Maintaining the grade around the house is important because poor drainage will double or triple the force and stress against the foundation walls and can cause lateral wall movement, heaving, and water damage.
Proper drainage is generally considered to be a 1” per foot drop away from the house for the first 6’ to 10’, and should be maintained throughout the life of the structure. Maintaining a properly functioning gutter and down spout system is also important.
