The entire 400 and 500 blocks of Superior Dr street and sidewalks were marked up for underground lines last week. It is understood that this is necessary but it would nice if residents weren't left with the aftermath for months until the paint fades. Does the city have ways to clean up graffiti, in this case institutional graffiti? Also, if there is not already codes to handle it, please refer to the town board to require contractors requiring the markings to clean them up after work has been completed. Thank you
