Community Pool - Can we get rid of lifeguards?

I'd like to find more information about the possibility of changing our HOA pool access. A nearby subdivision did this years ago to much success, but I have been unable to find someone to tell me how it was done. Currently, we must have two lifeguards on duty for all hours that the pool is open. (If someone rents the pool for a private party, they must hire at least two lifeguards as well). What happens all too often is that a lifeguard doesn't show up, the lifeguard company has nobody else they can send, and the pool can't open, leaving quite a few Houston kids disappointed. How can we go about having electronic card access without lifeguards? I've brought it up to the board before but all they say is the insurance would be too high. Where can I find what the laws are about this type of thing and how to go about implementing it?

Thanks, Steve. How do I get in touch with "City Code Enforcement"? Do I contact the local Sherriff's office, or the Mayor, or City Hall... ?
