Pursuant to this section, the State Geologist shall compile maps delineating the earthquake fault zones and shall submit those maps to all affected cities, counties, and state agencies for review and comment.

The State Geologist shall continually review new geologic and seismic data and shall revise the earthquake fault zones or delineate additional earthquake fault zones when warranted by new information. The State Geologist shall submit all revised maps and additional maps to all affected cities, counties, and state agencies for their review and comment. Concerned jurisdictions and agencies shall submit all comments to the board for review and consideration within 90 days. Within 90 days
