials underneath the grass, because we lose a lot of game days due to rain—and not just on the days it rains, but the drainage is not as good as it could be.
