Kekaha, HI Coastal Erosion Rate
Shoreline change 8.6 miles north of Kekaha, HI
Nothing alarming measured 8.6 miles north of Kekaha, HI: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.
What "Kekaha" means on this page
Kekaha, HI is the nearest named place, 8.6 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 22.09, -159.76. USGS's Hawaii assessment last surveyed this stretch through 2007-2010, computing the rate with its WLR method. Other US regions were surveyed in different years, sometimes decades apart, so this page states its own rather than implying one national vintage.
Where this fits nationally
This reading comes from 185 individual transects averaged together, 57% of which measured erosion rather than growth. Uncertainty on this specific number: 0.97 ft/yr either side. The unadjusted figure here, -0.04 ft/yr, would place it 729 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2011-1009. Rank 1021 nationally for growth belongs to Costa Mesa, CA, 2656 miles from this stretch, measured at 0.48 ft/yr. 1.4 miles away, Kekaha, HI is the nearest other measured stretch: also no significant trend.
