Hoffman Marsh is a wetlands on San Francisco Bay in Richmond, California. The marsh has been protected within Eastshore State Park, and adjacent to Point Isabel Regional Shoreline. The marsh is an important nesting ground for wildfowl and stopping ground on the Pacific Flyway, as it is one of only a handful of undestroyed wetlands in the Bay Area. It borders Point Isabel Regional Shoreline and Interstate 80.

Hoffman Channel is a waterway in Richmond, California connecting San Francisco Bay with Hoffman Marsh and Fluvius Innominatus creek which drain directly into the channel. The channel is part of Point Isabel Regional Shoreline, the largest dog park in the United States and serves a swimming are for these animals. Hoffman Channel is adjacent to Point Isabel promontory and was formerly a sandy beach on its south shore.

Fluvius Innominatus (Latin for "unnamed river") or Central Creek is a stream in Richmond and El Cerrito, California, in western Contra Costa County. There is one main source and a secondary unnamed tributary. The creek drains into Hoffman Marsh and then flows into the bay through Point Isabel Regional Shoreline's Hoffman Channel. However, before the area was developed and as early as 1899 the creek had as many as 11 sources which stretched far higher into the Berkeley Hills.

Point Isabel Regional Shoreline in Richmond, California, is operated by East Bay Regional Park District, and is a multi-use park for joggers, windsurfers, kayakers, photographers, picnickers, and people walking dogs. It has access for pedestrians and via public transit, private vehicles, and bikes (although bike-riding within Point Isabel itself is not allowed). It also features a concession offering food for people and grooming for pets. A longtime community organization and nonprofit, Point Isabel Dog Owners and Friends (PIDO), is active in the maintenance and improvement of the park. Point Isabel was closed from March 31, 2020 to June 1, 2020, as a precaution during the early days of the COVID-19 pandemic. Dogs were required to be on-leash during the first week after the reopening but off-leash privileges were restored on June 8, 2020. As throughout East Bay Regional Park District, social distancing measures apply.

Cerrito Creek is one of the principal watercourses running out of the Berkeley Hills into San Francisco Bay in northern California. It is significant for its use as a boundary demarcation historically, as well as presently. In the early 19th century, it separated the vast Rancho San Antonio to the south from the Castro family's Rancho San Pablo to the north. Today, it marks part of the boundary between Alameda County and Contra Costa County. The main stem, running through a deep canyon that separates Berkeley from Kensington, is joined below San Pablo Avenue by a fan of tributaries, their lower reaches mostly in culverts. The largest of these is Middle or Blackberry Creek, a southern branch. The creek is named for Albany Hill, formerly called Cerrito de San Antonio, a prominent (elevation 294 ft.) isolated hill on the shoreline of San Francisco Bay in Albany (The hill is now some distance inland due to Bay fill). Cerrito Creek, joined by a fan of other small creeks, formerly meandered to the Bay through a large marsh just north of the hill.

Point Isabel is a promontory on the eastern shore of San Francisco Bay in the Richmond Annex neighborhood of Richmond, United States.

Pacific East Mall is an Asian mall in Richmond, California. It is owned by Pacific Infinity Company Incorporated.

Albany Beach is a sand beach located in Albany, California on the east shore of San Francisco Bay.

Richmond Annex or The Annex is a neighborhood in southeastern Richmond, California. It is mostly residential and located between San Pablo Avenue/El Cerrito to the east, San Francisco Bay to the west, Central Avenue/Cerrito Creek/Albany Hill/Albany/Alameda County to the south, and Potrero Avenue/Pullman to the north. Carlson Boulevard is the main thoroughfare through the annex, connecting downtown Richmond with downtown El Cerrito. In the segment of San Pablo Avenue that forms the boundary between Richmond and El Cerrito, the buildings on the western side (which are in Richmond Annex) have an El Cerrito postal address and their occupants are sometimes mistakenly described as being in El Cerrito, such as El Cerrito Natural Grocery Company and Down Home Records (formerly Arhoolie Records). According to a local history written down by Fay Breneman circa 1941, "The land now known as Richmond Annex was farmed by the Conlon Brothers." The 1894 map showing the final verdict in Emeric V. Alvarado shows the entire Annex as the property of William Meyer (written on map as "Wm. Meyer"). It was annexed by the City of Richmond on September 26, 1926, after a 13-12 vote on whether to join Richmond or El Cerrito. In recent years, Richmond Annex has been home to the Pacific East Mall, a large collection of Chinese stores, the largest of its kind in the East Bay. Other significant landmarks include: The Richmond Annex Senior Center, which was a firehouse from 1937-1976, and Huntington playground Park. The residents have also rallied successfully for a cell phone tower to not be built, had major input on the Carlson boulevard Interstate 80 overpass mural, and kept Fairmont elementary school in neighboring El Cerrito from being closed.

The Albany Bulb (also simply known as The Bulb) is a former landfill largely owned by the City of Albany, in California. The Bulb is the west end of a landfill peninsula jutting west from the east shore of San Francisco Bay. The term "Bulb" is often used to refer to the entire peninsula, which includes the Albany Plateau, north of Buchanan Street at its base; the high narrow "Neck," and the round "Bulb." The Bulb is part of the City of Albany, and can be reached via Buchanan Street or the Bay Trail along the east side of San Francisco Bay.

Albany Hill is a prominent hill along the east shore of San Francisco Bay in the city of Albany, California. Geologically, the hill is predominantly Jurassic sandstone, carried to the western edge of North America on the Pacific Plate and scraped off there in the course of subduction. Albany Hill is part of a range of hills uplifted long before today's Berkeley Hills. These hills include Fleming Point and Point Isabel (their summits dynamited away), Brooks Island, the Potrero San Pablo, and the hills across San Pablo Strait. Albany Hill's indigenous Ohlone name is unknown. The 1772 Fages expedition referred to the landmark as "El Cerrito," and it was named Cerrito de San Antonio by the Luís María Peralta family after the name of their ranch, Rancho San Antonio, a Spanish land grant which encompassed much of the East Bay. The name was changed to Albany Hill shortly after the city incorporated as Ocean View changed its name to Albany in 1909. The adjacent city of El Cerrito was named after the hill's original Spanish name.

Codornices Creek (sometimes spelled and/or pronounced "Cordonices"), 2.0 miles (3.2 km) long, is one of the principal creeks which runs out of the Berkeley Hills in the East Bay area of the San Francisco Bay Area in California. In its upper stretch, it passes entirely within the city limits of Berkeley, and marks the city limit with the adjacent city of Albany in its lower section. Before European settlement, Codornices probably had no direct, permanent connection to San Francisco Bay. Like many other small creeks, it filtered through what early maps show as grassland to a large, northward-running salt marsh and slough that also carried waters from Marin Creek and Schoolhouse Creek. A channel was cut through in the 19th Century, and Codornices flows directly to San Francisco Bay by way of a narrow remnant slough adjacent to Golden Gate Fields racetrack.
