I'm on the board for the pool I belong to. We have been working on plans for the possibility we will open with rules in place that follow the guidelines.
For small neighborhood pools the list is daunting. One of the bigger issues is enforcement. Pools are mostly staffed with teenagers. they will now be asked to do things above and beyond what they are supposed to do. Training, supplies, cleaning, etc, etc, etc.
And the policing they might have to do opens such a can of worms. We live in an age of entitlement where members don't want to listen and be told when they are doing or their kids are doing something wrong.
It is a massive headache and without clear guidance from the health dept the planning for opening has been a nightmare.
