The Honokōwai study area extends from the revetment fronting Mahana Condominium at Honokōwai Point north to the start of hardened shoreline at Laeokama Point (transects 1181 – 1272). The shoreline is comprised of narrow white sand beach, most of which is backed by hardened shoreline and sea walls built to protect several hotels and condominiums from shoreline change. Offshore is dominated by beach rock shelves and fringing reef.
As a whole, the area (transects 1181 – 1272) has experienced moderate erosion since 1912 with an average rate of -0.5 ft/yr. Honokōwai Beach Park (transects 1221 – 1228), central to this area, has experienced moderate erosion over time with an average rate of -0.4 ft/yr. 2007 imagery reveals sandy beach in the north of the study area (transects 1266 – 1272) not present in older imagery, yet is indicated on the 1912 T-sheet. The long-term
average rate of this section indicated mild erosion at -0.1 ft/yr.
