You have not seen my hillside. LOL Five terraces and a couple of hills with no back of lot access. Your assumption was correct not to long ago. Today moving stuff down hill is sure easier than hauling it all to the thirty foot higher back of the lot. My driveway is the first hill. It is not paved because a car would not stay on the driveway in snow or ice if it were paved. I never actually worked on an actual height gain measurement. I assure anyone it is at least 30 ft in 220 feet of length. My boys were born with one leg shorter than the other. We are not quite in the mountains but just about. Local faulting pushed up our hill. A hundred years ago our lot would have been in the foothills of the mountain. Millions of years ago it was all the bottom of the Atlantic Ocean.
