These included explosives warehousing, gas works, oil-drilling, slaughterhouses, and tanneries.
Los Angeles City Council also designated seven industrial zones within the city.
On September 14, 1908, Los Angeles City Council promulgated residential and industrial land use zones.
First, the 1908 laws did not establish a comprehensive zoning map as the 1916 New York City Zoning Ordinance did.
Second, the residential zones did not distinguish types of housing: it treated apartments, hotels, and detached-single-family housing equally. During World War II, Los Angeles was a major center of wartime manufacturing, such as shipbuilding and aircraft.
The completion of the Los Angeles Aqueduct in 1913, delivering water from Eastern California, later assured the city's continued rapid growth.
Nicknamed the "City of Angels" partly because of its name's Spanish meaning, Los Angeles is known for its Mediterranean climate, ethnic diversity, and sprawling metropolis.
