Fortunately there have been modifications to CEQA last year to prevent these abuses of the law that result in worse environmental outcomes (students driving long distances rather than living on campus)
There is another solution to this!
No need. We're solving a narrow problem: students' need to park on campus. Out-of-town commuter and part-time students will need a car. But everyone else is solvable.
Stop trying to solve the problem for California. Focus on the narrow problem. Universities everywhere operate as a parallel population.
UCSC is an enclave on a hill with limited transport routes to downtown or the rest of the world. And the UCSC leadership has its hands tied by many different things; they can't just say "OK no cars on campus except if you are a commuter".
Right, this is how you solve it. (Most students don’t need a car parked on campus to get to the rest of the world from Santa Cruz.)
