Navigating Climate Challenges in the Quad Cities

April 16, 2024

The Mississippi River communities, known as the Quad Cities of Iowa and Illinois, are susceptible to flooding from various sources, including the Mississippi River, Illinois’ Rock River, and urban runoff. As climate change intensifies, extreme weather events such as severe flooding, wildfires, droughts, and extreme heat are expected to increasingly affect the region’s quality of life. An assessment conducted by the NWF,  PRN and DPI utilized climate models to evaluate potential outcomes under different emissions scenarios. The objective is to provide Quad Cities residents with insights into potential climate change impacts and to propose strategies for fostering a healthier and more resilient future. Climate change will affect all residents of the Quad Cities, with vulnerable populations—such as those with lower socioeconomic status, Black, Indigenous, and People of Color (BIPOC), renters, individuals experiencing homelessness, immigrants, and people with disabilities—being more likely to face significant health risks from heat and substantial property damage from flooding. Input from various Quad Cities stakeholders was instrumental in shaping the assessment, ensuring that the proposed nature-based solutions were aligned with community concerns and knowledge. These findings serve as a foundation for resilience discussions within the Quad Cities.

About the Quad Citites

The Quad Cities, home to nearly 400,000 residents in southeastern Iowa and northwestern Illinois, lie along the Mississippi River at its confluence with the Rock River. Relying on the Mississippi for manufacturing, commerce, transportation, and recreation, the area is highly vulnerable to flooding, evidenced by record heights in 1993, 2019, and 2023. Despite this, the region’s natural features, such as creeks, forests, wetlands, and prairies, offer significant benefits for hazard risk reduction and community resilience.

Major Findings

We conducted flood simulations for daily timestamps and 100-year return period rainfall intensities over the Quad Cities to identify regions and land use features at risk. To protect these areas, we implemented innovative combinations of different nature-based solutions. The full report identifies and suggests various nature-based solutions that can be implemented in the region to safeguard against floods.

Stakeholder Engagement

The initial findings of the assessment were presented to stakeholders, including mayors, municipal authorities, and the general public. This engagement facilitated the identification and investment in nature-based projects for risk mitigation, economic enhancement, and wildlife conservation. By providing local leaders and community members, the assessment aims to inform strategies for long-term resilience, with a focus on the most vulnerable populations. Stakeholders, including residents and local leaders, are invited to participate in sessions to review the draft assessment, provide feedback, and discuss implementation strategies.

Live Product Demo

With the help of GIS and Remote sensing techniques, we developed a visualisation platform to demonstrate the areas potentially at risk due to floods in Quad city region. For the visualisation platform, please visit here.
