Community Survey Schedule

The Illinois Department of Natural Resources, Office of Water Resources (IDNR/OWR) is partnering with the Prairie Research Institute to examine flood risk throughout Rock Island County, Peoria County, and the City of Ottawa.

A professionally licensed survey crew will be in these areas between June through October. 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. Approximately 3,200 homes will be surveyed in Rock Island County, 1,500 in Peoria County, and 120 in Ottawa. No disruption to the property is anticipated.
