tenant keeps junk cars and trash all over the property got county violation ticket

[Gp G.]

,I have tenant who is troubling for weeks. He created lot of issues saying mold in the property recently. PM gave him 60 days notice to vacate few weeks back. I am waiting for those 60 days to complete as soon as possible
Attached is the letter I received from county today as this tenant keeping junk cars and trash all around the property even after informing him multiple times. I emailed this letter to my PM as well. Please advise what steps I need to take to avoid fines or imprisonment as stated in attached leter.

Attached is the picture of the junk cars and trash he kept all over the property
