It's an eyesore that San Jose residents want to get rid of and in the past two years the city has made great progress in eliminating its graffiti problem.
In 2011, the city hired Graffiti Protective Coatings to cleanup. It has also asked the public for help. Residents can use an app called San Jose Clean.
"They take a picture of the graffiti, send the location and then that's how I get my work orders," said Julio Bonilla of Graffiti Protective Coatings.
But when it comes to freeways, the city has no authority to paint over the graffiti, only Caltrans does. The same applies to the railroads controlled by Union Pacific.
"Properties that we can't control like Caltrans properties and railroad properties are horrible. And many cases that take a long time to get fixed. So it's very frustrating to us because of all the work that we put in on San Jose property," said Mayor Chuck Reed.
San Jose officials are pushing Caltrans and Union Pacific to invest in access barriers that will keep taggers out.
