Understand
Concord is located 29 miles east of San Francisco, meaning that the commute through the Caldecott Tunnel and across the Bay Bridge can be done in approximately thirty minutes when traffic is light, and in less than a week when traffic is heavy. The total area of the city is 31.13 square miles, and with over 120,000 residents Concord is the largest city in Contra Costa County.
Concord is perhaps best known for the De La Salle High School football team, which between 1992 and 2004 established a national record winning streak of 151 games, shattering the previous record of 72 games. During this time the team was named ESPN national champion in 1994 and USA Today national champion in 1998, 2000, 2001, 2002, and 2003. Concord's other claim to fame is that it is the birth place of actor Tom Hanks, who is well known for numerous critically-acclaimed movies including Turner & Hooch, Bachelor Party and Joe Versus the Volcano. Jazz artist Dave Brubeck of "Take Five" fame is also from Concord and one of Concord's several parks is named in his honor.
There is a campus of Cal State East Bay (http://www.csueastbay.edu) in Concord.
