Trash Cans Left Out 24/7 365

Is there anything to be done about it? The house sold this year and the new buyers have left their four cans up against the street (no curbs or sidewalks) this entire time since March. Now, these past few weeks, more and more houses in the neighborhood are leaving them out for days past collection. We have no HOA or covenants. Is there anything to be done through the city? Love to hear ideas as to how to tactfully convey that if they can buy really costly houses they can figure a way to get in the cans
