Davenport Iowa Flood Response and Recovery Planning – Silver Jackets Interagency Project

Published March 25, 2020

Location
Davenport, Iowa

Description
This project will evaluate the city of Davenport’s current flood response plan as part of a city-led effort. This effort includes local businesses as well state and federal agencies. Project will include planning and risk assessment evaluations to help inform impacts of a suite of potential non-structural measures. This will include modeling floodplain impacts as well as basic economic evaluations (structure evaluations). Information will be used to update the city’s flood response plan and Master Plan for the river corridor.

Background 
Record Mississippi River flooding in Davenport, Iowa, in 2019, resulted in a breach of a HESCO flood barrier. Failure of this barrier resulted in millions of dollars of damage and displacement of numerous people from their homes and businesses. 

The proposed effort will reduce life safety risks by identifying where non-structural measures may be utilized to assure the city can withstand record flooding. Effort will reduce life safety risks by updating action levels for certain residents or businesses without protection to evacuate their homes during periods of heavy flooding. This effort will reduce increases in flood risk by taking action on current structures combined with smart floodplain management recommendations that identify the right types of infrastructure for future development. This effort may also help Davenport achieve a higher Community Rating System rating.  

Status
The project was funded and initiated in fiscal year 2020 as a Silver Jacket inter-agency project. The focus is on working with the city and other Silver Jacket partners to evaluate and provide non-structural recommendations to support the city of Davenport Flood Response Plan.
