If the debris from the side of road is not picked up, it would go into storm drains, which could also cause flooding if they are clogged.
Having street sweepers in cities was a part of the Water Quality Act of 1987, and that's when San Antonio created the Storm Water Management Program that is now run by the Public Works Department.
