Data from the U.S. Army Corps of Engineers are supporting northeast Missouri residents' suspicions that overbuilt levees along the Upper Mississippi River have led to increased flooding for vulnerable communities. 

The Corps of Engineers last spring surveyed levee heights in the Rock Island District, which runs from Keokuk, Iowa, to Thebes, Illinois, and discovered that 40 percent of the levees exceeded regulation. The federal agency released a model at the end of January that measured the impact the overbuilt levees have on river flooding. The model, however, requires an experienced engineer to operate, so environmental advocacy group American Rivers hired a consultant to do so this month.

St. Louis-area residents may see a new fee on their sewer bills at the beginning of 2020. That's because the Metropolitan St. Louis Sewer District wants to impose a new fee to help fund efforts to resolve flooding and erosion issues in its service area. 

In a proposal MSD submitted to its independent rate commission on Monday, the district estimates the cost of resolving the region's stormwater runoff issues to be $560 million. The plan would charge an average of $2.25 per household per month, or $27 per year. The more surface area a property has that can't absorb water, the higher the fee. According to MSD projections, the new fee would generate $30 million per year for 30 years.

St. Louis County is one of the highest-risk counties in the United States for flooding in schools, according to a Pew Charitable Trust report released Tuesday.

The 100 most at-risk counties identified in the report have 6,444 schools educating nearly 4 million students. Three of those are in St. Louis County, and one of them, Eureka High School, has flooded twice in as many years.

Communities along the upper Mississippi River have seen a major uptick in heavy rains and flooding in the last decade.

Residents, environmentalists, engineers and government agencies agree that they need a coordinated strategy to manage flooding. That could be particularly important in coming years, as scientists predict that climate change will likely bring more heavy rain to the region.

Nancy Guyton has lived by the Mississippi River her entire life. She and her husband farm in Annada, a small town on the Missouri side of the Mississippi River. She knows that growing crops on the floodplain comes with some risks.

The Guytons’ farm, about 65 miles north of St. Louis, endured major floods along the Mississippi in 1993 and 2008. But since 2008, she’s noticed more flood events.

Two months ago, retired physical education teacher and Eureka resident Sharon Wasson spent four days trying to keep sewer water from entering her basement. An armada of blower fans covered the floor. Members of Eureka High School’s football and wrestling teams packed the place, pumping water out of Wasson’s house.

Two months later, the basement where she once spent most of her time is still a work in progress. Having dealt with the major flooding in May and in December 2015, Wasson is conflicted about staying in Eureka.

St. Louis-area residents who are recovering from flooding can get help with cleaning up, filing insurance claims and finding counseling all in one place in the coming days.

Local, state and federal disaster specialists still are assessing the size and scope of damage throughout Missouri from the flooding and storms. Gov. Eric Greitens said Wednesday it's part of the state's application seeking a federal disaster declaration.

"I'm just happy the residents are back in their homes."

That is how Valley Park Mayor Mike Pennise summed up several days of battling the rising Meramec River, west of St. Louis. He issued a mandatory evacuation order for part of the city of roughly 7,000 last week as residents and emergency officials prepared for a second round of major flooding in roughly a year and a half.

This week, residents of the St. Louis metropolitan area have been doused with several waves of heavy rainfall, resulting in flooding across the region.

South of St. Louis, Arnold, Fenton, Eureka and Pacific have been particularly hard hit. Similar areas were flooded in December of 2015.

While the Meramec River, which was responsibile for the flooding in that area has crested and is receding, the Missouri River at St. Charles is cresting today and the Mississippi River from Alton down will be cresting from today through tomorrow.

Sharon Wasson, a Eureka resident and retired high school physical education teacher, treats her basement as her sanctuary. It’s where her office is, where she watches the news and where she decompresses after a long day.

But severe flooding this week along the lower Meramec River has transformed her basement into a source of stress.

Updated May 4 at 7 p.m. with information about West Alton — Officials with the Rivers Pointe Fire Protection District are urging residents east of Highway 67 in West Alton who plan to evacuate, particularly those who are elderly or have a disability, to do so immediately. Those planning to ride out the flooding, officials said in a Facebook post, should secure provisions.

A second round of heavy rain rolled through the already soaked and flooded St. Louis metro area Wednesday, leading to longer school closures and heightened worries among affected residents.

Up to 4 inches of rain is expected through Thursday evening, further frustrating travelers who rely on two major interstates in the area. Even so, rivers in the area are forecast to crest Wednesday.

The Meramec River is expected to crest at 40 feet on Wednesday, posing a threat to low-lying communities, including Valley Park, Eureka, Fenton and Kirkwood. 

As water levels rise along the same communities that were badly impacted by flooding in early 2016, some local environmentalists say that levees are responsible for the severe floods residents in the St. Louis area have experienced in recent years.

Updated May 1 with new road closure information - Rising rivers in the St. Louis area that are already threatening homes and businesses will also cause major traffic headaches for at least the rest of this week.

More than 70 roads have been closed in the area due to engorged rivers and streams. (See a complete list here.) Officials say more will be added to the list this week. That includes Interstate 44, which will close in both directions at Route 141 Monday night. Missouri Department of Transportation engineer  Tom Blair says it will mark the third spot on the interstate to close since the heavy rains hit the state this past weekend.

Walter Wolfner was not prepared for the impact that last year's heavy rains would have on his business, the Riverside Golf Club in Fenton. 

"The velocity of the water was so great that it picked up sand from the Meramec River and deposited it on the golf course," Wolfner said "I mean, we'd never seen things like that before." 

While he managed to clear off all the debris from the golf course, which is adjacent to the river, it took three months to rebuild the clubhouse, which had to be completely gutted and rewired. 

The state of Missouri estimated that more than 7,000 structures were damaged by last winter's heavy rains. Like Wolfner, cities and many residents along the Meramec, Missouri and Mississippi rivers have been trying to recover and rebuild.

A $9 billion bill in Congress that could improve waterway navigation and water systems in Missouri is a step closer to being signed into law.

Last week, the U.S. House of Representatives voted 399-25 to approve the Water Resources Development Act — in a rare show of bipartisan support. The Senate passed its version of the bill earlier last month. 

The Water Resources Development Act, authorized every two years, gives the green light to the Army Corps of Engineers to improve navigation, water quality and work on other water projects.

The Valley Park levee in St. Louis County may have been built too high, according to new findings from a private engineering firm hired by a conservation group.

The report by Pickett, Ray and Silver Inc. commissioned by the Great Rivers Habitat Alliance, concluded that four locations along the levee exceeded the maximum height allowed by the U.S. Army Corps of Engineers, which is 435 feet above sea level. One spot surpassed the standard by 8 feet.

The "cloud burst" that drenched a mid-section of St. Louis County with nearly four inches of rain early Monday morning is only part of why local streams and creeks swelled their banks, flooding businesses and several busy streets.

Forecasters called it a 25-year rain event, but similar flooding took place just eight months ago and to many county residents it's also reminiscent of flooding in 2008.

In the months after floods swept through his hometown of Fenton  just after Christmas, Scott Bayliff and 16 crisis counselors from the mental health center Places for People were on the ground to help.

“We ask them how they’re doing, assess them for the signs of trauma, signs of depression, worsening sleep, anxiety, increased substance use,” Bayliff said. “We’re here to listen. We knew a lot of people were just overwhelmed, and they just needed someone.”
