Davenport Flood Study 2020

Following the historic floods of 2019, the City formed a flood task force to examine the issues and make a recommendation for moving forward.  As a result, the City contracted a flood study to help identify structural and non-structural enhancements to the City’s flood response and defense systems.  This site is dedicated to keeping the community informed as we move through this process.

Wave one of public engagement is underway, and we need your input.

Current News

Since the Summer of 2020, staff and the consultant have been hard at work evaluating current flood measures and updating elevation data. As part of the holistic approach being used for the study, public input is a critical component for developing options and direction for Davenport’s future flood response.  Stakeholder conversations have started, and public input is needed. 

We are looking forward to hearing the community's thoughts.  Help us
 strengthen future flood response and Davenport’s riverfront experiences by providing input. Whether individuals share 50 comments or one, community feedback is valuable to us. All input is anonymous. 

Our one-on-one opportunities to provide input have been cancelled due to COVID-19 precautions going into place at various locations. Watch for paper and other opportunities to provide input. Just remember, the survey works great on smart phones, too.

Flood Study Overview

Davenport has seven distinct and unique riverfront areas.  The study will examine and provide recommendations across all project areas. 

  • McClellan to Mound
  • Bridge to 4th
  • 4th to Gaines
  • Gaines to Marquette
  • Marquette to Division
  • Division to Concord
  • Blackhawk and Walnut Creek

The scope of the study will incorporate information from existing plans and studies and include public input to develop an overall vision and objective for Davenport’s riverfront and flood response. Recommendations will incorporate these considerations.

  • Maintain land use viability in the areas within and adjacent to the floodplain.
  • Maintain transportation on River Dr between Davenport’s eastern city limits to 3rd and 4th streets.
  • Maintain traffic on 2nd Street between Iowa and Division.
  • Options for both structural and non-structural flood defense systems and techniques considering future climate impacts, including but not limited to flood proofing buildings, property buy-out, flood gates and pump stations, lift stations, and alternative drainage and overflow storage. All options will consider interior drainage requirements, on-going operational costs and any other identified concerns.
  • Review of current flood response plan for operational efficiencies and overall effectiveness.
  • Public input.
  • Feasibility.
  • Downstream impacts.

As a city positioned along the banks of the Mississippi River, flooding is a reality. Climate trends and operational requirements need to be considered to ensure Davenport remains resilient and continues to emerge from hardship with more strength, courage, and knowledge to keep us prepared for the future.

Increasing our resilience and operational agility means data. Lots of it. Find some of the data being evaluated as part of the study at the links below.  We hope these resources provide the community with some background and context as we move through the study and recommendation process.

Expect the list of resources to grow as the study progresses.
