Surveys are used to identify boundaries and features of land to determine ownership. It is the scientific process of measuring the dimensions of a particular area of the earth’s surface, including its horizontal distances, directions, angles, and altitude. In this lesson, you’ll learn what a survey is and about the different types of surveys used today.
1. Boundary Survey
A boundary survey is used to locate the corners and boundary lines of a particular land. This type of survey involves both record and field research, including any measurements and computations needed to set the boundary lines in accordance with applicable state laws. A boundary survey may also involve locating easement lines and impacts.
2. Construction Survey
This type of survey requires staking out structures located on the property, including walls, buildings, roads, and utilities. Staking provides construction personnel with directions for implementing the improvements shown on the development plans. A construction survey may also involve both horizontal and vertical grading in addition to an As-Built survey.
3. Location Survey
Similar to a boundary survey, a location survey provides additional information on the location of interior improvements. This type of survey is most commonly used to fulfill the requirements of a zoning permit or loan application.
4. Site Planning Survey
Often a requirement for development permit applications, a site planning survey combines the elements of boundary and topographic surveys for site planning. This survey is used to plan design improvements and developments before construction begins.
5. Subdivision Survey
A subdivision survey is used to divide a parcel of land into smaller tracts, lots, or estates. This type of survey is also used to design streets and drainages, and it must be recorded by the local and state government agency. This survey is also known as a partition survey.
6. Topographic Survey
The purpose of this survey is to locate both natural and man-made topographic features on a parcel of land. Examples of such features include barriers, utilities, buildings, heights, streams, trees, improvements, and outlines. A topographic survey may be required by a state or local government agency or might be used by architects and engineers for planning site improvements and development.
