I believe the stormwater tank and pumps are capable of handling a 100 year flood event. I don't see them allowing the tunnel to flood by design, especially with the future consideration of a LRT line going through it.
The electronic access system could be a security measure, preventing vehicles from accessing it if there is a back up (keep cars from stopping inside) or emergency event like a fire.
