Rio Vista (Spanish: Río Vista, meaning "River View") is a city located in the eastern end of Solano County, California, in the Sacramento River Delta region of Northern California.^[8] The population was 7,360 at the 2010 census.

Geography

Rio Vista is a small city in Solano County approximately 50 miles (80 km) south of Sacramento, on the Sacramento River in the Sacramento River Delta.

According to the United States Census Bureau, the city has a total area of 7.1 square miles (18 km²), of which, 6.7 square miles (17 km²) of it is land and 0.4 square miles (1.0 km²) of it (5.68%) is water.

Climate

According to the Köppen Climate Classification system, Rio Vista has a warm-summer Mediterranean climate, abbreviated "Csa" on climate maps.^[9]

Origin and history

The present location of Rio Vista town center is several miles south of the original settlement. Colonel Nathan H. Davis founded "Brazos del Rio" near the entrance of Cache Slough at the Sacramento River, on the Rancho Los Ulpinos Mexican land grant, in 1858. The settlement was renamed "Rio Vista" before a flood in 1862 that resulted in the town moving to its present location on higher ground. The city's name combines the Spanish words for "river" and "view." Post authorities established office in 1858.^[10] The community was officially incorporated as Rio Vista on December 30, 1893. The newspaper of record there was the River News-Herald and Isleton Journal,^[11] established in 1890.^[12]

Army facility at Rio Vista

From 1911 through 1992 Rio Vista was home to the United States Army Reserve Center, Rio Vista. The facility was initially established as a base for river control activities by the U.S. Army Corps of Engineers. During the 1950s it was used by the U.S. Army Transportation Corps to store and maintain harbor craft, and during the 1960s and 1970s it was used to prepare amphibious vehicles for transportation to Vietnam and to train troops in their use. In 1980 it was transferred to the U.S. Army Reserve and in 1992 it was closed due to a BRAC decision. The town also hosts a United States Coast Guard station, established in 1963.^[13]

Humphrey the humpback whale

Rio Vista was visited by a lost humpback whale in 1985, despite being 60 miles (97 kilometers) up the Sacramento River from the Pacific Ocean. The young whale, nicknamed "Humphrey", attracted throngs of curiosity seekers before he was eventually guided back to sea by rescuers. The Army Reserve Unit (481st Transportation Company (Heavy Boat)) was activated to use their vessels (Landing Craft Utility (LCU)) to assist in the guiding of Humphrey back to the sea. Again in May 2007, humpbacks were sighted in Rio Vista. "Delta" and "Dawn," mother and calf, stopped at least twice in the river near the town.

Flannery land purchases

In 2018, a group of investors called Flannery Associates, a subsidiary of California Forever, began purchasing most of the land surrounding Rio Vista and suing those refusing to sell Flannery their land for "constraint of trade."^[14]^[15]^[16]

Industry

Natural gas was discovered in the Rio Vista area in 1936^[19] and the Rio Vista Field, (RVGU Rio Vista Gas Unit ) at one time there was a gas well behind RV City Hall in the middle of boat launch parking lot. Amerada Hess Corporation was the first major operations. When Amerada sold out to Sheridan Energy another buy out would soon take shape by Calpine Natural Gas. Calpine fell into the energy collapse when Enron went under then Calpine sold off a majority of its natural gas holdings to Rosetta Resources. Next buyer was Vintage Petroleum who sold out to and currently running operations California Resources Corporation as of 2022. Same address since 1936. Rio Vista Gas Unit was the largest natural gas field in California, became a major source of employment for the remainder of the 20th century. Other industries include agriculture, manufacturing and tourism. There are over 750 wind turbines belonging to the three renewable energy projects (Shiloh Wind Power Plant, NextEra Energy Resources' High Winds Energy Center and one owned by the Sacramento Municipal Utility District) on the Montezuma Hills, close to the city. There are plans to add an additional 200 wind turbines.

Rio Vista is home to the largest American producer of Belgian Endive^[20] in the United States. Craig Breedlove, five-time world land speed record holder, lived in and had an engineering facility in the city.

The city is served by Rio Vista Municipal Airport and is situated along the Rio Vista Highway (SR 12) between Fairfield and Lodi. The highway crosses the Sacramento River via the Helen Madere Memorial Bridge, colloquially known as the Rio Vista Bridge.
