Los Angeles, Italy

It was placed at what was the then-current edge of the city. East of the dam, the river was crowded into a narrow channel by the city's growth. The Sepulveda Flood Control Basin is a large and undeveloped area in the center of the Valley, used mostly for wildlife refuge and recreation. After the 1938 Los Angeles River flood, the channelization of all the Valley's dry washes was created with dry, concrete-lined river bottoms. Currently these are being devolved...
