Bicycle Austin forum

There is an unfortunate pile of sand in the bike lane at Whitis and 30th that has been there for quite some time. Unfortunately, while riding last night, I forgot about this sand and my bike slid sideways causing me to break my arm. I have learned that one of my friends slipped on it over a year ago, she dialed 311 to complain but nothing was done. I have also complained via 311.

Do we as cyclists have any legal rights to a clear and safe bike lane? Who is responsible for cleaning this up and why wasn't it done? It seems pretty easy and cheap to fix.
