The San Bernardino meridian, established in 1852, is one of three principal meridians in the state of California. Because of the state's shape, three meridian–baseline sets are required for surveys in all parts of the state. The San Bernardino meridian is used for Southern California, and some townships in Arizona are also referenced to it.The initial point (datum) is at the summit of Mount San Bernardino, in the San Bernardino Mountains, in San Bernardino County, California. It is at an elevation of over 10,000 feet (3,000 meters). The meridian runs north–south from the initial point 34°07′13″N 116°55′48″W.

The Henry Washington Survey Marker is a survey marker in San Bernardino National Forest in San Bernardino County, California. The marker served as the earliest initial points of the San Bernardino Baseline and Meridian, which in turn mark the starting points for the surveying and subdivision of land in Southern California. Colonel Henry Washington placed the marker in 1852 at the beginning of the U.S. Surveyor General's Office's land survey of Southern California, the first survey of the region. Later surveys in 1897 and 1907 set new initial points for the survey east and west of the marker; these points replaced Washington's marker as the official initial points in 1917. Washington's original marker nonetheless still serves as a point along the baseline.The marker was added to the National Register of Historic Places on May 12, 1975.

Seven Oaks Reservoir is a reservoir on the Santa Ana River in San Bernardino County, California, about 8 miles (13 km) northeast of the city of Redlands. The reservoir is formed by Seven Oaks Dam, which was completed in 1999. The United States Army Corps of Engineers built the zoned earth-and-rock-fill dam at the foot of the San Bernardino Mountains to protect against flooding in the eastern portion of the Greater Los Angeles Area. Its maximum height is 550 feet (170 m) above the pre-existing streambed and 650 feet (200 m) above the lowest portion of the foundation. The reservoir is medium-sized at 147,970 acre-feet (182,520,000 m3), though it is a bit large for a reservoir whose sole purpose is flood control, which means that water is released as soon as safely possible, while still slow enough to allow water to seep into the streambed, recharging the groundwater aquifer. Also, releases are coordinated with Prado Dam, which is 40 miles (64 km) downstream.

Seven Oaks Dam is a 550-foot (170 m) high earth and rock fill embankment dam across the Santa Ana River in the San Bernardino Mountains, about 4 miles (6.4 km) northeast of Redlands in San Bernardino County, southern California. It impounds Seven Oaks Reservoir in the San Bernardino National Forest. The dam was proposed in response to major floods in the mid–20th century, and was constructed between 1993 and 2000. Seven Oaks is a dry dam that serves mainly for flood protection to Orange, Riverside and San Bernardino Counties, although it also used to impound water for groundwater recharge. One of the largest embankment dams in the United States, the dam was built under contract from the U.S. Army Corps of Engineers (USACE) by Odebrecht Corporation of California, a subsidiary of the Brazilian firm Contructora Norberto Odebrecht,. The dam is now owned and operated by local flood control districts.
