Indoor/Outdoor Pool

We're wrestling with the walkoff mat requirement for a recreation center where there is an indoor/outdoor pool - one end of the pool and the roof retract during clement weather to provide an outdoor pool experience, yet the pool area is fully enclosed during cold weather. there is a concrete floored office and lifeguard lounge accessed only from the pool area, and swimmers all must walk through a locker room and shower before walking onto the pool deck. there is a small exterior zone outside of the pool enclosure surrounded by a fence and accessible only from the pool area. A strict reading of the credit requirements would have us placing walkoff mats everywhere, even in areas that are not accessible to the rest of the building which seems a bit odd. We have walkoff mats located at the two building entrances.
