Milwaukee Flooding Submerges Underground Parking Garage at Potawatomi Casino

Historic rainfall that struck Milwaukee over the past weekend caused extensive flooding of the parking complex and hotel at Potawatomi Casino. Floodwaters poured into the underground valet level where attendants had been storing guests’ vehicles. Dozens of cars were effectively lost along with their owners’ personal belongings, turning what was meant to be a casino hotel stay into a disaster for those who had left their vehicles underground.

Cars Retrieved, but Little Left to Save

Potawatomi management announced a procedure for returning vehicles from the flooded valet garage. However, guests arriving to collect their cars are finding conditions far from hopeful. Interiors are coated in mud and mold, electronics show no signs of life, and insurers are describing the condition of the vehicles with one short, unforgiving term: total loss.

Disgruntled guests believe the owners bear significant responsibility for what happened, as Potawatomi Casino has long gone without renovation. Many operators are now investing in the upgrade of land-based casinos — it has been reported, for instance, that Grosvenor Casinos is investing in the renovation of two venues in Birmingham. Against this backdrop, the incident in Milwaukee appears especially telling.

What Happened in the Casino Garage

According to Potawatomi’s official account, the intense precipitation brought shallow water onto the first level of the multi-story parking structure and several feet of water into the underground valet area. It was this lower level — designated for vehicles accepted from hotel guests by valet attendants — that bore the brunt of the disaster. The upper floors of the garage sustained significantly less damage.

How Owners Can Retrieve Their Vehicles

The casino published a clear set of procedures for vehicle retrieval. The key conditions are as follows:

• Access opened on Thursday, August 14, starting at 9:00 a.m.
• Vehicles have been moved to the parking area at the southwest corner of the casino building, near the employee entrance
• The retrieval area is open from 9:00 a.m. to 6:00 p.m.
• Owners must present a photo ID along with one of the following documents: a valet ticket, vehicle registration, or vehicle title
• Insurance adjusters and tow truck drivers are required to present a business card and the VIN of the vehicle being serviced

Timeline of Events from Check-In to Vehicle Retrieval

On Saturday, a number of guests checked into the casino hotel. In the early hours of Sunday morning, water surrounded the complex and rushed into the underground valet lot. On Wednesday, some owners were able to see their vehicles for the first time. On Thursday, the casino officially launched organized access to vehicles at a designated area.

Young Mother Lost Everything That Was in Her Car

One of the victims, 22-year-old Dadriana Gibson, was staying at the Potawatomi hotel not for leisure. Milwaukee city inspectors had found foundation problems in her apartment and ordered an urgent relocation. Gibson, the mother of a one-year-old son, packed her child’s belongings and personal items into her car and checked into the hotel on Saturday evening while searching for a new place to live. A valet attendant accepted her vehicle and parked it underground.

From her room window, Gibson watched the water rise around the building. When she finally reached her car several days later, she found brown sludge, mud, and mold inside. “I lost everything. All of my baby’s things were in that car,” she said.

The Depth of the Flooding Remains Disputed

The casino’s official statement references several feet of water in the underground valet garage. However, according to Gibson, a parking staff member told her the water level reached approximately 8 feet (about 2.4 m). The discrepancy is significant and may affect subsequent proceedings with insurance companies.

Dozens of Cars Outside the Casino and Life Without Wheels

As of Thursday evening, dozens of vehicles remained on the lot outside the building. Most appear to be a total loss and will likely be written off. In addition to the cars themselves, owners have lost property that was stored inside.

For Gibson, losing her car has meant daily expenses of $30 to $60 on Uber to commute to and from her job at a nursing home. “My car means everything to me right now, especially since my baby is sick. He has heart and lung problems and we go to the doctor often,” she said.

The Casino Called the Situation Unprecedented, and iGaming industry data supports that characterization

In its statement, Potawatomi thanked guests for their patience and emphasized that ensuring the safety of guests and staff had been the top priority. Management described the situation as an “unforeseen flooding” and an “unprecedented event.”

Incidents of this kind deal a particularly damaging blow to the reputation of land-based casinos, especially against the backdrop of growing pressure from the iGaming industry. Online platforms featuring live dealer games have drawn a significant share of the audience in recent years, and every scandal surrounding physical venues only accelerates that trend.

The scale of virtual entertainment’s popularity becomes clear when browsing dedicated portals. It took no more than a visit site reviewing the live game Lightning Storm by Evolution to see that the popularity of certain online shows is already on par with hit video games. Live formats allow players to interact with real dealers from anywhere, and for many that removes the last argument in favor of a trip to a land-based casino.

When the convenience of online casinos is compounded by stories of flooded parking garages and lost property, the audience’s choice becomes even more predictable.

Insurance Responses Have Yet to Arrive

The next step for those affected is engaging with insurance companies. Gibson said a casino representative provided her with Potawatomi’s insurance contact number. She called, but had received no response by the time of publication. Vehicle retrieval continues on the established schedule, with owners and insurance representatives processing paperwork and arranging towing, while some of those affected are still waiting for any response to their inquiries.
