Arroyo Valle

The Alviso Adobe Community Park is a 7-acre (2.8 ha) park in the city of Pleasanton, California, United States. It is built around an adobe house constructed in 1854 by Francisco Alviso on the Rancho Santa Rita Mexican Land Grant. The Alviso Adobe is a rare surviving example of an early American adobe that was continuously in use until 1969. The building is registered as California Historical Landmark #510 in 1954, but most of the historical marker was later found to be erroneous.Construction of the park was initially planned to begin in 2000, but the city could not secure funding until 2007, when the $4.4 million project was finally begun. The park opened to the public with a grand-opening ceremony on October 25, 2008. Besides the adobe, which is furnished as it would have been in the 1920s, the park contains a replica of an old dairy and interpretive displays of Ohlone culture.

Tulare Lake was a large, shallow lake in eastern Amador Valley, surrounded by Willow Marsh (also known as the Lagoon). Tule rushes and willow trees once lined the marshes and sloughs of its shores. Drainage alterations starting in the 19th century have since reduced the marsh to the Arroyo de la Laguna, and the city of Pleasanton has since expanded across what was once marshland. Such rapid developments have led to tricky seasonal flow variations in Niles Canyon.The lake was fed by Arroyos Mocho, Valle, and Las Positas (when rainfall was substantial enough for them to reach the lagoon), as well as by Tassajara Creek and other Amador Valley creeks. Its seasonal outlet was the Arroyo de la Laguna. Tulare Lake was densely inhabited by groups of the Ohlone people prior to the 19th century.

The Bernal Subbasin is an aquifer located in the southwestern corner of Livermore Valley Groundwater Basin, Alameda County, California, United States. All of the groundwater in Livermore Valley moves toward the Bernal Subbasin, which is bounded on the east by Pleasanton Fault, on the north by the Park Fault, and on the west by the Calaveras Fault.(Earth Metrics, 1989) All the streams draining the Livermore Valley merge above the Bernal formation and exit this subbasin and Livermore Amador Valley via the Arroyo de la Laguna. Groundwater occurs throughout the valley floor portion of the Bernal Subbasin under conditions ranging from unconfined to confined. There is no inflow of groundwater across the Pleasanton Fault south of the City of Pleasanton, because any movement of groundwater in the southern section is essentially parallel to the fault.(Bonnie, 2000) Groundwater in the Bernal Subbasin typically occurs at an approximate depths of 12 to 30 feet (3.7 to 9.1 meters) below ground surface and flows from east to west.

Alameda County ( AL-ə-MEE-də) is a county located in the U.S. state of California. As of the 2020 census, the population was 1,682,353, making it the 7th-most populous county in the state and 21st most populous nationally. The county seat is Oakland. Alameda County is in the San Francisco Bay Area, occupying much of the East Bay region. The Spanish word alameda means either "a grove of poplars...or a tree lined street". The name was originally used to describe the Arroyo de la Alameda. The willow and sycamore trees along the banks of the river reminded the early Spanish explorers of a road lined with trees. Although a strict translation to English might be "Poplar Grove Creek", the name of the principal stream that flows through the county is now simply "Alameda Creek". Alameda County is part of the San Francisco–Oakland–Berkeley, CA Metropolitan Statistical Area, and the San Jose–San Francisco–Oakland, CA Combined Statistical Area.
