Mariposa Grove PHASE 5 – Lower Grove and South Lot (2016 to

Location: Yosemite National Park

Overview: Through the winter of 2016 (5’ of snow at one point) and into 2017 we constructed two new buildings and two new bus shelters for the Mariposa Grove at the south entrance to Yosemite National Park on Highway 41.

One of the two buildings and a bus shelter is located at the Lower Grove Arrival Area which serves as the drop off point for hiking and touring through the massive Mariposa Grove of Giant Sequoias.

The other larger building and bus shelter are located at the South Entrance to the park. The building serves as the Visitor Center including a sales area and a comfort station. The buildings and bus shelters are a combination of timber framing, log infrastructure, cedar siding, exposed wood ceilings with stonework to protect the buildings from snow exposure.

Treeline’s role: The original construction of the new structures was entirely subcontracted to Treeline, who self-performed all aspects within Divisions 1, 3, 4, 5, 6, 7, 8 & 10 including all quality control, safety, and project management. The reconstruction of Lower Grove comfort station after a tree fell on it in January of 2020 was entirely subcontracted to Treeline. We performed divisions 1, 2, 3, 4, 5, 6, 7,
8 & 10.


Note: Although the project was remote, the Visitors Center and Parking lot is directly adjacent to the South Entrance of the Park on Hwy 41. As this is the Southern Gateway into the Park, it is highly visible. Maintaining good clearances for the public to view our progress was important, and extra effort was made to construct the front entrance to the Visitors Center sufficient enough so that the public could get a good idea of the design of this new Park asset as construction continued.
