I attended Canada Bloom last month and came across this brilliant idea of directing water away from your house. The brown down spout at the top of the photo is where it the landscaping begins. It shows how the designer built a slow drop where eventually the water came to a ledge creating a small water fall. Ultimately, the water collected into another basin filled with pea gravel.
One of the biggest challenges with homes is getting the water directed away from the house! This is the best idea I have seen so far.
