Landscaping Drainage

The landscaper put underground drainage to far behind the house for every gutter downspout.

Also, on the side of the house that gets a massive amount of water due to the slope of the land, he is installing a 6'' catch basin to collect all rainwater away and past the house.  This entire pipe will be buried and exit into the woods...

Before the catch basin, we would get a creek on the side of the house with a heavy rain...
