This is Rancho El Dorado Parkway in a housing area of the same name. Here it crosses the bottom of a wide drainage wash that bisects the housing area. The road here is about ten feet (3 m) lower than the rest of the housing area.

Climbing out of this depression on my trike is one of only two bothersome hills I have encountered in Maricopa. The other one, which is much worse, is south of the Walmart store in southeast Maricopa.

I took this picture a few days after a major rain storm. The water, which was about two inches (5 cm) deep and flowing from right to left, deposited sand on the road.

This kind of crossing is cheaper and less trouble to build than it is to build a bridge or construct a berm with culverts.
