Confidential – Class 1 Railroad

Project Location

San Bernardino County, CA

TRC provided permitting services pursuant to the Clean Water Act and State Fish and Game Code for the renewal of five Class 1 Railway company bridge structures. The bridges are located in the Mojave Desert of San Bernardino County, California along an approximate 117-mile segment of the railway.

TRC coordinated with the U.S. Bureau of Land Management (BLM), the U.S. Army Corps of Engineers (USACE), the Regional Water Quality Control Board (RWQCB) and the California Department of Fish and Game (CDFG) regarding the details associated with the permit package submittals, as well as conducted the Native American consultation for the bridge renewals. TRC staff processed emergency Section 404 Permits from the USACE to meet the Client’s schedule requirements, as well as the other required permits which included a Section 401 Water Quality Certification, a Section 1602 Streambed Alteration Agreement and a right of entry from the BLM.

As part of the permitting process, TRC conducted biological and cultural resources assessments due to the fact that several of the bridges were located within a designated critical habitat for the federally-protected desert tortoise. A jurisdictional delineation was also completed that included an assessment under the new Rapanos Guidelines provided by the USACE. Based on our findings, TRC was successful in having several of the bridges removed from federal jurisdiction. TRC also developed the Habitat Mitigation and Monitoring Plan that outlined the needed mitigation for impacted habitat areas and has assumed long-term responsibility for monitoring the on-site mitigation for the project.
