Pavers available to support The Watershed Nature Center's Access Nature Campaign The Intelligencer FacebookTwitterEmail The Watershed Nature Center’s park improvements are underway, and recognition pavers are now available for purchase. Pavers will be prominently displayed in the Welcome Patio at the entrance of The Watershed Nature Center located at 1591 Tower Avenue in Edwardsville. The installation of the Welcome Patio has been made possible by a gift from the Phillips 66 Wood River Refinery along with an anonymous matching gift. Pavers purchased for the Welcome Patio will be used to revitalize the entrance to the Visitor’s Center with proceeds going directly to the Watershed.
