Enhanced Safety Procedures

The following safety and hygiene procedures were in place in 2020. We anticipate procedures will be very similar in 2021. Our protocols will be modified as needed based on guidance provided by health authorities. The procedures that members are expected to adhere to include, but are not be limited to:

  • Check-in with a staff member upon arrival and departure.
  • We will assign spots on the grass for families that are sufficiently distanced from other patrons.
  • Bring your favorite beach chair and blanket to make yourself comfortable.
  • Families are responsible for managing distancing from other groups while in the pool. Lifeguards can’t be responsible for this in addition to ensuring swimmer safety so we will rely on families to help manage responsible use of communal space.
  • You must wear a mask when distancing isn’t possible on the campus grounds. You do not need to wear a mask in the pool but we ask that you maintain physical distance from those not in your family while in the water and on the deck.
  • Carry-in, carry-out policy for trash and all other supplies.
  • Gates to the pool will be marked as an “Entrance” or “Exit.” Traffic on pool deck will be one-way.
  • We will not provide any shared equipment such as rings, goggles, or noodles.
  • Bathrooms and showers will be open but locker areas and water fountains will not be. We will maintain a one-in, one-out policy for restroom use and ask that you utilize hand sanitizer before entering the building. 
  • The restrooms and outdoor facilities will be cleaned during the day.
  • Swimming lessons are not permitted until Phase III of the reopening plan so guards are not able to teach children at the pool.
