    “Shade was integral, and incorporated into the urban design of southern California up until the 1930s,” [Mike] Davis said. “If you go to most of the older agricultural towns … the downtown streets were arcaded. They had the equivalent of awnings over the sidewalk.” Rancho homes had sleeping porches and shade trees, and buildings were oriented to keep their occupants cool. The original settlement of Los Angeles conformed roughly to the Law of the Indies, a royal ordinance that required streets to be laid out at a 45-degree angle, ensuring access to sun in the winter and shade in the summer (…)

    All that changed with the advent of cheap electricity. In 1936, the Los Angeles Bureau of Power and Light completed a 266-mile high-voltage transmission line from Boulder Dam (now Hoover Dam), which could supply 70 percent of the city’s power at low cost. Southern Californians bought mass-produced housing with electric heating and air conditioning. By the end of World War II, there were nearly 4 million people living in Los Angeles County, and the new neighborhoods were organized around driveways and parking lots. Parts of the city, Davis said, became “virtually treeless deserts.”
