Its largely vernacular buildings, including many I-houses built by the Walton family, record an unbroken line of development from the 1840s to the 1920s. Mills, a pork-packing operation and local commerce shaped the street.","narrative":"Main Street in Spring Valley, Greene County, Ohio, is a village streetscape of modest frame houses, shops, a warehouse and a township hall. The village was platted in 1844 along the Cincinnati-Xenia Pike, and the Little Miami Railroad arrived at about the same time. A small commercial district formed at the railroad crossing on West Main, while larger houses rose along East Main. Many early buildings are I-houses built in the 1840s and 1850s by the Walton family, Quakers from Virginia. Later brick commercial buildings include the 1874 Pork House and the three-story Township Hall of 1888. Farming, milling and pork packing supported the village, and the Barrett family later became prominent. Rerouting of Route 42 in 1954 left the street largely bypassed, which helped preserve its appearance. The district contains 66 contributing resources and shows a continuous record of growth from the 1840s to the 1920s.","period_of_significance":"1840s-1920s (about 75 years of growth; exact date range not shown in the available text)","architect_builder":"Edward Walton and Moses Walton (builders of several houses)","architectural_style":"Mid-19th Century: Other; I-House; Greek Revival; Queen Anne","criteria":[],"status_note":"Most buildings remain in residential, commercial, governmental and industrial use; two former churches have been converted to residences and some early structures have been lost or are endangered.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:14.563661-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/89000431.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71988732","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/greene-county/main-street-historic-district-89000431/"}
