Source: USDA NRCS soil survey (SSURGO), survey area IL179, version Aug 2026, read through NRCS Soil Data Access.

The parcel's main soil map unit covers about 25% of its outline: Osco silt loam, 2 to 5 percent slopes. Its main component is Osco (90% of the unit).

The ratings are NRCS's own map-unit interpretations (dominant condition): ENG - Septic Tank Absorption Fields, ENG - Dwellings W/O Basements and ENG - Dwellings With Basements. The limits listed are the features NRCS names for the main component. Shrink-swell is that component's linear extensibility, depth-weighted from 25 to 100 cm, the layer NRCS's homesite rule reads; NRCS classes: low under 3%, moderate 3 to 6%, high 6 to 9%, very high 9% or more.

A screening, not a perc test or a soil boring: soils vary inside a map unit (survey scale about 1:12,000 to 1:24,000), and fill or grading may have changed the lot.

This tracks home values, not land values. Land buyers read it as a sign of demand nearby: where homes gain value, builders and buyers follow. A vacant lot can move differently.

How: the change in FHFA's annual five-digit ZIP code index from 2020 and 2024 to 2025, rounded. The index follows repeat sales and refinance appraisals of the same single-family homes with Fannie Mae or Freddie Mac mortgages. It is in today's dollars, not adjusted for inflation, and FHFA calls these local indexes developmental. Where FHFA's sample is too small it publishes no figure, and none prints here.

Ratings come from FEMA's National Risk Index (v1.20, planning-level) and the public federal and state maps named on each row, not a private climate model. FEMA rates each census tract from expected annual losses, community resilience and social vulnerability, for planning; it is not an assessment of this parcel.

Insured buildings near this parcel, not the parcel itself. FEMA counts claims on buildings with NFIP flood insurance, so land that never had an insured building has no claims to count. The count is the parcel's census block group when it has 10 or more, else its tract's; a count under 10 prints as "Fewer than 10". Source: OpenFEMA NFIP Redacted Claims v3.

Each federal declaration whose designated areas include the county, declared from January 2000 on, counted once by its FEMA disaster number. An emergency declaration and a major-disaster declaration for the same storm are two declarations, as FEMA numbers them. Declarations for tribal lands alone are not counted. The date shown is when the most recent incident began. Types are FEMA's incident types: an evacuation emergency for a storm elsewhere (Hurricane Katrina, 2005) is listed as that, not as a storm that struck the county. By kind: 5 major disasters and 3 emergencies.

Counted from USGS Annual NLCD land cover (USGS Annual NLCD Collection 1.2, 30 m maps made from Landsat imagery, 2015, 2020 and 2025; public domain, DOI 10.5066/P94UXNTS). A 30 m square counts when it was forest, shrub, grassland, pasture, cropland or wetland in the start year and developed in 2025: NLCD's developed classes, from lawns, parks and roads to dense buildings. The squares are summed over the land within about a mile of this parcel's center on a 240 m grid, so the figures are rounded. "Most of the county" compares the same one-mile figure across the county's land. A satellite land-cover map misses some changes and mislabels a few, so read it as a guide to how fast the area is building out, not a survey. As of 2025 land cover.

± is the Census 90% margin of error; a figure comes from the larger census tract when the block group's sample is too small.
