A line of cars filled with mattresses, downed tree limbs, chairs, dressers, and rugs could be seen outside a Milwaukee Department of Public Works (DPW) drop-off center on Lincoln Avenue Monday morning. Inside, long dumpsters were being filled with the ruined remains cleared out of roadways and people’s homes after flood waters blanketed swaths of Milwaukee County on Aug. 9 and 10. 

Mayor Cavalier Johnson joined DPW Commissioner Jerrell Kruschke at the dump site to provide updates about the flood response Monday. “Some of these stories that we’re hearing are truly, remarkably sad,” said Johnson, recalling that the first message he received was from his uncle, whose basement was filled with water. From the North Side to the South Side, west towards Wauwatosa and east towards Lake Michigan, the flood quickly engulfed roadways and homes. 

“So my thoughts are with everybody, everybody who is dealing with issues trying to clear out a basement, folks that are enduring power outages, trying to sort out, figure out what to do with the car that has been flooded through,” said Johnson. “We’re working through the process of obtaining some disaster declarations so we can bring the appropriate aid to those citizens who have been affected by the downpour.”

Gov. Tony Evers has activated the Wisconsin National Guard to assist efforts in Milwaukee County. It’s unclear at this time what role, if any, the Federal Emergency Management Agency (FEMA) will have in Milwaukee, as the level of damage needs to meet a certain threshold in order for the agency to be activated. The agency has also been threatened with funding cuts and possible shutdown by the Trump administration. 

Johnson stressed that the weekend storm, which dropped over 10 inches of rain in some areas, was extremely rare. Timmerman Airfield recorded over 14 inches of rainfall. “I think I said the other day that last time something like this happened was about a decade or so ago,” the mayor said. “I certainly hope that a storm like this is not visited upon this city for at least another millennium,” he continued, referring to the weekend storm being called a “thousand year flood.” Kruschke echoed the mayor’s comments about the rarity of the massive flooding over the weekend. Johnson said he’d heard on the news that it dropped essentially “a summer’s-worth of rain” in a single storm. 

Yet research on climate change has long-predicted that Wisconsin would experience increased rain, more intense storms, and greater risks of flooding. In late 2020, a report from UW-Madison and state health workers warned that climate change in Wisconsin would mean more rainfall over fewer days, which would likely cause flooding. The report noted that the weather changes could have a cascade of health effects including heat stroke from increased heat (which also fuels more powerful storms), asthma and insect-borne diseases. In 2021, severe storms downed hundreds of trees in Milwaukee County. The following summer, communities across Wisconsin experienced heat waves, heavy rainfall, high winds and tornadoes over a couple of days, during which time people died from heat stroke, or after being swept away in flood waters during heavy rainfall. By 2022, global CO2 levels exceeded 400 parts per million, a red line which scientists warned would spur even worse effects.

Answering a question from Wisconsin Examiner about the climate trends, Kruschke said that heavy rainfalls have been documented for a long time, and that DPW is relying on historical data. Kruschke said that the city was not prepared for the volume of rain that fell so quickly. As for whether the city can adapt to future weather patterns, Mayor Johnson said, “I’ve been thinking about this since this storm happened.” 

Johnson praised the DPW’s work with the Milwaukee Metro Sewerage District (MMSD) to create infrastructure to capture rainfall when it hits the ground. “So when you look at our construction projects in the city of Milwaukee, when you see bioswales in the street, that’s to make sure that we keep rain out of sewers. That’s to make sure that we keep rain out of people’s basements. When you see MMSD working to make improvements at the parks in order to capture more rainwater there, that’s in order to make sure that we plan for events like this. When folks are going out to install rain barrels in their neighborhood, that’s in order to make sure that we stop things like this. When you have folks out in the city, like they were during this flood event, making sure that the sewer grates are clear so that water is better able to get into the sewers and not in people’s basements, all of these things play a role, and all of these things make a difference.” 

Johnson said the city will continue investing in “green infrastructure” from roadway design to the creation of outdoor classrooms that, in addition to providing experiential learning to K-12 students, also capture rain. “There’s a lot of work that’s going into this,” said Johnson. “I just imagine what this would’ve turned out if we hadn’t done that work over the past number of years. I mean, who knows how many hundreds of thousands or perhaps even millions of gallons of storm water that we were able to capture that didn’t end up in the streets, that didn’t end up in people’s basements.”

The city and county are continuing to assess the full scale of the damage, including how many homes have been affected and people displaced. Monday morning, the Milwaukee County Medical Examiner’s Office stated in response to an inquiry from  the Wisconsin Examiner that there had been no deaths directly linked to the flooding. However, the Milwaukee Police Department’s Harbor Patrol did find a 49-year-old Native American man, identified as Juan Carlos Sierra Campos, who drowned in Lake Michigan on Sunday morning. An investigation is ongoing. 

Kruschke said the public works department  will continue working normal hours (7 a.m. to 3 p.m.), and operate special trash disposal procedures for people clearing out damaged or ruined property. Fees will be waived for city drop-off centers, with the centers operating free of charge until Aug. 17. Drop-off centers will also be open Mondays, when they would normally be closed. The drop-off centers are located at 3878 W. Lincoln Ave. and 6600 N. Industrial Road. 

A small number of street sweepers are out on the roadways, and some communities  are deploying dump trucks and other vehicles to assist. DPW is also offering special pick-ups for storm-damaged material. Among the items that will not be accepted are  explosive or flammable products, propane tanks, large gas appliances, fluorescent light bulbs, wet or oil-based paint and material or vehicles from contractors or businesses.

Libraries, including the West Allis Library, are offering WiFi and computers for people unable to use their own. Cars that were swept away or abandoned during the floods may have been towed to alternate locations so as to not overwhelm the city’s usual tow yards. The city does not have a count of the number of cars towed or abandoned. Overnight parking enforcement will be suspended Monday, Tuesday and Wednesday nights.

Residents are encouraged to avoid wading through flooded areas or standing water. The possibility of contaminated water or hidden debris makes wading unsafe. The Red Cross has also opened two shelters for people who have been displaced by the flooding. The shelters are located at the Washington Park Senior Center (4420 W Vliet St.) and at Holler Park (5151 S. 6th St.).
