The City of Industry has its sights set on scraping the hillsides clean and constructing several dams along with side (saddle) dams in Tonner Canyon, as well as adding a road along the ridgetop–all of this on top of an earthquake fault.  This land lies in San Bernardino, Los Angeles and Orange Counties and its not contiguous with the City of Industry’s city boundary.
