Yosemite Valley Integrated Improvement Utilities Master Plan Phase 2B - North Pines Campground

Yosemite National Park » Yosemite Valley Integrated Improvement Utilities Master Plan Phase 2B - North Pines Campground » Document List

Phase 2B is part of the larger Yosemite Valley Utilities Improvement Master Plan. It would replace and consolidate the East Yosemite Valley utility lines that were damaged in the 1997 flood. The eroding process has moved the river bank next to the North Pines Lift Station and undercut the manhole associated with it, exposing under-river utility crossings. Phase 2B would replace the lift station, which is in the North Pines Campground. The North Pines Lift Station and its associated under-river utilities (at the junction of Merced River and Tenaya Creek) must be relocated before they fail and spill sewage into the Wild and Scenic Merced River.
Scope of work:

•Relocate the North Pines Lift Station to the entrance near the kiosk
•Re-grade the gravity sewer mains
•Replace the primary power lines
•Keep the existing water lines in the North Pines Campground and in the stables area
•Replace the comfort station in the Backpackers Campground with vault toilets
In April 2009, the Plaintiffs approved the use of the North Pines Amphitheater Utility Corridor to allow North Pines Lift Station relocation and under-river utility crossings abandonment.
