SAFE (Streets Are For Everyone) is doing volunteer bike-lane (plus) clean-up events. Report places where bike lane clean-ups are needed via their form
If you're biking somewhere and it looks like these plenty of debris/trash/etc. so it's in need of a clean-up, report it via SAFE's online form https://docs.google.com/forms/d/e/1FAIpQLSfl1MgHzVZsxL6JUP_q2v__5f8y2HgmlqyWqdM9woXgPbtTZg/viewform
