O’Neill Regional Park Amphitheater Replacement

Project Summary: The proposed project consists of the redesign and expansion of an existing 20-year old, 50-seat amphitheater adjacent to the park’s Nature Center. This is needed because seating capacity is limited and does not serve average attendance, which often exceeds three times the amphitheater’s capacity. The proposed project increases seating capacity to 120, with access and designated seating in compliance with ADA standards. Pathway lighting will be installed along the tiered seating area and the site will be regraded to create terraced seating that is adequately sized for all guests. The project also includes native landscape planting to enhance the park’s natural setting, and additional canopy trees will be planted on the periphery of the seating area to provide shade.
