Prior to 1990, graffiti was found on Caltrans facilities and removed from time to time. It was viewed primarily as a nuisance to be dealt with along with other work. Presently, it commands a great deal of time and resources that are used to ensure the removal of unsightly graffiti. At the same time, the graffiti problems remain with moderate success in abatement.
Caltrans recognizes the importance of quickly removing graffiti in order to discourage further vandal activity. Graffiti removal is scheduled by highway route segments for intensive clean-up. Graffiti that jeopardizes motorist safety, is obscene in nature, or politically-oriented is removed as soon as possible.
Caltrans has been experimenting with new and innovative ways of graffiti removal and prevention. Graffiti that was once seen only on walls is now showing up on overhead signs, retaining walls, bridges and bridge columns. With increasing cost for graffiti removal (which exceeds $20,000/month) and an average of 150,000 square feet of abatement per month, new and innovative methods are being explored.
The following have been used in recent years:
  • The use of concertina wire on heavily targeted areas. Concertina wire is wrapped around the column or end posts as a way of discouraging taggers from gaining access to the overhead signs.

  • Rat Guards, a steel cone personnel barrier, is placed on sign posts to deter taggers from scaling the poles. The guards are being used at heavily tagged locations. The guards are made of smooth metal and are disk-shaped, making it difficult to climb on to the overhead signs.

  • Cobra Shields have been used in the last few years. The shields, which vary in length and width, extend over the front and sides of the overhead signs, making it difficult for someone to reach over and deface the signs.
  • Graffiti is a community-wide problem with both public and private facilities being affected and seriously impairs community appearance and values.
