Ketcham said that Outside Lands' sound engineers who adjust the volume on site worked to mitigate the issue last year, and complaints dropped from 118 on Friday to only 31 on Sunday. Still, she said the festival and city plan to do more. The permit extension requires a minimum amount of noise monitors, who will report out the adjustments they make after the festival is over.
"When questions come in saying 'You don't know if they did anything,' we'll have a report showing exactly what they did," Ketcham said.
Several local residents spoke at the hearing in support of Outside Lands, including musicians, parents, teachers, business owners and union workers.
"Every single year [the festival] has improved. They've gotten better at traffic, noise, litter, the cleanup," said longtime Richmond District resident Jason Hancock.
"Outside Lands is a continuation of the history of rock 'n' roll going on in San Francisco since 1968," said Douglas Taylor, a stagehand who works at the festival. "Outside Lands goes above and beyond anyone I've ever seen in dealing with complaints."
The Board of Supervisors voted unanimously to extend the festival's permit. Outside Lands is slated to return to Golden Gate Park Aug. 9–11 with Paul Simon, Childish Gambino and Twenty One Pilots as headliners.
