Collection of maps surveyed for the
Los Angeles County Assessor’s Office between 1860 and 1897. The maps primarily focus
on excavations, improvements, and expansions of roads throughout Los Angeles, San
Bernardino, and Orange Counties. Most of the maps show boundary lines of the various
Ranchos existent throughout these counties, and many also include houses, railroads,
telegraph lines, and elements of the natural landscape such as canyons and rivers.
The Los Angeles County Office of the Assessor, which has operated since 1850, locates
taxable property in Los Angeles County, identifies land owners, and establishes a
taxable value for all property. Twelve different individuals held the position of
Assessor from 1860-1897, beginning with W.W. Maxy from 1859-1861 and ending with
Theodore Summerland from 1894-1898.
