Arboretum Waterway Maintenance and Enhancement Project

Phase One of the Arboretum Waterway Maintenance and Enhancement Project begins in February 2017. This first phase extends from the eastern terminus of the waterway and ends before Lake Spafford. To learn more about future phases read our FAQ below.


We are excited to announce that next year we are starting a multi-year project to maintain and enhance our campus waterway. The waterway is not just iconic to the Arboretum, it’s an amenity for our community, and an important component to how our campus manages its stormwater.

The last time we maintained the waterway to improve issues such as sediment build up — the kind which naturally occur in ponds like this — was almost 20 years ago. This time the work will be similar, but in addition, we are engineering in features that will add movement to the water, updating the pathways to bring them up to modern accessibility standards, as well as addressing other safety concerns. (Learn more by reading our FAQ.)

Thank you for your patience as construction takes place. We look forward to keeping you up to date as we make progress on this project and hope that you will visit this page often to learn how engineers are re-designing the waterway to improve its future maintenance, aesthetics and habitat value, to stay informed about the timing and location of detours, as well as to find out how you can help!
