True or False: The soil is graded a few inches above the finished grade to leave room for topsoil.

The statement about grading the soil a few inches above the finished grade to leave room for topsoil is incorrect. Typically, the soil is graded to the finished elevation, with the necessary allowance made for various materials that will be applied afterward, such as topsoil. This topsoil is usually added on top of the graded subsoil to facilitate plant growth, but the grading itself is done to achieve the prescribed elevation of the project, not above it.

In a construction context, ensuring that the subsoil is correctly graded to the finished grade is crucial because it affects drainage, stability, and the overall aesthetics of the landscape. If the soil were graded too high, it could lead to problems such as insufficient drainage, erosion, or improper settling once topsoil is added. The proper grading practices dictate that the final grade should account for the thickness of the topsoil layer being applied.
