Title

Mountain Tunnel Improvements Project

Description

The San Francisco Public Utilities Commission (SFPUC) is proposing the Mountain Tunnel Improvements Project (project) to improve the condition of the existing Mountain Tunnel, and to ensure the tunnel's continued ability to reliably convey water to its 2.7 million customers in the Sierra foothills and San Francisco Bay Area. The project is in the central Sierra Nevada Mountain Range near the town of Groveland in Tuolumne County. The tunnel begins at Early Intake Reservoir on the Tuolumne River and extends approximately 19 miles west to Priest Reservoir, near the town of Groveland. Conditions in the tunnel interior vary along the alignment, with unlined sections on the east and concrete-lined sections on the west. *See NOC for full details*
