Individuals will also have the ability to research comparable property for purposes related to property tax information.  Other search information includes flood zone areas, topography, wetlands, and aerials.

McHenry County was the first in Illinois, I believe the first in the nation, to map its soils. Now you can see them online.

“Athena was developed as an information tool by taking multiple systems and combining them into one geographical interphase. This new search viewer will be a new useful tool to property owners, real estate agencies, title searchers, County departments for analysis purposes, and individuals looking to relocate to McHenry County,” stated McHenry County GIS Director Nicole Gattuso.
