This document is a Section 106 report that addresses the potential for effects to significant historic properties as a result of construction activities related to the repair and restoration of Space Launch Complex 4 (SLC-4) at Vandenberg Air Force Base (VAFB), Santa Barbara County, California. The report discusses archival searches and literature reviews, intensive pedestrian surveys, and testing and evaluation programs performed in support of the project. The historic properties investigations identified five prehistoric archaeological sites in the vicinity of the proposed undertaking. In addition, the Spring Canyon wetland was identified as a significant cultural property by members of the local Chumash reservation. As a result of the archaeological study and in response to Chumash sensitivity concerning the wetland resource and cost factors related to both of these, the USAF redesigned the fence alignment, construction, and maintenance plan to remove the proposed fenceline from the floor of Spring Canyon and to eliminate a 600-m clear zone.
