SAN DIEGO -- Starting Saturday, the number of fire engine companies at 13 of San Diego's 47 fire stations will be reduced on a rotating basis, as part of budget cuts recently adopted by the City Council.

No fire stations will be closed as a result of the "rolling brown-outs," but fire stations with multiple crews will be reduced to a single crew and their engines will be idled, according to a five-page plan released by the city.

Up to eight fire engines will be taken out of service each day. The firefighters that typically staff those engines will be used to fill in for others who are absent from duty.

The plan will save the city about $11.5 million due to a reduction in overtime.

Councilwoman Marti Emerald said last month the plan could mean it will take longer for first responders to arrive at an emergency.

"These engine closures represent an additional 13 percent reduction in available fire crews and equipment," Emerald said. "We are patching the budget deficit by cutting public safety services. We should all be concerned about this."

According to Emerald, 22 fire stations in San Diego already fall short of a national standard for response times.

The brown-outs were included in Mayor Jerry Sanders' recent plan to close a $179 million budget shortfall. The City Council approved the budget cuts in December.
