The city of San Francisco followed Hamburg, Germany by painting walls near bars and areas with a high homeless population with hydrophobic paint. The campaign is in response to complaints about the homeless community and party-goes urinating on walls…which was both costing the city for cleanup and leaving business owners and bar goers complaining. The “Hold It” campaign has signs in several languages instructing people to please not urinate at that location, and if they do, their shoes may suffer. “The idea is they will think twice next time about urinating in public,” said Rachel Gordon, a spokeswoman for the city’s Public Works Department. According to the BBC article, public response has been excellent, with many requests for more hydrophobic paint in different areas. Also, in response, the city is installing more public restrooms.
