A group of Ridgefield residents are seeking changes to town ordinances when it comes to alternative energy installations. Concerns over the look of a solar array led to a proposal that the visual impact of the installations be drawn up in a new ordinance. The Ridgefield Zoners previously approved a ground-mount solar array in the residential Canterbury Lane area and neighbors say it looks to industrial. The proposal will be discussed at the Board of Selectmen's meeting next month. Any new ordinance would have to be approved at a town meeting.
