Whenever the city becomes aware of graffiti on structures within the city and visible from a public right-of-way, or on city-owned property the city shall give written notice to the property owner that the graffiti should be removed or effectively hidden within 10 days from the date the notice is served. Prior to being cited under this section, the property owner may give the city written authorization to allow the city to remove the graffiti vandalism if the city has a graffiti removal program available to such private property. There is no charge for this service. However, the property owner is encouraged to take all steps possible to remove graffiti themselves. The City is not responsible for matching paint and only has limited colors available.
