Flights louder than 89 decibels can’t fly in and out of San Jose from 11:30pm to 6:30am without violating current airport rules. Airlines risk a $2,500 fine and, if a tenant at Norman Mineta San Jose International Airport, they could face eviction if found in repeated violation. The whole curfew conversation came up last week, when downtown Councilman Sam Liccardo asked to delay a City Council vote on a proposed $82 million addition to the airport. Signature Flight Support, whose proposal involves a massive new facility that will house Google’s executive jet fleet, doesn’t think it’s fair for the lease language to allow the city to evict the company over a single curfew violation.
