The City of San Jose offers an app called San Jose Clean. It allows users to report litter, illegal dumping, graffiti, and maintenance problems in city parks. The app guides the reporter through the steps, of uploading a photo of the problem, tagging it with GPS coordinates, and including a written description. The user is invited to include contact information for updates on the problem.

The app is available for iOS and Android.

If you don't have an iOS or Android device, you can also report graffiti by phone or email.
