Legal Definitions - topographical survey

A topographical survey is a type of survey that determines the elevation of a property above sea level. It involves measuring the land and creating a map that shows the results of those measurements. This type of survey is important for construction projects, as it helps engineers and architects plan for the best use of the land.

• A construction company hires a surveyor to conduct a topographical survey of a piece of land they plan to build on. The surveyor measures the elevation of the land and creates a map that shows the contours of the terrain. This information helps the construction company plan for the best placement of buildings and infrastructure.
• A city government conducts a topographical survey of a park to determine the best location for a new playground. The surveyor measures the elevation of the land and creates a map that shows the areas that are level enough for the playground equipment.

These examples illustrate how a topographical survey can be used to plan for construction projects and other land use decisions. By understanding the elevation of the land, engineers and architects can design structures that are safe and functional.
