History Channel Interviews Dr. Ed Medley Regarding the San Francisco Sea Cliff Incident

OAKLAND — The History Channel featured an interview with Dr. Ed Medley , PE, CEG, F.ASCE, currently of Geosyntec's Oakland office, about the failure investigation of the San Francisco Sea Cliff Incident in December 1995. The interview aired on the network's " Shockwave " program (Episode 12) on Friday, February 29, 2008 at 9 p.m. (EST and PST) with a repeat broadcast on Saturday, March 1, 2008 at 1 p.m. (EST and PST).

The Sea Cliff Incident was a series of related events which followed the catastrophic failure of a 100-year-old sewer during a rain storm. The sewer failure resulted in the erosion of a 240-foot-diameter and 40-foot-deep pit which destroyed over $30 million of private and public property. Working for the City of San Francisco, Dr. Medley was the Principal Investigator for the Failure Analysis Associates (Exponent) team that unraveled the complex set of factors leading to the Sea Cliff Incident. He has summarized the Sea Cliff Incident and the failure investigation in technical papers, including "Forensic Investigation of the Failure of an Interceptor Sewer, Sea Cliff Area, San Francisco, California" and in previous television documentaries.
