Voters in Cohoctah Township are casting ballots today in a special election on a rezoning request. Resident Vern Brockway wants his property in the Oak Grove area rezoned from residential to commercial in order to put up a gas station and brick convenience store. That request was approved by the township and county, but a group of residents led a petition drive to place the issue on the ballot citing traffic and environmental issues. Brockway has denied either of those would be problems and has indicated that the group may be using the referendum to keep out competitors. Officials say there are about 2,300 registered voters in Cohoctah that could potentially cast their ballot on the issue with around a 50 percent voter turnout anticipated. Polls will be open until eight tonight.
