The county seat of San Mateo County, it is the home of several technology companies such as Oracle, Evernote, Wealthfront, and Electronic Arts. At the 2010 census, the city had a population of 76,815. The Port of Redwood City is the only deepwater port on San Francisco Bay south of San Francisco. Redwood City is the location of the San Mateo County Jail, for both women and men. The Malibu Grand Prix long time landmark was recently demolished along with the city's only Mini Golf, Go-Kart, Video Game Arcade, and Batting Cages. Malibu Grand Prix's previous location is currently the construction site of a new additional Jail and Inmate housing facility. The city has a motto "Climate Best By Government Test" which is a reference to it being one of the top German scouted scientific climates and the city was one of the locations mapped by them during their testing and data collection. The Hetch Hetchy water pipeline runs through Redwood City and supplies a vast majority of the surrounding area with low grain(+/-3grains) rated water.
