Conducted for SANDAG and located along 1.6 miles of North County Transit District (NCTD) railroad right-of-way (ROW) in Del Mar, CA, the study was performed to document archaeological and historical resources and potential for impacts within the project boundaries for NHPA Section 106 compliance. This project was subject to National Environmental Policy Act (NEPA) review. The U.S. Army Corps of Engineers (USACE) was the Federal review agency for this project in compliance with Section 106.
PanGIS staff reviewed previous cultural documentation, conducted a Sacred Lands Search, Native American outreach, performed a Class III survey for archaeological and historic-era resources in the Area of Potential Effect (APE), made significance recommendations for NRHP/CRHR for historic-era structures in ROW, authored technical reports, attended agency meetings, and created GIS exhibits. PanGIS Architectural Historian completed four NRHP evaluations for historic-era structures with SHPO concurrence.
Prior to the survey, PanGIS staff obtained current documentation of Roadway Worker Protection training, a NCTD Right of Entry permit, and scheduled an NCTD-supplied flagger for the duration of the survey. During the survey, PanGIS staff recorded or updated sixteen archaeological sites. Most of the sites are associated with the 1910 construction of the AT&SF railway, including historic retaining walls, drainage systems, foundations, pilings, and trash scatters.
