I have reported this issue--a water meter hole without a cover and ringed in jagged metal--twice on the county report-a-problem website, first over a month ago. They don't seem intent on repairing it. It's right in the middle of the Clarendon Blvd bike lane at Adams street. Sure, in broad daylight it is easy to miss, but hitting it accidentally would not be pleasant.
Does anyone have a contact in the county?
There is also a fair amount of rock in the same bike lane just up the hill approaching Veitch. I have generally found the county addresses this fairly quickly, but this seems like a weird oversight in a very prominent place. Since my worst fall was from hitting a rock, I am sensitive to their presence!
