Generated explanation

The illustration shows a house on a contoured site with shallow drainage swales located away from the building. Arrows indicate surface runoff flowing down the higher ground behind the house into the swales. Large arrows show the collected water being diverted around both sides of the house and toward lower ground. This depicts site grading that directs surface water away from the home rather than allowing it to collect against the foundation.
