Tijuana - Geography

Geography

Tijuana is the western-most city in Mexico, and consequently in Latin America, and the 3rd largest city of northern Mexico. Located approximately 210 kilometres (130 mi) west of the state-capital, Mexicali, the city is bordered to the north by the cities of Imperial Beach, San Diego, and unincorporated territory of western San Diego County. To the southwest of the city is Rosarito Beach, while to the south is unincorporated territory of Tijuana Municipality. The city is nestled among hills, canyons, and gullies. The central part of the city lies in a valley through which flows the channeled Tijuana River.

Housing development in the Tijuana Hills has led to eradication of many seasonal mountain streams. This lack of natural drainage makes places within the city vulnerable to landslides during the rainy season. The varied terrain of Tijuana gives the city elevation extremes that range from 0 metres (0 ft) to 790 metres (2,590 ft).

Tijuana is noted for its rough terrain, which includes many canyons, steep hills, and mesas. Among noted canyons in Tijuana are Canyon K and Canyon Johnson. Large Tijuana hills include Red Hill (Cerro Colorado) and Hill of the Bees (Cerro de las Abejas) in the eastern part of the city.

The city is located near the terminus of the Tijuana River and within the Tijuana River Basin. The Tijuana River is an intermittent river, 195 km (121 mi) long, on the Pacific coast of northern Baja California in Mexico and Southern California in the United States. It drains an arid area along the California–Baja California border, flowing through Mexico for most of its course and then crossing the border for the last 8 km (5 mi) of its course where it forms an estuary that empties into the ocean. The river's lower reaches harbor the last undeveloped coastal wetlands in San Diego County, and some of the last in Southern California, amidst a highly urbanized environment at the southern city limits of Imperial Beach.

As Downtown Tijuana was built at the bottom of the river valley, the district is subject to seasonal flooding created by drain-off from the Tijuana Hills. During this time, east-bound portions of the Via Rapida (east-west highway) may be blocked off by the Tijuana Police due to hazardous conditions.
