Rehabilitating and Replacing Pipeline in a Sensitive Environment
North Coast System Rehabilitation, Phase 3 – Coast Segment | Santa Cruz, CA
LSA prepared environmental documentation consistent with CEQA, including a biological and cultural resources assessment for the North Coast System Rehabilitation Project Phase 3 – Coast Segment Project. The project is part of the North Coast System Rehabilitation Program to rehabilitate and replace the 18-mile pipe network and diversion structures that provide the City’s water supply. The project would replace 16,000 feet of water main along the Pacific Coast Highway north of the City of Santa Cruz. The project is located within Wilder Ranch State Park on land currently leased for agricultural production. LSA performed field work, prepared technical reports for biological and cultural resources, and prepared an Initial Study/Mitigated Negative Declaration.
In 2015, LSA prepared permit applications for regulatory agencies including: a biological resources assessment report, U.S. Army Corps of Engineers (USACE) nationwide permit application, Regional Water Quality Control Board Water Quality Certification application, California Department of Fish and Wildlife Streambed Alteration Agreement application, and mitigation and monitoring plan.
The project is situated in an archaeologically sensitive area and would impact prehistoric archaeological site CA-SCR-10. A cultural resources study addressed the USACE requirements under Section 106 of the National Historic Preservation Act. The study consisted of background research, including a records search at the regional Information Center at Sonoma State University, a field survey, a limited auger excavation at CA-SCR-10, and a report. LSA’s study identified a previously unrecorded portion of CA-SCR-10, a shell midden and lithic scatter, and recommended mitigation measures.
