Topographic Survey

 A topographic survey, also known as an existing conditions survey or a ground survey, shows the features of the land. It may show contour lines that represent specific elevations relating to a predetermined project datum, indicating the three dimensional features of the property onto a two dimensional surface. A topographic survey typically includes both natural and man-made features. It is common to show hills, streams, lakes, and vegetation along with major buildings, fences, roads, transmission lines, and utilities. A topographic survey has a variety of uses including planning and zoning, site layout, engineering and architectural design, and construction.
