It includes buildings dating from 1852 to 1898 and about forty-five pre-1900 private homes.","why_significant":"The nomination argues that the whole town shows classic, unspoiled Gold Rush architecture. Dutch Flat was a major hydraulic mining center from 1854 to 1882 and a key point on the freight route linking Nevada's silver mines to California. Theodore Judah determined the railroad route through the Sierra here and began forming the Central Pacific Railroad with Dr. D. W. Strong.","narrative":"Dutch Flat, in Placer County, California, is preserved as a historic district of about 48 acres around Main and Stockton Streets. Founded in 1851, the town became a center of hydraulic mining between 1854 and 1882. Its surviving buildings include the 1852 hotel, an 1854 general store built of locally quarried tufa, the 1856 Masonic hall, the 1858 Odd Fellows lodge, a Methodist-Episcopal church finished in 1861, and an 1898 schoolhouse that replaced an earlier one and now serves as a community center. A single adobe building is the last remnant of the original Chinatown, once home to about 2,000 residents. Forty-five private homes built before 1900 remain on their original sites, nearly unaltered. The district was recognized for its largely unspoiled Gold Rush architecture and for its role in transportation history: the Dutch Flat-Donner Lake freight route, the Pony Express route, and Theodore Judah's work on the Central Pacific Railroad.","period_of_significance":"19th Century","architect_builder":null,"architectural_style":"Gold Rush architecture","criteria":[],"status_note":"Condition is listed as good and unaltered, on original sites.
