As of today, the estimated amount of debris collected related to the late spring storms stands at 158,113 cubic yards, or 79 percent of all estimated debris to be picked up, after 25 days in operation.  

Why trucks pick up some debris but not all 
Both City trucks and contracted trucks are picking up the debris—the City BABIC trucks pick up small piles of vegetative debris; large limbs and piles are left for the larger semi-trailer-style contracted trucks.  

When trucks can’t collect due to obstacles 
The trucks need room for their large mechanical arms to operate, as well as room to simply move through the street. If cars are parked on the street near debris piles, this prohibits the truck from picking up those piles; same for if the debris piles are located underneath low-hanging tree limbs (see photo). In those cases, the truck will move on and attempt to collect on another day. 

Why collection is taking more than a month 
The amount of debris left from the May 28 storm was equivalent to 3.77 times what is typically picked up in Richardson in an entire year. While it seems like progress is slow, the amount of debris cleaned up is occurring very quickly due to the use of specialized heavy-duty vehicles designed for this type of work.
