Bethel Island is an island in the Sacramento–San Joaquin River Delta of Contra Costa County, California, approximately 10 kilometres (6.2 mi) east of Antioch. The island describes itself as "the heart of the California Delta."

Bethel Island (formerly known as Bethell, Bethell Ranch, Bethel Tract, Sand Mound Ranch, Sand Mound Tract) is also a census-designated place (CDP) on the island. The population at the 2010 census was 2,137, a 7.6 percent decline from 2,312 at the 2000 census. The community of Bethel Island is governed as a Special Act District created by the California State legislature and named the Bethel Island Municipal Improvement District (BIMID). It is a popular destination for recreation seekers, especially hunters, fishermen and boaters.

History

Bethel Island was named for the Bethell Brothers, Frank and Warren Bethell, who formed the first successful farm on the island, called Sand Mound Ranch. Frank Bethell was appointed postmaster of the first post office; however, a pious clerk at the U.S. Postal office did not want the name "Bet Hell" and dropped the additional "L" to make it "Bethel", like the Hebrew term בית אל beth el which translates to "House of God," is known for its recreational activities. The island's reputation as such began in 1930, with Blanche and Jack Farrar founding a park with swimming, picnicking and other outdoor activities. This park would eventually be called Farrar Park. Remsburg Marina was started by Warren Remsburg in 1938, and in 1944 a fishing resort called Frank's had gained popularity on the island. The resort was built by the Andronico family. By the 1950s the area became popular with sport fishermen and the rich. Frank Bethell and Warren Bethell's widow, Ann Youree (Hamilton) Bethell sold their interest in the island in 1901. Ann went on to form a successful ranch in Almaden Valley and established the Bethell Block in downtown San Jose (site of the current Federal Building).

Governance

The Bethel Island Municipal Improvement District (BIMID) has five directors, elected from the local community. They are responsible primarily for maintaining the levee around the island. They also have responsibilities for water supply and drainage; parks and playgrounds; and the local airports.

BIMID was created by the California State Legislature in 1960, replacing Reclamation District No. 1619. BIMID owns 100 acres (40 ha) of land in the center of the island between Bethel Island Road and Piper Road. Appromiately 85 acres (34 ha) is used for sourcing sand to maintain the levee; plus approximately 15 acres (6 ha) used to plant new trees to mitigate for tree removal elsewhere on the island.

The BIMID property on Stone Road consists of the District offices, a meeting room and a small equipment yard.

The island is mostly below sea level, with a 14.9 mile perimeter levee. The area is home to approximately 3,700 people, with 1,300 residential houses on the island, plus four mobile home parks, 13 commercial marinas, a commercial business area and agricultural land.
