I have to agree with your take on this. We were recently sent an 'offer' by the local water district to buy 15' of frontage along our property for a new water line that will be a major service upgrade for about 8 homes.
My issue came when I discovered that the current water line and easement is on the other side of the road, but they would have to cut down quite a few tree while it was a lot easier to dig in front of my farm. So far, I get it. Then I could out that they offered us 3 cents per square foot of frontage but the home next to us was offered 4x as much at 4 cents per square foot. And someone else offer 4 cents, and they didn't even know about the 3 new houses on our road before they even started planning.
I'm all for improving infrastructure, but it needs to be in a fair, and well planned, way. Neither of which is common with this sort of thing.
