Experience has shown that removing graffiti as soon as it occurs is the best prevention against future graffiti. Whenever you see graffiti please contact the Unified Police Department Graffiti Removal Program at 385-468-9769 or email@example.com. UPD will send someone out to take a photo to document the graffiti and then either remove the graffiti or provide the property owner with paint and solvent if they prefer to remove the graffiti themselves. If someone tags the location again, report it again. It may take two or three times before the vandal gives up or gets caught.
Graffiti is not a prank, it is a crime. Graffiti can be graded anywhere from a Class B misdemeanor for less than $500 in damage to a second-degree felony for more than $5,000.
