PRINCETON — The Bureau County Board has tightened zoning requirements on future wind farm developments, but maybe not well enough, according to some board members.

At Tuesday’s meeting, the Bureau County Board reviewed an 18-page text amendment to the county’s zoning ordinance regarding wind farms, dealing with a wide range of issues, including setback requirements, noise and shadow flickering, and decommissioning.

Zoning Officer Kris Donarski presented the recommended text amendment in the absence of Zoning Committee Chairman Marsha Lilley. The Zoning Committee has worked on the wind farm amendments since last spring, Donarski said. The Zoning Board of Appeals, which reviewed the proposed text amendment, made no recommendation on the first half of the document, dealing, in part, with setbacks, noise and television reception interference but did recommend approval of the second portion of the document.
