Salt Pier diving- Status ? Open or closed or permission only and from whom ?

Are there any notable shore dive locations that are closed ? I know this is vague but if there's any notable closures in the past 10 years I'd appreciate hearing about them, as well as any complications for that affect parking or access. Things change but I'd appreciate knowing which sites are currently not diveable ( say, compared to the earlier editions of Shore Diving Made Easy )

Any recent tips regarding diving up the in the Park ?
