Green alley projects are popping up in cities all over the U.S. and Canada in an effort to make the concrete jungle a little better at absorbing rainwater. A new alley program in Los Angeles goes beyond the runoff to actively integrate these unique spaces into the urban fold.
They're all over the city, but you'd hardly know it.
Across Los Angeles, the city's alleyways account for more than 900 linear miles of pavement. If you put them all together, the city's alleys would make up about 3 square miles – about half the size of L.A.'s Griffith Park, twice the size of New York's Central Park, or the equivalent of about 400 Wal-Marts (not including parking). They're peppered throughout the city, in neighborhoods, commercial zones, downtown, and L.A.'s industrial areas. But for the most part, these alleys are ignored.
