Other: On January 13th of this year I sustained a fall on the sidewalk on N Washington St. between 6th and 5th street. My shoulder was hurt when I broke the fall and is still sore as of 4/18/16. The fall was caused by ice on the drain cover crossing the sidewalk. The covers on that block are smooth aluminum with no grids for traction. It was covered by clear ice so I couldn't see it. A postal carrier was close behind me and he helped me to my feet. He said those drain covers were a hazard to him as well. I have waited thinking my right shoulder would improve but it has not. What is the city's policy for this kind of injury? I'd prefer not to have to pursue civil litigation to correct this.
