Comments:
During this reporting period, we had one project that required a contractor to repair/replace bridge planking on a pedestrian/bike bridge – Wilkie
Way Bike Bridge Project. We have language requiring proper capture and disposal methods in the contract, and our inspector monitored them to
make sure they followed it. All construction debris was hauled off-site. Graffiti removal continues to be done in-house by staff trained on proper
disposal of wastes; however, no graffiti removal occurred near waterbodies.
