This document is an archaeological investigation report written for the Space Launch Complex 5 Phantom Space Project. The report discusses the work performed by Applied Earthworks consisting of a surface survey covering the Space Launch Complex 5 facility within the area of direct impact (ADI). Additionally it discusses the subsurface survey of the ADI except the areas where demolition of the previous SLC-5 facility, prior grading, and/or very steep topography precluded the presence of intact sites. The archaeological site CA-SBA-2934 was also evaluated to determine its eligibility to the National Register of Historic Places. It also examined the subsurface deposits at three previously identified isolate locations near the project area, but outside the area of potential effect (APE). In consultation with Vandenberg SFB cultural resources personnel, no testing was performed in the portion of NRHP-eligible CA-SBA-670 within the ADI because Project activities within this site would be limited to clearing vegetation from the existing pavement. The report concludes that surface and subsurface survey identified no previously unrecorded archaeological sites and one new isolated artifact. Subsurface survey revealed that, likely due to ground disturbance associated with the demolition of SLC-5, CA-SBA-2934 is no longer present. Subsurface testing also confirmed that all of the isolated artifacts are truly isolated and not part of archaeological sites. In summary, testing for the Phantom project did not yield any archaeological materials. With installation of protective fencing to ensure that Project activities do not leave the paved road through CA-SBA-670, the Project would have no adverse effect on historic properties.
