Since the damage seems to be mainly cosmetic, you might consider getting a few repair estimates to see what the cost would be to fix it.
Since the accident was caused by a mistake and not another driver, insurance might not cover it. However, it's still a good idea to contact your insurance company and explain what happened. They can advise you on the best course of action and let you know if they can help with the repairs.
If you're concerned about the legal aspects, especially if the accident happened in a public area like the transfer station, it might be a good idea to consult with a Longmont drunk driving accident lawyer. They can provide you with guidance on how to proceed and protect your interests.
