The Orange County Water District will spend $1.5 million to make sure its facilities will stay standing and operational in case of an earthquake.
"A small investment now may prevent greater loss later," said Dan Griset, president of the district Board of Directors.
The seismic retrofit project will evaluate any deficiencies in the district's buildings, and design changes to bring buildings up to "current earthquake standards."
The project began in February and will be completed in phases over the next two to three years.
The structures proposed for seismic retrofitting include the OCWD and Metropolitan Water District of Orange County Administration Building, the field headquarters in Anaheim and three other agency facilities.
