Wailea, HI Coastal Erosion Rate
What USGS measures 1.4 miles northwest of Wailea, HI
1.4 miles northwest of Wailea, HI: USGS's transects didn't pick up a trend here that beats the survey's own uncertainty. That's the majority case nationally, and for this stretch specifically it means the coast is holding, not that the data failed to find anything.
What "Wailea" means on this page
This is a roughly 3.5-mile stretch of coast, not one address or parcel - USGS's own transects run every few hundred feet, but that's finer than any one property needs, so this page reports the stretch nearest Wailea, HI. Centered near 20.70°N, 156.44°W. Survey years: 2007-2010, method WLR, from USGS's Hawaii shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
Where this fits nationally
This reading comes from 184 individual transects averaged together, 85% of which measured erosion rather than growth. USGS's confidence interval here is ±0.43 ft/yr. Taken at face value, this segment's raw -0.12 ft/yr reading would land it 618 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2011-1009. Fort Dick, CA sits at national rank 970 for growth (0.32 ft/yr), one reference point among the 1211 scored segments, 2378 miles from here. 3.5 miles up the coast, Kihei, HI shows the same lack of a significant trend.
