Flood Hits Marines Harder Than Hussein : Weather: General makes assessment after tour of Pendleton damage. In San Clemente, owners of 34 slide-threatened homes are told they may never move back.

Declaring Mother Nature a far tougher foe than Saddam Hussein, the assistant commandant of the Marine Corps toured this flood-ravaged base Thursday and estimated that damage will total millions of dollars.

“We probably have more damage here as a result of the flood than we did during Desert Storm,” said Gen. Walter E. Boomer, a Persian Gulf War commander.

Boomer said 70 aircraft and other electronic equipment suffered flood damage, as well as two bridges over the Santa Margarita River. In addition, a chapel designated as a California historic site was hard hit.

“My job now is to go back and convince the Congress that we need the money to do the work that needs to be done to put our aircraft and air station back in shape,” Boomer said.

The general said he is convinced that the damage did not result from a lack of preparedness at the base. “Everybody here was watching the river very, very carefully,” Boomer said. “But what happened is that a dike that we did not anticipate giving away gave way. In a matter of 10 to 15 minutes a wall of water” hit the airfield.

Brig. Gen. Don Lynch, base commander, said it would probably take a year for the 120,000-acre base to recover from the flooding.

Among the structures severely damaged was the chapel, built in 1810 as a winery. Its adobe walls were demolished. Lynch said the chapel’s eight stained glass windows were recovered downstream but that religious artifacts on loan from the nearby Mission San Luis Rey were apparently lost.

Boomer characterized the Marines as “lucky” because only 70 of the helicopters and fixed-wing aircraft assigned to the base were on the ground when the flash flood hit. The remaining aircraft were at other sites, including Somalia. Boomer said he thought that of those hit by the flood, only one or two had suffered structural damage to their armaments.

In addition to touring the base, Boomer awarded the Navy Achievement Medal to three privates who had rescued an unconscious Marine from the river during the flood and provided emergency treatment. The Marine is recovering in a hospital.

Meanwhile, in Orange County, dozens of families were forced to stay away from their homes again Thursday as officials continued to monitor the threat of landslides.

Anaheim city employees, working at times over the protests of homeowners, pumped out swimming pools in the upscale Anaheim Hills neighborhood, where rain undermined 45 homes.

Over the past five days, streets and sidewalks have buckled as the neighborhood, which sits atop a recently discovered fissure overlooking the Riverside Freeway, moved downhill at more than one inch per day.

“No one can tell us whether our home will be buried in dirt when we wake up tomorrow morning,” said Lynette Hering. The Anaheim evacuation could last two weeks and maybe longer, authorities said.

And in San Clemente, residents of 34 mudslide-threatened homes were told they might never be able to move back.

“It’s going to be a long time before these people re-enter those houses, if ever,” said San Clemente Fire Department Capt. Jack Stubbs. “And there are a couple of hundred more that could wind up on those lists.”
