2025-11-03 PL-CRC-2025-000038 HIFL Draft AIS Testing Strategy

Home

(T-006 and T-007) and metal and concrete pipe infrastructure (T-008) associated with wastewater treatment facilities were identified in the portion of the project area at PACRC, and a concrete culvert(T-009) and two historic buildings were identified at UHH (T-010,the Wentworth Building and T-011,the Business Education and Technology Building) (Figure 32, Figure 33). The proposed AIS testing strategy for the Hawaii Island portion of the project area consists of five (5) test trenches (PH-01 through PH-05), each measuring 5 m long by 0.7 m wide.Two test trenches target the PACRC portion of the project area and include one test trench in the location of the BMH (PH-01) and one test trench (PH-02) along the proposed conduit near the existing infrastructure connection(Figure 34,attached).Three test trenches (PH-03 through PH-05) target the UHH portion of the project area and are generally distributed across the area of proposed ground disturbance,including one within the footprint of the CLS and two along the conduit for the utility connections (Figure 35, attached). We are requesting SHPD's concurrence that the proposed testing strategy for the HIFL Project is appropriate.We look forward to hearing from you soon regarding this request. Please do not hesitate to contact me if you have any questions or require additional information. Sincerely, Mara A.
