Members of the Arvada City Council and city staff donated time Wednesday to clean up dog poop.
Last week, parks crews placed 600 orange flags in the south field of the Arvada Center - one for every pile of dog poop - to raise awareness about the problem.
Officials said, "it's gross, it's bad for the environment and water quality, it spreads disease, and it's being a bad neighbor!"
You can be fined up to $999 for not picking up your dog's waste.
"Please, be responsible dog owners and pick up after your dog! Pass it on!" officials said.
