As long as Rep. Adam Schiff is asking questions of a federal agency related to the Station fire (“We need answers from Forest Service,” July 15), perhaps he can direct another question toward the U.S. Geological Survey (USGS). Does the USGS consider Los Angeles County's Department of Public Works storing of large amounts of storm debris, much of it from the Station fire, at canyon mouths of low risk to public safety?
The Dunsmore Canyon sediment placement site is a good example of where an extensive residential area is located down slope. Following the Station fire, the USGS examined the increased debris flow risk to the foothill communities of the San Gabriel Mountains. USGS geologists and engineering geologists with an expertise in debris flows will have some opinion on this issue that should be presented to the public.
