While Iowans rejoiced over spring-like weather this week after a long, brutal winter, flooding caused by rapid snowmelt and heavy rains has threatened communities across the state.

Iowa weather services have been reporting higher-than-average risks for major flooding this spring since late February, and many outlooks have only increased within the last week, according to the Des Moines Register. The risk is most pronounced along the Mississippi River, where a Quad Cities survey found the risk of flooding through May to be 95 percent last week. The National Weather Service says flooding in the Quad Cities could break records.

The National Weather Service issued a flood watch Wednesday morning that will last until at least this evening across most of the state. In some areas the watch will extend into next week. Below is information on flooding and alerts throughout the state as of this morning.

East

  • Major flood stage was reached in Waterloo, Maquoketa and DeWitt as of Thursday morning. Moderate flood stage was reached in many areas Wednesday, including Kalona, Atkins and Augusta (IFIS).
  • Yesterday, Cedar Rapids expected a “moderate flood stage” when the Cedar River crests early next week. Officials said this should be fairly insignificant for residents. The city had already reached moderate flood stage as of Wednesday night (Gazette/IFIS).
  • An ice jam raised alarm in Ottumwa Wednesday morning, though it only caused minor agricultural flooding (Des Moines Register).

Central

  • Squaw Creek in Ames reached major flood stage Wednesday afternoon. As of Thursday morning, all areas were at or below moderate levels (IFIS).
  • An ice jam collapsed a bridge in Johnston Wednesday evening. The trail leading to the bridge had been closed prior to the collapse (Des Moines Register).
  • Des Moines Public Works closed parts of George Flagg Parkway and Fleur Avenue. These could remain closed for days (WHOtv).
  • An ice jam in the Raccoon River flooded rural communities in Dallas County (Des Moines Register).

West

  • Western Iowa was hit worst of all. As of Thursday morning, eight communities from north to south were at major flood stage (IFIS).
  • The Boyer River in Hogan and the West Nishnabotna River near Avoca reached major flood stage Wednesday afternoon. A Red Cross station was set up in Avoca for those displaced from homes (kwbe/IFIS).
  • Underwood in Pottawattamie County lost function of its sewer lift system Wednesday. Residents were asked to stop flushing toilets temporarily (kwbe).
  • Harrison County Emergency Management ordered a partial evacuation of Missouri Valley Wednesday night. As of 9:20pm, 2,600 people were underwater (Des Moines Register).
  • Several roads have been closed as well. Check 511ia.org for current closures. 

Take care around even shallowly flooded areas, especially when driving. Remember that while newly-purchased flood insurance takes 30 days to go into effect (and will therefore not help you this week), Iowa’s flood season has only just begun.

Julia Poska | February 15, 2019

A tiny Iowa town may soon get an unprecedented expansion. Diligent Development wants to build Iowa’s first “agrihood” on 400 acres just south of Cumming, bringing food and outdoors living to the center of a relocalized community.

According to the Des Moines Register, which featured Diligent’s plans yesterday, over 200 such communities already exist elsewhere in the U.S.. Agrihoods bring the country closer to the city, integrating food production and nature into suburban areas without spreading neighbors too far apart or committing them to a fully rural lifestyle.

The Register reports that the Cumming agrihood could bring over 1,800 new residents into the 400-person town with mixed housing; apartments, condos, townhomes and single-family homes would all surround a large organic vegetable farm.  Farmers would sell through subscription-based services or at local stands, and residents would maintain smaller community gardens as well.

Residents would have easy access to parks and green space too, as the Great Western Trail. The community would also feature a craft brewery, an orchard and retail space.

Cumming is 20 minutes southwest of Des Moines, close to Interstate Highway 35 and Iowa Highway 5. The development would cost about $260 million and is awaiting approval by the Cumming City Council.

Water quality has been a growing concern for many Iowans in recent years, primarily due to nitrate runoff from agricultural fields frequently exceeding the EPA’s safe drinking water limits. A safe drinking water symposium will be held next Thursday and Friday, September 21 and 22 in Des Moines to unpack this issue and many others.

