The Sanborn run, measured: no Granger, and the county's fire-insurance geography

Tested negative for Granger. The Library of Congress Sanborn online checklist and the Indiana Sanborn inventory at Indiana University (the Indiana Spatial Data Portal set: 11,517 images, 305 Indiana locations, Sanborn's Indiana production running 1883–1966) were checked for Granger in November 2026. Granger is not among the 305 locations. No Sanborn surveyor ever sheeted this ground, for the same reason no bird's-eye was drawn: Sanborn sold building-by-building fire-risk sheets (scale 1:600) to insurers, and insurers needed them where buildings stood close enough to burn together. The county's Sanborn geography is its two cities — South Bend and Mishawaka carry the county's runs inside the statewide 1883–1966 span, with the public-domain editions (to 1923, 87 per cent of the Indiana set) downloadable from IU and the later editions held under restriction — plus small-town sheets elsewhere in the county in the same inventory. The register's test span of 1885–1949 was not confirmed as the exact first-and-last for either city from an open title record in this section, and those exact years are left as a named gap rather than approximated. For this build the measured result is the boundary itself: every Granger structure of the Sanborn century — farmhouses, the Clay and Harris schoolhouses, the Granger depot ground — was insured, if at all, without a Sanborn sheet, and the fire-insurance map record of the CDP is a documented blank between the South Bend and Mishawaka runs.
