Thomas 1997  p.752  D-3.
Home of the Patterson family on their ranch. Now restored in Ardenwood Regional Preserve and used for various activities recreating Victorian life. George Washington Patterson came to California in the gold rush. With his family, he settled in the area that is now northwestern Fremont in 1854, draining and clearing wetlands and shorelands. The house was built in 1856 as the centerpiece of what became a 3,000-acre farm called Ardenwood (presumably a Shakespearean reference). The house was expanded in 1880. The present Ardenwood Preserve includes only 205 acres of the ranch, which extended into the present Coyote Hills Regional Park. Most of the land was subdivided.

DeLorme Northern California  p.115  A-7.  Thomas 1997  p.815  BC-5.
Originates in the hills east of San Jose and flows generally westward through Alum Rock Park and Penitencia Creek County Park before being diverted into Coyote Creek where Berryessa Rd crosses it. This portion of the creek is known as Upper Penitencia Creek. Much of the creek's course through San Jose has been buried in storm drains. Lower Penitencia Creek emerges near E Capitol Ave at the Milpitas border and flows briefly westward then northward and into Coyote Creek just south of the Alameda County border. Most of the course of Lower Penitencia Creek has been altered in storm channels. The name is said to come from an old adobe house near the creek that was used for confessions.

People's Park
Thomas Contra Costa  p.68  C-7 (unmarked).  Thomas 1997  p.629  J-2 (unmarked).
Most of the block in Berkeley bounded by Telegraph Ave, Dwight Way, Bowditch St, and Haste St (except for the businesses along Telegraph Ave).  In 1967, the University of California - Berkeley purchased this land for future use as playing fields and parking lots.  After the longtime residents moved out, most of the houses were rented to UC students, many becoming communal households.  During finals week in 1968, the renters were evicted and the houses were torn down.  There were charges that the University was acting primarily because many student activists lived in the block, an idea that seemed to be confirmed when UC left the lot vacant and unimproved for the next year.  UC claimed that the land was now slated for new student dormitories, but in the meantime it was being used as an unofficial dirt parking lot.  In April 1969, some people declared the lot to be a "People's Park" and began planting flowers and vegetables and creating public facilities there.  Various public planning meetings were held, and many people from students to older residents participated in creating the park.  The University responded early on May 15 by erecting a chainlink fence around the lot and destroying the park "improvements."  A rally at Sproul Plaza on the UC campus ended with a crowd storming down Telegraph Ave to the park; police from several local jurisdictions fired teargas and buckshot into the crowd.  Dozens were injured and one man watching from a rooftop was killed by police buckshot (they claimed that he had thrown a brick at them).  Governor Ronald Reagan banned all public assemblies in Berkeley, and on May 17 the California National Guard was sent into Berkeley to maintain order, establishing their headquarters behind the chainlink fence on People's Park.  On May 20, a National Guard helicopter dropped a chemical agent on a demonstration in Sproul Plaza.  Eventually, the University and the city of Berkeley reached an agreement to allow the park to exist.  The struggle has continued off and on over the years, with sporadic UC attempts to develop the site generally defeated, although volleyball courts have been built on the site, and various "people's" improvements such as a free food distribution center have been ejected.

Created in November 1963 by a vote of the residents of Alameda, Albany, Berkeley, Emeryville, Oakland, and Piedmont, officially coming into existence in July 1964. The name was chosen because the cities of the district are all located on the 1820 land grant of Luis Maria Peralta. It took over the Laney and Merritt campuses of the former Oakland City College. The new College of Alameda campus was opened in June 1970. Vista College has had a troubled existence but is currently operating in Berkeley.

Port of Oakland
In 1852 Oakland's first mayor, Horace W. Carpentier, was given title to all of the waterfront property in return for building a wharf at the foot of Broadway and a public school. Carpentier got the land conveyed to a new Oakland Waterfront Company, which gave control of it to Central Pacific Railroad to entice the railroad to locate its western terminus in Oakland. Carpentier ended up with a seat on the board of the railroad. Southern Pacific later took over the holdings of Central Pacific. These highly suspicious dealings were the subject of litigation for decades. Finally, in 1909, the railroad gave the land back to the city in return for a 50-year lease. In hopes of preventing future scandals, a semi-independent body called the Port of Oakland was set up to manage and develop the waterfront property.
