White River Amphitheatre
Civil Engineering, Land Surveying, Tribal | 53 acres
Located on the Muckleshoot Indian Reservation, the White River Amphitheater is an iconic music venue in the Pacific Northwest. The $30 million project was built in 2003 by the Muckleshoot Indian Tribe as their gift to music enthusiasts.
Barghausen provided civil engineering and land surveying services for the amphitheater in 1997. This project started with the relocation of a building on site that was used as the tribe's substance counseling center. The site required the removal of several cobblestones, boulders, shallow drainage swales, and existing fences.
Our engineering team prepared plans for grading, drainage, TESC, fire line extensions, sanitary sewer extensions, and stormwater detention systems. Stormwater plans included centralized detention ponds and conveyance systems. The existing amphitheater canopy was located near existing artesian wells with groundwater elevations nearly reaching the surface. A sub-drainage system was required to help decrease groundwater impacts. 53-acres of the site was converted into gravel and paved parking areas.
