Why it's listed
Along River Road and Brown's Alley in Walnut Grove, a five-acre group of buildings marks the earliest commercial core of this Sacramento River Delta town. The site began as a boat landing established by John Sharpe in 1851. Alex Brown arrived in 1879 and went on to build or acquire most of the district's structures. They include a circa 1884 town hall, a 1916 brick Neoclassical bank with stone Corinthian columns, a brick general store built in 1915, and a Craftsman house for his son. Brown also subdivided Brown's Alley beginning in 1918, building rental cottages in Craftsman, Neoclassical and Colonial Revival styles for Anglo workers and farmers in a predominantly Asian community. The district contains 18 contributing buildings and 6 noncontributing ones. Its listing rests on Brown's role in the commercial development of the Delta and on its collection of the town's oldest buildings, which together convey an 1880s to 1920s river town.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
