When we launched our Flood Guidance feature in January, it excluded advice for properties in DuPage and Will Counties. We didn’t want to, because that’s where 929,000 and 689,000 people live, respectively, but the flood maps weren’t finalized for those counties.

Flood maps in the two counties are still not finalized, actually, but we didn’t want to wait any longer. The flood maps were completed last summer and entered a “preliminary” status.
We’ve gone ahead and added the Flood Insurance Rate Maps (FIRM) for every property and address lookup in DuPage and Will Counties, so there’s no gap in our suburban expansion.
Flood Guidance is viewable to our users with a Cityscape Permits membership (ideal for contractors and homebuyers) and Cityscape Pro membership (ideal for developers and other real estate professionals).
You can view the status of other flood maps in Illinois on a University of Illinois website aptly named Illinois Flood Maps.
