When buying or selling a property, you will need some type of land survey for your project. There are different types of land surveys, each with its own purposes and advantages. Two of these are boundary and topographical surveys. In this blog, we will go over their similarities and differences to help you decide which one is suitable for your construction project.
What Is a Boundary Survey?
As the name implies, boundary surveys are used to map out the exact boundary lines of a property. Knowing where the property ends and begins is necessary for any land transaction. By determining the perimeter of the property, you avoid encroachments and boundary disputes. Property lines should be measured by a licensed surveyor to ensure all the work is legal.
When Do You Need a Boundary Survey?
In general, boundary surveys are necessary for real estate transactions. A professional land surveyor will check land titles and existing survey plans. After reviewing all relevant documents, they will conduct fieldwork before creating the survey report.
Here are the common reasons you might need to get a boundary survey:
- Purchasing or selling a land
- Addressing boundary disputes with a neighbor
- Installing a fence around the perimeter
- Starting a home addition or improvement project
Features Shown on a Boundary Survey
- Lot’s size or dimensions of the property
- Locations of any easements
- Exact fence lines
- Any easements and encroachments
- Limitations and zoning regulations
- Any improvements made by previous owners
How Much Does a Boundary Survey Cost?
Whether you’re buying a property or tackling a home addition, you will likely pay around $100 to $600 on average. The lot type and size, location, and complexity of the terrain are the factors in calculating the survey costs. Reach out to your local land surveyor to get a free estimate on your project.
Topographical Surveys
While the standard boundary survey establishes the legal boundaries, it does not provide topographical data on the specific land. This is where topographic surveys come in. A topographic or topographical survey shows the coordinates and elevation of the land. It identifies the natural and human-made features of the land, such as the terrains, rivers, trees, fences, buildings, and more.
A topographic survey focuses more on elevation and contours than property lines. Topographic data is useful if you’re planning to develop the land. To determine the contour lines and existing features, an electronic distance measurement (EDM) or a GPS survey unit can be used. These survey instruments and computer programs can generate digital and interactive topographic maps.
When Do You Need a Topographical Survey?
Hiring a land surveyor for your topographical survey is recommended. Before conducting the survey, they review the existing maps and geographical area. They will gather survey data on-site and process it. Lastly, the survey team will prepare the report or topographic map.
Topographic surveys may be required for the following:
- Conducting a building or road construction project
- Undergoing environmental restoration and property improvements
- Fulfilling regulatory requirements for construction codes
- Submitting land registry data
- Developing a parcel of land
- Identifying grading, drainage, and utility issues
Features Shown on a Topographic Survey
- Changes in elevation
- Land contour lines
- Geological features
- Rivers and streams
- Slopes and terrains
- Buildings
- Fences and walls
- Streets and walkways
- Utility poles
- Manholes
How Much Does a Topographic Survey Cost?
A topographic survey typically costs from $500 to $1,200. Survey rates will vary depending on the plot area size, location, significant topographical elements, the equipment used, and accuracy required for the project. Another factor that might influence the costs is the time your surveyor will spend on the project. The best way to know the topographic survey expenses is to contact a professional land surveyor for an estimate.
