SOIL HAULING

Yosemite National Park

1. BACKGROUND AND OBJECTIVES

Yosemite National Park is ecologically restoring a floodplain in Yosemite Valley north of Lower Pines Campground. In support of this operation, 3,900 cubic yards of soil must be hauled from immediately north of Lower Pines Campground in Yosemite Valley to the Upper River staging area in Yosemite Valley, in October and November 2023. Options are included should additional work be necessary to complete project requirements.

2. REQUIREMENTS

2.1. Requirement A: Load and Haul 3,000 Cubic Yards of Soil from north side of Lower

Pines Campground

Option A-1: Load and Haul up to 900 Cubic Yards of Soil from north side of Lower Pines Campground

The Contractor will be responsible for loading, hauling, and delivering soil from the north side of Lower Pines Campground in Yosemite Valley to the Upper River Staging Area in Yosemite Valley, a round trip of approximately 4 miles (see attached Map). The Contractor shall provide the dump truck and loader.

The material to be removed will be piled on the north side of Lower Pines Campground in an area accessible by tandem dump trucks and loaders. The material is a sandy loam with up to 50% coarse gravel (1 to 3-inch diameter) and less than 1% boulders (less than 4-inches in diameter).

There is a small ephemeral stream crossing to access the soil pile. NPS will build a small temporary ramp to improve access for contractor trucks using soil from the pile. The contractor will be responsible for removing and hauling away any fill used for the ramp and match the adjacent existing grade.

The Contractor shall consult with the COR on where to dump and pile soil at the Upper River Staging Area delivery site. The Contractor will be responsible for building up pile(s) with a loader as needed to maintain the pile(s) in the designated area.

Soil may be hauled from the work site between the hours of 6:00 a.m. and 6:00 p.m., 7 days a week, and includes the following restrictions:

Hauling must be conducted after October 16, 2023, when the Lower Pines Campground is closed for the season. We recommend as much hauling as possible is done immediately after October 16th to avoid the potential for fall snowstorms covering the pile to be hauled.
