Rancho El Dorado Parkway, a loop road in the Rancho El Dorado housing area of Maricopa, crosses a wash without benefit of a bridge or berm. Normally it looks like the scene in the upperr image. The dry view was captured a few days after the wet one, which explains the presence of sand in the road.

When it rains, much of the neighborhood drainage ends up in the wash, as seen in the lower picture. The water on the road is at most two inches (5 cm) deep. When flooded, the road is closed.

Both photos look eastward along the northern crossing of the wash. I took both photos in January 2016 while standing in the road.
