Tucson Department of Transportation Prepares for Summer Thunderstorm Season - Initiates Operation Splash

Protecting the traveling public on City streets during Tucson’s summer thunderstorm season is the objective of the Tucson Department of Transportation’s (TDOT) Operation Splash campaign. As weather patterns shift to bring moisture into Tucson, crews from TDOT’s Streets and Traffic Maintenance Division are delivering barricades to hundreds of dip crossings throughout the City.

On Monday, June 4, 2018 through Friday, June 8, 2018, at about 6:30 a.m. each day, TDOT crews will deliver more than 500 barricades to approximately 150 dip crossings throughout the City.

For the third consecutive year, TDOT will once again assist residents concerned with flooding by distributing free sand bags beginning Wednesday, June 13, 2018. TDOT will distribute free sandbags in the north parking lot of the Tucson Rodeo Grounds, 4823 S. Sixth Avenue every Wednesday from 4 p.m. to 8 p.m. until the Operation Splash Program concludes in mid-September.

A self-serve sandbag site will open on Monday, June 11, 2018 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 TDOT. 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, TDOT 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. Crews also barricade dip crossings that are flowing with storm water.

All low-lying areas in the City of Tucson are subject to flooding during the summer thunderstorm season. During Operation Splash, City crews are on call day and night to assist with placing barricades at flooded washes and dip crossings. 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, Street and Traffic Maintenance crews begin evaluating conditions of the roadway and remove any accumulation of hazardous debris.
