The Baldwin Park study area extends from Wawau Point east to Mantokuji Bay in Lower Pāʻia. The shoreline of this area consists of sandy beach broken by rock outcrops and revetments. Offshore, fringing reef and several beach rock benches buffer small sections of the shoreline from high-energy north swell. H.A. Baldwin Park is located in the center of the study area. The revetment protecting the now defunct lime kiln divides the study area into two sections, Baldwin Beach and Lower Pāʻia, for description purposes. The whole study area (transects 687 – 819) has experienced, on average, moderate erosion with an average rate of -0.7 ft/yr. Baldwin Beach (transects 686 – 754), the largest sandy beach in the study area, is located west of the lime kiln revetment (transects 754 – 762). It is backed by lowlying sand dunes separating it from the Maui Country Club golf course. Offshore, on each end of Baldwin Beach are beach rock benches partially protecting the adjacent shoreline from the majority of north swell. Baldwin beach overall has experienced moderate erosion with an average rate of -0.6 ft/yr with some areas experiencing severe erosion of up to -4.9 ft/yr (at and around transect 747).
East of Baldwin Park, around the lime kiln revetment is Lower Pāʻia. There are two sections of sandy shoreline in Lower Pāʻia, separated by Fly Water Point, a basalt headland. Pāʻia Bay (transects 762 – 800) has experienced light to moderate erosion with an average rate of -0.6 ft/yr. Mantokuji Bay, (transects 810 – 819), has experienced moderate to high erosion over time with an average rate of -1.5 ft/yr. No analysis was done fronting the defunct lime kiln due to insufficient data.
