Protecting the traveling public on City streets during Tucson’s summer thunderstorm season is the objective of the Tucson Department of Transportation and Mobility’s (DTM) Operation Splash campaign. As weather patterns shift to bring moisture into Tucson, crews from DTM’s Streets Maintenance Division have delivered barricades to hundreds of dip crossings throughout the City.
Beginning Monday, June 15, 2020, DTM staff will be on-call 24 hours a day, seven days a week through mid-September. As washes flood, crews will close roadways at dip crossings and washes using the more than 500 barricades that were delivered earlier this month and placed on the side of the roadways, near the crossings.
For the fifth consecutive year, DTM will assist residents concerned with flooding by offering free self-serve sandbags beginning Tuesday, June 16, 2020, until the Operation Splash Program concludes in mid-September. Free sandbags will be offered in the east parking lot of Hi Corbett Field, 700 S. Randolph Way, at Reid Park. This location will be open 24 hours a day, seven days a week. Residents should bring their own shovel. Sand and sandbags will be provided by DTM staff. To accommodate as many residents as possible with sandbags, there is a limit of 10 sandbags per vehicle.
In the event that severe weather is forecasted in the region, DTM staff will initiate Operation Splash and mobilize to monitor dip crossings and washes. By monitoring radar from the National Weather Service in Tucson and the Pima County Regional Flood Control District ALERT System, staff may also begin barricading dip crossings in anticipation of incoming floodwater.
All low-lying areas in the City of Tucson are subject to flooding during the summer thunderstorm season. The goal of the program is to make sure motorists do not enter flooded roadways. Please remind the traveling public that a barricade in place on a roadway is a sign that unsafe conditions exist ahead. After the floodwater recedes, Streets Maintenance crews begin evaluating conditions of the roadway and remove any accumulation of hazardous debris.
