Humbug Creek and Willow Creek Wetland Restoration

Folsom, California

Humbug Creek was historically dredger mined, completely removing the natural creek channel and replacing the creek and floodway with piles of large cobbles, sand, and debris. While some revegetation of the creek corridor occurred naturally, a second round of mining – this time using the cobble piles as a source for aggregates and gravels – occurred in the late 1970s, further disturbing the site. Foothill Associates designed approximately ten acres of seasonal marsh, perennial marsh, and open water habitat to restore wetland functions in several locations in the Humbug Creek corridor and the adjacent Willow Creek corridor. We provided construction supervision during the implementation of the wetland restoration. The five-year monitoring program, conducted by Foothill, for the restored wetlands showed development of aquatic habitat and natural recruitment of woody riparian species that met or exceeded project goals.
