Sonoma County sheriff's officials, still sifting through reports and findings from a massive raid on home marijuana gardens in southwest Santa Rosa, said Thursday that authorities yanked a total 1,150 plants weighing more than 15,000 pounds in Wednesday's daylong operation.

Ninety-six pounds of processed marijuana, worth about $2,000 a pound on the street, also were confiscated, Sonoma County Sheriff's Lt. Dennis O'Leary said.

The total value of the pot seized likely exceeded $2.5 million by that accounting.

Officers also recovered a half-pound of cocaine, five grams of methamphetamine, six firearms -- including a rifle with a silencer -- and more than $20,000 in cash during the multi-agency effort to rid one neighborhood of what authorities said were gardens at a large majority of the homes.

"Literally every backyard in that neighborhood, except for maybe half a dozen, all had grows in them," Lt. Dennis O'Leary said.

About 150 law enforcement personnel in protective gear swooped down on the neighborhood south of Corby and Bellevue avenues, targeting modest homes along four connected streets between the railroad tracks and Moorland Avenue.

O'Leary said 33 search warrants were served, and 15 people were arrested on a variety of drug-related charges in the raid, which involved the FBI, the Drug Enforcement Agency, the Department of Homeland Security, CHP, Santa Rosa police and Sonoma County sheriff's deputies, as well as personnel from the county probation and district attorney's offices.
