- Baldwin Hills Reservoir
The Baldwin Hills Reservoir was a man-made water storage basin located on a low hilltop in
Baldwin Hills, Los Angeles, California . It was constructed between 1947 and 1951 by theLos Angeles Department of Water and Power on a small activefault line . The design consisted of four layers above the rock foundation: an asphalt lining, a gravel drain basin, compacted clay, and a final asphalt layer on the top. The fault lines were considered during planning.Failure
On
December 14 ,1963 , a small crack developed in the reservoir wall. The surrounding portion of the wall was quickly eroded straight through, emptying 250 million gallons of water into the surrounding neighborhood in a few hours. In the process, 277 homes were destroyed and 5 lives were lost. Frantic rescue efforts avoided a more significant loss of life. The reservoir failure was attributed tosubsidence caused by over-exploitation of the nearbyInglewood Oil Field .The reservoir is now land and now part of
Kenneth Hahn State Recreation Area .External links
