Hazardous Drainage Grate on Stanley at Isabel in Livermore

The drainage grate in the bike lane at the intersection of Stanley Blvd. and Isabel has parallel bars without cross bars. As I was coming around the corner from Isabel, making a right turn on Stanley, I fell right through. I was thrown forward and hit my chin (nearly breaking my jaw - the mandible) and broke one finger and sprained the others as I fell. I've attached a photo of the grate, taken the day after I went to the ER. All of the other grates on Stanley have cross-bars to prevent bike tires from falling through. In fact, a Google search of the intersection shows that the grate was previously covered and marked with warning pylons. However, it was completely open with no markers the day I fell through. UPDATE 3-4-15: Submitted via Livermore's citywide online form, as well as a personal email to Public Works, complete with the photo (thanks!) as well as a call-out regarding the serious injury that resulted from the deficient grate.
