Yes, just ask to speak with the pool manager. Accommodations will be made!
You said your friend considers themselves as a woman so you have your answer....Woman restrooms/locker-rooms!
I go there often, as I know, they only have male (18+), male (18-), female (18+), female (18-). Those are the only changing rooms I've seen so far. I'm sure if you talk to the people at front desk, they will try their best to accommodate your friend. Good luck.
No, I did not see gender friendly restroom. But you can call to confirm.
Check with management
