[Time Period] 40 years [Predictions] 
Small wood structures, such as houses, crumble away as they are attacked by mold and termite infestations. Although they can stand for years, stone and masonry deteriorates quickly when exposed to salts, such as from bird droppings or exposure to seawater. With no one left to repair them, minor leaks in earthen dams, such as the Trinity Dam in California, will get worse and eventually cause them to break.
