According to the Los Angeles Times, in the 20 years following the signing of the AP act, the California Geologic Survey published more than 500 fault maps which informed developers and cities where earthquake faults were located. However, due to budget restrictions, only about 20 were drawn in the following two decades.

 

As of 2014, approximately 300 more maps remain to be drawn. In January 2014, in his proposed budget to lawmakers, Governor Jerry Brown has requested $1.49 million for fault mapping in the 2014-2015 fiscal year and an additional $1.3 million in annual dedicated funding through increased building permit fees. This funding would increase the number of scientists working on fault mapping and accelerate the pace of completion of this project.
