Question

Answer 1

The ground surface of a lot must be graded to drop a minimum of 6 inches within the first 10 feet away from foundation walls to prevent water from pooling and causing damage.

Step-by-step explanation:

The question is regarding the proper grading around foundation walls to ensure drainage of surface water. In construction and building codes, the standard often used is that the ground surface of a lot should be graded to drop a minimum of 6 inches within the first 10 feet away from the foundation walls.

This grading helps direct water away from the building and prevents water from pooling around the base, which could potentially lead to water damage or basement flooding. Proper grading is essential for maintaining the integrity of a structure's foundation and preventing water-related issues.
