Once per year in the spring, Cottage Grove has it's annual Spring Clean Up Day. You are welcome to bring your unwanted items, have it unloaded from your vehicle by the Public Works Employees and be on your way. There is usually a very long line on this day to drop off your junk as I've seen from experience. It's well worth the wait to get rid of items you cannot throw into your regular garbage. There is of course a small fee for most items, but nothing that wont set you back too much.
