Boulder, Colorado is embroiled in a legal battle with the Federal Aviation Administration (FAA) over its intent to close the local airport. The city argues that federal grant requirements obligating them to maintain the airport are unconstitutional.
The dispute centers around Boulder’s receipt of federal funds for the airport, including a grant from 65 years ago used to purchase land. This triggers a clause mandating the airport's operation in perpetuity unless the FAA releases Boulder from these obligations. Despite ceasing to accept grants with plans to shut down the facility by 2040, Boulder claims it should not be compelled to keep an airport on land funded by FAA money.
“Clearly requiring that an airport taking federal airport funds be used as an airport is a strong nexus, proportionate to the project, and no otherwise-violative of constitutional rights,” states one argument.
