Three facts:

"Only 7.8 percent of the city is parkspace, making L.A. the most park-poor big city in America."

"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"

"...activity occurs in alleys only about 20 percent of the time—and much of that activity involves either driving or walking through."

The mayor just announced he wants to put 50 pocket parks in LA. Instead of trying to buy expensive developer land, identify at least one alleyway in every neighborhood that can be converted to a pedestrian-only walkway.

-Cost-effective way to create pocket parks; the city already owns the land!
-Promotes car-free access to: business; art; education; urban farming etc.
-Mitigate stormwater runoff
-Maintains existing roads for freight, trash and transport
