The Naperville Park District (“Park District”) is committed to providing safe aquatic facilities and programs and holds the safety of participants in high regard. The Park District continually strives to reduce such risks and insists that all participants follow safety rules and instructions that are designed to protect the participants’ safety. However, participants and parents/guardians of minors engaged in aquatic activities must recognize that there is an inherent risk of injury.

You are solely responsible for determining if you or your minor child/ward are physically fit and/or adequately skilled for the activities associated with this Reservation for Centennial Beach (“group reservation”). It is always advisable, especially if the participant is pregnant, disabled in any way or recently suffered an illness, injury or impairment, to consult a physician before undertaking any physical/aquatic activity.

Please understand and recognize that adult patrons and parents/guardians of minor patrons are primarily responsible for assessing their respective swimming skills. Further, parents/guardians of minor patrons must understand that it is the parent/guardian’s sole responsibility to provide adequate and qualified supervision for any and all activities contemplated by this agreement and Beach Group Reservation.  Adult patrons and parents/guardians of minor patrons must further understand and recognize that lifeguards are not responsible for providing supervision; rather, lifeguards are responsible for enforcing safety rules and responding to emergencies.

Warning of Risk 

Swimming and other aquatic activities challenge and engage the physical, mental and emotional resources of each participant. However, despite careful and proper preparation, instruction, medical advice, conditioning and equipment, there is still a risk of serious injury, including but not limited to drowning, head/brain injury, and spinal cord injury. Understandably, not all hazards and dangers can be foreseen. The very nature of swimming and aquatic activities are hazardous and risky, including but not limited to fatigue and overexertion, poor swimming skills, failing to avoid dangerous areas, failing to follow rules and regulations, failure of lifeguards to locate victims and/or delay in emergency response time, horseplay, diving or cannon-balling into shallow water and striking the bottom or side of the Beach or waterslide, inadequate supervision or instruction, lack of conditioning, becoming disoriented, striking other swimmers, striking one’s head on the bottom or sides, slip and falls on the deck or within the Centennial Beach facility, chemical exposure, exposure to communicable disease arising out of a group activity in general, and all other circumstances inherent to aquatic activities. In this regard, it must be recognized that it is impossible for the Park District to guarantee absolute safety.
