the ground beneath me sags
The excavation next door to us seems to be causing subsidence in our yard. As I was hauling my bike up the steps last night in the gloom of yet another rainy evening, I felt some of the stones shift beneath my feet. It was the end of a very long day, and I wasn't entirely sure that I'd felt that right so I tried the spot again and sure enough, several of the bricks are on ground that seems to be giving way.
Given that there's a deep excavation immediately adjacent, and given the sandy nature of the soil, and given the incessant rain this year, I'm able to deduce that there's trouble brewing.
