The North Kāʻanapali study area extends continuously from Kekaʻa Point (Black Rock) north to the revetment fronting the Mahana Condominium at Honokōwai Point (transects 1069 – 1180). The coastline is comprised of a long white sand beach backed by hotel and condominium developments in the north and south. Offshore, a fringing reef system dominates the northern portion of the area near Honokōwai Point, while the central and southern portions have steep nearshore slopes that extend to deeper offshore sand and rock patches.
Overall, the area has remained relatively stable since 1912 with an average rate of 0.0 ft/yr. The northern portion of the area (transects 1132 – 1180) shows mild long-term erosion with an average rate of -0.3 ft/yr. The southern portion (transects 1069 – 1131) of the area is exposed to the majority of seasonal swell events and kona storm activity. As a result, the position of the shoreline is highly variable through time and exhibits a long-term trend of mild accretion with an average rate of 0.3 ft/yr.
