Final answer:
Lot lines are normally found behind the sidewalk as they mark the boundaries of a lot, and the sidewalk acts as a public pathway for pedestrians.
Step-by-step explanation:
Lot lines are normally found behind the sidewalk. They mark the boundaries of a lot, which is a specific area of land. The sidewalk is a public pathway for pedestrians, and it is typically positioned between the lot line and the street. By placing the lot lines behind the sidewalk, there is a clear separation between private property and public space.
