Village of Westmont: I object/have concerns with the petition.
• “The Village of Westmont has reviewed the request for a variation for the property at 4001 Park Street, Westmont, IL 60559, to reduce the required corner side setback from 20 feet to approximately 12 feet 10 inches for a building addition. Per a boundary agreement with the Village of Downers Grove, this property is located within the Village of Westmont's future annexation area. If the property is annexed in the future, it would be incorporated into the Village of Westmont. The likely zoning district designation would be the R-3 Single-Unit Detached Residence District, which requires a minimum street-side setback of 15 feet. The Village of Westmont does not support the requested variation because the 12 foot and 10 inch proposed setback fails to meet the Village's minimum street-side setback requirement and would create non-conforming issues when annexed into the Village.”
