Question

Your friend has just bought a house, and he is going to be putting in a new driveway. The town he is moving to is located 10 km from the coast and has a temperate climate. The house is at the top of a hill, and the slope of the area that will become the driveway is steep and is surrounded by trees on both sides. At the bottom of the hill is a main road. The neighbors directly across the street have a sloping downward driveway to their house, which is located at a moderate slope. Your friend has five choices for a driveway: 1) Leave it the way it is and drive on the grass; 2) tear up the grass and cover it with sand; 3) tear up the grass and cover it with small pebbles; 4) tear up the grass and cover it with slightly larger rocks (1–2"); or 5) tear up the grass and pave it with asphalt. Discuss the pros/cons to each type of driveway with regard to what you know about the local climate, topography, sediment transport, mass wasting, hydrology, and future climate predictions. Which would you recommend your friend use for his driveway, and what should he be aware of if he chooses that option?
