These eight studies include survey (6), monitoring (1), and State Historic Preservation Officer (SHPO) concurrence studies. Another 28 overview studies provided by the NWIC are also listed in Table A. All studies are listed by S Number in Table A while the record search is provided as Attachment C Table A: Results of Record Search Reference S No.1 Type of Study Previous Studies in the Project Area Chavez (1990) 12439 Survey Marlow et al.

Historic maps depicted in Lenzi et al. (2018:10‐13) clearly show the portion of the WPCP with solar panels and the current WPCP project area to have been situated within what was once a broad marshy area, or intertidal mudflat, which existed around the edge of the Bay long ago. These maps indicate that the current landform is higher in elevation than the original intertidal mudflat because it has been elevated with fill sediment. Aerial photos available online (NETROnline 2021) clearly show that the western portion of the current project area where the entire pond exists was covered by water in a 1946 aerial photograph. This intertidal inundation covered almost all of the area that is currently the golf course southeast of the airport and north of the current project area. In the 1946 photograph, only the easternmost narrow linear part of the current project area was out of the water. A 1958 aerial photograph shows the area was still below water, although a berm had been extended westward through the bay in a nearly linear extension of Davis Street, with what appears to be the Bay on the south of the berm and an intertidal area on the north of the berm where the golf course and WPCP pond area were later constructed using fill. Thus, the current pond portion of the project area has been created entirely of fill material in what was originally subtidal marshland, while the eastern portion of the current project area is located at the edge of the marsh within what was once an intertidal area. Native American Consultation After being contacted by LSA, the NAHC responded on November 18, 2020, stating that the SLF contained no specific site information for the project area. The NAHC also provided a list of Native American contacts with knowledge of cultural resources in the area and suggested that they be contacted for information. The NAHC response and list of contacts is provided as Attachment D.
