Operation Splash

Operation Splash June 15 through mid-September

Protecting the traveling public on City streets during Tucson’s Monsoon Season is the objective of Operation Splash. As weather patterns shift to bring moisture into Tucson, crews from the Streets Maintenance Division deliver barricades to hundreds of dip crossings throughout the City.
