This is a project done in partnership with and at the request of the Illinois Department of Natural Resources, Office of Water Resources.

Over the course of the project surveyors will be sent to your community and onto and around your property to survey and document your property’s potential flood risk. Surveyors will be clearly marked and will carry ID, they will bring surveying equipment with them. They will also be using photography equipment around your property to assist with the creation of a structural flood risk inventory. There will be no impacts to your utility services.

Surveyors will be acquiring first floor (front door sill), lowest entry (window vent or crawl space) and typical ground elevations on your property. This specific information will help estimate the potential flood threat and damages to your home or business.

A Flood Risk Assessment aims to create information in order to better understand and estimate the real impacts of different flooding events. This project will map and analyze flood damage risk on a structure by structure basis. Structure specific survey information will help estimate the amount of risk an area could face in the event of a flood. This Risk Assessment will send surveyors in and around your community to map and document properties in the floodplain, and their potential risk for flood damages.

Check the “Schedule” portion of this page for regular updates on when to expect surveyors in your community.

If you have any questions about the Flood Risk Assessment project, including timeline, logistics, or impacts on you and your community please call (309) 794-5729.

The analyses of potential flood losses is a function of the type of structure. The photo helps insure proper interpretation of the assessor’s data and the surveyed elevations.

The impacts of flooding vary greatly from extreme events that cause severe damage across communities to smaller flooding events that cause nuisance flooding more frequently. Estimating the depth of inundation for different scenarios can help community planners and homeowners determine the best solution for flooding issues.

At this time the information will only be shared with state and local officials, primarily for mitigation planning purposes. After the study is complete you can request the information from your community floodplain manager.

The data collected is not to the standards required for use on an Elevation Certificate, however the information can be used as a screening process for properties where it would be appropriate to obtain an EC.

No, the information developed will provide local and state officials with information on risk associated with flooding.

Schedule

Locations are currently being assessed and will continue to be assessed from November 2018 to March 2019.

Upper Mississippi River - Illinois Flood Risk Assessment

Anyone who has experienced the devastating effects of a flood can tell you that the difference between 2 inches of water and 2 feet of water can mean a long day of cleaning, or being forced to leave your home. Just knowing where flooding can occur is not enough.

Structures-based Assessments

In partnership with the state of Illinois, the U.S. Army Corps of Engineers is conducting assessments which will provide accurate and accessible information to help communities become safer from floods.

Structures most at risk for flooding will be surveyed. Teams of two surveyors will spend about 20 minutes on each property, measuring the elevation of the first floor and the lowest entry point for water flooding into a home.

The goal of this project is to develop a statewide database with building-specific flood hazard and flood risk information for structures. This information can then be used by community officials to help make informed decisions and aid in mitigation planning. The information may also be useful for strategically prioritizing building acquisitions and identifying appropriate mitigation options.

Assessment Locations

Areas marked with red boxes on the map shown here will be assessed by the Corps of Engineers in the coming months.
