It includes a four-story grain elevator, three warehouses, an office building and a feed store, built between about 1906 and 1935.","why_significant":"The complex is significant for commerce as a representative example of the prominent role of grain processing and storage in the local economy. It has operated since 1906, first as a grain elevator and later as a feed mill. It is the only historic feed mill still operating in McKinney.","narrative":"Along the railroad tracks just east of downtown McKinney, this industrial complex at 400 E. Louisiana has handled grain since 1906. It covers about three acres and includes a four-story frame grain elevator clad in sheet metal, three frame warehouses with corrugated-metal siding, a brick office building with a hip roof, and a gable-roofed frame feed store at the northeast corner. Construction dates run from about 1906 to 1935, and every building is described as virtually unaltered. The business was known as the Hill-Webb Elevator Co. and the McKinney Elevator Co. It began as a grain elevator and by the late 1930s had been converted into a feed mill. Its listing rests on commerce: it illustrates how agricultural production and processing shaped the local economy, and it is the only historic feed mill still operating in McKinney.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":["A"],"status_note":"Condition listed as fair; all structures are described as virtually unaltered, retaining historic integrity, and the site is still used as a feed mill.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:21.751577-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/17/9686/40968617/content/electronic-records/rg-079/NPS_TX/87001716.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40968617","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q110000103"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/collin-county/hill-webb-grain-elevator-87001716/"}
