Hillside Mine Remediation

Rich gold and silver were discovered at the Hillside Mine in 1887. Mining activity ceased in the mid-1950s leaving behind continual erosion of tailings into nearby Boulder Creek, adversely impacting water quality. The project goal focused on a sustainable and long-term solution. Rather than importing soils, AECOM identified on-site locally derived rock to protect the evapotranspiration cover from erosion along Boulder Creek during flood events.

“Thank You” AECOM for designing a long-term solution and reclaiming a site that will ultimately blend into the natural surroundings.
