Champaign County passed an ordinance in 1973 intending to turn the Wilber Heights neighborhood into a strictly industrial region. The regulation prohibits the rebuilding of or substantial repair to any home. The zoning ordinance, deeming all homes non-conforming, prohibits any resident from adding on or renovating more than 10 percent of the replacement value annually. The move lowered property values, residents said. The Champaign County Zoning Board of Appeals made a final recommendation on zoning changes to help those living in the Wilber Heights area on Feb.
