and being located at one end of the metropolitan area, together with Vitacura it leads the rate of motorization per capita (motor vehicles per inhabitant) in Greater Santiago. It was expected that by 2020, Lo Barnechea will have 3 stations of the Las Condes Tramway, which would give it a historic connection to the Santiago Metro, being currently one of the three communes of Greater Santiago (along with La Pintana and Lo Espejo) that does not have stations of the metropolitan railroad. However, the project was canceled by the authorities for not having the necessary subsidies for its execution. Lo Barnechea was also part of the Transantiago feeder zone C, together with the districts of Providencia, Las Condes and Vitacura. It is currently served by units 4 and 6 of this transportation system. There is an elevator on Cerro 18 operated by the Municipality of Lo Barnechea that connects this sector with Los Quincheros Street and the top of the hill, where the Parque de la Chilenidad is located.

It is estimated that in a mountainous environment, rainfall increases by about 22 mm every 100 m of altitude, while the temperature decreases by about 0.5 °C every 100 m. According to this, being the urban area of the town of Lo Barnechea located at 850 m a.s.l., it receives 65 mm more rainfall than in the commune of Santiago. This varies according to the size of the rural territory of the commune. In the annual distribution of rainfall, and considering the entire mountainous area, when it rains several days in a row, large flows are produced in the riverbeds, which causes flooding by accumulation and its consequent transfer according to slopes (1982-84-87). The impact was regrettable, with loss of life, interruption of activities, damage to infrastructure and equipment, due to the permanence of inhabitants on the banks of the Mapocho River. In addition to the reality of the Mapocho River and its location, there is a natural climatic
