Broderick (formerly, Washington) is a former town in Yolo County, California, United States, now forming part of the City of West Sacramento.

In October of that year she established the boundaries of her property and created a town plat of 41 blocks which she named Washington.

She sold several lots during the next few years, but Washington's plat was not officially recorded and the town was called by other names including "Margeretta" and "West Sacramento".

However, residents disliked their choice because Cacheville was so isolated and small, and moved the county seat back to Washington.

Unfortunately the weather proved disastrous in the winter of 1861–62, and in 1862 the voters held a special election to vote a permanent county seat.

In addition to that, a new junction was completed in Davisville (now Davis) that headed towards Woodland, diverting rail traffic from Washington.

[6] The largest employer in Broderick is the California State Teachers Retirement System, which built its headquarters on the waterfront.

The Ziggurat building, originally built as the corporate headquarters for The Money Store and now home to the State Department of General Services, sits at the edge of the area.
