Ackerson Meadow Restoration Project

Request for Proposal for Wetland Restoration Services

Project Description

In collaboration with Yosemite National Park (YNP) and the Stanislaus National Forest (STF), American Rivers is completing work to restore Ackerson Meadow along Ackerson Creek in Tuolumne County.

The Ackerson Meadow Restoration Project will restore the 230-acre Ackerson Meadow complex, improving hydrologic function and ecological condition. The Ackerson Meadow complex is made up of main Ackerson Meadow and South Ackerson Meadow, which are 160 and 70 acres respectively. These meadows and Ackerson Creek have been subject to significant land use over the last 160 years, resulting in significant erosion and gully development within the meadow and Ackerson Creek. The project includes multiple tasks, but the primary activities are filling the gully with soil and organic materials, constructing a rock grade control structure to secure the gully fill materials, and installing native plant materials. 

Through this Request for Proposals, American Rivers seeks proposals describing the prospective firm’s qualifications, approach, and cost estimate for wetland restoration services to complete implementation of meadow restoration and other activities included in the Scope of Work at Ackerson Meadow. The selected contractor will work closely with American Rivers, YNP, STF, and Evan Wolf LLC to complete the Scope of Work.
