Awesome set up my friend. I like the large scale swale for such a small yard. You'll maximize production on such a wide swale and soak up a lot of water. Good job.
I agree that it makes no sense the way neighborhoods are set up to move water away as fast as possible. Its the same with farming actually as well. This water could slowed down and soaked into swales on contour, planted with fruits, nuts and vegetables running the entire neighborhood and not only feed people but ialso make a nice place to live.
