This project was conducted for SANDAG 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. It consisted of a review of previous cultural documentation, Native American outreach, a pedestrian survey of the Area of Potential Effect (APE), an update of all previously recorded resources within the project area, preparation of two technical reports, and four NRHP evaluations of historic-era resources. 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 of the National Historic Preservation Act of 1966 (as amended) and its implementing regulations at 36 CFR Part 800.
Prior to the survey, PanGIS staff had to ensure they had current documentation of Roadway Worker Protection training, obtain a NCTD Right of Entry permit, and schedule 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. PanGIS Architectural Historian completed four NRHP evaluations for historic-era structures with SHPO concurrence.