Challenges to Providing Safe Drinking Water in the Midwest” will feature Iowa-based and nationally-recognized speakers and discussion panels related to local, regional and national water quality issues. A few of the topics to be discussed are the Health Impacts of Nitrate in Drinking Water, Drinking Water Treatment Concerns, New and Emerging Drinking Water Threats, and Communicating with the Public on Drinking Water Issues.

The one-and-a-half-day event is co-sponsored by several centers at the University of Iowa, Drake University, the University of Northern Iowa as well as the Iowa Association of Water Agencies, and the Central Iowa Drinking Water Commission.

The event, which will be held at the Drake University Shivers Facility, is open to the public. Additional information regarding agenda, registration, hotel, and parking is available at https://cph.uiowa.edu/ehsrc/drinking-water-symposium-2017.html.  Alternatively, call (319) 335-4756 to speak with an organizer.

What: Challenges to Providing Safe Drinking Water in the Midwest: A Symposium

When: September 21 from 8 am to 5 pm, September 22 from 8 am to 12 pm

Where: Drake University, Shivers Facility, Des Moines

By now it’s common knowledge that as greenhouse gases continue to accumulate in our atmosphere, intensely high temperatures are likely to occur more frequently.

But Climate Central, a climate research and news organization, has developed a way for residents of the continental U.S. to see exactly how much their communities will be affected. The interactive tool allows users to type in the name of their city or town and view the average number of days that will exceed specific temperature thresholds in 2050, 2075 and 2100.

The analysis includes data for nearly 30,000 cities and towns of various sizes from across the continental U.S. Each graph provides two possible outcomes: one in which greenhouse gas emissions continue as usual and one in which they are moderately curtailed.

Researchers based their projections on aggregated data from 21 global climate models.

At present, Des Moines experiences an average of zero days per year when the actual temperature is above 100 degrees Fahrenheit. According to this study, the city will likely see 15 days annually that exceed the temperature threshold in 2050 and up to 30 per year in 2100.

This year is on track to be the hottest year ever, followed by 2016, 2015, and 2014, respectively.

Two Iowa mayors join 1,200 U.S. leaders committed to the Paris Climate Agreement

More than 1,200 United States governors, mayors, businesses, investors, and colleges and universities released a statement yesterday titled “We Are Still In,” declaring their continued support of the Paris Climate Agreement.

The climate declaration serves as a response to President Trump’s withdrawal from the Paris Climate Accord last week. The declaration reads, The Trump administration’s announcement undermines a key pillar in the fight against climate change out of step with what is happening in the United States.”

The businesses and investors speaking out for climate action include 20 Fortune 500 companies that generate $1.4 trillion in revenue annually. Participating city and state leaders collectively represent 120 million Americans ranging from New York City Mayor Bill De Blasio to Palo Alto Mayor Greg Scarff.

Des Moines Mayor Frank Cownie and Dubuque Mayor Roy D. Buol are among the signatories. Cownie said in a written statement, “The recent action by the White House to withdraw from the Paris Agreement does not stop Des Moines’ efforts in advancing our own efforts on climate change. Cities like Des Moines will continue to work to make our communities more sustainable places to live.” Other statement endorsers from Iowa include state Attorney General Tom Miller; J. Bruce Harreld, president of the University of Iowa; Raynard Kington, president of Grinnell College; Paula Carlson, president of Luther College.

The City of Des Moines adopted a target to reduce greenhouse gas emissions by 80 percent by the year 2050 in 2016 as a part of the City Energy Project (CEP). CEP is a coalition of cities working to reduce energy use and curb emissions from buildings in urban areas. The city’s Parks and Recreation Department has been phasing in hybrid vehicles and utilizing alternative fuels like biodiesel to power its fleet as well. In an  interview with the Des Moines Register, Cownie said, “We’re trying to look at every part of our operation, including the work we do with business partners and neighborhood where they can afford it.”

