Colorado Land Surveyor Practice Exam

What is required if the roadway surface is paved with two inches of thickness or greater?

1. The monument box must be raised above the pavement

2. The monument should be laid flat with no cover

3. The box top must be set flush with the surface of the pavement

4. The monument must be completely removed

The correct answer is: The box top must be set flush with the surface of the pavement

The requirement for a roadway surface that is paved with a thickness of two inches or greater is that the box top must be set flush with the surface of the pavement. This ensures that the monument is accessible for future surveying and maintenance tasks while maintaining a smooth roadway surface. When the monument box is flush with the pavement, it helps to prevent any potential damage to the monument itself and makes it less of a hazard for vehicles and pedestrians. Raising the monument box above the pavement, laying the monument flat with no cover, or completely removing the monument are not practical solutions in this context. Raising the box could lead to damage and create a trip hazard, while laying it flat may cause it to become obscured over time due to debris or soil accumulation. Completely removing the monument would eliminate an important reference point for future surveys, which is counterproductive to the purpose of land surveying.
