As is true with most natural spaces, rivers have an inherent element of danger to users who do not understand the risks and do not take appropriate precautions. The primary difference to the existing condition of the river is that potentially dangerous hydraulics will be much more apparent to the user and the ability to self-rescue will be substantially improved compared to the recirculating and channel-spanning hydraulics of the low-head dams.
Public safety has been a primary consideration throughout the design of the project. Waves have been located away from bridge piers and in areas of the channel with the easiest access in and out of the river. The orientation of the waves and riffles directs flow away from bridge piers, low-lying pathways, and floodwalls. The design of the river very much considers user interfaces and the concentrated hydraulics are all designed to maintain flushing flows and avoid the dangerous recirculating hydraulics created by the existing dams. Shoreline access is also being developed to allow for self rescue.
Risk is also mitigated through user knowledge, skill level and proper equipment and project design. In-channel users would be encouraged to follow applicable state laws for personal flotation devices, and helmets, cold water protection and other safety measures will be recommended. With any change, we recognize the need for a comprehensive public education campaign to make sure all future river users understand their limits and respect the power of a naturally flowing river.
The City of Grand Rapids and Grand Rapids Whitewater have been working closely with the Grand Rapids Fire Department on the design of the in-river features and emergency access points.
