A recent survey of every swimming pool in the Los Angeles Basin found that Beverly Hills has the most pools and Watts has none.
The digital analysis called the "Big Atlas of L.A. Pools" fills 6,000 pages in 74 printed volumes.
It concludes that the typical swimming pool in Los Angeles is oval-shaped and measures 16 feet, 4 inches by 33 feet, 6 inches, though there are numerous oddly shaped pools squeezed into backyards.
The atlas found that Beverly Hills has 2,481 — the highest per capita in the region. Long Beach boasts 2,859 pools, Rancho Palos Verdes 2,592. It could not come up with a total for the city of Los Angeles, because the count left out the San Fernando Valley. The Brentwood section of the city, though, has 1,920.
But two other Los Angeles neighborhoods have no backyard pools at all: Watts and Florence. Of the four public pools in area parks, three apparently were closed for the season and empty when the satellite photo was taken, said Catarah Hampshire, a spokeswoman with the Los Angeles County Department of Parks and Recreation.
The survey was the work of German graphic designer Benedikt Gross and Joseph Lee, a UCLA graduate who was at Massachusetts Institute of Technology as a research assistant.
