California law generally prohibits the construction of buildings directly atop earthquake faults. A building risks catastrophic collapse if it sits on land that splits apart during an earthquake, in which one side of the fault lurches past the other.

In the magnitude 6.6 Sylmar earthquake of 1971, 80% of buildings on land where the fault ruptured the surface suffered moderate to severe damage, while only 30% of buildings constructed a little farther away suffered such damage.

Since 2014, there have been a number of scientific advances made by federal and state scientists in mapping earthquake faults.

In May, the U.S. Geological Survey and California Geological Survey released a 48-page report detailing the latest science of where the Hollywood fault sits, based on a new fault-finding technique called guided wave. It's a technique in which scientists can shoot a sound wave down a suspected surface of the fault, and instruments can verify whether it is indeed a fault.

The technique has proved to be very accurate in identifying the location of faults where they meet the surface, said former state geologist John Parrish.

In the case of the Hollywood Center, test results not only verified the earthquake fault the state mapped as going through the property in 2014, but identified three new, additional and parallel fault strands — all just east of the proposed development, said Parrish, who was chief of the California Geological Survey at the time the study was done.

"Those will go all the way through" and continue west into the Hollywood Center project parcel, Parrish said. "They just didn't run up to the curb and stop. Unfortunately, they're going to go through that piece of property."

One California project that didn't receive the attention of the state agency before it was built was also developed by Millennium Partners: the 58-story Millennium Tower in San Francisco, a $350-million luxury residential project that opened in 2009 but has since started to lean and sink. It will require a costly retrofit to upgrade the foundation — which originally stretched only to a layer of sand, just above a layer of clay — and extend it to bedrock.

"They built it on liquefiable lands ... but they never called us," Parrish said. "So we didn't comment."
