Wawona Hotel Fountain Rehabilitation

Yosemite National Park » Wawona Hotel Fountain Rehabilitation » Document List

The fountain in the center of the formal entry drive to the Wawona Hotel National Historic Landmark has partially collapsed. This project would restore the fountain to its 1918 appearance. The skilled staffs of Yosemite National Park and the concessioner propose a design/build approach to rehabilitate the fountain within its current design vernacular. A sustainable design has been conceptually developed to include water conservation features.
The existing stone fountain would remain intact, but the damaged and collapsed sections would be removed and repaired. The fountain would be dug between the depths of 24 inches to 30 inches. A layer of Bentonite (clay) would be installed as a watertight liner. The liner would be covered with new gravel to match the historic appearance and would not be seen from above. Existing stone would be reused to match the original construction as closely as possible. New steel-reinforced rods would be installed and hidden within the masonry. The stone and grass edge would be rehabilitated to match existing form. New piping would run from existing water lines along the edge of the hotel, to the outer edge of the fountain, and into a new 4' x 4' concrete vault that would be installed inside the fountain basin. A smaller 18" x 18" electrical box would be placed near the western edge of the fountain basin curb. All work would be photo-documented prior to removal or demolition during construction and after completion.
The project would include repair, replacement, and upgrade of existing waterworks components including subsurface plumbing, backflow prevention, pressure pipe, and fountain nozzle. The scope of work also includes waterproofing the current fountain basin and installing a new energy efficient pump. The one-inch plastic water line, located between the fountain and the front of the main building, may be reused; however, to accommodate a new electrical supply line for the new pump, a 12 inch wide by 24 inch deep trench would be dug next to the existing water line for a distance of approximately 100 feet.
Repairs to stone work would incorporate appropriate historic preservation techniques according to the Secretary of the Interior's Standards for the Treatment of Historic Properties. This project is proposed to be a partnership among the Yosemite Fund, the concessioner, and Yosemite National Park
