Danger posed by earthquake fault (Rose Canyon) will lead to tighter building restrictions

It will soon become harder to develop many properties in San Diego due to growing evidence that the Rose Canyon earthquake fault, which runs beneath the city, is larger and more active than scientists once thought.

The California Geological Survey is creating regulatory fault zones where developers of residential, commercial and public buildings may be required to show that their projects do not sit on top of active faults or are located a safe distance away from such systems.

The zones, which are expected to be adopted this summer, are part of the so-called Alquist-Priolo Act, which is meant to minimize the sort of death and destruction that can occur when an earthquake ruptures the Earth’s surface.

About 7,000 parcels located in and around La Jolla, Old Town, San Diego International Airport and downtown San Diego will be placed in the new fault zones.
