What is a Topographic Survey?
Though the typical land survey does include details of the boundary of land, a topographic survey is more concerned about the man made and natural features of the land. These features may include fences, trees, streams, buildings, hills, ravines, and any other components that make up the land.
At Long Beach Land Surveyors, we provide information regarding size, height, location, and contours or gradual changes in the land’s elevation. Unlike a boundary survey, a topographic survey is less focused on the horizontal measurement. We make most of our measurements using an electronic EDM instrument and a GPS unit.
We don't mark the results of the survey with landmarks or stakes; instead, we use contour lines to draw a map of the land. These days, surveyors can create digital versions of the maps with the help of computer-aided design and drafting software. This technology provides interactive elevation views of the property and gives architects and engineers the ability to demonstrate how you can expect topography to change over time.
When Do You Need a Topographic Survey?
There are many possible uses for a topographic land survey. In fact, just about every new construction starts with this type of survey because it helps define the land's starting point before starting the new improvement. Architects and engineers rely on these surveys to help them design improvements, like a new building, as well as how existing features can influence the decision on where a new building can and cannot be constructed.
Likewise, constructors use topographic surveys to develop their plans for drainage ditches as they use the natural landscape to make the process easier. In some cases, a government agency may also require that a topographic survey be conducted, such as is required under state regulation, or if the government plans an environmental restoration project.
Topographic surveys can be helpful when a parcel of land is being fully redeveloped from its previous use. For example, where a landfill or quarry used to function, or where a building was otherwise demolished, a topographic survey is necessary for the new construction. In these situations, you can obtain an accurate idea of how the land has changed over time, which allows the architect and engineer to design the new buildings with the most accuracy possible.
