Alameda County

Alameda County stretches from Santa Clara County North to Oakland along the East side of the San Francisco Bay, and to Livermore going East. Along with neighboring Contra Costa County to the North East it makes up what is referred to as the East Bay.

Oakland is by far the largest city. It includes the Port of Oakland which is a major Container Shipping Port.

It is a very diverse region in just about every way you could imagine. From Union City South it would be hard to see much difference from Santa Clara County. You will find similar housing and the same kind of hi tech employers.

A significant number of people commute down to Silicon Valley. This trip has recently been improved by a regular passenger train service from the South East of the County into the heart of Silicon Valley. Major improvements to Highways 880 and 680 have also helped greatly with road travel.

For those commuting across the San Francisco Bay there is little option but the Freeway and 3 bridges. However, if working in Oakland or San Francisco City the BART (Bay Area Rapid Transit) is a viable option from as far South as Fremont, and as far East as Livermore and Pleasanton.

From Union City North you are into the older parts of the County which are generally oriented more toward older style manufacturing employment.

My personal experience and knowledge is restricted to the South County Cities of Fremont, Newark, Union City, Hayward, Pleasanton, San Ramon, Dublin, and Livermore which can reasonably be thought of as extensions to Silicon Valley.
