List of ghost towns in California

Drawbridge (formerly Saline City) is a ghost town with an abandoned railroad station located at the southern end of the San Francisco Bay, next to Station Island, now a part of the city of Fremont, California, United States. It is located on the Union Pacific Railroad 6 miles (10 km) south of downtown Fremont, at an elevation of 7 feet (2 m). Formerly used as a hunting village, it has been a ghost town since 1979 and is slowly sinking into the marshlands. It is now part of the Don Edwards San Francisco Bay Wildlife Refuge and is illegal to visit.

The Newby Island Landfill (NISL) is one of the largest active landfills on the shores of the San Francisco Bay. It is located in Santa Clara County, California in the United States. The site is located within the city limits of San Jose, California at the western terminus of Dixon Landing Road. The address is 1601 Dixon Landing Road, Milpitas. Although the address and public street access to the site are both in the City of Milpitas, the landfill property is entirely within the City of San Jose. Newby Island Landfill has a length of 5.07 km (3.15 mi). It is located West of the City of Milpitas near Dixon Landing Road and Interstate 880. It is the terminus for waste for all of San Jose (62%), Santa Clara (14%), Milpitas (10%), Cupertino (5%), Los Altos (2%) and other cities (7%). The 342-acre (138.4 ha) pile is currently permitted to operate until 2041 and may extend up to 245 feet. The landfill is an island surrounded by a levee which keeps its runoff from directly entering the bay, and the water that drains from it is treated in the landfill's own treatment plant. Electricity for the landfill is generated by burning the methane collected from the decomposition of the waste. Dried sewage sludge from the nearby San José–Santa Clara Regional Wastewater Facility is the material used as cover, mixed in with the trash, blending San Jose's waste streams. It is operated by Republic Services (Republic), which, along with Waste Management Incorporated, transports and disposes of most of the household trash in the United States.Materials that pass through the gate of NISL include waste that is disposed in the landfill; clean soil that is used for cover and for temporary roadways; construction and demolition (C&D) debris that is sorted, recycled, and processed for re-use both on-site and elsewhere; and materials that are used for alternative daily cover (ADC), which include but are not limited to biosolids, processed C&D debris, contaminated soil, green waste, and organic material from the on-site composting operations. In addition to C&D waste, bulky recyclables including appliances, tires, carpet, and cardboard are sent to NISL and either are recycled or diverted for beneficial use. Incoming organics received at the landfill are processed (i.e.,ground) and utilized as mulch for erosion control on-site and alternative daily cover or are sent off-site to be used as biofuel, for erosion control, or as a soil additive.The entire site is now called the Newby Island Resource Recovery Park. The site includes both the Newby Island Landfill and the Recyclery.

Ogilvie Island is a patch of mud in San Francisco Bay. It within the limits of the city of San Jose, in Santa Clara County, California, and named for county planner Arthur Ogilvie. Its coordinates are 37°27′55″N 122°00′37″W, and the United States Geological Survey gave its elevation as 0 ft (0 m) in 2012. It appears on a 2012 USGS map of the area.

The Fremont Dragstrip was a racing venue for dragster automobiles that was located in Fremont, California in the San Francisco Bay Area, operating from 1959 until the end of 1988.

The Guadalupe River (Spanish: Río Guadalupe; Muwekma Ohlone:Thámien Rúmmey) mainstem is an urban, northward flowing 14 miles (23 km) river in California whose much longer headwater creeks originate in the Santa Cruz Mountains. The river mainstem now begins on the Santa Clara Valley floor when Los Alamitos Creek exits Lake Almaden and joins Guadalupe Creek just downstream of Coleman Road in San Jose, California. From here it flows north through San Jose, where it receives Los Gatos Creek, a major tributary. The Guadalupe River serves as the eastern boundary of the City of Santa Clara and the western boundary of Alviso, and after coursing through San José, it empties into south San Francisco Bay at the Alviso Slough. The Guadalupe River is the southernmost major U.S. river with a Chinook salmon run (see Habitat and Wildlife section below). Much of the river is surrounded by parks. The river's Los Alamitos and Guadalupe Creek tributaries are, in turn, fed by smaller streams flowing from Almaden Quicksilver County Park, home to former mercury mines dating back to when the area was governed by Mexico. The Guadalupe watershed carries precipitation from the slopes of Loma Prieta and Mount Umunhum, the two major peaks of the Sierra Azul, the historical Spanish name ("Blue Mountains") for that half of the Santa Cruz Mountains south of California Highway 17. Two of the Guadalupe River's major tributaries, Los Gatos Creek and Guadalupe Creek have their sources in the Sierra Azul Open Space Preserve on the western and eastern flanks of the Sierra Azul.

Pacific Commons is a master-planned, mixed-use development consisting of 840 acres in Fremont, California currently in development by Catellus Development Corporation. It sits on part of the site of what was once the Fremont Dragstrip/Baylands Raceway Park and the Sky Sailing Airport, a glider field. Given Fremont's location at the Northern tip of Silicon Valley, Catellus originally planned the development to house primarily high-tech research and development operations with a moderate amount of retail and restaurant space, a convention center, and a hotel. Until the dot-com bubble, Cisco Systems had planned to relocate its headquarters to Pacific Commons and consolidate substantially all of its San Francisco Bay Area operations to a large campus in Pacific Commons, which would have consisted of several high-rise office buildings. With the downturn in the technology industry, however, Cisco put its plans on hold. While it is unclear whether Cisco will ultimately relocate its headquarters to Fremont, in 2011 Cisco purchased 149 acres of vacant land in Fremont, most of it from Catellus, fueling speculation that, at some point, it will move forward with its headquarters move to Pacific Commons. To mitigate environmental impacts caused by the massive of the project, Catellus donated hundreds of acres of land along the southern and western boundaries of Pacific Commons to the Don Edwards San Francisco Bay National Wildlife Refuge. Further environmental mitigation involved building a causeway as a portion of Cushing Parkway over the wetlands preserve from Pacific Commons southward to Fremont Boulevard and Interstate 880 near the Fremont Marriott Hotel. Today, Pacific Commons contains more than one million square feet of research and development and industrial space, including a half-million square-foot distribution center for Office Depot. More than one hundred acres of land slated for research and development uses remains undeveloped.

Alviso is a district of San Jose, California, located in North San Jose on the southern shores of San Francisco Bay. Originally an independent town, founded in 1852, today Alviso is San Jose's only waterfront district, primarily residential in nature, with several Silicon Valley tech companies and recreation-oriented businesses. Alviso is named after 19th-century Californio ranchero Ignacio Alviso, who owned the area as part of his Rancho Rincón de Los Esteros. The Guadalupe River separates Alviso from Santa Clara and Sunnyvale to the west, while Coyote Creek separates Alviso from Milpitas to the east. Alviso is the lowest point in the San Francisco Bay Area at 13 feet (4.0 m) below sea level.

The San José–Santa Clara Regional Wastewater Facility (abbreviated RWF; officially the San Jose/Santa Clara Water Pollution Control Plant) is a wastewater treatment plant located in the Alviso neighborhood of San Jose, California.

It serves 1.5 million residents and over 17,000 business facilities in eight cities. The 2,600-acre (1,100 ha) site is operated by the San Jose Environmental Services Department and jointly owned by the cities of San Jose and Santa Clara. It began operations in 1956 to address severe water pollution issues and played a key role in San Jose's aggressive annexation program during the 1950s and 1960s.
