Upper Otay Reservoir, also called Upper Otay Lake, is a 20-acre artificial lake in San Diego County, California. It was created in 1959 as a hatchery for the propagation and introduction of Florida Largemouth bass. The reservoir has been open to the public since 1996.In addition to fishing, the site was popular among waterfowl hunters until it was closed to hunting in 2002.
In 2014, the City of San Diego Public Utilities Department, together with the non-profit group Rivers Partners, began restoring the reservoir. The $1.2 million project focused on approximately 100 acres, including five small streams that make up the reservoir's watershed.
Chula Vista is the second-largest city in the San Diego metropolitan area, the seventh largest city in Southern California, the fifteenth largest city in the state of California, and the 75th-largest city in the United States. The population was 243,916 as of the 2010 census, and the estimated population as of 2019 is 274,492. Located about halfway—7.5 miles (12.1 km)—between the two downtowns of San Diego and Tijuana in the South Bay, the city is at the center of one of the richest culturally diverse zones in the United States. Chula Vista is so named because of its scenic location between the San Diego Bay and coastal mountain foothills.

The San Diego Aqueduct, or San Diego Project, is a system of four aqueducts in the U.S. state of California, supplying about 90 percent of the water supply for the city of San Diego. The system comprises the First and Second San Diego Aqueducts, carrying water from the Colorado River west to reservoirs on the outskirts of San Diego. The 70-mile (110 km) First Aqueduct consists of the pipelines 1 and 2, which run from the Colorado River Aqueduct near San Jacinto, California, to the San Vicente Reservoir, approximately 15 miles (24 km) northeast of the city. Pipelines 3 and 4 make up the 94-mile (151 km) Second Aqueduct. Together, these four pipelines have a capacity of 826 cubic feet per second (23.4 m3/s). The smaller, 12.5-mile (20.1 km) Fallbrook-Ocean Branch branches from the First Aqueduct into Morrow Reservoir. The La Mesa-Sweetwater Branch originates from the First Aqueduct, flowing into the Sweetwater Reservoir.

The San Vicente Dam is a concrete gravity dam on San Vicente Creek near Lakeside and 25 km (15.5 mi) northeast of San Diego, California. The dam was built between 1941 and 1943 and created San Vicente Reservoir for the purpose of municipal water storage, flood control and recreation. Although the reservoir is fed by run-off, its main source is the First San Diego Aqueduct. In June 2009, construction to raise the height of the dam by 117 ft (36 m), in order to more than double its reservoir size, commenced. It is the largest dam raise in the United States and largest roller-compacted concrete dam raise in the world. The dam raise project was originally set for the end of 2012, but was completed in early 2014. Efforts to replace the water supply pipelines and prepare the reservoir for the public will be underway until 2015-2017.

Cross Border Xpress (CBX), historically also called the Tijuana Cross-border Terminal and the Puerta de las Californias, is an airport terminal located in the Otay Mesa area of southern San Diego, California, United States, with an access bridge connecting it to the Tijuana International Airport in Tijuana, Baja California, Mexico. It opened on December 9, 2015. It makes Tijuana Airport a geographically binational airport. Unlike the binational airports serving the Swiss cities of Basel and Geneva, the CBX terminal is physically located in the United States but serves an airport whose main terminal and runways are in Mexico. A pedestrian bridge spans the United States–Mexico border, connecting passenger terminals between the two countries. It was the creation of Ralph Nieders, who introduced the concept and infrastructure design in Mexico City in 1989 and San Diego in 1990. The structural scheme allows passengers originating and destined to the United States direct access to the Tijuana airport and equally gives Mexican and international carriers operating from the Tijuana airport direct access to the U.S. passenger market.
The Gate Fire was a wildfire that burned in the Dulzura area southeast of Jamul along Highway 94 in the southern part of San Diego County, California in May 2017. Within the day, the fire spread from an initially reported 10 acres (4.0 ha) to then 1,500 acres (610 ha) in a matter of a few hours, as the fire was pushed by strong winds and dry grasslands mixed with chaparral. The wildfire resulted in evacuation of 500 campers from the Pio Pico RV Resort and Campground. Highway 94 was also closed to the public due to the fire. The fire was named the Gate incident due to its proximity to a landmark pink gate in the Dulzura area.
