Council might change rules after Bowdoin College solar development approval While Bowdoin's solar array has been approved, Councilor Steve Walker hopes to set into place more specific outlines for environmental impacts and mitigation requirements for future developers. Share Councilor Steve Walker, who is also a project manager for the Maine Coast Heritage Trust, introduced zoning amendments at Monday’s meeting. In December, Walker raised concerns about the plant and animal habitat that the solar development would be built on, stirring controversy among town officials, the college and environmentalists. The proposed revisions outline a more specific process for determining environmental impacts and the required mitigation techniques that would follow.
