The Duluth Police Department and the Life Safety Office are sponsoring a graffiti clean-up in the city of Duluth.

The clean-up will happen on May, 16th, Life Safety inspectors, Officers and volunteers will work on cleaning up graffiti on public spaces, meanwhile, owners of private property are also asked to clean-up any graffiti by the same date.

The DPD is asking that the public report graffiti, call 218-730-5183. Just leave a message at that number and the Life Safety inspectors will add it to their list.

According to Deborah Lamm Weisel, she's the director of police research in the Department of Political Science and Public Administration at North Carolina State University, "an estimated $12 billion a year is spent cleaning up graffiti in the United States. Graffiti contributes to lost revenue associated with reduced ridership on transit systems, reduced retail sales and declines in property value."
