The Preservation Plaza Stage offers a one-of-a-kind concert setting with the backdrop of West Lake Okoboji’s blue waters glistening in the background. The desire by the Historic Arnolds Park Incorporation (HAPI) and RDG Planning & Design to transform the area into a permanent event space has been realized from what was previously a green space frequented by lake goers for events. Through a Zahner Assist engagement, Zahner worked with RDG to develop and refine the 6,400 square foot amphitheater that resembles the lake waves above and wooden boat hulls below. Nestled within the structural steel bays are Zahner’s patented aluminum ZEPPS. The structure finishes out with custom finished stainless steel flat seamroof panels, painted aluminum perimeter fascia, and columns covers.
