The measure, previously approved by the Senate, passed 97-0.
According to the Chattanooga Times Free-Press Rep. David Alexander, R-Winchester, said the change would bring 56 parcels of mountain property, currently part of Franklin, into Marion County.
The reason, Alexander said, is a development on mountainous terrain that includes property in both counties. The private developers had built a road to the property on the Marion County side and it is inaccessible from Franklin County.
Both Marion and Franklin counties’ commissions have approved the boundary change, said Alexander, who didn’t recall the name of the mountain involved nor the total acreage of property.
