I have noticed for the last few months that yard waste crews are more apt to not pick up branches if not in paper bags or in personal yard waste cans. You are still allowed to place branches in small piles at curb the day prior to pickup. You should have small piles that crews can pick up by hand, and are spaced out along the curb. The crews should pick them up. The problem is if it is single pile or limb they just drive past it more likely than not. Lazy? Blind? Combination? I am not sure. I would suggest you report to 311 each time this happens. I do know they have been told to pick this stuff up. I have a contact from serving on Mecklenburg Waste Management Advisory Board for the last 9 years that is with City of Charlotte Solid Waste. I have been making her aware and she has sent crews back out the next day to pick up missed piles.
I have seen some locations the trucks have driven past for over a month!
This has never been an issue until the last few months! I have lived in Madison Park for decades.
With the addition of paper bags the job should be a little easier overall now than in the past, so not sure why they just don't bother to stop and pick up these small piles of limbs, branches placed at curb for pickup un-bagged!
