Frequently asked questions

What are the soils like in Peoria County, Illinois?
The USDA soil survey maps 249,298 acres of Peoria County, Illinois as well drained and 126,495 acres as poorly drained. Drainage class and hydrologic soil group are the two properties that most often decide whether a rural lot can take a septic system and a driveway.
Is this soil map free to use?
Yes. This map is free to view. A free Land Owl account unlocks the other data layers, parcel boundaries and ownership records.
Where does this data come from?
Land Owl maps soils from the USDA Natural Resources Conservation Service SSURGO soil survey. SSURGO describes soil MAP UNITS at survey scale — it is a screening tool for shortlisting land, not a substitute for a site-specific soil evaluation or a septic percolation test, both of which your health department will want before it permits a system.
Can I use this soil map to tell whether land will perc?
It is the right place to start and the wrong place to finish. Drainage class and hydrologic soil group tell you which parcels are worth a site visit, but a health department permits a septic system on a percolation test dug on the actual lot, not on the survey.
