I blame that on the realtors, Rich. They buy land in areas known to be near industry, and sell houses without informing the buyers of the issues. It happened in my neighborhood where folks on the far end were just an Interstate highway distance away from a rock quarry. Soon they were "shocked" that blasting was ocurring.
It's no different than chasing out the wild animals and the First Americans as we expand our population. At some point, all parties need to agree on how scarce land will be used.
In any case, it doesn't make sense to tell a former user they can't do what they were previously permitted to do when the suburbanites move in. Grandfathering is the common solution. Where I grew up, we had a fellow with a chicken farm around the corner. He was there before the post-WWII families moved in and declared that people couldn't keep farm animals. I was glad they allowed him to keep his chickens. I still remember summer days with the rooster crowing early in the morning as I tried to get my last hours of sleep. While others considered that a nuisance, it was music to my childhood ears.
It was certainly a lot more pleasant that jets breaking the sound barrier over our house.