Cownie is in good company. Since the White House withdrew from the Paris Agreement, 17 governors have released statements in support of the accord, 13 governors formed the U.S. Climate Alliance and 211 mayors have independently taken on the climate action goals outlined in the Paris Agreement for their communities.

The “We Are Still In” press release concludes, “Today’s statement embraces this rapidly growing movement of subnational and civil society leaders, by announcing that not only are these leaders stepping forward, they are stepping forward together.”

ISU researchers develop decision-making tool for sustainable cities

Researchers at Iowa State University (ISU) and the city of Des Moines are working together to develop a decision-making tool that could revolutionize the way cities tackle climate change and social issues.

Ulrike Passe, associate professor of architecture and director of ISU’s Center for Building Energy Research, is the lead faculty researcher. Passe said, “There’s so much unrelated data available — from census and economic information to policy studies and weather records — but it needs to be merged into a useable model.” Passe added that city planners and officials need to have “a data-based tool that helps them decide how to allocate resources for conservation measures like tree planting and storm water management.”

Passe’s team of 16 researchers from over a dozen disciplines is working closely with Scott Sanders, Des Moines city manager. Sanders said, “The creation of this this decision-making system will provide staff access to an amalgamation of big data, which they presently have no way to effectively evaluate, that is a critical component to the future of successful and resilient cities.” Sanders noted that citywide interest in sustainability is on the rise, he said, “The demand far outweighs the city’s ability to provide all of the required and desired improvements within its current budget constraints. The need for a data-driven process and policy to help assess and prioritize the city’s investments has never been higher.”

The project is focusing its efforts on communities in east Des Moines such as Capitol East, Capitol Park and MLK Jr. Park. Linda Shenk, associate professor of English at ISU, is also involved in the study. She said, “We focus on marginalized populations because they are the most vulnerable to the effects of climate change due to limited resources, yet the most difficult for cities to reach and engage in data collection.” For her part, Shenk has been discussing climate change and brainstorming local solutions with neighborhood groups and high school students. Meanwhile, other researchers in the neighborhoods are gathering data about how citizens interact with their city, communities, and homes using computational thermal-physical models.

Other ongoing projects include a tree inventory in the Capital East neighborhood and energy efficiency research through controlled experiments at ISU’s net-zero energy Interlock house located at Honey Creek Resort State Park. The study’s goal for this year is to compile data about human behavior related to energy use. Moving forward, Passe said, “Our objective is to create decision-making support systems that will help cities and their residents translate this research into actions — new policies, incentives for individual behaviors and community resilience.”

This week’s On The Radio segment covers Des Moines symposium, “Iowa’s Drinking Water: Could Flint Happen Here?”

Transcript: Des Moines event examines water quality and infrastructure in Iowa

After unsafe lead levels were detected in drinking water in Flint, Michigan, an upcoming event aims to educate Iowans about water issues in the Hawkeye State.

This is the Iowa Environmental Focus.

The University of Iowa Public Policy Center and the UI’s Center for Health Effects of Environmental Contamination have organized a symposium in Des Moines scheduled for this weekend entitled “Iowa’s Drinking Water: Could Flint Happen Here?” The all-day event will include panels of water experts from various agencies and institutions including the University of Iowa, Drake University, the Iowa Department of Natural Resources, and the U.S. Environmental Protection Agency.

David Cwiertny, an associate professor of civil and environmental engineering at the University of Iowa, helped to organize the event.

David Cwiertny: “With Flint being in the news we wanted to organize a symposium that would address, “Could such a crises happen here in Iowa?” We also wanted to make sure we thought about issues beyond just lead contamination that might also be relevant in Iowa so we’ll be talking about agriculture and its impact on drinking water as well as challenges beyond nitrate and what’s going on in Des Moines.”

The event is open to the public and scheduled to begin at 8 a.m. on Friday June 17 at the Community Choice Credit Union in downtown Des Moines.
