Thank you for reporting this issue. We value your concern and would like to further investigate.

This person obviously has nowhere else to go and appears not to be bothering anyone, nor is he breaking the law. Sorry folks but the Western Prom is not the exclusive space of snobbish women of a certain age or the successful gay real estate agents who live along it. Leave the 99%ers alone!

It is indeed illegal for anyone to set up a camp within Portland city limits...
In fact, See Click Fix even has a category for reporting it...

Thank you for bringing this issue to our attention. Police officers and outreach workers will work to locate the people and offer services in hopes of obtaining safe shelter. We will notify the property owner if clean up is required. We appreciate your desire to assist the homeless by bringing this forward..
