• The proposed gravity sewer line corridor within the Hina Lani Street ROW; and • The proposed force main sewer lines corridor located makai of Queen Ka'ahumanu Highway in TMK (3) 7-4-008:072. All project staging will be confined within the APE limits shown in Attachment A. Cultural, Historical,and Archaeological Background Cultural Surveys Hawai`i, Inc. (CSH) completed a literature review and field inspection(LRFI) for the current undertaking(Bautista et al. 2021) for inclusion in the project's Draft EA. The LRFI was designed to determine the likelihood that historic properties may be affected by the project and, based on findings, consider cultural resource management recommendations to facilitate project planning and support the project's historic preservation and environmental review compliance. The literature review identified 29 previously identified historic properties situated within approximately 30 m of the project APE (Attachment C); of these, 19 sites are indicated within the APE bounds. Site types include pahoehoe excavations,trails, mounds, lava tubes,cairns, enclosures, walls, a modified outcrop, petroglyph, pecked pahoehoe basin, and battered area. Site ages range from pre-Contact through the historic era. One of the trail sites, SIHP # 50-10-27- 18099, is the centerpiece of an archaeological preservation easement on the fore ier 1,anihau property (current ownership is West Hawaii Business Park, LLC) referred to as the "Honokohau Historic Trail" interpretive complex (Tuggle and Tomonari-Tuggle 2008). This interpretive complex also contains a portion of the Mamalahoa Trail that does not overlap the APE bounds. The field inspection tentatively confirmed the presence of eight historic properties within the APE: SIHP#s 50-10-27-00002, -18084, -18095, -18099, -21588 (and likely an overlapping segment of-23023), -23026 (one of five component features), and SP-3 (Attachment B). SIHP # -18083 was not confirmed during the field inspection but may still be present within the pump station parcel. SIHP# -18097 is a large complex bisected by the pump station construction access corridor, however, none of its component features were observed within the project corridor. A branch of the SIHP # -23353 trail extends through the southeastern corner of the pump station parcel; while this branch was not found during the field inspection, its location was subsequently confirmed with Rick Gmirkin of Ala Kahakai National Historic Trail in March 2022 and therefore it is also depicted in Attachment B. The LRFI study noted that, while no newly identified potential historic properties were observed during the field inspection, there remains some potential for the discovery of additional sites during a more intensive survey, given the poor ground visibility, particularly within the pump station site. The results of the literature review indicated additional archaeological work may be warranted for the North Kona SPS Project in order to obtain a project finding of"no adverse effect" in accordance with federal regulations(36 CFR 800.5).
