High Profile Investigations of the Hollywood Fault, Hollywood CA
The Hollywood Millennium project is proposed to be developed at, and adjacent to, parking lots the site used by iconic Capitol Records tower building. The fault rupture study performed for the Millennium Hollywood Project, and adjacent sites, is perhaps the most controversial and public fault rupture hazard investigation ever performed in California. The proposal for the Millennium Hollywood project itself pre-dated the publication of the Alquist-Priolo Map for the Hollywood Quad. However, due to intense public opposition and scrutiny, the CGS moved forward with publication of the draft map and utilized the attention to raise funding and awareness. The original basis for the map in the area of the Hollywood Millennium project was based on scant subsurface information and was inferred solely on groundwater data (later dropped by CGS) and presumed fault related topography (also later revised). Group Delta was contracted by 4 adjacent site owners to conduct fault rupture hazard studies using trenches, CPTs, and coring’s. All of the 4 investigations were approved by the City of Los Angeles, in spite of frequent negative public comments from the CGS. The main result of the investigation was that the fault identified by CGS as being active had in fact last been active more the 125,000 years ago; the 4 investigations all showed no active faulting was present. CGS has refused to change the map.
