Yosemite Lodge Replace Covered Walkway Roofs

Yosemite National Park » Yosemite Lodge Replace Covered Walkway Roofs » Document List

The purpose of this project is to replace the Yosemite Lodge covered walkway roofs. The current roof system has failed and allowed water to infiltrate the wood structure, resulting in rot and decay. This work is necessary to preserve and repair the wood portions to provide the guests with the covered walkways that have been a major component of the Yosemite Lodge experience. In the winter, the leaking water creates icy walkways causing a safety issue for guests and employees. Utility lines are exposed to weather causing premature deterioration, and are visible to guests in an unsightly manner. The entire roof system has outlived its useful life.

The goal of this project is to provide safe, sustainable and waterproof covered walkways at Yosemite Lodge, without the need for further component renewal until at least 2017.

A section of the tour bus unloading area located across Yosemite Lodge Drive will be used for a materials staging area.
