Officers destroyed about 20,000 marijuana plants, which they valued at about $60 million, in raids on two foothill gardens near Page Mill Road in Palo Alto and on Midpeninsula open space on 5 August 2009.[1] Palo Alto police SWAT officers joined the Santa Clara County sheriff’s marijuana-eradication team and state fish and game agents to sweep both gardens and remove the plants.[1] No one was arrested; officers found several unoccupied camps, signs of unauthorised hunting, two bags of ammunition and a Taser-style weapon.[1]

A later account of the county’s summer campaign described a July eradication off Page Mill Road at the same size and street value, and said the July raid had turned up a loaded 12-gauge shotgun.[2] The sheriff’s office had already destroyed about 220,000 plants that season, up from 190,000 the year before.[2]
