university logos

I have one of these logos from the University painted on the sidewalk near the address How can I get rid of it?
I tried using sprinklers that descends from the graffiti, but no, not at all. Any suggestions would help thanks!
The simplest would paint something appears acceptable, or just a solid gray, which matches the color of concrete. The sand should be broader stream of it. Sandblasting is not something to be done by untrained, however. If you're lucky, your city / town the sand Would blow free, if an ordinance that regulates what can be painted on the sidewalk, and if the logo university violates this ordinance.
