How is a solar farm going to destroy road? During the construction? Around here, any project that damages roads or is projected to damage roads during construction has to pay to have the roads put back in like condition once the construction phase is finished. That should all be written into the deal.
And just like gravel pits, landfills, etc., that continuously damage the roads, they have to continuously pay to have them repaired. That's basic stuff.
The three families you've mentioned own the land. They're the only ones making profit off of it if it's corn, soybeans, timber, cattle, or solar panels anyway.
They're also the ones that'll be on the hook for any environmental damages downstream if anything leaves their property, be it manure runoff, AG chemical runoff, soil erosion, etc.
They could just as easily put in hogs right up to the property line or sell it for housing developments.
Those are the hazards of living in rural areas outside of zoned communities where there might be little to no code or code enforcement.
I know this, because I live outside of a city, in the county, where up until last year, there was no code enforcement. I could (and did) have a dilapidated truck sitting in the back of my yard for years. The neighbors didn't mow their lawn for years. Furniture piled up on front porches, dead cars in front yards, piles of junk and yard debris abound. All that drives down others' property values as well.
We have acreage about 9 miles away. It's zoned AG with residential exception. So, I pay AG taxes on it until we improve it with a house. At any give time, someone could open a gravel pit, a livestock farm, a confined feeding operation, a junkyard, etc, right next door.
Again, those are the hazards of living in an area with little to no zoning/code.
