Fredonia Flood Retarding Structure

Rehabilitation Fact Sheet

Project Name: Fredonia Flood Retarding Structure (FRS)

Sponsors:

  1. Town of Fredonia
  2. Fredonia Natural Resource Conservation District

Project Location: Northern Coconino County, Arizona

Authorization: Watershed Protection and Flood Prevention Act, Public Law 83-566, as amended, and Public Law 106-472, Small Watershed Rehabilitation Amendments of 2000.

Project Summary:

The Fredonia Flood Retarding Structure (FRS) was originally constructed by the Soil Conservation Service (now the Natural Resources Conservation Service–NRCS) in 1973. It is currently operated and maintained by the Town of Fredonia. The 1.8-mile-long earthen structure provides flood protection to the Town of Fredonia, Arizona, including residents, streets and highways, residential and commercial properties, and Prime Farmland.

The FRS has known inadequacies due to settling of the dam crest and transverse cracking in the embankment. To address these issues, the Project Sponsors, with assistance from the NRCS, are developing a Supplemental Watershed Plan and Environmental Assessment (Plan/EA). The Plan/EA will call for rehabilitation of the Fredonia FRS to provide for continued flood protection while meeting current safety and performance standards.

The Dam Rehabilitation Program administered by NRCS provides financial and technical assistance to help local Sponsors rehabilitate aging dams that were originally constructed with NRCS Watershed Program assistance. NRCS, Sponsors, and the Arizona Dam Safety Office are currently working on nine high priority dams needing rehabilitation. In order to receive federal funds for dam rehabilitation, local Sponsors must provide 35 percent of the total project costs.
