There are like 6 places to drop off bulk trash. You just can't take construction trash to them all. You have to go to the northwest transfer station if you specifically have construction trash.

I have trashed yes, tables, chairs, scrap wood, and all sorts of other things at 2 or 3 of the drop off stations and it cost $0. Just had to show a city address.

So taxes cover a vast majority of your trash.

Illegal dumping is often from shitty contractors who don't want to pay for their construction waste. The city charges $67.50/ton of trash for construction specific trash.
