The Confluence Center of Colorado, 2600 Dos Rios Drive, will host its grand opening Nov. 5, 11 a.m. to 1 p.m.

The six nonprofit organizations that are occupying the building are: RiversEdge West; EUREKA! McConnell Science Museum; One Riverfront; Colorado National Monument Association; Colorado West Land Trust; and Colorado Canyons Association.

The grand opening will feature:

• Paper Chain Cutting – STREAM Preschool students from EUREKA! will lead a “ribbon cutting” by cutting a paper chain created by kids.
• A Confluence of Thoughts – Add your reflections to the community “guest book” and display board.
• River Time Capsule – Contribute a river-related item, such as a river photo or a note about today’s river, to be memorialized for the future.
• Partner Activities – Each nonprofit will host an activity outside its office. For example, RiversEdge West will offer seedball making.
• Building Tours – See inside the Confluence Center and learn how this space will serve the community for decades to come.

Light snacks and refreshments will be provided.
