The city I live in has the same policy. They only pick up trash in city provided roll carts. If the cart lid isn’t closed or trash stacked on top of the lid it is not picked up. Bags on the ground are not picked up.
The town I live in just started city provided roll carts for trash pickup. A customer had 3 sizes to choose from 35, 65, and 95 gallons. The 65 gallon was the default size. For the first couple of. months you were able to change sizes with no extra charge for the switch. I’m stunned how many people in my neighborhood switched from 65 ot 95 gallon carts. Some people even pay for two 95 gallon carts.
I got an e-copy at Amazon a couple of years ago.
