Variability from year to year can be dramatic: in the wettest years of 1883/1884 and 1940/1941, more than 24 inches (610 mm) fell, whilst in the driest years there was as little as 3.2 inches (80 mm). The wettest month on record is December 1921 with 9.21 inches (234 mm). Snow in the city is rare, having been observed only six times in

7548-465: The importance of its neighborhoods when it organized its 2008 General Plan around the concept of a "City of Villages". San Diego was originally centered on the Old Town district, but by the late 1860s the focus had shifted to the bayfront, in the belief that this new location would increase trade. As the "New Town" – present-day Downtown – waterfront location quickly developed, it eclipsed Old Town as
7650-481: The inflation rate in this era of high inflation; the reluctance of one governor after another to raise fuel taxes in accordance with inflation meant that California ranked dead last in the United States in per capita transportation spending by 1983. During the 1980s and 1990s, Caltrans concentrated on "the upgrading, rehabilitation, and maintenance of the existing system," plus occasional gap closure and realignment projects. For administrative purposes, Caltrans divides
7752-425: The majority of San Diego's current area was originally occupied on the west by coastal sage scrub and on the east by chaparral , plant communities made up mostly of drought-resistant shrubs. The steep and varied topography and proximity to the ocean create a number of different habitats within the city limits, including tidal marsh and canyons . The chaparral and coastal sage scrub habitats in low elevations along
7854-425: The median is 9.6 inches (240 mm). The months of December through March supply most of the rain, with February the only month averaging 2 inches (51 mm) or more. The months of May through September tend to be almost completely dry. Although there are few wet days per month during the rainy period, rainfall can be heavy when it does fall. Rainfall is usually greater in the higher elevations of San Diego; some of
7956-413: The mesas, while leaving the urban canyons relatively wild. Thus, the canyons give parts of the city a segmented feel, creating gaps between otherwise proximate neighborhoods and contributing to a low-density, car-centered environment. The San Diego River runs through the middle of San Diego from east to west, creating a river valley that serves to divide the city into northern and southern segments. During
8058-457: The mission proper. Mission San Diego was the southern anchor in Alta California of the historic mission trail El Camino Real . Both the Presidio and the Mission are National Historic Landmarks . In 1821, Mexico won its independence from Spain , and San Diego became part of the Mexican territory of Alta California .

San Diego and its backcountry suffer from periodic wildfires. In October 2003, San Diego was the site of the Cedar Fire , at that time the largest wildfire in California over the past century. The fire burned 280,000 acres (1,100 km ), killed 15 people, and destroyed more than 2,200 homes. In addition to damage caused by
8568-401: The original façades to retain the architectural style. The menagerie of exotic animals featured at the 1915 exposition provided the basis for the San Diego Zoo . During the 1950s there was a citywide festival called Fiesta del Pacifico highlighting the area's Spanish and Mexican past. In the 2010s there was a proposal for a large-scale celebration of the 100th anniversary of Balboa Park, but
8670-462: The plans were abandoned when the organization tasked with putting on the celebration went out of business. The southern portion of the Point Loma peninsula was set aside for military purposes as early as 1852.

The city's population grew rapidly during and after World War II, more than doubling between 1930 (147,995) and 1950 (333,865). During the final months of the war, the Japanese had a plan to target multiple U.S. cities for biological attack , starting with San Diego.

The first European to visit the region was explorer Juan Rodríguez Cabrillo , sailing under
9078-411: The roads of the state and making recommendations for their improvement. At the time, there was no state highway system, since roads were purely a local responsibility. California's roads consisted of crude dirt roads maintained by county governments, as well as some paved streets in certain cities, and this ad hoc system was no longer adequate for the needs of the state's rapidly growing population. After
9180-478: The site of present-day downtown San Diego . Residents and businesses quickly abandoned "Old Town" for Horton's "New Town" because of New Town's proximity to shipping.

Households made up of individuals account for 28.0%, and 7.4% had someone living alone who
9588-571: The town every night. The Californios drove cattle away from the pueblo hoping to starve the Americans and their Californio supporters out.

Their joint command of 150 men, returning to San Diego, encountered about 93 Californios under Andrés Pico . In
9690-493: The urban core. According to data from the Downtown San Diego Partnership, the number of individuals living outside or in vehicles has reached a two-year low, standing at approximately 1,200 as of last month. The decrease is attributed to the implementation of the city's camping ban and the concerted efforts to establish new shelters. While enforcement has led to relatively few individuals being punished,
9792-460: The vote. Beyond the town, Mexican land grants expanded the number of California ranchos that modestly added to the local economy. (See, List of pre-statehood mayors of San Diego .) However, San Diego had been losing population throughout the 1830s, due to increasing tension between the settlers and the indigenous Kumeyaay and in 1838 the town lost its pueblo status because its size dropped to an estimated 100 to 150 residents. The ranchos in
