How to find out if your area is a tri-county or quad-countys site
Posted On July 24, 2021
The Tri-State region is a complex region of the United States that spans parts of California, Oregon, Nevada and Utah.
The region consists of seven states: California, New York, Arizona, Nevada, Texas, Colorado and Washington.
The Tri West region includes parts of Oregon, Utah and Washington State.
It is comprised of two main regions: the Central Valley, and the South West, a region which includes the Los Angeles Basin, San Francisco Bay and the Washington state border.
To get a sense of how each region is different, the site on the state website offers a list of tri-states regions that are available in both tri- and quad-states.
Tri-State Regions are usually divided into six different geographic areas, with the Tri West being the only region in which the area is subdivided into two separate areas.
However, there are no such boundaries.
According to the website, the Tri-States regions are:California, NewYork, Arizona , Nevada, Utah, Colorado, Washington and Tri West.
Each of the six regions have their own specific geographies, however, the locations of the areas within each region are different.
For example, in the Central West, the area in the San Francisco area is the San Mateo County area, while the area outside the San Jose area is known as the Santa Clara County area.
This can mean that when comparing tri- or quad (or tri-region) regions, you should be aware of which region you’re in.
In addition, some of the regions may be geographically similar to each other.
Take a look at the map below for a closer look at what’s going on within each of the Tri State regions.
