Colorado Land Surveyor Practice Exam

What minimum length must the monument for any corner possess?

1. 20 inches

2. 30 inches

3. 36 inches

4. 25 inches

The correct answer is: 30 inches

The requirement that a corner monument must be a minimum of 30 inches in length is based on land surveying standards to ensure stability and visibility. This length allows the monument to be securely embedded in the ground while providing enough height above the surface for clear identification. A monument that meets or exceeds this length is less likely to be disturbed or displaced by environmental factors, such as erosion or landscaping activities. Additionally, a monument of this height ensures it can be easily located by surveying professionals in future surveys, which is critical for maintaining accurate records of land boundaries. Other options do not meet the minimum standard established for corner monuments. Lengths shorter than 30 inches would increase the risk of monuments being disturbed or overlooked, leading to potential disputes regarding property lines, while the standard supports reliability and consistency in land surveying practices.
