Gold Coast Historic District, Historic district in Richland, United States.

The Gold Coast Historic District is a residential area in Richland, Washington, with houses built in 1948–49. The district contains 118 contributing and 45 noncontributing properties. The photograph shows detached houses with red-pitched roofs and pale siding, including a two-storey house with white horizontal siding, a brick chimney, a gabled entry porch with a short white railing, and windows with dark shutters, next to a single-storey house with an attached carport open on the front.

Richland was built from 1943 under a master plan after displacing the existing village, reaching 25,000 residents by 1945. The government owned all land and housing, assigning units by family size and need through waiting lists. Cold War plutonium expansion at Hanford created demand for new neighborhoods in 1948–49, and the Gold Coast Historic District is one of them.

The name "Gold Coast" was already in use by 1952 for this neighbourhood of upper-income families near the Columbia River. The houses were government property, assigned by waiting list, and residents paid only nominal rent. The street layout and the letter-coded floor plans of the alphabet houses remain visible today.

The district lies near the Columbia River in Richland, Washington, and its 1948–49 houses face public streets, so the architecture can be seen from the sidewalk without entering private property. The photograph shows detached houses with red-pitched roofs, pale siding, brick chimneys and an attached carport, set behind green lawns along a paved street.

The district holds 118 contributing and 45 noncontributing properties, listed on the National Register in 2005. Its nomination grew out of a local inventory of 5,000 alphabet houses compiled in the early 2000s. The nickname "Gold Coast" was already in use by 1952.
