include the excavation and installation of a BMH within a parking lot area,measuring 23 ft by 17 ft
<br /> by 12 ft deep (7 m x 5.2 m x 3.7 m),and approximately 390 linear ft(118.9 m),at a depth of 4 ft(1.2
<br /> m), for the installation of a fiber optic conduit,extending from the BMH as well as connecting to
<br /> existing utility infrastructure located on Manele Road within the harbor area.The majority of the
<br /> fiber optic conduit between the BMH and utility connection point would be installed via HDD, at a
<br /> maximum depth of approximately 6-8 ft(1.8-2.4m) below ground surface.
<br /> Previous archaeological studies near the Lanai portion of the project area have identified historic
<br /> properties in the vicinity of the project area that reflect Manele's intensive pre-Contact use as a
<br /> village site and burial area.This includes complexes with pre-Contact habitation,agricultural,
<br /> ceremonial,and burial sites. Post-Contact historic properties are mostly related to ranching
<br /> activities and associated infrastructure,such as a boundary wall,well,roadway and trail complex,
<br /> and a cattle chute and holding pen. Much of the surrounding area,including several burial sites,
<br /> were significantly disturbed by bulldozing and other construction activities associated with the
<br /> Manele Small Boat Harbor Project in 1964-65. No historic properties were previously identified
<br /> within the project area (Figure 26). Pacific Legacy completed a field inspection and identified two
<br /> potential historic property features within the Manele Harbor portion of the HIFL project area.
<br /> These include T-004, a concrete ditch, and T-005, a stone wall,both of which are likely related to
<br /> post-Contact ranching activities in the area (Figure 27).
<br /> The proposed AIS testing strategy for the Manele Harbor portion of the project area consists of
<br /> three (3) test trenches (MH-01 through MH-03)(Figure 28, attached).The test trenches include one
<br /> test trench (MH-01) in the location of the BMH and two test trenches (MH-02 and MH-03)which
<br /> target the two short segments of fiber optic conduit trenching at either end of the HDD
<br /> underground conduit.Test trenches MH-01 and MH-02 will measure 5 m long by 0.7 m wide.Test
<br /> trench MH-03 will measure 3 m long by 0.7 m wide.
<br /> Hawaii Cable Landing Site (University of Hawai`i at Hilo Pacific Aquaculture&Coastal
<br /> Resource Center and UH Hilo)
<br /> The proposed cable landfall on Hawaii Island is located at the University of Hawaii at Hilo Pacific
<br /> Aquaculture&Coastal Resource Center (PACRC),located just east of the Hilo Harbor breakwater,
<br /> and the proposed CLS is located at UH Hilo (UHH) (Figure 29, attached). Project ground disturbance
<br /> at the cable landfall will include the excavation and installation of a beach manhole, measuring 23 ft
<br /> by 17 ft by 12 ft deep (7 m x 5.2 m x 3.7 m), and the excavation of approximately 100 linear ft(30.5
<br /> m), at a depth of 4 ft(1.2 m), for the installation of a fiber optic conduit,extending from the BMH to
<br /> existing utility infrastructure located on the grounds of the PACRC. Project ground disturbance at
<br /> UHH will include the excavation and installation of a foundation for a CLS (new modular structure),
<br /> measuring 43 ft by 22 ft by 5 ft deep (13.1 m x 6.7 m x 1.5 m) and an adjacent generator foundation
<br /> pad,measuring 9 ft by 4 ft by 1 ft deep (2.7 m x 1.2 m x 0.3 m), along with the excavation of
<br /> approximately 415 linear ft(126.5 m), at a depth of 3 ft(0.9 m),for the installation of conduits for
<br /> utility connections between the CLS and existing infrastructure at UHH.
<br /> Previous archaeological studies in the PACRC portion of the project area have documented
<br /> architectural features associated with post-Contact development of Hilo and Keaukaha.They
<br /> include the Hilo Breakwater, Hilo Harbor, Hilo Railroad Company tracks, Peter Arioli House,
<br /> Kahauolupua House, St. Mary's Gate of Heaven Church,Kuhio Memorial Chapel, and Kamehameha
<br /> Hall. In the vicinity of the UHH campus, previously identified features are associated with post-
<br /> Contact agricultural activities,and include platforms,mounds, modified outcrops,linear walls, pit
<br /> features, enclosures, and drainage features.The majority of these features are associated with
<br /> sugarcane cultivation by the Waiakea Mill Company, as well as the Hilo Dairy Facilities (Figure 30,
<br /> Figure 31). Pacific Legacy completed a field inspection of these areas and identified six potential
<br /> historic property features, including two historic buildings. Rectangular and circular concrete tanks
