Useful Info for Contra Costa County

Contra Costa County is from the Spanish meaning "opposite coast" and is a suburban county located near the San Francisco bay area. Contra Costa County was formed between 1836 and 1846, when the state of California was a province under an independent Mexico. Originally consisting of 15 individual land grants, things changed for the area in 1846 with the Bear Flag Revolt. One of the original 27 counties when California was admitted as a state, it was originally supposed to be called Mt. Diablo County. The name was changed prior to its incorporation as a county.

The arrival of BART, modernizing Hwy. 24, and expanding the Caldecott Tunnel have all contributed to the vast changes Contra Costa County has undergone. Any County depends on the taxes paid for survival, and one of the largest components of taxes comes under real estate taxes assessed and paid. The housing bubble burst over the last decade has created many problems on programs run with county taxes. In addition to the problems from the housing decline, underfunded pensions for county employees has suffered from the deduction in tax collections. Hopefully these two problems can be solved if the economy improves.
