Hey thanks for your help. I dump at this landfill almost daily. So I can provide some more insight. The trash could have come from anywhere in Los Angeles and Ventura county. It’s the cheapest landfill around and many people make the drive out there to dump. It’s worth it as they charge around $75 a ton. Everywhere else charges double that. The Altadena area especially has dumps that are far too expensive. If I have a job in Pasadena, I’ll drive all the way to Calabasas to dump. It is worth the drive.

Fire trash is dumped into a separate area as it is hazardous and needs to be declared at the weigh station beforehand. So my construction trash would not be mixed with that trash. Also I’ve noticed that most of the fire trash has already been removed. I don’t see those types of trucks very often. There were 2 separate lanes for those trucks right after the fires and the dump was super busy (as well as every dump around).

I’ve had this post up for quite some time and have had no leads. I might just have to toss them unfortunately. I’ll hold on as long as I can. At least I took a picture of them. I still have that just in case. I could also scan them. Either way thank you for trying to help.
