Most likely, the downspouts do not extend directly into the storm drainage system in the street. They could go into a square area drain in your yard as mentioned above. But, they could also go into a pipe that terminates near the curb in your front yard, with a pop-up plastic drain device. The pop-up drain will have a round top that floats up when the pipe fills with water. Either way, the area drain and/or the pop-up drain could be buried. Also, mentioned above.
