Dublin/Pleasanton station is a Bay Area Rapid Transit (BART) station on the border of Dublin and Pleasanton in California. It is the eastern terminus of the Blue Line. It is also a major bus terminal served by six providers. The station consists of an island platform located in the center median of the elevated Interstate 580. A fare lobby is located under the platform; a pedestrian and vehicle underpass connects the station to bus bays, parking lots, a parking garage, and surrounding development. The Iron Horse Regional Trail connects to both the north and south sides of the station.

South San Ramon Creek is a 9.3-mile-long (15.0 km) southward-flowing stream in Alameda County and southern Contra Costa County, in the East Bay region of northern California. The creek is a tributary to Arroyo de la Laguna, flowing in the western Livermore Valley through Dublin and Pleasanton.

Arroyo Mocho is a 34.7-mile-long (55.8 km) stream which originates in the far northeastern corner of Santa Clara County and flows northwesterly into eastern Alameda County, California. After traversing the cities of Livermore and Pleasanton it joins South San Ramon Creek to become Arroyo de la Laguna, which in turn flows to Alameda Creek and thence to San Francisco Bay.

Dougherty (also, Amador's, Amador Valley, and Dougherty Station) was an unincorporated community in Alameda County, California. It was associated with two separate areas near Dublin, the first at an elevation of 348 feet (106 m). James Witt Dougherty purchased the land in and around what is now Dublin, CA, in 1852. The land included a two-story adobe building that formerly belonged to Jose Maria Amador. A community grew up around the adobe and associated ranch, and was first called Amador's and Amador Valley after Jose Maria Amador the original owner of Rancho San Ramon (Amador). Dougherty built a hotel near the adobe and at the crossroads of two important local roads. One road went north–south and connected communities from Martinez south to Mission San Jose. The other road went east–west and connected the San Francisco Bay area with communities such as Livermore, Stockton and the California Central Valley. Dougherty obtained the post office contract in 1860 and used the name Dougherty Station. The post office name was shortened to Dougherty in 1896 and it closed in 1908.The second Dougherty was a platted area about two miles east of the original location. It was established by Charles Medley Dougherty, the son of James Witt Dougherty, and named after the family. It was designed to take advantage of an extension of the Southern Pacific Railroad connecting from San Ramon to Pleasanton in the early 1900s. Besides a railroad platform, there may never have been any homes or businesses constructed in the planned community. The area, Dougherty, continued to appear on some maps throughout the Twentieth century and may still be found on some online maps.

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.

Amador Valley is a valley in eastern Alameda County, California and is the location of the cities of Dublin and Pleasanton. Part of Tri-Valley, the valley is bounded by the foothills of the Diablo Range on the north and south, Pleasanton Ridge to the west, and Livermore Valley to the east. Watercourses draining into the Amador Valley include South San Ramon Creek, Tassajara Creek, Arroyo Mocho, Arroyo Valle, and Arroyo Las Positas, as well as runoff from Pleasanton Ridge. These waters drain south through Arroyo de la Laguna to Alameda Creek, ultimately ending up in San Francisco Bay.

Komandorski Village was a temporary low-rent housing development in Dublin, Alameda County, California. It was built to hold the overflow of military personnel and families from Camp Parks. It was sold by the United States government to a housing authority in 1954, and was required to be demolished in 1984. It was located 2 miles (3.2 km) northeast of central Dublin, at an elevation of 371 feet (113 m).

The Federal Correctional Institution, Dublin (FCI Dublin) is a low-security United States federal prison for female inmates in Dublin, California. The facility also has an adjacent satellite prison camp housing minimum-security female offenders. FCI Dublin is located 20 miles southeast of Oakland on the Parks Reserve Forces Training Area. It is located near Santa Rita Jail, which is operated by Alameda County. In 2021 and 2022, the facility was embroiled in a scandal over a permissive and toxic culture of rampant sexual abuse by staff at the facility.

Arroyo Valle or Arroyo Del Valle is a 36.4-mile-long (58.6 km) westward-flowing stream that begins in northeastern Santa Clara County, California, and flows northwesterly into Alameda County where it is dammed to form Lake Del Valle. After that Arroyo Valle is a tributary to Arroyo de la Laguna which in turn flows into Alameda Creek and thence to San Francisco Bay. In the past, the Arroyo Valle had a significant steelhead migration; however, degradation of the stream in the latter half of the 20th century has decimated this anadromous fish population.
