Rent Our Space

Consider our Platinum LEED Certified Watershed Center for your next event. The Watershed promotes a sustainable, low waste, environmentally friendly venue. We have a variety of spaces available for private, non-profit and corporate events.

“The facilities are beautiful and unique. The staff were incredibly helpful and genuinely invested in making sure we had an amazing experience. All our guests commented on what a fun and interesting location it was. We also got extremely lucky and got to experience an evening illuminated by countless fireflies. It’s a fun, quirky and socially conscious venue that deeply impressed us.
