1517 is surrounded by what appear to be medium-sized houses on all sides. There’s no way of telling from the air whether they’re in use as homes or offices, but they don’t have parking lots, and Google Earth doesn’t have any businesses listed. The closest clearly commercial structure is a motel three doors up, about .14 miles.
Google Earth doesn’t have plat maps, of course, so I can’t be sure where Ward’s property ends, but it looks to be several acres. More than big enough for, say, a supermarket. The surrounding lots appear to be much smaller. The board might have been concerned about the scale of a commercial operation that could open on Ward’s property.
But whatever the board’s rationale, and whether their decision was right or wrong, Bo Ward’s business was in trouble because he borrowed more money than he could afford, and the zoning decision did not take from him anything he had when he decided to incur that debt. And it should go without saying that if the board was wrong, an appeal is a better option than suicide.
The address of Bo's Barber Shop appears to be 2531 Fort Campbell Blvd, not 1517 Madison St.
Madison Street is not US Highway 41, but US Highway 41A
US Highway doesn't even go through Clarksville, TN
