The Illinois Department of Natural Resources, Office of Water Resources (IDNR/OWR) is partnering with the Illinois State Water Survey, Rock Island District US Army Corps of Engineers, and the City of Rock Island to examine flood risk in the Mississippi River watershed.  

A IDNR/OWR survey crew will be in the flood risk areas beginning in mid-January and continuing through the spring.  This work will require the survey crew to briefly come onto individual properties to collect necessary elevation information.  The surveyors will be acquiring first floor (front door sill) and lowest entry (window well or crawl space vent) elevations to determine potential flood threat to homes or businesses and many neighboring structures in the Mississippi River watershed.  No disruption to property is anticipated.  

This work is being performed under the authority granted to the Department in 615 ILCS 15/7.
