Right, more info, It was an official from the county council planning department. He claimed that the soil might damage established trees lower down the slope, although he admitted that he knew nothing about trees, so he was not qualified to say. Run-off would not be a problem, as I own the paddocks below the terrace. The road is some 200 yards from the terrace, uphill to the north, my land slopes to the south.
He also mentioned the lorries bringing the topsoil in, but they do not approach from the direction of any dwellings, they deliberately come from the opposite way, which is open farmland. The road is frequently used by heavy tractors, but no-one complains about them.
He said I had to stop immediately, I asked if I could bring soil in to make a vegetable patch. At present that part of the land is almost pure sand. He said no. I asked how I was to grow my food without suitable soil, he told me to buy it from the supermarket.
At that point I asked him to leave.
