Yolo County is included in the Greater Sacramento metropolitan area and is located in the Sacramento Valley.

The majority of Yolo County remains a relatively rural agricultural region.

Etymology

In the original act of 1850 the name was spelled "Yola." Yolo is a Patwin Native American name variously believed to be a corruption of a tribal name Yo-loy meaning "a place abounding in rushes", the village of Yodoi, believed to be in the vicinity of Knights Landing, California, or the name of the chief of said village, Yodo.[7][8]

History

Yolo County was one of the original counties of California, created in 1850 at the time of statehood.

Government

The county is governed by a board of five district supervisors as well as the governments of its four incorporated cities: Davis, West Sacramento, Winters, and Woodland.

Major highways

County roads

Addressing in Yolo County is based on a system of numbered county roads. The numbering system works in the following way:

  1. North–South roads have numbers from 41 to 117 and increase from west to east.
  2. East–West roads have numbers from 1 to 38A, and then from 151 to 161, and increase from north to south.

Each integer road number is generally one mile (1.6 km) apart, with letters occasionally designating roads less than one mile (1.6 km) apart. County roads entering urban areas generally become named roads once they cross a city boundary. Some examples include County Road 101 in Woodland being renamed Pioneer Ave. and County Road 102 (also known as County Route E8) in Davis being named Pole Line Road.
