Heavy rains, flooding impacts KDOT construction

May was one of the wettest months Kansas has seen in recent years. Some parts of the state saw more than 20 inches of rain — more than four times the average amount for some areas. 

Greg Schieber, KDOT Bureau Chief of Construction and Materials said that KDOT is currently working through the impact of severe weather on the 2019 construction season.

"Not only has the severe weather impacted the physical work that can be completed on a project, it is also impacting materials supply for projects including aggregate supply and binder supply," Shieber said.   "We are working with contractors now on prioritizing the projects that can be completed this construction season. KDOT also has initiated discussions on the potential of changing late start dates and delaying some projects until the 2020 construction season."

Shieber said in some situations, the floodwaters are still too high to assess damages, putting construction projects farther behind. As reported last week, the Lewis and Clark Viaduct is one of those projects.

All this additional rainfall only exasperated several rivers that were already full because of heavy snow melt from states farther north. Highways in parts of the state have closed at times due to water covering the surface and that’s not the only problem. This much water has led to delays in maintenance repairs and construction projects across the state.
Joe Palic, KDOT Area Engineer in Marion, is dealing with delays on some construction projects. 

High waters caused K-177 to close between Strong City and Cottonwood Falls last month. 

“The flooding hasn’t been the issue, it’s been the heavy rains that have saturated the job sites and made it tough to work,” Palic said. 

Ashley Tammen, Public Affairs Manager for north central Kansas, also said that for each day of heavy rain means another day lost in highway work as crews work to clean up debris from flooding.

Ron Hall, District Engineer for southwest Kansas, said that weather can have an impact on construction season. “Some projects may take longer to complete, the planned start date for some projects may be delayed,” Hall said. “Schedules and tasks change due the impact of weather events.” 

Delays can also happen because KDOT crews and contractors must spend more time and resources cleaning up debris and tacked on mud on the roadways. 

After the flood waters recede debris can be left behind and KDOT crews work to clear the roads. 

“Pavement can sustain damage from floodwater,” Tom Hein, Public Affairs Manager for south central Kansas said. “Before a highway is reopened, it is checked for damage.” 
Hein also said that while there have been delays on smaller projects, for larger projects it is less of a problem. “It slows down work, but they’ll eventually catch up.”

The heavy rains and flooding have also had an impact on normal maintenance activities across the state, like mowing the right of ways. 

Jeff Romine, Area Superintendent for Wamego, said that there are a couple of reasons why crews can’t mow when the ground is saturated.

Heavy rains help grass grow quickly, unfortunately, all the water received has caused the ground to become saturated, which can make mowing efforts difficult. 

“It is harder on the equipment when it is wet due to the equipment falling through muddy area,” Romine said.  “It also causes the mower to pull harder with the mower getting mud stuck between tires and frame of the machine. Mowing when wet leaves large ruts in the ground and then the grass dies, creating more work because we need to haul dirt in and do some landscaping.” 

Romine also added that if KDOT mowing equipment is damaged, it puts crews even farther behind.

Kansas is expected to receive even more rain this week. Please be patient as KDOT crews work when it is safe to do so. Please be aware of flooding risks and check Kandrive.org regularly for road conditions. Remember if you come across a flooded roadway — turn around, don’t drown.
